Description

Method of providing data and electronic device supporting same

Various embodiments of the present invention relate to a method for providing data and an electronic device supporting the same.

Electronic devices such as smart phones can exchange data between electronic devices in various ways. For example, the electronic device can generate data as a code image (e.g., a bar code or a QR code (quick response code)) and display it on a display. In addition, an external electronic device can recognize the code image using a device (e.g., a camera) that can recognize the code image and obtain data corresponding to the code image. However, in the case of a bar code, since the amount of data that can be transmitted through a code image is significantly small, a QR code that can include more data than a bar code is mainly used recently.

However, when transmitting a large amount of data through a QR code, the patterns within the QR code become densely packed in order to include the large amount of data in a QR code of a specified size, which may cause the recognition rate of the QR code to decrease.

Various embodiments of the present invention can provide a data providing method and an electronic device supporting the same, which divides data into a plurality of pieces when the size of the data is greater than a specified value, generates a plurality of code images corresponding to the divided data, and sequentially displays the generated plurality of code images on a display in the order of the divided data.

An electronic device according to various embodiments of the present invention comprises a display, a communication module, a processor and a memory, wherein the processor is configured to divide the data when the size of the data is greater than or equal to a specified value, generate a plurality of code images corresponding to each of the divided data, designate a display order of the generated plurality of code images, display a code image whose display order corresponds to a first order among the plurality of code images in a specified area of the display, and, when a specified signal is received from an external electronic device through the communication module, display a code image whose display order corresponds to a next order among the plurality of code images in the specified area.

Among the plurality of code images, a code image whose display order corresponds to a first order may include an electronic device including information about the plurality of code images.

In addition, in a method for providing data according to various embodiments of the present invention, if the size of the data is greater than or equal to a specified value, the method includes an operation of dividing the data, an operation of generating a plurality of code images corresponding to each of the divided data, an operation of specifying a display order of the generated plurality of code images, an operation of displaying a code image whose display order corresponds to a first order among the plurality of code images, in a specified area of a display, and an operation of displaying a code image whose display order corresponds to a next order among the plurality of code images, in the specified area when a specified signal is received from an external electronic device through a communication module, wherein a code image whose display order corresponds to a first order among the plurality of code images may include information in the plurality of code images.

According to various embodiments of the present invention, when data is greater than a specified value, the data is divided and a plurality of code images corresponding to the divided data are generated, thereby providing a highly accurate code image that prevents a phenomenon in which a recognition rate is lowered when an external electronic device scans the code image.

In addition, according to various embodiments of the present invention, the security of a plurality of code images can be supplemented by including information about the plurality of code images in a code image corresponding to the first order to be displayed according to the display order among the plurality of code images.

In addition, various effects may be provided that are directly or indirectly identified through this document.

When dividing the data, the processor may divide the data based on at least one of information about the number of at least one piece of information included in the data, information about the type, and information about the size.

In addition, the processor can distinguish between image information and text information included in the data, and generate a plurality of code images based on information about the type (e.g., type) of information included in the data. When generating the plurality of code images based on the type of information, a code image including only image information can be generated, and a code image including only text information can be generated.

The processor may, in the operation of generating the plurality of code images, cause a code image corresponding to a first order among the plurality of code images to be output through a display (e.g., the display (201) of FIG. 2) to include information about the plurality of code images. The information about the plurality of code images may include, but is not limited to, usage permission information about specific information and information about a communication method. The usage permission information about the specific information may be information that allows only an authorized device to obtain specific information in relation to information requiring security among the information included in the plurality of code images. The usage permission information may include, but is not limited to, identification information of a pre-designated external electronic device among the plurality of external electronic devices (e.g., a Mac address of a Samsung electronic device) or identification information about a user who can obtain the security information (e.g., an account of a user using the external electronic device). The information about the plurality of code images may include, for example, information about the total number of the plurality of code images, the type (e.g., type) of information included in each of the plurality of code images, and the capacity of data included in each of the plurality of code images. Information about the communication method for the above may be information that is preset as to which communication method the electronic device (200) and the external electronic device will use to transmit and receive data. The communication method may include NFC (Near Field Communication), Bluetooth, or Wifi-direction, and is not limited thereto as long as the electronic device (200) and the external electronic device can communicate via a wired/wireless network.

In operation 305, the processor can display a code image to be displayed in a first order through the display among the plurality of generated code images. The code image corresponding to the first order can be displayed in a designated area that is at least a portion of the display.

According to one embodiment, the processor may display a first code image among the plurality of code images in a designated area of the display (e.g., the display (201) of FIG. 2). When the number of the plurality of code images to be displayed in the designated area is 13 in total, the processor may cause information about the plurality of code images, including information about the total number of the plurality of code images, to be included in the first code image. The processor may display the first code image in the designated area, for example, in a window of an application executed in the electronic device. In addition, the electronic device and the external electronic device may transmit and receive the designated signal based on information about a communication method included in the information about the plurality of code images. For example, when the information about the communication method is set to information related to Wi-Fi, the processor of the electronic device may receive the designated signal through a Wi-Fi communication channel with the external electronic device.

In operation 307, the processor may receive a designated signal (e.g., an ack signal) from an external electronic device through a communication module (e.g., the communication module (202) of FIG. 2). The processor may receive the designated signal based on information about a communication method of information about a plurality of code images included in a code image corresponding to a first code sequence scanned by the external electronic device. The processor, which has received the designated signal, may display a code image corresponding to a next sequence of the code image corresponding to the first sequence on a designated area of the display. The display order of the plurality of code images to be displayed on the designated area may be set based on the priority of at least one piece of information included in the data. According to one embodiment, the code image displayed by the processor through the display may include data related to a contact. The data related to the contact may include basic address book information (e.g., basic information) such as a user's address information, name information, and phone number information, and image information (e.g., additional information) such as a photo or video. The processor may display data related to the contact as a plurality of code images through the display based on the priority of information included in the data related to the contact. For example, the processor may display each of a plurality of code images including information of a size of 10 kb through a designated area of the display. When the size of the basic address book information is 8 kb and the size of the image information is 20 kb, the processor may include the basic address book information having a size of 8 kb in a code image corresponding to a first order among the plurality of code images and display it in the designated area of the display.

When the processor receives the specified signal from the external electronic device, the processor may divide the image information having the size of 20 kb into first image information and second image information having the size of 10 kb. The processor may include the first image information in a second code image to be displayed in the next order of the first code image and display the first image information through the specified area. When the processor receives the specified signal from the external electronic device, the processor may include the second image information in a third code image to be displayed in the next order of the second code image and display the second image information through the specified area. That is, the processor may divide the information included in the data into basic information and additional information by dividing the fields. As another example, the processor may preferentially include information (e.g., basic information) for which data communication is easy and fast among the plurality of pieces of information included in the data in the first code image and output it. Thereafter, the processor may divide other information (e.g., additional information) larger than the size of information that can be stored by one code image and include it in a plurality of code images and output it.

According to one embodiment, when information on a communication method of information on a plurality of code images included in the first code image is set to Bluetooth, the processor may receive the specified signal from the external electronic device via Bluetooth communication. According to another embodiment, the processor may output the first code image via the specified area. When the external electronic device recognizes the first code image, it may broadcast a signal indicating that it has recognized the first code image. The processor may receive a signal notifying that it has recognized the first code image from the external electronic device via a BT beacon. The processor may confirm that the external electronic device has recognized the first code image based on the signal received via the BT beacon, and may change the first code image displayed via the specified area to a code image corresponding to the next order. When the processor receives the specified signal via Bluetooth communication via the communication module, it may display a second code image corresponding to the next order of the first code image on the display. However, the code image corresponding to the next order is not limited to the second code image and may include other code images. According to another embodiment, when the processor receiving the specified signal displays the code image corresponding to the next order of the first code image in the specified area, the processor may not immediately display the code image corresponding to the next order, but may display a specified image (e.g., an advertisement image) for a specified time (e.g., 3s) and then display the code image corresponding to the next order. As another example, the processor may display the specified image for a specified time, and may cause a specified object (e.g., an image, text, and icon) to be included in a part of at least one code image among the plurality of code images to be displayed in the specified area.

According to another embodiment, the processor may display a code image corresponding to a next order of the first code image in the designated area based on information included in the first code image without receiving the designated signal from the external electronic device. The information included in the first code image may be information related to sync timing. The information related to the sync timing may be information related to an output order and time of each of the plurality of code images output through the designated area. The processor may output the first code image in the designated area for a designated time based on information included in the first code image (e.g., information related to sync timing), and then output the code image corresponding to a next order of the first code image for a designated time. For example, the processor may output the first code image through the designated area for 1 second. The processor may output the first code image for 1 second based on information included in the first code image (e.g., information related to sync timing), and then output the code image corresponding to a next order for 1.5 seconds. The above specified time may vary depending on the complexity of the information contained in each of the plurality of code images.

FIG. 4 is a drawing illustrating a method for providing a code image based on usage permission information for specific information according to one embodiment of the present invention.

Referring to FIG. 4, in operation 401, a processor (e.g., the processor (204) of FIG. 2) of an electronic device (e.g., the electronic device (200) of FIG. 2) may, if data is greater than or equal to a specified value, divide the data and generate a plurality of code images corresponding to the divided data. When dividing the data, the processor may divide the data based on at least one of the number, type (e.g., type), and size (capacity) of at least one piece of information included in the data. In the operation of generating the divided data into a plurality of code images, the processor may cause a code image corresponding to a first order among the plurality of code images to be displayed in a first order through a display (e.g., the display (201) of FIG. 2) to include information about the plurality of code images. The processor may display the code image corresponding to the first order in a specified area, which is at least a portion of the display.

According to one embodiment, when the specified value is 100 kb, the processor can divide the data having a size of 150 kb including image information and text information. When dividing the data, the processor can divide the data based on at least one of the number, type, and size of at least one piece of information included in the data. When the size of at least one piece of information included in the data is 10 kb, the processor can generate the data into 15 code images, each of which stores a size of 10 kb in one code image. According to another embodiment, when the type of at least one piece of information included in the data is set to image information, the processor can identify the image information included in the data, distinguish the image information and the text information, and generate a code image including the image information among the plurality of code images.

The above processor may cause the code images to be displayed in the designated area in the first order among the 15 generated code images to include information about the plurality of code images. The information about the plurality of code images may include information about the communication method, information about the plurality of code images, and information about usage rights for specific information.

In operation 403, the processor may receive a designated signal from an external electronic device. While the processor displays a code image corresponding to a first order containing information about the plurality of code images through the display, the external electronic device may scan a code image corresponding to a first order containing information about the plurality of code images.

The processor of the electronic device can receive the specified signal from the external electronic device that scanned the code image corresponding to the first order containing information about the plurality of code images, based on information about the communication method included in the information about the plurality of code images.

According to one embodiment, if the information about the communication method included in the information about the plurality of code images is information related to WiFi (Wifi-direction), the processor of the electronic device may form a WiFi communication channel with the processor of the electronic device based on the information about the communication method included in the information about the plurality of code images. The processor of the electronic device may receive the designated signal through the formed WiFi communication channel. The designated signal may be an ack signal, but is not limited thereto.

In operation 405, the processor may determine whether the external electronic device is a device capable of obtaining specific information based on a designated signal received from the external electronic device.

The processor may receive the specified signal from the external electronic device through a communication channel formed based on information about a communication method. The specified signal received by the processor may include information about the external electronic device. The information about the external electronic device may include at least one of address information of the external electronic device (e.g., a Mac address of the external electronic device) or information about a user using the external electronic device (e.g., an account of a user using the external electronic device). The information about the external electronic device may be obtained when the processor forms a communication channel with the external electronic device, and may be included in a specified signal obtained from the external electronic device.

The processor may determine, based on information about the external electronic device, whether the external electronic device is a device capable of identifying specific information (e.g., information requiring security) included in the plurality of code images.

According to one embodiment, the processor may set specific information of information about a plurality of code images included in a code image corresponding to the first order as designated information (e.g., dmsdngq). The processor may determine, based on address information of the external electronic device included in the received designated signal, whether an address of the external electronic device that transmitted the designated signal matches the designated information (e.g., dmsdngq). The designated information may be usage permission information for the specific information. According to another embodiment, when the specific information is set as designated information (e.g., samsung12) in relation to a user account, the processor may determine, based on information about a user included in the received designated signal, whether an account logged in to the external electronic device matches the designated information (e.g., samsung12). If the account logged in to the external electronic device matches the designated information, the processor may determine that the external electronic device is a device capable of identifying specific information included in the plurality of code images. Accordingly, the processor of the electronic device can determine whether the external electronic device is a device capable of obtaining specific information included in the plurality of code images based on the designated signal received from the external electronic device.

In operation 407, if it is determined that the external electronic device is a device capable of identifying specific information, the processor can display a code image corresponding to a next sequence of code images corresponding to the first sequence as a code image containing the specific information.

According to one embodiment, the processor may receive a designated signal from an external electronic device that scanned the first code image, if the designated information (e.g., dmsdngq) is set with respect to a specific information related to an address (Mac address) of the external electronic device. The designated information may be usage permission information for the specific information. The processor may determine whether the external electronic device is a device that can obtain the specific information included in the plurality of code images by checking whether the received designated signal matches the designated information related to the address of the external electronic device.

The processor of the electronic device, which determines that the external electronic device is a device capable of obtaining specific information, may display a code image that includes specific information while corresponding to the next order of code images displayed in a designated area of the display. According to another embodiment, when displaying a code image including the specific information on the display, a designated object may be included in a designated area of the code image including the specific information.

In operation 405, the processor may determine, based on the designated signal received from the external electronic device, that the external electronic device is a device that cannot obtain specific information. In operation 409, the processor of the electronic device that determines that the external electronic device is a device that cannot obtain specific information may display a code image corresponding to a next order of a code image corresponding to a first order in a designated area. At this time, the code image corresponding to the next order displayed in the designated area may include information excluding the specific information.

According to one embodiment, when the processor is set to designated information (e.g., samsung12) regarding specific information related to a user account, the processor may receive a designated signal from an external electronic device that scanned a first code image. The designated information may be usage permission information regarding the specific information. The processor may determine, based on information about a user included in the received designated signal, whether an account logged into the external electronic device matches the designated information. If the account logged into the external electronic device matches the designated information, the processor may determine that the external electronic device is a device that cannot identify specific information included in a plurality of code images.

The processor of the electronic device, which determines that the external electronic device is a device that cannot obtain specific information, can display a code image that is in the next order of the first code image and does not include the specific information in a designated area of the display.

As described above, according to various embodiments, the method for providing data includes, when the size of the data is greater than or equal to a specified value, an operation of dividing the data, an operation of generating a plurality of code images corresponding to each of the divided data, an operation of specifying a display order of the generated plurality of code images, an operation of displaying a code image whose display order corresponds to a first order among the plurality of code images, in a specified area of a display (e.g., a display device (160) of FIG. 1 or a display (201) of FIG. 2), and an operation of receiving a specified signal from an external electronic device (e.g., an electronic device (102 or 104) of FIG. 1) through a communication module (e.g., a communication module (190) of FIG. 1 or a communication module (202) of FIG. 2)) or, based on information included in the code image whose display order corresponds to a next order among the plurality of code images, in the specified area, and the code image whose display order corresponds to a first order among the plurality of code images may include information in the plurality of code images.

According to various embodiments, the information about the plurality of code images may include at least one of information about usage rights for specific information included in the data and information about a communication method for transmitting and receiving the specified signal.

According to various embodiments, the usage permission information for the specific information may include at least one of identification information of the external electronic device capable of obtaining the specific information or identification information of the user.

According to various embodiments, the information about the plurality of code images may further include authentication information about specific information included in the data, and the authentication information about the specific information may include information that authenticates that the external electronic device is a device capable of obtaining the specific information included in the plurality of code images.

According to various embodiments, the operation of displaying, in the designated area, a code image whose display order corresponds to the following order among the plurality of code images may further include an operation of determining, based on information about the external electronic device included in the received designated signal, whether the external electronic device is a device capable of identifying specific information included in the plurality of code images.

According to various embodiments, the information about the external electronic device may include at least one of address information about a device capable of obtaining the specific information and information about a user account capable of obtaining the specific information.

According to various embodiments, the operation of dividing the data may include an operation of dividing the data based on at least one of the number of information included in the data, the type of information, and the size of the information.

According to various embodiments, the method may include an operation of specifying a display order for the plurality of code images to be displayed in the designated area based on a priority for information included in each of the divided data.

According to various embodiments, when receiving a specified signal from the external electronic device, the operation of displaying the plurality of code images in the specified area may further include an operation of displaying a specified image in the specified area in response to receiving the specified signal, and an operation of displaying a code image corresponding to the next order after a specified time has elapsed after the specified image is displayed.

According to various embodiments, when receiving a specified signal from the external electronic device, the operation of displaying the plurality of code images in the specified area may further include an operation of sequentially displaying code images including information excluding the specific information in the specified area in the display order when determining, based on the specified signal, that the external electronic device is a device that cannot identify the specific information.

Referring to FIG. 5, in state 501, a processor (e.g., the processor (204) of FIG. 2) of an electronic device (500) (e.g., the electronic device (200) of FIG. 2) may display a code image (510) corresponding to a first order among a plurality of code images in a designated area through a display (e.g., the display (201) of FIG. 2) of the electronic device (500). When the size of data is greater than or equal to the designated value, the processor of the electronic device (500) may divide the data and generate a plurality of code images corresponding to the divided data. The processor may display a code image (e.g., a code image corresponding to the first order) to be displayed in a first order in the designated area of the display among the plurality of code images. While the processor displays the code image (510) corresponding to the first order in the designated area, an external electronic device may scan the code image to be displayed in the first order. The processor may receive a specified signal from the external electronic device that scanned the code image (510) corresponding to the first order. The processor may determine whether the electronic device is a device capable of obtaining specific information based on information about the external electronic device included in the specified signal.

According to one embodiment, when the specified value is 10 kb and the size of data to be generated as a code image is 120 kb, the processor may divide the data having a size of 120 kb and generate a plurality of code images corresponding to the divided data. When the processor generates the data into the plurality of code images, the processor may divide the data based on at least one of the number, type (e.g., type), and size (e.g., capacity) of at least one piece of information included in the data. The processor may generate the 120 kb data into 12 code images that may include 10 kb of data based on the size of at least one piece of information included in the data. The processor may display a first code image (e.g., a code image (510) corresponding to the first order of FIG. 5) to be displayed in an area designated in a first order among the generated 12 code images.

While the processor displays the first code image in the designated area, an external electronic device can scan the first code image (510) being displayed in the designated area.

The electronic device (500) can receive a first designated signal from the external electronic device through a communication channel formed based on information about a communication method included in the first code image.

In states 503, 505 and 507, when the processor of the electronic device (500) receives a designated signal from the external electronic device, it can display a code image (520) corresponding to the next order of the code image (510) corresponding to the first order being displayed in the designated area. Thereafter, whenever the processor displaying the next code image (520) receives a designated signal from the external electronic device, it can display the code image (520) currently being displayed in the designated area as code images (530 and 540) corresponding to the next order.

According to one embodiment, the processor, which receives the first designated signal from the external electronic device, may display the first code image displayed in the designated area as a second code image (e.g., code image 520 of FIG. 5) corresponding to the next sequence.

When the processor of the electronic device (500) receives a second designated signal from the external electronic device, the second code image (520) displayed in the designated area of the display may be displayed as a third code image (530) corresponding to the next order. In addition, in state 507, when the processor of the electronic device (500) receives a third designated signal from the external electronic device, the third code image (530) displayed in the designated area of the display may be displayed as a fourth code image (540). According to another embodiment, when the processor receives a designated signal from the external electronic device, instead of changing the code image currently displayed in the designated area to the code image corresponding to the next order, a designated image (e.g., an advertisement image) may be displayed for a designated period of time, and then the code image corresponding to the next order may be displayed.

FIG. 6 is a drawing explaining a method for displaying a code image based on a received signal according to one embodiment of the present invention.

Referring to FIG. 6, a processor (e.g., a processor (204) of FIG. 2) of an electronic device (e.g., an electronic device (200) of FIG. 2) may divide the data if the size of the data is greater than or equal to a specified value. The processor may generate a plurality of code images corresponding to the divided data. When the processor divides the data, the data may be divided based on at least one of information about the number of pieces of information included in the data, information about the type, and information about the size of the data.

In state 610, the processor of the electronic device may divide the data and generate a plurality of code images (611, 613, 615, 617, and 619) corresponding to the divided data. When generating the plurality of code images, the processor may distinguish and generate code images (613 and 617) including specific information requiring security from among the plurality of code images and code images (615 and 619) including information excluding the specific information. The processor may store information on a plurality of code images including usage permission information and information on a communication method for the specific information in a code image (611) (e.g., a code image corresponding to the first order) to be displayed first in the designated area among the generated plurality of code images (611, 613, 615, 617, and 619). The processor of the electronic device can display a code image (611) corresponding to the first order among the plurality of generated code images in a designated area of a display (e.g., the display (201) of FIG. 2).

According to one embodiment, the processor can segment the data based on at least one of the number, type, and size of at least one piece of information included in the data.

The above processor may, when the data includes five pieces of information, store one piece of information in one code image based on the number of at least one piece of information included in the data, thereby generating a total of five code images (e.g., code images corresponding to 611, 613, 615, 617, and 619 of FIG. 6). When generating the five code images, the processor may distinguish and generate code images including specific information (e.g., code images corresponding to 613 and 617 of FIG. 6) and code images including information excluding specific information (e.g., code images corresponding to 615 and 619 of FIG. 6).

The processor of the electronic device may display a first code image (e.g., code image (611) of FIG. 6) to be displayed in a first order in a designated area of the display among the plurality of code images, on a designated area of a display (e.g., display (201) of FIG. 2) included in the electronic device. While the processor displays the first code image through the display in the designated area, an external electronic device may scan the first code image. The processor may receive a first designated signal from the external electronic device that scanned the first code image. The first designated signal may include information about the external electronic device (e.g., address information of the external electronic device or information about a user).

In state 630, the processor of the electronic device can receive a specified signal from the external electronic device that scanned the code image (631) corresponding to the first order (e.g., the code image (611) of FIG. 6). The specified signal can be transmitted by the external electronic device based on information about a plurality of code images included in the code image corresponding to the first order. The information about the plurality of code images can include information about a communication method. Accordingly, the external electronic device that scanned the code image corresponding to the first order can request the electronic device to form a communication channel based on the information about the communication method. The electronic device can receive a specified signal from the external electronic device through the communication channel formed based on the request. The processor can determine, based on the received specified signal, whether the external electronic device is a device that can obtain code images (633 and 637) including specific information (e.g., code images (613 and 617) of FIG. 6). The above-mentioned designated signal contains information about the electronic device, so that the processor of the electronic device can determine whether the external electronic device that transmitted the above-mentioned designated signal is a device capable of obtaining a code image containing specific information.

When the processor of the electronic device determines that the external electronic device is a device capable of obtaining specific information, the processor may sequentially display, in the designated area, code images (633 and 637) including the specific information and code images (635 and 639) including information excluding the specific information among the plurality of code images (e.g., code images (615 and 619) of FIG. 6).

According to one embodiment, if specific information included in the first code image (e.g., the code image corresponding to 631 of FIG. 6) is set as designated information (e.g., 14235463) related to an address (e.g., Mac address) of an external electronic device, the processor may identify, based on a first designated signal received from the external electronic device that scanned the first code image, whether the external electronic device is a device capable of obtaining the specific information. The designated information may be usage permission information for the specific information. The processor may determine, based on the designated information about the external electronic device included in the designated signal, whether the address (e.g., Mac address of the external electronic device) of the external electronic device matches. If the designated information related to the address of the external electronic device matches the address of the external electronic device, the processor may identify that the external electronic device is a device capable of obtaining the specific information. Additionally, when the processor receives the first designated signal from the external electronic device, the processor may form a communication channel with the external electronic device based on information about the communication method included in the first code image (e.g., when set to Bluetooth). The processor may receive the first designated signal through the formed communication channel.

A processor of the electronic device that has identified that the external electronic device is a device capable of obtaining specific information can display a second code image (e.g., code image 633 of FIG. 6) including specific information in a subsequent order of a first code image corresponding to a first order displayed in a designated area of the display. While the processor is displaying the second code image, if a second designated signal is received from the external electronic device that scanned the second code image through a Bluetooth communication channel, a third code image (e.g., code image 635 of FIG. 6) corresponding to a subsequent order of the second code image can be displayed in the designated area.

Thereafter, when the processor displaying the third code image receives a third designated signal from the external electronic device through a Bluetooth communication channel, a fourth code image (e.g., code image 637 of FIG. 6) including specific information may be displayed in the designated area. Additionally, when the processor displaying the fourth code image in the designated area receives a fourth designated signal from the external electronic device, a fifth code image (e.g., code image 639 of FIG. 6) may be displayed in the designated area. In another embodiment, when the processor of the electronic device receives a designated signal from the external electronic device, it may not display a code image corresponding to the next sequence, but may display designated data (e.g., an advertisement image) for a predetermined period of time.

On the other hand, if the processor of the electronic device in the state 650 identifies that the external electronic device is a device that cannot obtain a code image including specific information (e.g., code images (613 and 617) of FIG. 6), the code image (655) (e.g., code image (615) of FIG. 6) that does not include specific information may be displayed in the next order after the first code image (651) (e.g., code image (611) of FIG. 6) corresponding to the first order displayed in the designated area. Since the processor determines that the external electronic device is a device that cannot obtain specific information, the code images (655 and 659) that include information excluding the specific information may be displayed in the designated area without displaying the code images including the specific information (e.g., code images (613 and 617) of FIG. 6).

According to one embodiment, if specific information included in the first code image (651) corresponding to the first order (e.g., the code image corresponding to 611 of FIG. 6) is set as information designated in relation to a user account (e.g., samsung12), the processor may identify whether an account logged into the external electronic device is an account that can obtain specific information based on information about the user included in the first designated signal received from the external electronic device.

If an account logged into the external electronic device that transmitted the first designated signal is an account that does not match the designated information, the processor of the electronic device may determine that the external electronic device is a device that cannot obtain code images including the specific information. When the processor determines that the external electronic device is a device that cannot obtain code images including the specific information, if it receives a first designated signal from the external electronic device that scanned the first code image (e.g., code image (611) of FIG. 6) corresponding to the first order, it may display a code image (e.g., code image (615) of FIG. 6) including information excluding the specific information as a second code image in the designated area. If the processor receives a second designated signal from the external electronic device through a Bluetooth communication channel, it may display a code image (e.g., code image (619) of FIG. 6) including information excluding the specific information as a third code image that is a next order of the second code image.

FIG. 7 is a drawing illustrating another method for displaying a code image based on a received signal according to one embodiment of the present invention.

Referring to FIG. 7, a processor (e.g., a processor (204) of FIG. 2) of an electronic device (e.g., an electronic device (200) of FIG. 2) may divide the data if the size of the data is greater than or equal to a specified value. The processor may generate a plurality of code images corresponding to the divided data. When the processor divides the data, the data may be divided based on at least one of information about the number of pieces of information included in the data, information about the type, and information about the size.

In state 710, the processor of the electronic device may divide data and generate a plurality of code images (711, 713, 713', 715, 717, 717', and 719) corresponding to the divided data. When generating the plurality of code images, the processor may generate code images (713 and 717) including specific information requiring security among the plurality of code images (711, 713, 713', 715, 717, 717', and 719). However, when generating the code images (713 and 717) including the specific information, the processor may separately generate code images (713' and 717') corresponding to the order of the code images including the specific information, but including default information instead of the specific information.

The above processor may store information about a plurality of code images including usage permission information and communication method information about the specific information in a code image (e.g., a code image corresponding to the first order) to be displayed first in the designated area among the plurality of generated code images (711, 713, 713', 715, 717, 717' and 719). The processor of the electronic device may display a code image (711) corresponding to the first order among the plurality of generated code images (711, 713, 713', 715, 717, 717' and 719) in a designated area of a display (e.g., a display (201) of FIG. 2).

According to one embodiment, the processor can segment the data based on at least one of the number, type, and size of at least one piece of information included in the data.

The processor may, when the data includes five pieces of information, store one piece of information in one code image based on the number of at least one piece of information included in the data, thereby generating a total of five code images (e.g., code images corresponding to 711, 713, 715, 717, and 719 of FIG. 7). When generating the five code images, the processor may distinguish and generate code images including specific information (e.g., code images corresponding to 713 and 717 of FIG. 7) and code images including information excluding the specific information (e.g., code images corresponding to 715 and 719 of FIG. 7). In addition, the processor may generate code images corresponding to the order of code images including the specific information but including default information excluding the specific information (e.g., code images corresponding to 713' and 717' of FIG. 7), thereby generating a total of seven code images.

The processor of the electronic device may display a first code image (e.g., code image (711) of FIG. 7) to be displayed in a first order in a designated area of the display among the plurality of code images, on a designated area of a display (e.g., display (202) of FIG. 2) included in the electronic device. While the processor displays the first code image through the display in the designated area, an external electronic device may scan the first code image. The processor may receive a first designated signal from the external electronic device. The first designated signal may include information about the external electronic device (e.g., address information of the external electronic device or information about a user account).

In state 730, the processor of the electronic device can receive a specified signal from the external electronic device that scanned the code image (731) corresponding to the first order (e.g., the code image (711) of FIG. 7). Based on the received specified signal, the processor can determine whether the external electronic device is a device capable of obtaining code images (733 and 737) including specific information (e.g., the code images (713 and 717) of FIG. 7).

When the processor of the electronic device determines that the external electronic device is a device capable of obtaining specific information, the processor may sequentially display, in the designated area, code images (733 and 737) including the specific information and code images (735 and 739) including information excluding the specific information among the plurality of code images (e.g., code images (715 and 719) of FIG. 7).

According to one embodiment, if the usage permission information for specific information included in the first code image corresponding to the first order (e.g., the code image corresponding to 731 of FIG. 7) is set to specified information (e.g., 14235463) related to an address (e.g., Mac address) of an external electronic device, the processor may identify whether the external electronic device is a device capable of obtaining specific information based on a first specified signal received from the external electronic device that scanned the first code image. If the address of the external electronic device included in the specified signal (e.g., the Mac address of the external electronic device) matches the specified information, the processor may identify that the external electronic device is a device capable of obtaining specific information. In addition, when the processor receives the first specified signal from the external electronic device, the processor may receive the first specified signal through a communication channel formed based on information on a communication method included in the first code image (e.g., when set to Wi-Fi).

A processor of the electronic device that has identified that the external electronic device is a device capable of obtaining specific information may display a second code image (e.g., code image 733 of FIG. 7) including specific information in a subsequent order of a first code image corresponding to a first order displayed in a designated area of the display. While the processor is displaying the second code image, if a second designated signal is received from the external electronic device that scanned the second code image through a Wi-Fi communication channel, a third code image (e.g., code image 735 of FIG. 7) corresponding to a subsequent order of the second code image may be displayed in the designated area.

Thereafter, when the processor displaying the third code image receives a third designated signal from the external electronic device through a Wi-Fi communication channel, a fourth code image (e.g., code image 737 of FIG. 7) including specific information in the designated area can be displayed. Additionally, when the processor displaying the fourth code image in the designated area receives a fourth designated signal from the external electronic device, a fifth code image (e.g., code image 739 of FIG. 7) can be displayed in the designated area.

On the other hand, in the state 750, the processor of the electronic device may identify that the external electronic device is a device that cannot obtain a code image including specific information (e.g., code images (713 and 717) of FIG. 7). The processor may display a code image (755) (e.g., code image (715) of FIG. 7) that corresponds to the order of code images including specific information (e.g., code images (713 and 717) of FIG. 7) in the next order of a first code image (751) corresponding to the first order displayed in the designated area, but includes default information rather than the specific information.

Since the above processor determines that the external electronic device is a device that cannot obtain specific information, the processor can display code images including default information corresponding to the order in which code images including specific information are displayed in the designated area.

According to one embodiment, if the usage permission information for specific information included in the first code image (751) corresponding to the first order (e.g., the code image corresponding to 711 of FIG. 7) is set to information specified in relation to a user account (e.g., samsung12), the processor may determine which account is logged into the external electronic device based on the information about the user included in the first specified signal received from the external electronic device.

If an account logged into the external electronic device does not match the specified information, the processor of the electronic device may determine that the external electronic device is a device that cannot obtain code images including the specific information. When the processor determines that the external electronic device is a device that cannot obtain code images including the specific information, if it receives a first specified signal from the external electronic device that scanned the first code image (e.g., code image (711) of FIG. 7) corresponding to the first order, it may display a code image (753') (e.g., code image (713') of FIG. 7) including default information, not a code image (753) including the specific information (e.g., code image (715) of FIG. 7), as a second code image in the specified area. If the processor receives a second specified signal from the external electronic device through a Wi-Fi communication channel, it may display a code image (755) (e.g., code image (715) of FIG. 7) including information excluding the specific information as a third code image following the second code image.

Thereafter, when the processor receives a third designated signal from the external electronic device, the code image (755) including information excluding specific information, which is a third code image displayed in the designated area, can be displayed as a code image (757') including default information as a fourth code image (e.g., code image (717') of FIG. 7). Additionally, when the processor of the electronic device receives a fourth designated signal from the external electronic device, the code image (757') including default information, which is displayed as the fourth code image in the designated area, can be displayed as a code image (759) including information excluding specific information, which is a fifth code image (e.g., code image (719) of FIG. 7), in the designated area.
