Description

Signature Data and Signature Track Transmission System

The present invention relates to a signature data transmission system, and more particularly to a signature data transmission system using a transparent touch display panel.

In addition to telegraphic transfer, importers can apply to banks for letters of credit for international trade. Exporters can apply to the franking bank for franking with documents that meet the letter of credit conditions. Regardless of whether the shipping company provides the original bill of lading to the exporter, the exporter provides it to the franking bank, or mails the documents to the issuing bank, if the documents fall into the hands of others during the transportation process, there may be a risk that a third party will pick up the goods with the bill of lading.

In view of the above, the present invention provides a signature data transmission system.

According to an embodiment of the present invention, a signature data transmission system includes a sending device, a receiving device and a server, wherein the sending device includes a first transparent touch display panel, a marking component and a first microcontroller, and the receiving device includes a second transparent touch display panel, a scanning component and a second microcontroller.

Moreover, according to the contents disclosed in this specification, the scope of the patent application and the drawings, any person skilled in the relevant art can easily understand the relevant purposes and advantages of the present invention. The following embodiments are to further illustrate the viewpoints of the present invention, but are not to limit the scope of the present invention by any viewpoint.

Please refer to FIG. 1, which is a block diagram of a signature data transmission system according to an embodiment of the present invention. As shown in FIG. 1, the signature data transmission system includes a sending device 11 for digital signature, a receiving device 12 for digital verification, an optical pen 15 optionally configured, and a server 19 connected to the sending device 11 and the receiving device 12. The sending device 11 includes a first transparent touch display panel 110, a first microcontroller 112, and a marking component 114. The first transparent touch display panel 110 is used to cover the first document 2 to be signed, and can receive an input track corresponding to the first document 2 and can be controlled by a first control signal to display a display track 4 related to the input track, for example, displayed on the first display area 1101 as shown in FIG. 1. It should be particularly noted that the first display area 1101 of FIG. 1 merely shows the position of the touch input and display by way of example. The touch input and display can be at any position of the first transparent touch display panel 110, and the present invention is not limited thereto. The first microcontroller 112 is connected to the first transparent touch display panel 110 and the marking component 114, and is used to generate a first control signal and a second control signal according to the input track, thereby respectively controlling the first transparent touch display panel 110 and the marking component 114. The marking component 114 can be controlled by the second control signal to mark the first pattern 25 on the first document 2. The receiving device 12 includes a second transparent touch display panel 120, a second microcontroller 122 and a scanning component 124, wherein the second transparent touch display panel 120 is used to cover the second document 3 to be checked, and the scanning component 124 can be triggered (for example, the user presses a button) to scan the second pattern 35 on the second document 3, and the second microcontroller 122 receives the verification data from the server 19 to determine whether the second pattern 35 is the same as the first pattern 25. If so, the second microcontroller 122 transmits a third control signal to the second transparent touch display panel 120, so that the second transparent touch display panel 120 can display the display track 4 in the second display area 1201.

In this example, the first transparent touch display panel 110 may be an electronic paper, or an optical panel that can be placed on the first document 2 without obstructing the line of sight to simultaneously present the document content and the digital signature. This part belongs to a known technology and will not be elaborated here.

The optical pen 15 of this example can be connected to the first transparent touch display panel 110 via Bluetooth or other wireless communication methods (such as WiFi or ZigBee) to generate an input track of the signing process. In other embodiments, the optical pen 15 can be omitted and a touch operation can be performed by hand or other devices with touch functions to input the input track to the first transparent touch display panel 110, but the present invention is not limited thereto.

The marking component 114 in this example can be a micro inkjet printer or a micro laser engraving machine or other device capable of generating patterns on a document. The generated first pattern 25 can be a recognizable QR code or barcode, etc., so that the same first document 2 can have a different first pattern 25 each time it is signed.

In this example, the server 19 can be connected to the sending device 11 and the receiving device 12 via wireless communication technology. The scanning component 124 can obtain information of the second pattern 35 of the second document 3 via a laser scanning device. The signature data transmission system architecture of the embodiment of this case has been described so far, and the operation flow of the system is further described below.

Please refer to FIG. 2a and FIG. 2b in conjunction with the system of FIG. 1 . FIG. 2a and FIG. 2b are operation flow charts of two parts of a signature data transmission system according to an embodiment of the present invention. As shown in FIG. 2a, the operation process of the signature data transmission system includes step S100: the first transparent touch display panel 110 can receive the input track of the signature and generate a sensing signal according to the input track and transmit it to the first microcontroller 112; step S101: the first microcontroller 112 can receive the sensing signal from the first transparent touch display panel 110 and generate a first control signal corresponding to the sensing signal to transmit the first control signal to the first transparent touch display panel 110, wherein the first control signal includes information of the input track; step S102: the first transparent touch display panel 110 can be controlled by the first control signal to display a display track 4 on the first display area, wherein the display track Trace 4 is a copy trace based on the input trace. Step S103: After the first microcontroller 112 receives the sensing signal, a second control signal can be generated and transmitted to the marking component 114, wherein the second control signal includes data of a first pattern, and the data of the first pattern is independent of the sensing signal. Specifically, when the first transparent display panel 11 receives two identical or similar signature traces, two identical or similar sensing signals will be generated, but the data of the corresponding first patterns may be completely different, so that the two marked first patterns are also different and the two signatures are distinguished. Step S104: The marking component 114 can be controlled by the second control signal to mark the first pattern 25 on the first document 2. It should be noted that step S101 and step S102 can be continuous steps, step S103 and step S104 can be continuous steps, and the first control signal used to control the first transparent touch display panel 110 to display a display track 4 and the second control signal used to control the marking component 114 to mark the first pattern 25 do not have an absolute time sequence relationship. Therefore, step S101, step S102 and step S103, step S104 can also be parallel in timing or one of them can precede the other. For example, step S103, step S104, step S101 and step S102 can be performed in sequence, but the present case is not limited to this.

After the sending device 11 completes the above operations, the first microcontroller 112 further transmits the first control signal and the second control signal to the server 19. Then, in step S105: the server 19 connected to the sending device 11 and the receiving device 12 receives the second control signal including the first pattern 25 data, and generates verification data including the first pattern 25 data, so as to transmit the verification data to the second microcontroller 122, wherein the second control signal is further used to control the server 19 to transmit the verification data. In addition, step S105 further includes: the server 19 receives the first control signal including the input track data, and generates a third control signal having the input track information and transmits it to the second microcontroller 122, wherein the third control signal is used to control the second transparent display panel to display the above-mentioned display track 4 according to the input track information in the subsequent step.

The following steps are performed by the receiving device 12. Please refer to FIG. 2b, including step S106: the scanning component 124 can be triggered (for example, the user presses a button) to scan the second pattern 35 on the second document 3, and transmit the data of the second pattern 35 to the second microcontroller 122, step S107: the second microcontroller 122 that receives the data of the first pattern 25 and the second pattern 35 determines whether the second pattern 35 is the same as the first pattern 25, if not, then proceeds to step S108: the second microcontroller 122 does not act, so-called inaction, It means that the microcontroller does not actively send a control signal to other devices, so the receiving device 12 can be in a standby state, and when the scanning component 124 is triggered again, it scans a pattern on another document and determines whether the pattern is the same as the first pattern 25; if so, step S109 is performed: the second microcontroller 122 transmits the third control signal to the second transparent touch display panel 120, and step S110: the second transparent touch display panel 120 displays the display track 4 according to the third control signal. Through the verification mechanism for the first pattern 25 and the second pattern 35 of this embodiment, it can be ensured that the verifier without a legitimate document cannot obtain the corresponding second pattern 35 and enter step S108, that is, cannot obtain the display track 4 with signature information, where the legitimate document is a document with a pattern identical to the first pattern.

For the above embodiment, there may be other embodiments including additional steps. For example, in one embodiment, when the second microcontroller 122 determines that the second pattern 35 is the same as the first pattern 25, it requests the server 19 for data corresponding to the display track 4, and generates a third control signal according to the data corresponding to the display track 4 to control the second transparent touch display panel 120 to display the display track 4. In other words, although the above embodiment The third control signal of the embodiment is generated by the server, but it can also be generated by the second microcontroller, as long as the third control signal is based on the same data and is used for a similar function (displaying the display track on the second transparent display panel), the case is not limited to this; or in another embodiment, the server 19 is further used to obtain data corresponding to the display track 4 from the sending device 11, wherein the verification data further includes the display track 4.

Please refer to FIG. 3, which is a block diagram of a signature data transmission system according to another embodiment of the present invention. As shown in FIG. 3, this embodiment covers all the components shown in FIG. 1, and the signature data transmission system includes a sending device 11, a receiving device 12, an optical pen 15, and a server 19. The sending device 11 includes a first transparent touch display panel 110, a first microcontroller 112, and a marking component 114 for marking a first pattern 25 on a first document 2, and the receiving device 12 includes a second transparent touch display panel 120, a second microcontroller 122, and a scanning component 124 for scanning a second pattern 35 on a second document 3. The connection and signal transmission relationship of the above components are the same as those shown in FIG. 1 and FIG. 2, so repeated description is omitted here. In addition, the receiving device 12 in this example further includes a lens 126 connected to the second microcontroller 122 for being triggered (such as a button) to obtain the user (or verifier) image and transmit it to the second microcontroller 122.

Please refer to FIG4 in conjunction with FIG3, which is an operation flow chart of the signature data transmission system according to the embodiment of FIG3. In the operation flow of the signature data transmission system, before step S205, steps S100 to S104 (not shown) repeated in FIG2a are included. The operation process also includes step S205: the server 19 obtains a legitimate personnel data corresponding to the first file 2 according to the first control signal and the second control signal, and sends the verification data and the legitimate personnel data to the second microcontroller 122. For example, the server 19 can obtain the identity data of a signer from the cloud database through the input track in the first control signal, and list the possible cooperation objects, and then lock the specific cooperation object through the first pattern data in the second control signal to generate the legitimate personnel data, step S206: the scanning component 124 is triggered to scan the second pattern 35 on the second file 3, step S207: the second microcontroller 122 determines whether the second pattern 35 is the same as the first pattern 25, if not, Then execute step S208: the second microcontroller 122 does not operate; if so, execute step S209: the lens 126 is triggered to obtain the user image, step S210: the second microcontroller 122 determines whether the user image conforms to the legal member information, if not, execute step S211: the second microcontroller 122 controls the second transparent touch display panel 120 to display a non-transparent full-screen image so that the user cannot see the display track 4; if so, execute step S212 which is the same as step S109: the second microcontroller 122 transmits the third control signal to the second transparent touch display panel 120, and step S213 which is the same as step S110: the second transparent touch display panel 120 displays the display track 4.

In addition, taking the operation flow of Figure 4 as an example, step S208 and step S211 can also be interchanged so that the user can achieve the effect of not being able to obtain the display track smoothly. For example, if the second microcontroller determines that the second pattern is different from the first pattern, the second microcontroller can control the second transparent touch display panel to display a non-transparent screen, or if the second microcontroller determines that the user image does not match the legal member information, the second microcontroller can be made inactive. The identity of the user can be further verified through the method of Figure 4. It should be noted that the two judgments (step S207 and step S210) performed by the second microcontroller 122 in Figure 4 do not have an absolute timing relationship, which will be described later.

Please refer to FIG. 5 in conjunction with FIG. 3. FIG. 5 is another operation flow chart of the signature data transmission system according to the embodiment of FIG. 3. In FIG. 5, the operation flow of the signature data transmission system omits steps S100 to S104 which are repeated in FIG. 2, and includes step S205: the server generates and transmits verification data and legal personnel data to the second microcontroller, step S209: the camera is triggered to obtain the user image, step S210: the second microcontroller 122 determines whether the user image matches the legal member data, if not, then executes step S311: the second microcontroller 122 does not turn on the scanning function of the scanning component 124, wherein the scanning function It can be used to scan the pattern on the document. If yes, then execute step S206: the scanning component is triggered to scan the second pattern on the second document, step S207: the second microcontroller determines whether the second pattern is the same as the first pattern (if not, execute step S208 in which the second microcontroller does not act, if yes, execute step S212 in which the second microcontroller transmits the third control signal to the second transparent touch display panel), and step S213 after step S212: the second transparent touch display panel displays the display track. The scanning function defined in step S311 is that the scanning component 124 scans the second pattern 35 of the second document 3. In FIG. 5 , except for step S311, the other steps are different from the steps in FIG. 4 mainly in the order of operation, so the detailed description of each repeated step is omitted here.

Please refer to FIG. 6 in conjunction with FIG. 3. FIG. 6 is another operation flow chart of the signature data transmission system according to the embodiment of FIG. 3. In FIG. 6, the operation flow of the signature data transmission system omits steps S100 to S104 which are repeated in FIG. 2, and includes step S205: the server generates and transmits verification data and legal personnel data to the second microcontroller, step S209: the camera is triggered to obtain the user image, step S210: the second microcontroller 122 determines whether the user image is consistent with the legal member data, if not, then executes step S411: the second microcontroller 122 does not determine whether the second pattern 35 is the same as the first pattern 25. Specifically, this step can be controlled by the scanning component not to scan. After the scanning component scans and obtains the second pattern, the second microcontroller does not accept the second pattern, or accepts it but does not make further judgment to achieve this. If so, step S206 is executed: the scanning component is triggered to scan the second pattern on the second document, step S207: the second microcontroller determines whether the second pattern is the same as the first pattern (if not, step S208 is executed in which the second microcontroller does not act, if yes, step S212 is executed in which the second microcontroller transmits the third control signal to the second transparent touch display panel), and step S213: the second transparent touch display panel displays the display track.

Through the operation flow of FIG. 4 to FIG. 6, it can be found that the step S206 of scanning the second pattern and the step S209 of photographing the user's image can be interchanged in terms of timing, so that the judgment step S207 and the step S210 can also be interchanged or performed in parallel in terms of timing. Therefore, the operation flow of the signature data transmission system provided in this article is an explanation that is easy to understand, and the simple replacement or change of the steps should not deviate from the scope of this case.

Please refer to FIG. 7, which is a three-dimensional structural diagram of a sending device of a signature data transmission system according to another embodiment of the present invention. In the sending device 11' of this example, it further includes a plate body 116 pivotally connected to the first transparent touch display panel 110, which can form a sandwich layer 118 with the first transparent touch display panel 110 for placing the first document 2 to perform the above-mentioned operation process. In addition, the structure of the plate body 116 can also be applied to the second transparent touch display panel. In other embodiments, the plate body 116 can be the first and/or second transparent touch display panel, and can also include a marking component and/or a scanning component to mark and/or scan the back of the document.

With the above structure, the signature data transmission system disclosed in this case allows the signer to use the first transparent touch display panel to digitally sign a document and then store the signature trace in the server, and generate a physical pattern on the document for subsequent confirmation, so that when the proofreader obtains the document with the pattern, he can scan and verify the pattern through the second transparent touch display panel. Once confirmed to be correct, the signature trace will be displayed on the second transparent touch display panel for the proofreader to confirm. In addition, the signature data transmission system of this case can be used in conjunction with an optical pen, or/and a lens can be provided on the receiving device to capture the proofreader's image to confirm whether he/she is a legitimate person. The disclosed signature data transmission system can effectively enhance the confidentiality of paper documents and prevent the risk of traditional written signatures being abused by malicious persons or being used by third parties to collect goods through bills of lading.
