Description

Method, system and computer readable recording medium for processing fine data code based on image information

The present invention relates to a method, system, and computer readable recording medium for processing fine data codes based on image information. More particularly, it relates to a method, system, and computer readable recording medium capable of generating fine data codes by encoding image information and confirming image information by utilizing the same.

Today, barcodes, which are used to digitize and conveniently provide information such as various products offline, are a representative use case of data codes. Such a barcode means a code made of a bar, and is a code composed of a combination of black and white bars having different thicknesses so that a computer can read them optically.

At this time, barcodes can optically read information such as letters, numbers, and symbols through a combination of black bars having different thicknesses and white bars between them. That is, information can be extracted through the process of detecting the amount of reflected light by irradiating light onto the barcode. The black bar of the barcode reflects a small amount of light, while the white space part of the barcode reflects a small amount of light. Since it reflects a large amount of light, it can be read by a computer by converting it into bits of 0 and 1, which are electrical signals, depending on the degree of light reflected from the barcode. Therefore, barcodes are widely used in various fields because data input is easy and configuration of a reading system is easy.

However, since the information contained in the conventional barcode is exposed as it is so that anyone can visually see it, it is bound to be limited in its use in information where security is important. Therefore, it is difficult to use barcodes when both an individual's photo and personal information are included, such as an application form and an identification card.

Specifically, a barcode may be attached to the ID photo to verify the information of the ID photo, but in this case, there is a risk that an individual's portrait right and personal information may be exposed to the outside at the same time. In particular, certain parts of the ID photo There is also a problem that the barcode can be covered, providing a dirty feeling aesthetically.

As a result, whether the ID photo (or half name card, passport photo) submitted for issuance/reissuance of an identification card such as a driver's license, resident registration card, or passport is a photo taken within 6 months according to the regulations, and the standard size [2.5×3, 3 × 4, 3.5 × 4.5 (Cm)] is unreliable and time-consuming because it must rely solely on the visual examination of the person in charge of issuance.

In addition, there is no alternative other than the visual judgment of the person in charge as a way to verify this even if only the photo portion is forged or altered on the application form or the ID card. In particular, at the test site where identity verification is required for a short period of time for a large number of people, whether the ID photo on the application form of the candidate taking the test is a photo taken within 3 months according to the regulations, and whether the ID photo on the application form and the actual test taker There is a realistic limit in that it is virtually impossible to accurately determine whether or not it is the same person with the naked eye.

Referring to FIG. 3, an interface screen for 'registering image information' is displayed. First, '1. You can enter the date the ID photo was taken through the ‘Date taken’ item. In this case, a calendar mode may be supported as shown for the user's convenience.

Next, ‘2. You can enter the information of the person who has the legitimate portrait right for the ID photo in the 'person with portrait right' item. In addition to the basic name, personal information such as mobile phone number and date of birth may be added, which is separately performed to provide image information. This information is necessary for self-authentication during the authentication process.

Next, ‘3. In the 'photographer' item, the name of the person who took the ID photo can be entered, and information about the company such as the company registration number can be additionally added.

Next, ‘4. In the 'Use of Image' item, you can enter the purpose for which the ID photo will be used, and it is also possible to implement it so that it can be selected from a pre-determined list.

Next, ‘5. In the ‘validity period’ item, the validity period of the ID photo can be entered, and the validity period can be automatically entered when the shooting date and purpose of the image are entered. For example, if the purpose of the ID photo is for taking a test, 3 months according to the relevant regulations, and if it is for issuing/reissuing an identification card such as a driver's license, resident registration card, passport, etc., the validity period of 6 months will be automatically entered according to the relevant regulations. may be

Next, ‘6. In the ‘original image’ item, the corresponding ID photo can store the original image, which is for future comparison and verification of the printed ID photo and the original image. At this time, the standard size [2.5 × 3, 3 × 4, 3.5 × 4.5 (Cm)] information of the corresponding ID photo (or half name card, passport photo) may be input together.

Finally, if you select the 'Generate fine data code' button after entering all the ID photo data, the image information registered by the fine data code system 200 performs an encoding process to perform a micrometer or nanometer sized barcode. Can be created (converted) to (C1 or C2). Here, the barcode may be a one-dimensional barcode C1 or a two-dimensional barcode QR code C2, but other types of codes may be adopted in the present invention. At this time, the micrometer- or nanometer-sized barcode (C1 or C2) is only shown so that it can be visually confirmed for convenience of explanation, and the micrometer or nanometer-sized barcode (C1 or C2) according to the present invention is actually output. In the case of doing so, it is implemented as a micrometer or nanometer size barcode that cannot be confirmed by human eyes.

In the following description, a method of combining the fine barcode C1 according to the present invention described above with a partial region on a corresponding ID photo image and outputting the image will be described as an example.

Process of outputting fine data code

4 is a screen showing an example of outputting a fine data code to a partial region of an image according to an embodiment of the present invention.

Referring to FIG. 4 , the screen (A) shows that a barcode C1, which is a fine data code corresponding to the corresponding ID photo, is coupled to a partial region 10 of the ID photo image. For reference, for convenience of explanation, the size of the fine data code in the drawing may correspond to a size that can be visually confirmed, but in reality, it may correspond to a size that cannot be visually confirmed.

Subsequently, the screen (B) shows a state in which the fine barcode (C1) is combined and output to a partial area (10) of the ID photo image. This output process may be a method of directly printing on a partial area 10 on the identification photo image with a micro or nano printer. Also, as described above, Zion ink that can be confirmed only at a specific temperature may be used.

Meanwhile, when a UV barcode, which is another embodiment, is output, in a process of directly printing with a photo printer using UV ink, UV ink having reactivity (readability) in a wavelength range of about 100 nm to 380 nm may be used.

According to the present invention, although the fine barcode (C1) is printed on the partial area 10 of the ID photo image, it is actually a size that people cannot visually check, so personal information can be blocked from being leaked to the outside. In addition, since the fine barcode is output with Zion ink and can be checked only at a specific temperature, it can be read only by a predetermined image reading device 500 associated with the specific temperature, thereby increasing security.

In addition, in the drawing, a partial area 10 of the ID photo image is shown as a corner side, but unlike the drawing, a border area (ex white border) exists in the ID photo, and the partial area may correspond to the border area of the ID photo . For example, a person appears in the central area of the identification photo, and a border area may exist around the center area. A fine bar code may be combined with the border area. Of course, the edge area may also be configured to make it difficult to check the thickness with the naked eye.

The process of checking fine data codes

5 is a screen showing an example of checking image information by utilizing fine data codes on a previously printed image according to an embodiment of the present invention.

Referring to FIG. 5 , on a screen (A), a process of recognizing a fine barcode in a partial region 10 of an identification photo image previously printed through the image reading device 500 can be confirmed. The fine barcode recognized in this way is transmitted to the fine data code system 200 and performs a decoding process of decoding to retrieve image information corresponding to an ID photo image. The image information is provided to the manager terminal device 700 so that “photography date” information can be displayed as shown in screen (A).

Subsequently, screen (B) provides all of the searched image information to the administrator terminal device 700 when a separate authentication procedure is passed from the terminal device 600 of the legitimate image owner of the ID photo based on the searched image information. to “1. Recording date, 2. Portrait right holder information, 3. Photographer information, 4. Image purpose, 5. Expiration date, 6. Original image ”information can all be displayed.

At this time, the expiration date can be set manually or automatically according to the purpose of the image. As shown in screen (B), “4. In the case of “use of image: for taking the O exam”, the ID photo on the application form is within 3 months according to the regulations of the test, and you can check whether the photo was taken in accordance with the standard size (2.5 × 3.0cm) of the image, and you can take the test It can be efficiently verified by comparing the identification photo on the original document with the original image 20. In addition, since a separate authentication procedure has been passed according to the importance (personal information) of the image information, security can be enhanced.

The manager terminal device 700 may check whether or not the ID photo on the application form meets the regulations and display the result on the manager terminal device 700 . Specifically, it can be displayed by determining whether the valid period, standard size, etc. of the ID photo meet the regulations. This can also be applied to various regulations pre-stored in the fine data code system 200 or the manager terminal device 700, and for example, it will be possible to check whether a photograph of a work matches the regulations of an exhibition to be displayed.

For reference, as described above, in the authentication process, an authentication code is transmitted to the image owner terminal device 600, and approval can be achieved by inputting the authentication code into the image owner terminal device 600 by the owner. In some cases, an authentication code may be transmitted to the image owner terminal device 600, and approval may be made by the owner inputting the authentication code into the manager terminal device 700 instead of the image owner terminal device 600.

The authentication procedure and the like are not limited to ID photos, and may be applied to other work photos, computer graphic images, and the like.
