<Example: Information Security Method>

7 is a flowchart illustrating a method for generating a key code and a method for recovering an original image in an information security method using an image puzzle type key code according to an embodiment of the present invention.

Generation of the image puzzle-type keycode according to FIG. 7 is performed by registering the designated pattern to correspond to the keycode value in converting the original image 10 into the keycode image 20 according to the specified pattern. .

First, the original image 10 is photographed or scanned to process an image, or the original image 10 is received by receiving the original image 10 data stored as digital data in the memory device (S110).

The obtained original image 10 is divided into a plurality of image pieces having a predetermined size, and at the same time, each coordinate value is designated so that the divided image pieces can be identified (S120). At this time, it is preferable that the coordinate values are not specified for the image pieces formed of the background surface that do not characterize the original image 10. For example, it is preferable to exclude image fragments including the background picture except for the face image from the ID picture because it is not information characterizing the ID picture. In addition, even in the original image 10 consisting of letters or numbers, only the fonts of letters or numbers represent actual information.

Next, a keycode value to be expressed as a keycode image 20 and a pattern for arranging the divided image pieces to complete the keycode image 20 are designated, and the specified keycode value and pattern are stored in a database. It becomes (S130). Since the keycode value is a unique code assigned to the original image 10, it is preferable that the keycode value is specified differently from a keycode value corresponding to another original image. Also, the pattern for arranging the divided image fragments may be a pattern generated by a random number generator so as not to be designated only as a predetermined pattern, or after generating a plurality of patterns in advance and designating a randomly selected pattern as necessary. It is desirable to maintain security. In this case, the pattern includes a coordinate value designated for each image piece in step S120 and a coordinate value on the key code image 20 corresponding to each image piece.

The image pieces obtained in the step S120 are arranged according to the pattern selected in the step S130 to form a keycode image 20 so that the keycode value is expressed (S140). That is, according to the keycode image formation pattern, each image piece is arranged one-to-one at a position on the keycode image 20, and the completed keycode image 20 is an aspect of expressing the value of the selected keycode. .

The key code image 20 completed in step S140 is outputted to be printed on an ID card or a security, or stored in a magnetic card, a smart card or an RFID tag, and used by the user in real life.

The method 200 for recovering the original image 10 from the image puzzle type keycode formed by the above method reads the keycode image 20 to obtain a keycode value, and corresponds to the obtained keycode value. After designating the keycode image forming pattern, the respective image pieces included in the keycode image 20 are restored to the original image 10 in the reverse process of the pattern.

To describe in more detail, first, the keycode image 20 displayed on the printed matter is obtained by photographing or scanning, or the keycode image 20 data stored in the magnetic card, the smart card or the RFID tag is acquired (S210).

In general, the keycode image 20 obtained from the printed matter is image-processed to read the keycode value, and the keycode image 20 data stored in the magnetic card, smart card or RFID tag analyzes the data to read the keycode value. do.

After performing the reading step, the keycode image pattern of the step S130 corresponding to the read keycode value is designated (S230). Since the pattern is stored in the database so as to correspond to the keycode value one-to-one, the keycode image formation pattern selected in step S130 may be known using the keycode value as an inquiry value.

Next, a plurality of image pieces are obtained by dividing the keycode image 20 by the size of the image pieces used in the step (S120), and at the same time, each coordinate value is set so that the divided image pieces can be identified. It is specified (S240).

Finally, the obtained image pieces are rearranged to the inverse of the pattern to complete the original image 10 (S250). That is, in step (S140), the key piece image 20 is generated by mapping the image piece coordinates on the original image 10 to the image piece coordinates on the key code image 20. However, in step S250, the key code image is generated. The image fragment coordinates on the image 20 correspond to the image fragment coordinates on the original image 10 to recover the original image 10.

After performing the step (S250), the user can check the restored original image (10). In the embodiment to which the original image 10 recovery method (S200) is applied, when applied to fingerprint recognition of the ePassport, the original image 10 is recovered from the keycode image 20 obtained in the ePassport as described above. After that, the fingerprint of the ePassport holder can be obtained by using a fingerprint reader, and the identity of the ePassport holder can be confirmed by comparing the fingerprint or photograph with electronic or naked eyes.
