Image Puzzle Encoding for Secure Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for secure identification and authentication, such as electronic passports and encoded security information, face challenges in preventing the disclosure and misuse of personal information due to advancements in decoding techniques and internet propagation, leading to security weaknesses and information leaks.
Innovation Solution
A system that encodes original images into puzzle-type images, dividing them into pieces and rearranging them according to a designated pattern, with a database and server system to manage keycode values and patterns, ensuring that the original information can only be restored with the encoded image and authorized terminals, minimizing information disclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If security information is printed as an encoded code on identification cards, then the security information can be prevented from being disclosed to the general public, but the security is weakened because the security information can be obtained regardless of truth or false of the original identification card
Solution Approach 1:
The patent divides the encoded image into multiple image pieces that must be correctly assembled to reveal the security information. This segmentation prevents unauthorized access because simply obtaining the encoded code is insufficient - the pieces must be properly arranged using authentication, thereby maintaining security while preventing disclosure to unauthorized parties.
Solution Approach 2:
The patent introduces an authentication mechanism as an intermediary between the encoded code and the security information. The authentication server verifies the legitimacy of the encoded code before allowing reconstruction of the original information, thus ensuring reliability while maintaining information protection.
2Loss of information
If security information is stored in chips, magnetic cards, smart cards, or RFID tags with specific security devices, then the leak of information can be prevented, but the encoding technique must be continuously updated due to lack of long-term effectiveness and information leak is difficult to prevent upon using the security device
Solution Approach 1:
The patent uses printed encoded images that can be copied like regular images, eliminating the need for complex security devices such as chips, magnetic cards, or RFID tags. The security relies on the authentication of the encoded code rather than physical security features, thereby preventing information leaks while avoiding the complexity and vulnerability of electronic security devices.
3Reliability
If fine printing technology such as foil stripe insertion, minute character, florescent ink, pattern formation, intaglio printing, non-florescent paper, watermark, hologram, barcode is used, then copying or forgery of identification card can be prevented, but certain information indicated in the prints is disclosed to the public
Solution Approach 1:
The patent segments the encoded image into multiple pieces that must be assembled to reveal information. This prevents disclosure of personal information in the prints while maintaining forgery prevention, because the segmented pieces alone are meaningless and the authentication mechanism verifies legitimacy before information is revealed.

AI summary
Disclosed is a system for encoding an original image 10 using an image puzzle-type encoded image 20, and more particularly to a system for encoding an original image 10 using an image puzzle-type encoded image 20, in which an original image 10 including a photograph, a picture, a document, a character, a number, a fingerprint, or an iris image is divided into image pieces having a predetermined size and the divided image pieces are arranged according to a designated pattern so as to generate the image puzzle-type encoded image 20, so that it is possible to minimize the disclosure of information of the original image 10 using the image puzzle-type encoded image 20. The system includes an image encoding terminal 100 for converting the original image 10 into the encoded image 20 according to a image puzzling pattern so as to express the converted encoded image 20 on an encoded image expressing part 500, an image decoding terminal 200 for obtaining the encoded image 20 expressed on the encoded image expressing part 500 so as to restore the original image 10 according to the image puzzling pattern, and an image encoding server 300 for communicating with the image encoding terminal 100 and the image decoding terminal 200 so as to provide the image puzzling pattern.
