Dynamic Verification Code for Identity Document Forgery Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identity document authentication methods are vulnerable to forgery, especially when copies are made, as they lack reliable verification of authenticity and can be easily falsified, allowing identity theft even with authentic copies.
Innovation Solution
A method involving a dynamic verification code displayed on electronic identity devices, which includes reference information about personal visual elements and a one-time password, is used to authenticate the identity by matching candidate information from an acquired image with server-stored reference information, ensuring the visual elements have not been altered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If copies of identity documents are made for various purposes, then the convenience of use is improved, but the security against forgery deteriorates
Solution Approach 1:
The patent applies preliminary action by embedding a dynamic verification code on the identity document before copying occurs. This code contains reference information about visual elements and expires after a predetermined time, proactively preventing future forgery issues rather than reacting to them after copies are made and distributed.
Solution Approach 2:
The patent implements dynamics by using a dynamic verification code that changes over time and expires after a predetermined period. This transforms the static identity document into a dynamic system where the verification capability is time-limited, preventing long-term misuse of copies while maintaining convenience for legitimate uses.
2Reliability
If a dynamic verification code with expiration is implemented, then the security against identity theft is improved, but the device complexity increases
Solution Approach 1:
The patent applies copying by extracting reference information from the visual elements already present on the identity document (photo, signature, etc.) and embedding it within a dynamic verification code. This reuses existing visual elements rather than introducing entirely new complex components, thereby improving security while limiting the increase in device complexity.
3Measurement precision
If visual elements are dynamically validated, then the authenticity verification is improved, but the processing time increases
Solution Approach 1:
The patent replaces complex mechanical or manual verification processes with automated image processing and pattern recognition algorithms. The server extracts reference information from uploaded images of the identity document and compares it with the dynamic verification code, substituting manual authenticity checks with efficient computational processes that reduce processing time while maintaining high verification precision.
