Biometric Authentication via Embedded Image Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face security risks due to the exposure of authentication information when storing passwords or other sensitive data on devices, making them vulnerable to unauthorized access and data theft.
Innovation Solution
A system and method that generates a unique identifier using a digital image with an embedded code, such as personal or randomly generated data, which is encrypted and stored in unused image bits, allowing secure authentication without storing sensitive data on target devices, and includes a 2-step verification process using a mobile phone for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If authentication information is stored on user devices for convenient access, then ease of operation is improved, but security and vulnerability to hacking worsen
Solution Approach 1:
The patent extracts sensitive authentication information from the user device by using biometric data captured by the camera. Instead of storing passwords or authentication credentials on the device, the system captures biometric information (face, fingerprint, iris) and uses it for authentication, removing the vulnerability of stored authentication data while maintaining convenient access.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism using biometric verification. Instead of directly using stored passwords or authentication credentials, the system uses biometric data as an intermediary that verifies user identity without exposing sensitive authentication information that could be hacked from the device.
2Reliability
If passwords are stored on devices for authentication, then authentication functionality is improved, but exposure to data theft worsens
Solution Approach 1:
The patent extracts authentication functionality from stored passwords and implements it using biometric data captured in real-time. The authentication reliability is maintained through biometric verification while the exposure to data theft is eliminated because no authentication credentials are stored on the device that could be stolen.
Solution Approach 2:
The patent uses disposable biometric authentication sessions instead of persistent stored passwords. Each authentication uses freshly captured biometric data that is processed and discarded, rather than relying on long-term stored credentials that could be compromised. The biometric data is captured, verified, and then discarded, preventing data theft.

AI summary
A system and method for generating a unique identifier for a user. A processor hosted by the system transmits a prompt for user selection of a digital image and receives the selected digital image from the user. The received digital image is stored in a data storage device. The processor identifies a first code associated with the user. The processor embeds the first code into the digital image and generates a first modified digital image in response. The first modified digital image is also stored in the data storage device. The processor transmits the first modified digital image to the user over a data communications network. The modified digital image is then used as the unique identifier for the user.
