Biometric Image Watermarking for Secure Image Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing availability of high-quality visual content on the Internet poses a risk of unauthorized access to personal identification information through biometric data, necessitating a method to secure images and prevent leakage of such data.
Innovation Solution
An electronic device employs an image processing method that searches for biometric data, encodes it using a watermark and a preset encryption key, and synthesizes it with the original image to maintain visual quality while preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric data is processed to prevent leakage, then security is improved, but image quality or usability may deteriorate
Solution Approach 1:
The image processing method segments the image into multiple regions, identifying and separately processing the biometric data region. This allows selective encoding of only the biometric portion while preserving the rest of the image quality, thus preventing information loss in non-biometric areas while securing the sensitive biometric data.
Solution Approach 2:
The patent applies different processing qualities to different regions of the image. The biometric region receives encoding processing to prevent leakage, while other regions maintain their original quality. This local differentiation resolves the contradiction by applying security measures only where necessary rather than degrading the entire image.
2Reliability
If biometric data is encoded and synthesized with watermark, then security against unauthorized access is improved, but processing complexity increases
Solution Approach 1:
The patent performs preliminary encoding of the biometric data region before final image synthesis. By pre-processing the biometric region with encoding and watermark integration in advance, the system simplifies the overall processing pipeline and reduces the complexity of real-time or post-processing operations needed to maintain security.
Solution Approach 2:
The patent combines multiple security functions into a unified processing step. The encoding of biometric data, watermark generation, and image synthesis are merged into a single integrated process, reducing the number of separate operations and thereby decreasing overall processing complexity while maintaining security.
3Ease of operation
If high-quality visual content is shared widely, then accessibility and usability are improved, but risk of unauthorized access to biometric data increases
Solution Approach 1:
The patent applies preliminary protective encoding to the biometric data region before the image is shared or distributed. This pre-emptive security measure counteracts the potential harm of unauthorized access that would otherwise occur when high-quality images are widely shared, allowing accessibility without proportionally increasing security risks.
Solution Approach 2:
The encoded biometric region acts as an intermediary layer between the original biometric data and potential unauthorized access. The encoding and watermarking create a protective barrier that mediates between the need for image sharing and the need to prevent biometric data theft, allowing both accessibility and security to coexist.

AI summary
The present disclosure relates to a method of setting security on an image. In detail, the method of setting security on an image including biometric data includes: searching for a region including the biometric data in a first image; detecting a biometric image corresponding to the biometric data in the searched region; encoding the detected biometric image; and generating a second image by synthesizing a watermark for blocking access to the biometric data, the first image, and the encoded biometric image.
