Image Processing Device Secure Sensitive Data Concealment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies face challenges in securely concealing sensitive information within images while maintaining control over whether this information can be restored, particularly in scenarios where irreversible methods like blotting out are used.
Innovation Solution
An image processing device equipped with a recognition unit to identify sensitive information, a processing unit to conceal the recognized parts, an encryption unit to encrypt this data, and a merging unit to combine processed and encrypted data, allowing for secure concealment with optional restoration control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If irreversible concealing methods such as blotting out are used, then security of concealed information is improved, but ability to restore the information is lost
Solution Approach 1:
The patent divides the image data into two separate segments: concealed image data (with sensitive information obscured) and encrypted original image data (stored separately with encryption). This segmentation allows the system to provide both secure concealment and restorable information by keeping the encrypted original data intact and separate from the concealed image, enabling restoration when needed while maintaining security during normal operation
Solution Approach 2:
The patent introduces encrypted original image data as an intermediary element that mediates between the concealed image and the need for information restoration. This encrypted data acts as a backup that can be decrypted and combined with the concealed image to restore the original information, thus providing a controlled mechanism for information recovery without compromising the security of the concealed image itself
2Reliability
If sensitive information is concealed in an image, then privacy protection is improved, but control over information restoration becomes difficult
Solution Approach 1:
The patent implements a dynamic information restoration control mechanism where the system can adaptively switch between displaying only the concealed image and displaying the restored original image based on authentication results. The control unit dynamically adjusts the output based on whether the user is authorized, providing versatile control over information restoration while maintaining privacy protection for unauthorized users
Solution Approach 2:
The patent incorporates an authentication feedback mechanism where the system checks user credentials and provides different outputs based on authentication results. If authentication succeeds, the system restores and displays the original image; if it fails, only the concealed image is displayed. This feedback-based control provides adaptability in information restoration while ensuring privacy protection

AI summary
An image processing device includes: a recognition unit configured to recognize a part of a confidential target from a captured image; a processing unit configured to process the captured image such that the part recognized by the recognition unit is concealed; an encryption unit configured to encrypt data relating to the part recognized by the recognition unit; and a merging unit configured to merge data of the image processed by the processing unit and the data encrypted by the encryption unit.
