Smart Terminal Face Recognition Image Protection Flag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often accidentally delete important images containing specific individuals, such as people, from their smart terminals, and there is a need for a method to protect these images from unintended deletion.
Innovation Solution
Implementing a face recognition system on smart terminals that sets a protection flag for images containing recognized individuals in a protection list, preventing accidental deletion by ignoring deletion instructions for flagged images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user deletes images from a folder in a smart terminal, then the user can manage and organize images, but important images may be accidentally deleted and cannot be recovered
Solution Approach 1:
The system performs preliminary face recognition and identification before deletion occurs. By proactively identifying images containing important persons and setting protection flags before the deletion operation, the system prevents accidental deletion while maintaining normal deletion functionality for non-protected images.
Solution Approach 2:
The system provides visual feedback by marking protected images with protection flags and displaying prompts to users during deletion operations. When a user attempts to delete a protected image, the system feeds back a warning message and requires explicit confirmation, making the protection mechanism visible and controllable.
2Reliability
If the system sets protection flags for all images containing recognized faces, then important images are protected, but the system complexity increases due to face recognition and matching operations
Solution Approach 1:
The system automatically performs face recognition, identification, and protection flag setting without requiring manual user intervention. The terminal device itself provides the protection service by autonomously identifying images containing important persons and applying protection flags, reducing the need for complex user configurations.
Solution Approach 2:
The system creates a protection list as a copy of important face images and uses this list for rapid matching against new images. Instead of performing full face recognition on every image, the system compares new images against the stored protection list, significantly reducing computational complexity while maintaining protection reliability.
3Measurement precision
If the system performs face recognition on every image to determine protection status, then accurate protection is achieved, but the processing time and energy consumption increase
Solution Approach 1:
The system performs face recognition and creates the protection list in advance, before actual deletion operations occur. By pre-identifying and storing face images of important persons, the system avoids performing full face recognition on every image during deletion operations, significantly reducing processing time while maintaining accuracy.
Solution Approach 2:
The system creates a protection list containing face images of important persons and uses this copy for efficient matching. Instead of performing full face recognition on every image, the system compares images against the pre-created protection list copy, reducing computational time and energy consumption while maintaining recognition accuracy.

AI summary
The disclosure discloses a method and apparatus for protecting an image based on face recognition, the method including: recognizing, by a smart terminal, at least one face image in an image; setting, by the smart terminal, a protection flag for the image, and storing the image, upon determining that one of the at least one face image in the image matches successfully with one of face images in a protection list stored in the smart terminal, wherein the protection flag is configured to protect the image from accidental deletion.
