Solution Overview

Problem

The use of electronic devices with display screens for confidential information in offices or meetings can lead to information leakage due to visibility of encoding codes, affecting security and user experience.

Innovation Solution

A method of encoding information on a display apparatus, adjusting pixel values of predetermined image regions, and fusing the encoded image with a target image to create a traceless encoded image, enhancing security and user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If encoding code is displayed on screen for information security, then security is improved, but user experience deteriorates due to visibility affecting display quality

Engineering Contradiction:
Improveinformation securityVSAvoiduser experience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies local quality by encoding information in specific predetermined regions of the display screen rather than across the entire screen. Different regions have different encoding characteristics, allowing the encoded information to be embedded in areas that minimize impact on overall display quality while maintaining security functionality.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes parameters by adjusting pixel values in predetermined regions according to encoded information. By modifying parameters such as pixel intensity and color within specific regions, the system embeds encoded data without significantly affecting the overall display quality, thus resolving the contradiction between security and user experience.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If encoding code is displayed on screen for information traceability, then traceability is improved, but display quality deteriorates due to visible encoding

Engineering Contradiction:
Improveinformation traceabilityVSAvoiddisplay quality
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent embeds encoded information in specific predetermined regions rather than distributing it across the entire display. This localized approach ensures that encoding operations are confined to areas that do not significantly impact overall display quality, while still achieving the goal of information traceability.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent applies partial action by encoding information only in predetermined regions rather than the entire screen. This partial encoding approach is sufficient to achieve traceability goals while minimizing the impact on display quality, avoiding the need for full-screen encoding that would degrade visual output.

Inventive Principle:
Principle #16Partial or excessive action

3Reliability

If pixel values are adjusted for encoding information, then information security is improved, but image quality deteriorates due to pixel manipulation

Engineering Contradiction:
Improveinformation securityVSAvoidimage quality
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent adjusts pixel values only in predetermined regions rather than across the entire image. This localized pixel manipulation confines quality degradation to specific areas that are less perceptible, while maintaining overall image quality and achieving the security objective.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent creates an encoded version of the image by adjusting pixel values in predetermined regions, effectively creating a copy that contains embedded information. This copying approach allows the original image quality to be preserved while the encoded version carries the security information.

Inventive Principle:
Principle #26Copying

AI summary

Provided is a method of processing an image, an electronic device, and a storage medium. The method of processing an image includes: encoding a first to-be-encoded information corresponding to a display apparatus, so as to obtain a first encoded information; adjusting a pixel value of at least one first predetermined region of a to-be-encoded image according to the first encoded information, so as to obtain a first encoded image, wherein the to-be-encoded image corresponds to a target image; and fusing the target image with the first encoded image to obtain a fused image.
