Solution Overview

Problem

Current image data protection methods, such as MIPI SSPIE, fail to securely encrypt the most important portions of image data, leaving them vulnerable to spoofer attacks.

Innovation Solution

Implement task-based, attention-based, and threat-dependent MAC modes to selectively encrypt critical image pixels, ensuring secure transmission of image data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current image data protection methods (MIPI SSPIE) are used, then image data can be transmitted, but the most important portions of image data are not securely encrypted and remain vulnerable to spoofer attacks

Engineering Contradiction:

Improvedata integrityVSAvoidvulnerability to spoofer attacks

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent divides the image data into multiple regions of interest (ROIs) based on task-based authentication requirements. Different regions are encrypted separately using MAC modes selected according to their specific security needs, allowing selective protection of critical areas while maintaining overall data integrity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies different encryption strengths and MAC modes to different regions of the image data. Critical regions requiring higher security get stronger encryption, while less critical regions use lighter encryption, optimizing the balance between security and processing resources

Inventive Principle:

Principle #3Local quality

2Reliability

If selective encryption of critical image portions is implemented, then data integrity is enhanced and spoofer attacks are prevented, but processing complexity and computational resources increase

Engineering Contradiction:

Improvedata integrityVSAvoidencryption processing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent dynamically selects which MAC modes to apply based on the specific task requirements and identified regions of interest. The system adapts the encryption strategy in real-time based on image content analysis and security needs, rather than applying uniform encryption to the entire image

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Instead of encrypting the entire image data, the patent applies encryption only to the necessary portions (regions of interest) that require protection. This partial action approach reduces computational overhead while maintaining security for critical data

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Systems and techniques media for image processing are described herein. For example, a device can obtain encryption mode information associated with an image. The encryption mode information includes a region of interest (ROI) of the image and/or a task associated with the image. The device can encrypt at least a portion of image based on the encryption mode information to produce an encrypted image. The device can transmit the encrypted image.
