Image File Dual-Region Storage for Secure Annotation Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image file formats lack mechanisms to securely and conveniently handle information for annotation, particularly in a format that allows high flexibility and ensures the security and authenticity of binary-formatted data.
Innovation Solution
The implementation of a dual recording region system in image files, where accessory information is recorded in a binary format in a first region and encrypted derived information is stored in a text format in a second region, enhancing security and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If accessory information is recorded only in binary format in the first recording region, then the image file maintains compatibility with existing formats, but the flexibility and ease of management for annotation information is reduced
Solution Approach 1:
The recording region is divided into two distinct parts: a first recording region for binary-formatted accessory information and a second recording region for text-formatted derived information. This segmentation allows each region to serve its specific purpose optimally while maintaining overall system compatibility.
Solution Approach 2:
Text-formatted derived information acts as an intermediary between the binary accessory information and user applications. The derived information is generated from accessory information and provides a user-friendly interface for management and editing operations.
2Ease of operation
If accessory information is stored in text format, then ease of management and editing is improved, but security and authenticity of the original binary data is compromised
Solution Approach 1:
The system segments information storage into two regions: the first recording region stores binary-formatted accessory information that maintains security and authenticity, while the second recording region stores text-formatted derived information that enables easy management and editing.
Solution Approach 2:
The system creates a copy of the accessory information in text format (derived information) for management purposes, while the original binary information remains intact in the first recording region. This copying approach allows text-based operations without compromising the security of the original data.
3Adaptability or versatility
If a single recording region is used for all information, then device complexity is reduced, but the ability to securely handle and flexibly manage different types of information is limited
Solution Approach 1:
The recording region is segmented into a first recording region for binary-formatted accessory information and a second recording region for text-formatted derived information. This segmentation enables secure handling of original data while providing flexible management capabilities for annotation information.
Solution Approach 2:
Different regions of the recording area are assigned different qualities and formats: the first recording region uses binary format for security and authenticity, while the second recording region uses text format for ease of management and editing. Each region's local characteristics are optimized for its specific function.

AI summary
An image file creation method includes: an acquisition step of acquiring recording information including accessory information that is recordable in a first recording region of an image file or derived information that is derived from the accessory information; and a recording step of recording the recording information in a second recording region of the image file.
