Computed Image Format Dynamic Rendering Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital image formats lack the necessary security and flexibility to control image copying and adapt to changing market requirements, particularly in applications like digital coupons and electronic boarding passes, where unauthorized copying and distribution can occur.
Innovation Solution
A new digital image format, referred to as the Computed Image Format (CIF), which includes both image data and executable code that can communicate with remote computers to generate dynamic image data, allowing for secure and flexible image rendering and display, with features such as program variables that can be updated and used to control image generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If digital images are stored in conventional formats (JPEG, GIF), then storage compression is achieved, but image copying control and security are lost
Solution Approach 1:
The patent combines image data with executable code in a single digital image format. The image file contains both the visual data and program instructions that control how the image is rendered and displayed, merging functions that were previously separate into one integrated structure.
Solution Approach 2:
The patent introduces an intermediary rendering engine that acts as a mediator between the stored image data and the final display. This rendering engine executes the executable code within the image format, controlling the image generation and display process to prevent unauthorized copying while maintaining storage efficiency.
2Ease of operation
If digital images are made static and standardized, then rendering compatibility is improved, but adaptability to changing requirements is reduced
Solution Approach 1:
The patent transforms the static nature of conventional image formats by embedding executable code that can dynamically generate and modify image data. The image format evolves from a fixed structure to a dynamic system where the rendering engine can adapt to changing requirements while maintaining compatibility through standardized execution environments.
Data Source
AI summary
An image format and method are presented for storing a digital image in the image format. The image format includes image data and executable computer instructions. Displaying a digital image stored in this image format requires executing the stored executable instructions which generate the image data for the associated digital image.
