Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating electronic signatures lack effective visual verification to ensure trustworthiness, making them vulnerable to manipulation during data transmission and processing.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic signatures are generated using chip cards or mobile devices without visual verification, then the signature generation process is simple and fast, but the security and trustworthiness of the signature is compromised due to vulnerability to manipulation during data transmission
Solution Approach 1:
The patent introduces a visual intermediary (graphical representation of compression value) that mediates between the digital data transmission and the user's verification. This visual mediator allows the user to independently verify data integrity without requiring complex cryptographic verification procedures, thus enhancing reliability while maintaining process simplicity
Solution Approach 2:
The patent employs visual/graphical representations (analogous to color changes or visual transformations) of the compression value that allow users to quickly and intuitively verify data integrity. The graphical representation transforms abstract numerical data into visually distinguishable patterns that can be easily compared and verified by users
2Reliability
If visual verification is implemented by displaying compression values, then the security and verification capability is improved, but the time required for signature generation increases due to the additional verification step
Solution Approach 1:
The patent replaces complex mechanical/cryptographic verification mechanisms with a simplified visual comparison system. Instead of requiring users to perform or understand complex cryptographic verification, the system substitutes this with a simple visual comparison of graphical representations, dramatically reducing the time required while maintaining verification capability
Solution Approach 2:
The patent changes the parameter of verification from complex cryptographic data comparison to simple visual pattern recognition. By transforming the compression value into a graphical representation with distinct visual parameters, the verification process becomes much faster while maintaining its reliability
