Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current random number generation methods, particularly pseudorandom number generators, are vulnerable to prediction and hacking, as they rely on deterministic algorithms and seed values that can be reproduced, posing security risks in applications like computer security and cryptography.
Innovation Solution
An apparatus and method that utilize a user's unique electrical body resistance measured through conductive surfaces on input devices like keyboards or touchpads to generate random numbers, making them unpredictable and resistant to malicious access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pseudorandom number generators are used to generate random numbers quickly, then productivity is improved, but reliability deteriorates because the numbers can be predicted and reproduced if the seed is known
Solution Approach 1:
The patent introduces an intermediary measurement device that physically measures electrical body resistance as a mediator between the user and the random number generation system. This physical measurement serves as an unpredictable seed that bridges the gap between deterministic algorithms and true randomness, allowing fast generation while maintaining security through the unique physical characteristic of each user's body resistance.
2Reliability
If true random number generators are used to ensure unpredictability, then reliability is improved, but productivity deteriorates because true random numbers are difficult to generate
Solution Approach 1:
The patent changes the parameter used for random number generation from traditional sources (atmospheric noise, radioactive decay) to electrical body resistance measurements. This parameter change enables fast generation speeds comparable to pseudorandom generators while maintaining true randomness, as the measurement captures unique physiological variations that are inherently unpredictable and cannot be reproduced.
3Ease of operation
If pseudorandom number generators are used, then ease of operation is improved, but object-generated harmful factors worsen because malicious software can hack into the system to steal information
Solution Approach 1:
The patent extracts the critical security dependency from the computational domain and moves it to the physical domain. By using electrical body resistance measurements as the seed source, the system removes the vulnerability associated with software-based pseudorandom generators. The physical measurement cannot be replicated by software hackers, thereby eliminating the harmful factor of data theft while maintaining ease of operation through automated measurement and generation.
