Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reversible encryption function is used to protect genome data, then data security is improved, but the risk of data leakage increases due to computational power advancements
Solution Approach 1:
The patent extracts only the necessary information (response data) from the genome data through the one-way function, separating the useful information from the sensitive original data. The terminal device generates response data by applying a one-way function to the genome data, allowing queries to be answered without exposing the original genome information, thus taking out only what is needed while preserving security.
Solution Approach 2:
The patent introduces an intermediary mechanism (one-way function) between the genome data and the response data. This intermediary transforms the sensitive genome data into response data that can be transmitted and processed without revealing the original data. The one-way function acts as a mediator that allows information flow while maintaining security, as it can be applied easily but cannot be reversed.
2Object-affected harmful factors
If one-way function is applied to genome data, then data leakage is prevented, but computational complexity increases
Solution Approach 1:
The patent creates a copy of the genome data transformed through the one-way function to generate response data. Instead of storing or transmitting the original sensitive genome data, the system works with this transformed copy (response data) that contains only the necessary information. The one-way function creates a mathematical copy that preserves queryability while eliminating direct access to the original data, and this copying process is computationally efficient in the forward direction.
3Measurement precision
If original genome data is accessed for estimation, then estimation accuracy is improved, but security protection deteriorates
Solution Approach 1:
The patent uses the one-way function as an intermediary that allows estimation operations to be performed on transformed data rather than original data. The terminal device applies the one-way function to the genome data to create response data, which can then be used for estimation purposes. This intermediary enables the system to maintain security protection while still achieving the necessary estimation accuracy, as the one-way function preserves the mathematical relationships needed for accurate estimation without exposing the original data.
