Nucleic Acid Barcoding for Genetic Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack effective solutions for concealing nucleic acids prior to analysis, which is crucial for maintaining privacy, especially in genetic studies and data storage applications, as existing approaches primarily focus on genomic data rather than the nucleic acids themselves.
Innovation Solution
The method involves generating and affixing unique barcodes to nucleic acids in a secure facility, followed by pooling them with other barcoded nucleic acids to conceal their identity, source, and information, using secure facilities with electromagnetic shielding and air-gapped systems to prevent information leakage, and employing techniques like sticky-end ligation and restriction enzymes for barcode integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nucleic acids are pooled with barcodes for limited concealment, then sample identification is improved, but genetic information privacy is compromised
Solution Approach 1:
The patent introduces an intermediary encoding layer where nucleic acid sequences are converted into encoded sequences through a coding scheme. This intermediary representation allows the data to be processed and analyzed while maintaining privacy, as the encoded form does not directly reveal the original genetic information. The barcode serves as another intermediary that enables tracking without exposing genetic content.
Solution Approach 2:
The patent creates encoded copies of the original nucleic acid sequences rather than analyzing the originals directly. These encoded sequences contain the necessary information for analysis but in a transformed format that protects privacy. Multiple copies with different encodings can be distributed and analyzed independently, maintaining both utility and confidentiality.
2Productivity
If nucleic acid sequence data is shared for analysis, then research productivity is improved, but privacy protection deteriorates
Solution Approach 1:
The patent transforms the nucleic acid data by changing its parameters through encoding schemes. The encoded sequences have different numerical or symbolic representations compared to the original sequences, allowing them to be shared and analyzed without revealing the underlying genetic information. This parameter transformation enables productivity while maintaining privacy boundaries.
3Ease of operation
If barcodes are affixed to nucleic acids for tracking, then sample management is improved, but information about nucleic acids becomes more vulnerable to adversaries
Solution Approach 1:
The patent performs preliminary encoding of the nucleic acid sequences before they are shared or analyzed. This preliminary action of encoding creates a protective layer that remains in place throughout subsequent handling and analysis. The barcode is affixed to this already-encoded representation, ensuring that even if the barcode information is accessed, the underlying genetic information remains protected by the encoding scheme.
