Engineering Contradiction Analysis
1Quantity of substance
If data is encoded and stored in DNA sequences in biological hosts, then large amounts of data can be stored, but replication errors and environmental conditions introduce inaccuracies that severely impact data reading accuracy
Solution Approach 1:
The patent applies preliminary action by embedding authentication tags and error-detecting codes into the DNA sequences before storage. This allows the system to proactively prepare for potential replication errors and environmental damage, enabling accurate data recovery even after biological degradation occurs during storage and replication cycles
Solution Approach 2:
The patent implements feedback mechanisms through authentication tags that verify data integrity during read operations. When DNA sequences are retrieved, the system checks the authentication tags to detect and correct errors introduced during biological storage, creating a closed-loop verification system that maintains data accuracy despite the noisy biological environment
2Reliability
If multiple types of DNA encoding methods are used for concealing data, then data security is enhanced, but each encoding type presents unique sequences and challenges that complicate the decoding process
Solution Approach 1:
The patent segments the decoding process into distinct modular steps: first verifying authentication tags, then applying appropriate decoding algorithms based on the encoded data type. This segmentation allows the system to handle multiple encoding methods systematically, reducing the overall complexity by breaking down the challenging multi-method decoding into manageable sequential operations
Solution Approach 2:
The patent uses parameter changes by detecting the encoding type through authentication tag verification and then dynamically selecting the appropriate decoding parameters and algorithms. This allows the system to adapt to different encoding methods without requiring complex simultaneous handling of all methods, simplifying the decoding process through parameter-based routing
3Ease of manufacture
If conventional DNA encoding methods are used without error detection mechanisms, then the encoding process is simpler, but there are no easy processes to limit errors read from data inserted into DNA
Solution Approach 1:
The patent implements self-service by having the DNA-encoded data carry its own authentication tags and error-detecting codes embedded within the sequence. When retrieved, the data autonomously verifies its own integrity through these built-in mechanisms, eliminating the need for complex external verification systems and maintaining simplicity while improving reliability
Solution Approach 2:
The patent applies preliminary action by pre-calculating and embedding authentication tags and error-detection codes during the DNA encoding phase. This preliminary preparation enables simple encoding processes to produce reliable output, as the error-detection capability is built in from the start rather than added as a complex post-processing step
Data Source
AI summary
A method is disclosed comprising encoding a message into blocks, determining a collection of DNA symbols for each of the blocks from the encoded message, performing a second encoding of the determined collection of DNA symbols from the encoded message, detecting a presence of errors in the second encoding and establishing an authentication of each block and further using zero-knowledge protocol to securely authenticate the message without disclosing the actual message.
