Security Device Data Encryption via Biometric Crypto-Biometric Algorithms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production phase of security devices can be subcontracted, leading to a risk of confidentiality breaches during the manufacturing process, as the issuing body may not have direct control over the production chain.
Innovation Solution
The method involves encrypting confidential data using biometric information during the preparation phase, ensuring it remains masked throughout production, and decrypting it only upon activation using the same biometric information, employing 'crypto-biometric' algorithms and a processing unit within the security device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If confidential data is stored in plaintext during production, then the production process is simple and efficient, but the confidentiality of sensitive data is compromised
Solution Approach 1:
The patent applies preliminary action by encrypting confidential data before the production phase begins. The encryption is performed in advance during the preparation phase, so that when data is stored in the security device during production, it is already in encrypted form. This preliminary encryption action ensures confidentiality is maintained throughout production without requiring complex real-time security measures during manufacturing.
Solution Approach 2:
The patent uses an intermediary approach by introducing encryption algorithms and key management systems as mediators between the confidential data and the production environment. The encrypted data acts as an intermediary representation that preserves confidentiality while allowing production processes to proceed. The decryption key serves as another intermediary that enables controlled access only when needed.
2Reliability
If biometric verification is required for decryption, then data security is enhanced, but the activation process becomes more complex and time-consuming
Solution Approach 1:
The patent applies preliminary action by collecting and verifying biometric information during the initial preparation phase, before production begins. The biometric data is stored and prepared in advance, so that during activation, the system only needs to perform a comparison rather than full verification. This preliminary preparation reduces the time required during the actual activation process while maintaining strong security.
Solution Approach 2:
The patent replaces traditional mechanical or manual authentication methods with biometric verification systems. Instead of requiring physical presence or manual verification procedures, the system uses automated biometric recognition (such as fingerprint, facial, or iris recognition) to rapidly verify identity. This substitution reduces activation time while enhancing security compared to conventional methods.
3Reliability
If decryption is restricted to a single operation, then unauthorized access is prevented, but legitimate access may be lost if decryption fails
Solution Approach 1:
The patent applies beforehand cushioning by implementing error correction codes and redundancy mechanisms in advance of the decryption operation. The system prepares backup verification data and error correction capabilities during the preparation phase, so that if the decryption operation encounters errors or failures, the system can recover and succeed without requiring a second decryption attempt. This cushioning approach maintains the single-operation restriction while ensuring access reliability.
Solution Approach 2:
The patent uses feedback mechanisms by implementing verification checks during the decryption process that provide real-time information about the operation's progress and success probability. The system monitors the decryption operation and can detect potential failures before they complete, allowing for corrective actions or alternative verification methods to be triggered. This feedback loop ensures that the single decryption operation is highly likely to succeed while maintaining security.
