Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If preset security features are used in physical identification cards, then verification process is simple, but the system is vulnerable to fraud and counterfeiting
Solution Approach 1:
The patent applies dynamics by transitioning from static preset security features to dynamic encrypted credential data that can be updated in real-time. The encryption keys and credential data can be changed without reissuing the entire card, making the security features adaptable and resistant to counterfeiting while maintaining verification simplicity through the same optical scanning interface.
Solution Approach 2:
The patent changes the parameter of security features from fixed physical elements to variable encrypted data. By using encryption algorithms and keys that can be modified, the system maintains the simple verification process while significantly improving security against fraud and counterfeiting through parameter variability.
2Measurement precision
If physical identification cards are reissued when user information changes, then data accuracy is maintained, but user convenience deteriorates due to waiting time
Solution Approach 1:
The patent implements preliminary action by pre-configuring the digital identification card with update capabilities and encrypted storage structures. When user information changes, the system can immediately update the encrypted credential data without requiring physical card reissuance, thus maintaining data accuracy while eliminating the time loss associated with traditional card replacement processes.
Solution Approach 2:
The patent uses copying by creating a digital replica of the identification card that can be updated independently of the physical card. The encrypted credential data in the digital copy can be modified in real-time to reflect current user information, maintaining accuracy without the delays of physical reissuance.
3Reliability
If encrypted credential data is embedded in digital identification, then security against fraud is improved, but device complexity increases due to decryption requirements
Solution Approach 1:
The patent replaces mechanical security verification with cryptographic verification. Instead of complex physical security features that require manual inspection, the system uses encryption and decryption algorithms that can be automatically processed by digital devices, improving security while actually simplifying the verification process through automation.
Solution Approach 2:
The patent introduces an intermediary decryption key mechanism that mediates between the encrypted credential data and the verification process. This intermediary layer allows the system to maintain high security through encryption while managing complexity through standardized key management and decryption protocols.
4Speed
If optical scanning is used to extract encrypted data, then verification speed is improved, but measurement precision may be affected by scan quality
Solution Approach 1:
The patent applies preliminary action by pre-optimizing the optical scan design and error correction codes during the card creation process. This ensures that even if scan quality varies, the encrypted credential data can be accurately extracted and decrypted, maintaining both verification speed and data extraction precision through advance preparation.

AI summary
In general, one innovative aspect of the subject matter described in this specification may be embodied in methods that may include verifying a digital identification using embedded encrypted user credential data that is not viewable to human eyes within the digital identification. For instance, the embedded encrypted user credential data may be variably encrypted by an encryption key that is designated by a security status assigned to the digital identification. The embedded encrypted user credential data may be extracted using an authorized device and decrypted using a decryption key that is associated with the encryption key designated by the security status. The decrypted user credential data may then be used to verify user information included in the digital identification.
