Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional data securing methods are used in financial transactions, then data confidentiality can be maintained, but efficient data recovery and controlled access cannot be achieved
Solution Approach 1:
The patent divides data into multiple encrypted layers, where each layer is protected by different cryptographic keys. This segmentation allows selective decryption and recovery of specific data portions without compromising the entire data structure, enabling controlled data access while maintaining overall security.
Solution Approach 2:
The patent implements a nested encryption structure where encrypted data layers are contained within each other. The first encrypted data layer contains the second encrypted data layer, creating a nested configuration that allows sequential decryption from outer to inner layers, providing both security and structured recovery capability.
2Adaptability or versatility
If multi-layer tokens with multiple encrypted data layers are implemented, then controlled data recovery and authorization validation are enabled, but system complexity increases
Solution Approach 1:
The multi-layer token structure serves multiple functions simultaneously: it provides data encryption, authorization validation, and recovery control. By embedding multiple data layers with different cryptographic keys within a single token structure, the system achieves versatile functionality without requiring separate mechanisms for each purpose.
Solution Approach 2:
The patent introduces data pointers as intermediary elements that link encrypted data layers to corresponding database entries. These pointers facilitate the validation and recovery process by mediating between the encrypted token structure and the underlying data storage, simplifying the complex interaction required for authorized data access.
3Reliability
If cryptographic keys and encrypted data layers are processed, then secure data transmission is achieved, but processing time and computational resources increase
Solution Approach 1:
The patent performs encryption and key management operations in advance during token generation. By pre-establishing the multi-layer encrypted structure and storing cryptographic keys in the token database before data transmission, the system reduces computational overhead during actual data processing operations, as the encryption framework is already in place.
Data Source
AI summary
A message processing server includes a message processor and a database of multi-layer tokens. Each token in the database includes a plurality of encrypted data layers. The first layer includes the second layer and a first pointer. The second layer includes a second pointer. The message processor is configured to receive a first authorization message including a first cryptographic key and a second value; decrypt the first layer of one of the tokens with the first key; validate the first pointer by receiving confirmation of the first pointer pointing to a database entry comprising the second value; receive a second authorization message including a second cryptographic key and a third value; decrypt the second layer of the token with the second key; and validate the second pointer by receiving confirmation of the second pointer pointing to a database entry comprising a maximum data value not less than the third value.
