Multi-stage Data Encoding for End-to-End Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data security techniques fail to provide end-to-end protection for sensitive data, often compromise security if the code is cracked, lack flexibility in tailoring security levels for different entities, and do not effectively respond to security threats like data breaches.
Innovation Solution
A method involving a server with a registry database that uses multiple identifiers and secure communication channels to encode and decode data strings across multiple devices, ensuring that each device in the communication path receives the necessary identifier values to perform specific encoding and decoding operations, thereby maintaining data security and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple encoding stages are used across different devices in the communication path, then end-to-end security protection is improved, but device complexity and system complexity increase
Solution Approach 1:
The patent divides the encoding process into multiple segments, with each device in the communication path (source device, intermediary devices, destination device) performing a specific encoding operation using its own identifier. This segmentation ensures that if one encoding stage is compromised, other stages remain secure, thereby improving end-to-end security protection while distributing the complexity across multiple devices rather than concentrating it in one system.
Solution Approach 2:
The patent implements nested encoding where each device's encoding operation is applied to the output of the previous device's encoding. The source device encodes the original data, then each intermediary device encodes the already-encoded data from the previous device, creating layers of encoding like nested dolls. This nested structure provides cumulative security protection while organizing the system complexity in a hierarchical manner that is manageable through the registry database.
2Adaptability or versatility
If a centralized registry database is used to manage identifiers for multiple entities, then security management flexibility is improved, but server complexity increases
Solution Approach 1:
The registry database serves multiple functions: it stores identifiers for all entities in the communication path, manages the distribution of these identifiers to appropriate devices, and enables the server to adapt to different security requirements for different entities. This multi-functional approach provides security management flexibility while consolidating the complexity into a single centralized database rather than requiring complex distributed management systems.

AI summary
In a method for providing secure communication of a data string along a communication path, a first entity and first identifier, and a second entity and second identifier, are added to a registry database. A current value of the first identifier is provided to a first device to enable a first encoding of the data string, where the first encoding encodes a plurality of bit sequences in the data string as a first plurality of encoded bit sequences. A current value of the second identifier is provided to a second device downstream of the first device to enable a second encoding of the data string, where the second encoding encodes the first plurality of encoded bit sequences as a second plurality of encoded bit sequences. The current values of the first and second identifiers are provided to a third (e.g., destination) device to enable decoding of the data string.
