Contact Token Authentication for Secure Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current contact information databases, such as ENUM servers and DNS databases, are not user-friendly and lack effective encryption and source user identification, making it difficult for target users to manage and secure their contact information in data communication systems.
Innovation Solution
A communication circuitry system that associates data sources with source IDs and cryptographic keys, and data targets with target IDs, contact tokens, and contact information, enabling authentication, validation, and secure transfer of contact information based on predefined conditions, using encryption and smart contracts in a distributed ledger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contact information is stored in public databases like ENUM servers and DNS databases, then contact information discovery is enabled, but security and source user identification are insufficient
Solution Approach 1:
The patent introduces a communication circuitry system that acts as an intermediary between data sources and data targets. This intermediary authenticates source users, validates contact tokens, and securely manages contact information distribution, resolving the contradiction between easy discovery and reliable identification by adding a trusted mediation layer
2Ease of operation
If contact information is made readily discoverable through telephone directories and web sites, then communication accessibility is improved, but security and encryption support are lacking
Solution Approach 1:
The patent implements local quality by providing different levels of contact information access to different source users based on authentication results. The communication circuitry selectively distributes contact information with appropriate encryption and access controls, allowing broad accessibility while maintaining security through differentiated access rights
3Adaptability or versatility
If ENUM servers return contact information to multiple source users, then communication flexibility is enhanced, but control over who receives information is reduced
Solution Approach 1:
The patent implements feedback mechanisms where the communication circuitry receives authentication results from source users and uses this feedback to control contact information distribution. The system continuously validates contact tokens and adjusts information distribution based on authentication status, enabling both flexibility and target user control through dynamic feedback-driven decisions
Data Source
AI summary
Communication circuitry associates a data source with a source Identifier (ID) and a cryptographic key and associates a data target with a target ID, contact token, contact condition, and contact information. The communication circuitry receives and decrypts the encrypted source ID, the encrypted target ID, and the encrypted contact token with the cryptographic key, and in response, authenticates the source ID, authenticates the target ID, and validates the contact token. When the authentication and validation are successful, the communication circuitry selects a portion of the contact information based on the contact condition, encrypts the selected contact information, and transfers the encrypted selected contact information to the data source. The data source uses the selected contact information and the contact token to transfer data to the data target. The data target uses the contact token to validate the data source.
