Trusted Caller ID Retrieval for Network-Validated Contact Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing caller identification systems, particularly in network-enabled telephony devices, often rely on untrusted or unreliable sources for caller information, leading to potential inaccuracies and the inability to prevent unwanted solicitations or fraudulent calls.
Innovation Solution
A computing device integrates an operating system-level network retrieval component that accesses a trusted and authoritative contact information service to validate and display caller or sender information, ensuring authenticity and minimizing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If caller information is retrieved from locally stored contact information or untrusted network sources, then the device can display caller identification, but the accuracy and reliability of the caller information cannot be ensured
Solution Approach 1:
The patent introduces a network authority as an intermediary component that acts as a trusted mediator between the computing device and caller information sources. This network authority validates and authenticates caller information before it is displayed to the user, ensuring reliability without requiring the device itself to implement complex verification mechanisms. The network authority serves as a centralized trust anchor that simplifies the overall system architecture while maintaining high information accuracy.
2Reliability
If caller information is validated through a network authority, then the authenticity of caller information is ensured, but additional network communication time is required
Solution Approach 1:
The system performs preliminary actions by pre-establishing trust relationships and validation rules with the network authority before actual caller identification is needed. The network authority maintains pre-validated databases of legitimate caller information and authentication credentials, allowing rapid verification during incoming calls. This preliminary preparation minimizes the time required during actual caller identification events while ensuring thorough validation.
3Device complexity
If conventional caller identification methods are used without a network authority, then the system is simpler to implement, but the system cannot prevent unauthorized alteration of caller information
Solution Approach 1:
The network authority acts as a trusted intermediary that mediates all caller information transactions. It signs and validates caller information using cryptographic mechanisms, creating an immutable chain of trust. This intermediary approach prevents unauthorized alteration because any modification to validated caller information would break the cryptographic signature, making tampering detectable. The mediation layer adds security without significantly increasing device-side complexity.
4Reliability
If a network authority is implemented to validate caller information, then fraudulent calls can be prevented, but the device requires additional network connectivity and communication protocols
Solution Approach 1:
The patent extracts the complex fraud prevention and validation logic from the individual computing devices and consolidates it into a centralized network authority. This extraction allows individual devices to have minimal network dependencies - they only need to communicate basic caller identification requests and receive validated responses. The heavy lifting of fraud prevention, database maintenance, and protocol management is taken out and handled by the network authority, reducing the network dependency burden on end devices while maintaining strong fraud prevention capabilities.
Data Source
AI summary
A contact information system provides an independent network authority for providing contact information in connection with incoming calls or messages. The contact information system utilizes a database of communication identifiers to provide contact information for end user devices that receive incoming communications which specify communication identifiers that are stored in the database.
