Alien Number Caller ID Verification With Secret-Code Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in telecommunications is verifying the legitimacy of an entity's claim to use an 'alien' telephone number as a caller ID number, particularly when the number is managed by a different carrier than the one handling the outbound call.
Innovation Solution
A method is provided that allows carriers to verify an entity's right to use an 'alien' telephone number as a caller ID by initiating a verification process during device configuration. This involves generating a secret code, placing an outbound call to the alien number, and verifying the code provided by the recipient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a carrier allows use of an alien telephone number as caller ID without verification, then ease of operation is improved, but reliability deteriorates due to potential spoofing and fraudulent activities
Solution Approach 1:
The patent implements preliminary verification action by requiring carriers to verify authority over alien telephone numbers before allowing their use as caller ID. The verification process includes checking whether the carrier has the right to assign the number and confirming the user's authority to use it, which prevents fraudulent use before calls are made.
Solution Approach 2:
The patent introduces an intermediary verification mechanism where the carrier acts as a mediator between the user and the alien telephone number. The carrier receives verification requests, checks authority through established procedures, and only then permits the caller ID configuration, thereby mediating the trust relationship between unrelated carriers and users.
2Reliability
If a carrier implements verification of alien telephone numbers, then reliability is improved, but device complexity increases due to additional verification steps
Solution Approach 1:
The patent segments the verification process into distinct components: (1) receiving the alien telephone number from the user, (2) determining whether the carrier has authority over the number, (3) verifying user authority to use the number, and (4) permitting or denying configuration. This segmentation makes the complex verification process more manageable and implementable.
Solution Approach 2:
The verification steps are performed preliminarily during device configuration or caller ID setup, before actual calling operations. This preliminary action ensures reliability is established upfront, and the complexity is contained to the configuration phase rather than affecting ongoing call operations.
3Reliability
If standardized verification methods are implemented for alien numbers, then reliability is improved, but ease of manufacture deteriorates due to implementation complexity
Solution Approach 1:
The patent provides a universal verification framework that can be applied by any carrier regardless of which carrier manages the alien telephone number. The standardized approach allows the same verification procedures to work across different carrier relationships, making the system multi-functional and broadly applicable throughout the telecommunications industry.
Solution Approach 2:
The patent changes the verification parameter from simple number assignment to authority verification. By shifting the verification focus to whether the carrier has the right to assign and the user has authority to use the alien number, the system achieves standardized reliability across different carrier scenarios while providing clear implementation criteria.

AI summary
The present invention relates to techniques for verifying “alien” telephone numbers for use as caller ID numbers. The system provides a configuration portal for administrative users to establish caller ID settings, including the option to replace a default telephone number assigned to a user/device with an alternative, alien number. A verification process involves generating a secret code, which is then communicated to a designated individual at the alien number through an outbound call. The individual confirms control by providing the secret code. Alternatively, an API request is made to a verification service. The system supports various attestation methods, including SIP protocols, SHAKEN framework, and delegated certificates, to convey the authentication status to carriers handling the call routing. This ensures the integrity of caller identification and prevents caller ID spoofing, enhancing trust and security in telecommunication networks.
