Caller ID Customization via Shared Secret Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional caller ID systems fail to accurately identify the actual caller when a call is made from a borrowed device and do not prioritize calls, leading to missed important communications, and lack security features to prevent unauthorized customization by scammers or telemarketers.
Innovation Solution
Implementing a shared secret system between calling and called parties to customize caller ID and prioritize calls, allowing the actual caller to identify themselves and manage their communication device remotely, while preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional caller ID systems are used to display the registered owner's name, then the system is simple and reliable, but the actual caller's identity cannot be identified when using a borrowed device
Solution Approach 1:
The system pre-establishes shared secrets between communicating parties before actual communication occurs. When Party A and Party B communicate, they exchange and store shared secrets in advance, enabling the receiving device to verify and display the actual caller's identity rather than just the registered owner's information.
2Adaptability or versatility
If caller ID customization is allowed for all callers, then callers can accurately identify themselves and prioritize calls, but unauthorized users like scammers can misuse the system
Solution Approach 1:
The system introduces shared secrets as an intermediary verification mechanism between the caller and called party. The receiving device uses the pre-established shared secret to authenticate whether the incoming caller ID customization request is legitimate, thereby allowing authorized customization while blocking unauthorized users like scammers and telemarketers.
3Loss of information
If the system displays only the registered telephone number, then the system is simple and secure, but the receiving party cannot recognize the actual caller and may miss important calls
Solution Approach 1:
The system segments the caller identification process into two parts: the registered device information (telephone number) and the actual user identity (displayed name). By using shared secrets, the system can separately verify and display the actual user's name while maintaining the registered number for authentication purposes, thereby preserving both security and information completeness.

AI summary
Methods, devices, systems and computer program products are described for implementing on a communication device customized caller ID and remote functional management of a communication device via shared secret exchange between calling and called parties. Customized caller ID provides for a calling party to identify themself regardless of the device they are using to place to call. In addition, other remote functional management, such as call priority tagging, provides for the calling party to prioritize the call or otherwise customize a call ID message to the called party. By exchanging shared secrets amongst the calling and called parties, the customized caller ID method and remote functional management are secure, thereby eliminating the likelihood of unauthorized tampering by unknown parties. Shared secret exchange also provides for authorized callers to remotely access and manage the communication device, such as, for example, to remotely lock down or place the communication device in an off state.
