Communication Blocking via Sender Trust Challenges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies fail to effectively block unwanted communications, such as fraudulent and unsolicited calls and texts, due to spoofing and lack of active measures from communication platforms, leading to recipients receiving numerous unwanted messages daily.
Innovation Solution
Implementing a system that issues challenges to senders based on trust levels, where communications from low-trust numbers are challenged multiple times, and those failing to respond are temporarily or permanently banned, while high-trust communications are routed directly to recipients without challenge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If communication platforms do not implement active blocking measures, then device complexity remains low, but recipients receive numerous unwanted communications daily
Solution Approach 1:
The system performs preliminary actions by issuing challenges to senders before routing communications to recipients. Trust levels are determined in advance, and senders are challenged multiple times beforehand to verify their legitimacy. This preliminary verification process blocks unwanted communications before they reach recipients, reducing harmful factors while managing system complexity through proactive rather than reactive measures.
2Reliability
If all communications are routed directly without verification, then productivity is high, but fraudulent and unsolicited communications reach recipients
Solution Approach 1:
The system applies local quality by differentiating verification processes based on sender trust levels. High-trust senders receive direct routing without challenges, maintaining high productivity for legitimate communications. Low-trust senders undergo multiple challenges, ensuring reliability for suspicious communications. This localized approach to verification maintains overall system efficiency while improving communication authenticity through targeted validation.
3Reliability
If multiple challenges are issued to all senders, then communication authenticity improves, but time consumption increases
Solution Approach 1:
The system implements partial action by issuing multiple challenges only to low-trust senders rather than all senders. High-trust senders bypass the challenge process entirely, minimizing time loss for legitimate communications. The excessive verification (multiple challenges) is applied selectively only where needed for low-trust senders, achieving high verification accuracy for suspicious communications without unnecessarily delaying normal communication flow.

AI summary
A text communication is received from a telephone number of a sender. The text communication is directed to a recipient. A determination is made as to whether to challenge the sender. Responsive to determining to challenge the sender, a challenge is transmitted to the sender. A determination is made as to whether to route the text communication to the recipient based on whether a successful response to the challenge is received from the sender.
