Communication Filtering via Identity Verification and Ring Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions fail to effectively filter out unwanted Ping Call communications, which clutter called parties' missed communications logs and can be malicious, leading to user dissatisfaction and potential fraud, with existing methods either blocking or forwarding such calls without adequate filtering.
Innovation Solution
A method and device that verify the difference between certified and uncertified calling identities, implement a waiting period corresponding to a ring duration, and present the communication only after this period if no end message is detected, allowing for anonymization of the communication before the waiting period expires, thus alerting the called device to potential unwanted calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the original communication is presented to the called device immediately, then the called device can respond quickly to legitimate calls, but unwanted Ping Call communications are also presented causing clutter and potential fraud
Solution Approach 1:
The system performs preliminary verification of calling identities and activates a waiting period before presenting the communication to the called device. This preliminary action allows the system to detect and filter unwanted Ping Calls by checking whether the communication ends before the waiting period expires, thereby improving filtering accuracy without significantly impacting legitimate call handling.
2Reliability
If a waiting period is implemented to filter unwanted calls, then filtering accuracy improves, but the response time to legitimate calls increases
Solution Approach 1:
The system applies a waiting period selectively rather than universally. It verifies whether the uncertified and certified calling identities differ before activating the waiting period, thereby applying the filtering action only when there is suspicion of unwanted calls. This partial application maintains high unwanted call detection accuracy while minimizing impact on legitimate call handling efficiency.
Solution Approach 2:
The system dynamically adjusts its behavior based on the verification result. When the uncertified and certified identities are the same, the communication is presented immediately without waiting. When they differ, the waiting period is activated. This dynamic approach optimizes both unwanted call detection and call handling efficiency by adapting the filtering intensity to the specific situation.
3Reliability
If certified and uncertified calling identities are verified, then fraudulent calls can be detected, but the device complexity increases
Solution Approach 1:
The system introduces an intermediary verification step that compares the uncertified and certified calling identities without requiring complex fraud analysis. This intermediary comparison acts as a simple yet effective filter, detecting potential fraud by identifying identity discrepancies while maintaining relatively simple device complexity through the use of a straightforward verification mechanism.

AI summary
The communication, termed communication of origin, being generated by a device calling a called device and identified by an uncertified calling identity and by at least one certified calling identity, the method comprising: a step of verifying a condition satisfied if the uncertified calling identity and the at least one certified calling identity are different; and if the condition is satisfied, a step of detecting an expiry of a waiting time consecutive to the verification, this time corresponding to the duration of at least one ring of the called device; following the step of detecting the expiry and in the absence of detecting a message identifying the end of the communication of origin, a step of presenting the communication of origin to the called device with at least one calling identity among the uncertified calling identity and the at least one certified calling identity, the communication of origin not being presented to the called device before the detection step; following the verification step, saving at least one calling identity among said uncertified calling identity and said at least one certified calling identity; and presenting to said called device, before said detection of the expiry of said waiting time, a provisional anonymized communication corresponding to said communication of origin but in which none of said certified and uncertified calling identities is presented, at least one of said saved calling identities being replaced by a masked calling identity of the same time, or presented as an unavailable identity of the same type.
