Telecom Identity Spoofing Detection via Intermediary Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies are inadequate in preventing identity theft, particularly in IP communication systems, where unscrupulous individuals can easily spoof telephone numbers or email addresses, leading to serious consequences for subscribers.
Innovation Solution
A method and device for managing telecommunications domains to verify the authenticity of connection data by searching databases associated with both the originating and destination domains, rejecting communications if the data is invalid, thereby preventing number spoofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If caller ID service is provided to display calling number, then subscribers can see caller information and identify contacts, but this enables identity theft and number spoofing by allowing imposters to present false calling numbers
Solution Approach 1:
A verification system acts as an intermediary between the calling and called parties. The system receives the calling number from the caller, verifies its authenticity against a database of legitimate numbers, and only allows the call to proceed if verification succeeds. This intermediary verification process prevents imposters from successfully spoofing numbers while maintaining the caller ID service functionality.
Solution Approach 2:
The verification of the calling number is performed in advance, before the call is established. The system pre-validators the authenticity of calling numbers by checking them against a database of legitimate numbers assigned to subscribers. This preliminary verification action prevents fraudulent calls from being established in the first place, rather than detecting and blocking them after establishment.
2Adaptability or versatility
If number spoofing is allowed in IP communication systems, then users can freely configure calling numbers for various purposes, but this enables fraud and serious consequences for subscribers whose numbers are spoofed
Solution Approach 1:
The verification system serves as an intermediary that mediates between the user's desire to configure calling numbers and the need to prevent fraud. The system accepts number configuration requests but intercepts and verifies the calling number before allowing communication establishment. This intermediary control maintains user adaptability while preventing fraudulent use through automated verification against legitimate number databases.
3Productivity
If third party numbers are positioned in calling number field to circumvent hidden number filtering, then callers can reach victims who block direct calls, but this encourages answer by imposters and facilitates identity theft
Solution Approach 1:
The verification system acts as an intermediary that blocks the technique of using third-party numbers to circumvent call filtering. By verifying that the calling number matches the actual subscriber initiating the call, the system prevents imposters from using victim's numbers or third-party numbers to trick callers into answering. This maintains legitimate call delivery while blocking fraudulent workarounds.

AI summary
The invention relates, according to a first aspect, to a method of control, by a piece of management equipment of a first telecommunication domain, of the authenticity of at least one relationship datum relating to the initiator of a communication and indicated in a message for establishing the communication originating from a second telecommunication domain and destined for the first telecommunication domain, characterized in that it comprises, upon receipt of the message by the management equipment, steps of extracting (200) the at least one relationship datum from the message; of searching (201) for the at least one relationship datum in at least one database of the relationship data associated with the first domain, and of rejecting (203) the communication when an occurrence of the at least one relationship datum is found in the database.
