ID Header Translation for Robocall Traffic Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Malicious users generate auto-initiated communication requests, such as robocalls and spam calls, that increase network traffic and attempt to steal information/resources, with existing systems struggling to effectively identify and mitigate these threats.
Innovation Solution
Systems and methods dynamically modify communication operations by spoofing and decoding headers, identifying auto-initiated requests, and generating error logs to reduce network traffic and prevent unauthorized access, using a server communicatively coupled to networks and user equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If auto-initiated communication requests are allowed to pass through the network, then network traffic volume increases, but network security and resource protection deteriorate
Solution Approach 1:
The patent introduces an intermediary system that sits between external networks and the telephony network. This intermediary dynamically modifies communication operations by spoofing information, decoding and rearranging header data, and encoding it to simulate spoofed communications for testing. This intermediary layer filters and transforms incoming calls, allowing legitimate traffic while blocking malicious auto-initiated requests before they reach the core network
Solution Approach 2:
The system dynamically changes parameters of communication operations by modifying header information. It decodes header data, rearranges it, and re-encodes it to create modified communication operations. These parameter changes enable the system to identify and differentiate between legitimate and malicious calls, transforming the communication operations to protect the network
2Difficulty of detecting and measuring
If dynamic modification of communication operations is implemented, then detection capability improves, but processing complexity increases
Solution Approach 1:
The patent segments the header modification process into distinct functional components: decoding the header portion, rearranging the decoded data, and encoding the rearranged data. This segmentation allows each component to be optimized independently and makes the complex detection process more manageable and implementable within existing network infrastructure
3Measurement precision
If spoofed communications are generated for testing, then testing accuracy improves, but processing time increases
Solution Approach 1:
The system performs preliminary actions by dynamically generating spoofed communication operations before they reach the testing system. By pre-modifying the communication operations and creating test scenarios in advance, the system enables the testing system to evaluate detection capabilities accurately without introducing significant processing delays to live traffic
Data Source
AI summary
An apparatus comprises a memory and a processor communicatively coupled to one another. The memory may be configured to store configuration commands configured to trigger one or more encoding operations and one or more decoding operations. The processor may be configured to receive a communication request comprising communication information comprising one or more data packets, obtain identity (ID) header information from the one or more data packets, decode at least one portion of the ID header information into decoded ID header information, derive a translation value from the decoded ID header information, and modify the translation value into a modified translation value. Further, the processor is configured to encode the modified translation value into an encoded modified translation value, reconstruct the ID header information based on the encoded modified translation value, and forward the communication request comprising a reconstructed version of the ID header information to a testing system.
