Portable Verification Context for Early Fraud Request Rejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing verification systems consume significant processing, memory, and network resources due to repeated verification procedures across different platforms, services, and devices, and are vulnerable to malicious attacks that exhaust resources before identifying fraudulent requests.
Innovation Solution
Implementing a portable verification context tied to a unique identifier, which is generated during registration, allowing verification services to be performed outside the service layer, thus reducing resource consumption and rejecting fraudulent requests early in the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If verification procedures are performed repeatedly across different platforms and services, then verification accuracy is maintained, but processing resources and network bandwidth are significantly consumed
Solution Approach 1:
The system performs verification in advance during the registration procedure, generating a verification context that is stored and reused for subsequent service calls. This preliminary verification action eliminates the need for repeated verification procedures, thereby maintaining verification accuracy while significantly reducing processing resource consumption.
Solution Approach 2:
The system creates a verification context that serves as a copy or representation of the verified identity information. This verification context can be reused across multiple service calls and platforms without requiring the original verification data to be re-processed, thus preserving verification reliability while minimizing resource usage.
2Reliability
If verification services are performed at the service layer, then comprehensive verification is achieved, but network resources and processing time are increased
Solution Approach 1:
The verification context is generated and stored during the registration procedure before actual service calls are made. This preliminary action allows subsequent service calls to use the pre-computed verification context, eliminating the need for time-consuming verification processes at the service layer while maintaining verification completeness.
Solution Approach 2:
The verification process is segmented into two parts: (1) the initial verification and context generation performed during registration, and (2) the rapid context validation performed during service calls. This segmentation moves the computationally intensive verification work away from the service layer, reducing verification time while maintaining completeness.
3Reliability
If traditional verification systems process all service calls through the service layer, then security is maintained, but system performance and resource efficiency deteriorate
Solution Approach 1:
The verification functionality is extracted from the service layer and implemented as a separate verification service that operates independently. This extraction allows the majority of service calls to bypass the service layer and use the efficient verification context validation, maintaining security through the verification service while significantly improving overall system performance.
Solution Approach 2:
The verification context acts as an intermediary between the service calls and the verification service. It enables rapid validation without requiring full service layer processing, thus maintaining security through the verification service while improving system performance by reducing the number of calls that need complete service layer treatment.

AI summary
In some implementations, a device may obtain verification information associated with an account based on a registration procedure associated with a service. The device may generate a verification context associated with the account based on the verification information, wherein the verification context is an object used to verify access attempts to the service. The device may store the verification context in connection with a unique identifier. The device may obtain a request to access the service, wherein the request is associated with the account, and wherein the request indicates an identifier. The device may perform a verification service associated with the request prior to passing the request to a service layer associated with the service, wherein the verification service includes verifying the request based on whether the identifier indicated by the request matches the unique identifier.
