Authentication Clearinghouse for Password Fraud Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network technologies lack effective mechanisms to detect and respond to compromised authentication information in real-time, leaving users vulnerable to malicious attacks and failing to provide adequate security measures to protect personal and monetary information.
Innovation Solution
Implementing a password fraud detection system that monitors and compares password frequency of use across accounts, flagging potentially compromised accounts and requiring additional authentication measures, such as CAPTCHA or security questions, to prevent unauthorized access, while maintaining separate data stores for frequency and password data to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security measures are used to protect consumer information, then basic security is provided, but real-time detection and response to compromised authentication information is lacking
Solution Approach 1:
The system performs preliminary actions by maintaining a proactive watch list of compromised authentication information and proactively comparing user credentials against this list before allowing account access, rather than waiting for security breaches to occur
Solution Approach 2:
The system implements continuous feedback loops by monitoring authentication attempts, updating the watch list with newly compromised credentials, and immediately using this updated information to protect against future attacks, creating a dynamic security response mechanism
2Reliability
If password frequency monitoring is implemented across accounts, then compromised accounts can be identified, but system complexity increases
Solution Approach 1:
The system segments authentication security by maintaining separate data stores for password information and frequency-of-use information, allowing independent management and analysis of each data type while reducing the complexity of managing a single monolithic authentication system
Solution Approach 2:
The system introduces an intermediary authentication information clearinghouse that acts as a mediator between individual account systems, collecting and analyzing password frequency data from multiple sources without requiring direct integration between the accounts themselves
3Object-affected harmful factors
If additional authentication measures are required for flagged accounts, then unauthorized access is prevented, but user convenience decreases
Solution Approach 1:
The system applies partial authentication measures by requiring additional verification steps only for accounts flagged as potentially compromised, while allowing standard authentication for accounts that pass security checks, thus balancing security with user convenience

AI summary
Techniques for maintaining potentially compromised authentication information for a plurality of accounts may be provided. An individual piece of authentication information may be associated with one or more tags that indicate access rights with respect to requestors that also provide and maintain other potentially compromised authentication information. A subset of the potentially compromised authentication information may be determined based on the one or more tags in response to a request from a requestor for the potentially compromised authentication information. In an embodiment, the subset of the potentially compromised authentication information may be provided to the requestor.
