Examples include a system that identifies relationships between records. Data corresponding to a plurality of records is accessed, wherein the data is related to different consumer cards. Data fields of the data are compared to identify one or more matches between the plurality of records. A plurality of relationships between the plurality of records is determined based at least on the identified one or more matches. A score is generated based on the determined plurality of relationships. The system produces risk assessment data with enhanced reliability and greater accuracy while reducing system resource usage.

Methods and server systems for categorizing payment cards for fraud prevention are described herein. Method performed by a server system includes accessing a card candidate set including relevant payment card(s), each payment card of the relevant payment card(s) being associated with multiple features. Method includes segregating the features into a set of risk-related features and a set of transactional features. Method further includes generating, by Machine Learning (ML) model(s), a riskiness score for each payment card based on the set of risk-related features. Method includes performing for each payment card: assigning a risk category based on the riskiness score and risk categorization criteria, and assigning a transactional category based on the set of transactional features and transaction behavior criteria. Method includes generating a recommendation message for an issuer based on the risk category and the transactional category.

A method of protecting a generative artificial intelligence (AI) platform can include receiving, at a security interceptor, a plurality of communications from the generative AI platform to one or more sources over a network, wherein each communication of the plurality of communications comprises a source-specific safe-for-AI token (SFAI token) associated with a particular source of the one or more sources appended thereto; checking, by the security interceptor, a safety level of each source-specific SFAI token received with the plurality of communications; for each source-specific SFAI token having a safety level indicating a permitted source, permitting a corresponding communication comprising that source-specific SFAI token to be transmitted to the particular source associated therewith; and for any communication of the plurality of communications comprising a corresponding source-specific SFAI token having a safety level indicating a proscribed source, blocking that communication to be transmitted to the particular source associated therewith.
