Fraud Detection in Self-Service Terminal

A method, comprising:

• receiving, by a processor integrated within a self-service terminal (SST), a sequence of transaction-related commands during a customer interaction;
• analyzing, by the processor, the sequence of transaction-related commands to detect deviations from expected transaction patterns;
• determining, by the processor, a likelihood of fraudulent activity based on the analyzing of the sequence of transaction-related commands;
• and
• controlling, by the processor, operation of a transaction component of the SST, in response to the determined likelihood of fraudulent activity, wherein the transaction component is selected from a group consisting of a currency dispenser, a card reader, and a receipt printer.

A method, comprising:

• monitoring, by a processor of a self-service terminal (SST), a plurality of transaction events including customer authentication inputs and transaction execution outputs;
• identifying, by the processor, irregular transaction event patterns by comparing the monitored transaction events with a database of known transaction event patterns associated with legitimate transactions;
• inferring, by the processor, potential unauthorized transaction activity based on an identification of irregular transaction event patterns;
• and
• implementing, by the processor, a security protocol that alters transaction processing capabilities of the SST upon inferring the potential unauthorized transaction activity.

A system comprising:

• a self-service terminal (SST) including a user interface for receiving transaction instructions from users and a transaction execution unit for carrying out the transaction instructions;
• a control unit housed within the SST and comprising a processor and a memory, the memory storing instructions that, when executed by the processor, cause the control unit to:
• record transaction instructions and corresponding transaction outcomes to form a transaction record;
• compare the transaction record to a set of predefined criteria indicative of transaction integrity;
• assess transaction risk based on a comparison, wherein the transaction risk is indicative of potential fraudulent activity;
• and
• modify transaction execution parameters of the transaction execution unit based on the assessed transaction risk to mitigate potential fraudulent activity.
