Abstract
An identity chaining fraud detection method that allows each current transaction to be linked to other transactions through commonly shared identities. Over a period of time the links create a chain of associated transactions which can be analyzed to determine if identity variances occur, which indicates that fraud is detected. Additionally, if a specific identity is detected as being fraudulent, that identity can be tagged as fraudulent and can be referenced by a plurality of other merchant transaction chains to determine fraud.
Claims20
A method comprising:
- processing, by a chaining engine executing on a central server computer, transaction data from a plurality of merchant computers to identify a plurality of transactions;
- generating, by the chaining engine, a dynamic chain of linked transactions based on shared identities in transaction data of the plurality of transactions, wherein the dynamic chain of linked transactions is configured to be updated by adding one or more additional transactions in real-time;
- receiving, at the central server computer from a first merchant computer, first transaction data of a first transaction, wherein the first transaction data includes a first plurality of identities;
- updating in real-time, by the chaining engine, the dynamic chain of linked transactions by:
- linking, in real-time, the first transaction to at least one of the plurality of transactions previously linked to each other,
- wherein in the dynamic chain of linked transactions the first transaction is linked to a second transaction through a first identity that is included in the first plurality of identities associated with the first transaction and a second plurality of identities associated with the second transaction;
- comparing, in real-time and by the chaining engine, each identity stored in the dynamic chain of linked transactions to a negative list database of identities associated with one or more fraudulent activities to determine whether the first transaction is fraudulent;
- matching, by the chaining engine based on the dynamic chain of linked transactions, a second identity from the second plurality of identities associated with the second transaction to an identity from the negative list database of identities, wherein the second identity is not included in the first plurality of identities associated with the first transaction, the second transaction is linked to the first transaction in the dynamic chain of linked transactions;
- based on the matching:
- identifying, by the central server computer, the first transaction as a fraudulent transaction;
- generating, by the central server computer, a first message indicating a first fraud alert for the first transaction;
- sending, by the central server computer, the first message to the first merchant computer indicating the first fraud alert for the first transaction;
- and
- updating, by the central server computer, the negative list database of identities based on the dynamic chain of linked transactions to include a third identity from the first plurality of identities, the third identity not previously included in the negative list database of identities.

A system comprising:
- a central server computer that includes a computer readable medium and processor, in communication with a plurality of merchant computers,
- a chaining engine, executing on the central server computer,
- wherein the central server computer, in connection with the chaining engine, is configured to perform:
- processing transaction data from a plurality of merchant computers to identify a plurality of transactions;
- generating a dynamic chain of linked transactions based on shared identities in transaction data of the plurality of transactions, wherein the dynamic chain of linked transactions is configured to be updated by adding one or more additional transactions in real-time;
- receiving, from a first merchant computer, first transaction data of a first transaction, wherein the first transaction data includes a first plurality of identities;
- updating in real-time the dynamic chain of linked transactions by:
- linking, in real-time, the first transaction to at least one of the plurality of transactions previously linked to each other,
- wherein in the dynamic chain of linked transactions the first transaction is linked to a second transaction through a first identity that is included in the first plurality of identities associated with the first transaction and a second plurality of identities associated with the second transaction;
- comparing, in real-time, each identity stored in the dynamic chain of linked transactions to a negative list database of identities associated with one or more fraudulent activities to determine whether the first transaction is fraudulent;
- matching, based on the dynamic chain of linked transactions, a second identity from the second plurality of identities associated with the second transaction to an identity from the negative list database of identities, wherein the second identity is not included in the first plurality of identities associated with the first transaction, the second transaction is linked to the first transaction in the dynamic chain of linked transactions;
- based on the matching:
- identifying the first transaction as a fraudulent transaction;
- generating a first message indicating a first fraud alert for the first transaction;
- sending the first message to the first merchant computer indicating the first fraud alert for the first transaction;
- and
- updating the negative list database of identities based on the dynamic chain of linked transactions to include a third identity from the first plurality of identities, the third identity not previously included in the negative list database of identities.
