Claim One:
1. A computer-implemented method for removing personally identifiable data comprising: receiving, by a computer of a fraud detection system, financial transaction data associated with one or more financial transactions from a server of a first financial institution, wherein the server of the first financial institution records the financial transaction data in a non-transitory memory; identifying, by the computer of the fraud detection system, personally identifiable data within the financial transaction data received from the first financial institution; generating, by the computer of the fraud detection system, a first set of hashed data of the personally identifiable data by applying a hashing algorithm using a first hash key to the personally identifiable data; generating, by the computer of the fraud detection system, a first reverse hashing map by creating a table including information used for converting the first set of hashed data back into the personally identifiable data received from the first financial institution; transmitting, by the computer of the fraud detection system, the first reverse hashing map to the server of the first financial institution; deleting, by the computer of the fraud detection system, the first reverse hashing map and the first hash key; performing, by the computer of the fraud detection system, fraud analysis using the first set of hashed data; generating, by the computer of the fraud detection system, a report containing the likelihood one or more transactions recorded in the financial transaction data are associated with fraud, wherein the report contains first set of hashed data instead of the personally identifiable data; transmitting, by the computer of the fraud detection system, the report to the server of the first financial institution; and retrieving, by the server of the first financial institution, the personally identifiable data from the report using the first reverse hashing map and the first set of hashed data.
