Abstract:
1. A method for obfuscating an account identifier comprising: identifying, by a computing device, a first end portion of the account identifier; identifying, by the computing device, a middle portion of the account identifier, wherein the middle portion of the account identifier excludes the first end portion of the account identifier and further excludes a second end portion of the account identifier; identifying, by the computing device, the second end portion of the account identifier; creating, by the computing device, a unique derived key using at least a master key, the first end portion of the account identifier, and the second end portion of the account identifier; generating, by the computing device during a financial transaction, a dynamic cryptogram unique to the financial transaction using the created unique derived key; generating, by the computing device, an obfuscated portion of the account identifier using the generated dynamic cryptogram; replacing, by the computing device, the middle portion of the account identifier with the generated obfuscated portion to create an obfuscated account identifier; and transmitting, by the computing device to another device, the created obfuscated account identifier within an account identifier field of a transaction data for the financial transaction.
