摘要：
A method is disclosed. The method includes generating an obfuscated portion using a dynamic cryptogram unique to a transaction, where the dynamic cryptogram is determined using a uniquely derived key. The method also includes replacing a middle portion of the account identifier with the obfuscated portion to form an obfuscated account identifier.
