Abstract
A computer-implemented method of generating a secondary transaction identifier of a target transaction which enables a querying user to determine whether the target transaction comprises a candidate data field. The method comprises identifying a set of data fields of the target transaction, each data field comprising respective data of the transaction; and generating a transaction hash tree. Each data field is hashed to generate a respective one of a plurality of leaf hashes of the transaction hash tree. The root hash of the transaction hash tree comprises the secondary transaction identifier.
