Abstract: A method, system, and computer program product for generating and displaying comprehensive transaction information is disclosed. Operands including transaction-specific details from an electronic receipt and a pre-shared salt are hashed to produce a unique purchase identifier (PID). A user may submit the electronic receipt to a transaction recorder who also possesses the pre-shared salt. The transaction recorder may create a duplicate of the PID using the electronic receipt and the pre-shared salt. The duplicate PID may be associated with transaction entry stored in a transaction database.
