Abstract
Providing tamper-evident transaction data for transactions relating to a draw or game event such as a lottery or other game of chance or skill. The transactions, individually, as a whole draw or event file, or in batches, are digitally time-stamped using a cryptographic device to create digital signatures. The resulting, signed, transaction file is capable of subsequent verification to enable detection of alteration of the transaction data and the time it was processed. The efficient time-stamping occurs quickly, does not require custom software on the gaming system, and ensures transaction integrity.
