Abstract: A method and system for generation of ticket security codes is provided. The method includes generating, by a host computing system, a lottery transaction authentication code for each transaction, generating an additional security code for the transaction, and including the generated additional security code on a lottery receipt for the transaction. The additional security code includes information that cannot be reproduced in the host computing system without access to the lottery ticket receipt and allows verification of critical data for the transaction.

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.

Abstract: A method and system is provided for managing the outcomes of games of chance while maintaining the game's integrity.

Abstract: The present disclosure provides a method for protecting the “identity” of random numbers used in multiplayer games, which prevents fraud related to access to random game elements by insiders. The method enables a distribution of random numbers by a game server in a way that the game server does not know the “identity” of random numbers but the game server may independently verify these random numbers. The method includes receiving transformation information, generating random numbers, transforming random numbers according to the transformation information, sending the transformed random numbers to a game server, securing, via the game server, the transformed random numbers, sending the transformed random numbers from the game server to a remote client, and transforming the transformed random numbers to recreate the generated random numbers.

Abstract: The present invention is a method and system for selling game of chance tickets at a point of sale cash register. The invention can be used for both lottery and other social games of chance tickets. An actual game ticket may be preprinted by the commercial printer, printed in the in-store kiosk, self-service terminal or on the standard gaming terminal. These preprinted tickets are not eligible to win prizes unless activated at the cash register. Tickets have a barcode or other means readable by a cash register or other equipment. The ticket is read at the cash register and activated. Acknowledgement of activation of the ticket is then printed on the cash register receipt.

Abstract: A system and method for generation of unpredictable and auditable random numbers includes a host computer, a digital signature server and a verification device. The host computer provides data to the digital signature server; obtains digital signature for this data; uses elements of this signature for random numbers generation; logs relevant data for audit. The verification device uses logged data for auditing of the random number generation process. This invention can be applied in gaming and gambling industries where the random numbers are used for generation of game/play elements and of winning numbers elements. The game/play elements and winning numbers elements generated using this invention can be audited.
