Abstract
Embodiments of the present invention provide a method and system for authentication. In one embodiment, a first identifier associated with an item to be authenticated may be received. A first decryption key associated with the item may also be received. The first identifier may be decrypted using the first decryption key to generate a second identifier. The contents of an authentication database may be searched to find a match for the second identifier. If a match for the second identifier is found in the authentication database, the item may be confirmed as authentic. In embodiments of the present invention, the item may be a lottery ticket, a document, a receipt, a ticket, a credit card, etc.

A lottery ticket, comprising:
- a public encrypted ticket identifier readable from the lottery ticket and embodied in a bar code;
- and a public decryption key readable from the lottery ticket, the public decryption key configured to decrypt the encrypted ticket identifier;
- wherein both the public encrypted ticket identifier and the public decryption key are provided on the lottery ticket prior to the lottery ticket being distributed to a player and
- the public decryption key is configured to decrypt the encrypted ticket identifier to generate an authentication identifier and
- the authentication identifier is maintained separately in a lottery ticket authentication database of a lottery ticket authentication system to prevent an insider from determining the public identifier for the ticket.
A method of authenticating a ticket comprising:
- receiving an authentication request from an input device;
- wherein the authentication request includes a public lottery ticket identifier;
- responsive to receiving the authentication request, decrypting the public lottery ticket identifier using the corresponding lottery ticket decryption key to generate a third identifier;
- responsive to decrypting the public lottery ticket identifier, searching the contents of a lottery ticket authentication database to find a match for the third identifier;
- and
- responsive to finding a match for the third identifier in the lottery ticket authentication database, validating the lottery ticket.
A system comprising:
- an interface to receive a public identifier readable from a ticket and provided on the ticket prior to the distribution of the ticket;
- a decryption device to decrypt the public identifier using a decryption key to generate a second identifier, wherein the second identifier is maintained separately in an authentication database of an authentication system to prevent an insider from determining the public identifier for the ticket;
- a comparator to search the contents of the authentication database to find a match for the second identifier, wherein the interface is configured to confirm that the ticket is authentic, responsive to finding a match for the second identifier in the authentication database.
