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.
