Abstract
A system is provided in which document imaging equipment is used to acquire a document image from a printed document. The document image may be processed using an optical character recognition application implemented on the document imaging equipment. A user may supply identifier information. The identifier information may be used in constructing an identity-based-encryption (IBE) public key. Identity-based-encryption public parameter information and the IBE public key may be used in encrypting the document image. The IBE-encrypted document image may be stored in storage or sent to a recipient in a message. A user receiving the IBE-encrypted document image may obtain an IBE private key from a key server that is used in decrypting the IBE-encrypted document.
