The present invention is directed to a system and method for secure document transmission. A sender selects a portion of an original document containing confidential information using a highlighter, bracketing, underlining, or other identifying marks. The original document is then scanned to generate an electronic version, which is subject to optical character recognition to locate the portions of the document containing confidential information based on the identifying marks. These portions containing confidential information are then encrypted and a hybrid document containing non-encrypted portions and encrypted portions is generated. The hybrid document is then sent to a recipient, along with a decryption key. The hybrid document is then marked by the recipient to designate those areas containing encrypted information. The marked document is then scanned to generate an electronic version, which is analyzed to identify which portions require decryption based on the identifying marks made by the recipient. These portions are decrypted and a complete reproduction of the original document is generated for the recipient.

System and method for encrypting and decrypting document reproductions

A system and method for authenticating document processing transactions wherein the transaction is rejected if the user is not within a selected geographical region. A transaction request is first received representing a request for the completion of a selected transaction associated with a selected user. Preauthorized geographic region data, associated with the selected user, is then received indicating from where the associated user is allowed to request transactions. Location data representing the source of the transaction request is then received and tested against the preauthorized geographic region data. The result of this testing determines whether the requested transaction is authorized.
