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.
