A method includes generating (202) data with an imaging system (101, fig 1A) in response to a request (200, 300, 400, 500) from an information source (100, fig 1A) and decrypting (212) encrypted information received from the information source, using the imaging system and at least part of the data, to form decrypted information. In addition, the method includes forming a second hash (214) from the decrypted information using the imaging system. Furthermore, the method includes forming an image (218) on media using the decrypted information if the second hash equals a first hash (216B) received from the information source.
