The present invention encrypts authentication information into an image, document or recording. Briefly described, in architecture, one embodiment is a method comprising generating the original work; generating authentication data when the original work is generated, the authentication data comprising at least location information identifying the location where the original work is generated, the location information provided by a received signal from a remote device, date and time information identifying when the original work is generated, the date and time information provided by a received signal from a remote device, and biometric information identifying an originator of the original work; and encrypting the original work with the authentication data using a secret private key when original work is generated.

Therefore, having thus described the invention, at least the following is claimed: 1. A method for encrypting authentication information into an original work, the method comprising:generating the original work, the original work comprising an image, document, or audio recording;generating authentication data when the original work is generated, the authentication data comprising at least:information corresponding to a background noise that is detected when the original work is generated;location information identifying a location where the original work is generated, the location information provided by a received signal from a remote device, such that the information corresponding to the background noise is part of the authentication data in that the information corresponding to the background noise provides evidence that the location information is correct;date and time information identifying when the original work is generated, the date and time information provided by the received signal from the remote device; andbiometric information identifying an originator of the original work;generating an encryption key used to encrypt the authentication information into the original work;encrypting the original work with the authentication data using the encryption key when the original work is generated; anddestroying the generated encryption key after the step of encryption is completed.
