Apparatus for authenticated recording and method therefor
First Claim
1. An apparatus for certifying digital recordings comprising:
- a data converter for generating a first output file having a predetermined data format in response to an input signal from a transducer;
an encryption unit operable for receiving the first output file and generating a second, enciphered, output file, wherein the encryption unit enciphers the first output file using a secret key corresponding to a recording apparatus; and
a storage device for storing the second output file.

Abstract
An apparatus, system and method for certifying photographs, videographs and audio recordings are implemented. A unique private encryption key may be associated with the recording device, which, for video may be a digital camera, or for audio recordings, a digital audio recording device. The digital photographic, videographic or audio data may then be encrypted by the recording device in essentially real-time and stored in encrypted form. The rendering of the digital photograph, videograph or digital audio signal into a perceptible form, may be effected by recovery of the corresponding “public” decryption key from the manufacturer of the recording device, and the stored encrypted data may be decrypted after retrieval from the storage device. The decryption key may, for example, be made available by the manufacturer on a web site.

12. A method for certifying digital recordings comprising:
-
generating a first output file having a preselected file format in response to a signal from a transducer;
encrypting the first output file to form a second, enciphered, output file, wherein the encryption is generated using a private key corresponding to a recording device for performing the generating and encrypting steps; and
storing the second output file. - View Dependent Claims (13, 14, 15, 16, 17)

18. A data processing system for reproducing a recording comprising:
-
a central processing unit (CPU); and
a memory for storing a program of instructions and data for the CPU; and
a storage interface unit adapted for receiving a stored, enciphered recording file, wherein the program of instructions includes instructions for retrieving a public key corresponding to a recording device generating the recording file and instructions for decrypting the enciphered recording file using the public key. - View Dependent Claims (20)
