Definitions
- the present invention concerns digital cameras and pertains particularly to authentication and verification within a digital camera architecture.
- an enhanced digital camera includes a non-volatile memory in which is stored a security value used to produce digital signatures for photographs.
- a processor within the enhanced digital camera processes a photograph by hashing digital data for the photograph to produce a hash digest.
- the processor then performs a digital signature function on the hash digest using the security value in order to produce a digital signature for the photograph.
- the processor hashes a serial number for the camera and a date and time stamp along with the digital data for the photograph to produce the hash digest.
- the security value is, for example, a unique private key that is part of a private/public key pair.
- the non-volatile memory and the processor are within a secure integrated circuit and the processor generates the private/public key pair.
- the non-volatile memory is, for example, a one-time programmable memory.
- the public key is, for example, stored in a third party database and may be accessed (using the serial number for the enhanced digital camera) when it is necessary to authenticate a photograph taken by the enhanced digital camera.
- the digital signature is stored with the digital data for the photograph.
- digital data for the photograph is hashed to produce a computed hash digest.
- the serial number for the camera and the date and time stamp are hashed along with the digital data for the photograph.
- the public key for the enhanced digital camera is used to perform a digital signature function on the digital signature for the photograph in order to produce an extracted hash digest.
- the computed hash digest is compared with the extracted hash digest to determine whether the photograph is authentic and unaltered.
- the authentication and integrity verification utilized by the enhanced digital camera architecture of the present invention provides the necessary functionality to authenticate photographs and to detect alterations.
- Figure 1 is a simplified block diagram of a digital camera architecture that incorporates authentication and verification in accordance with a preferred embodiment of the present invention.
