1. A digital camera comprising:
a processor; and
a computer readable storage medium coupled to the processor, the computer readable storage medium comprising computer readable program code that when executed by the processor causes the processor to perform operations comprising:
generating a first checksum of pixels that make up a photograph taken with a digital camera;
storing the first checksum it metadata associated with the photograph;
generating a second checksum of the first checksum and global positioning system information associated with the photograph, wherein the second checksum is generated after the first checksum; and
encrypting the second checksum using a private key associated with the digital camera to provide an encrypted checksum;
wherein the global positioning system is a spaced-based radio navigation system.
