ABSTRACT:
To propose an encryption device and encryption method capable of improving reliability of an encryption function. An element-specific parameter unique to a solid imaging element is created based on a uniform image signal S2output from the solid imaging element as a result of imaging a uniform imaging target with the imaging unit11, and identification information D1is encrypted with encryption key information D2extracted from this element-specific parameter, thereby being capable of ensuring confidentiality of the identification information D1and thus improving reliability of an encryption function.
