Abstract:
A solid-state imaging device having a pixel portion in which a plurality of pixels each including a photodiode are arranged in rows and columns, a reading part for reading pixel signals from the pixel portion, and a key generation part which generates a unique key by using, as the key generation-use data, at least one of fluctuation information of pixels and fluctuation information of the reading part, wherein the key generation part includes a tamper resistance enhancement processing part for processing the key generation-use data to enhance the tamper resistance making it difficult to break the unique key as tamper resistance enhancement processing. Due to this, it is possible to generate a unique key having a high confidentiality. Further, it is possible to improve reproducibility and uniqueness of the unique ID, is possible to secure a high tamper resistance of the unique key, and consequently is possible to reliably prevent tampering and forgery of an image.

Claim (Index 4):
The solid-state imaging device as set forth in  claim 2 , wherein the tamper resistance enhancement processing part in the key generation part includes a sorting part for sorting the output data of the judgment part.
