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 1):
A solid-state imaging device comprising\n 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 key generation-use data, at least one of fluctuation information of the 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 for making the unique key difficult to break as tamper resistance enhancement processing, and wherein the tamper resistance enhancement processing part in the key generation part includes an averaging processing part for performing averaging processing on a plurality of pixels of the key generation-use data.
