Abstract
A solid-state imaging device includes a pixel part, a reading part for reading a pixel signal from the pixel part and a response data generating part including a fuzzy extractor. The response data generating part generates response data including a unique key in association with at least one selected from among variation information of pixels and variation information of the reading part. The response data generating part generates, when regenerating a key, a unique key using helper data acquired in generation of an initial key, variation information acquired in the regeneration of the key, and reliability information determined based on the variation information acquired in the regeneration of the key.
