Abstract

A solid-state image pickup device 10 comprises: a pixel unit 20; a read unit 90 that reads pixel signals from the pixel unit 20; and a response data generation unit 80 that includes a fuzzy extractorand that generates response-data containing a unique key associated with pixels and / or read unit variation-information. When regenerating a key, the response data generation unit 10 generates a uniquekey using: helper data obtained when initially generating the key; variation information obtained when regenerating the key; and reliability information predicted from the variation information whenregenerating the key. Due to this configuration: it is not necessary to perform multiple instances of counting a response for obtaining reliability information, nor is it necessary to impart reliability to helper data; it is possible to prevent an increase in the data stored in the fuzzy extractor when initially generating a key; and it is possible to generate unique response-data that has high confidentiality.

Description

technical field [0001] The present invention relates to a solid-state imaging device, a driving method of the solid-state imaging device, and electronic equipment. Background technique [0002] A Complementary Metal Oxide Semiconductor (CMOS) image sensor has been put into practical use as a solid-state imaging device (image sensor) using a photoelectric conversion element that detects light and generates charges. [0003] CMOS image sensors are widely used as a part of various electronic devices such as digital cameras, video cameras, surveillance cameras, medical endoscopes, personal computers (PCs), mobile phones and other portable terminal devices (mobile devices). [0004] In this way, the market scale of CMOS image sensors used for optical imaging in various fields is large, and its demand is expected to expand in the future due to the increase in mounting applications starting with automotive cameras. [0005] Furthermore, in recent years, IoT (Internet of Things, In...
