Solid-state imaging device, method for driving solid-state imaging device, and electronic apparatus for preventing tampering of an image

A method for driving a solid-state imaging device including a pixel portion in which a plurality of pixels each including a photodiode are arranged in a matrix and a reading part for reading pixel signals from the pixel portion, comprising

• an information acquisition step of acquiring at least one information of fluctuation information of the pixels and fluctuation information of the reading part
• a key generation step of generating a unique key by using the fluctuation information acquired in the information acquisition step as key generation-use data and,
• a discrimination data generation step of combining the unique key generated in the key generation step and an acquisition data acquired from the solid-state imaging device,
• in the key generation step, processing the key generation-use data for enhancing the tamper resistance for making the unique key difficult to break as tamper resistance enhancement processing, wherein the tamper resistance enhancement processing in the key generation step
• performs averaging processing between two pixels which are adjacent in the reading direction of the key generation-use data and
• judges magnitude between the two adjacent pixels to binarize the data in the data subjected to the averaging processing.
