Abstract
An imaging device includes an image sensing device, a private key generation unit, and an image encryption unit. The image sensing device includes an image generator configured to generate image data acquired by capturing as image, and a physical unclonable function (PUF) generator configured to generate physical unclonable function (PUF) data including information about at least one fixed pattern noise (FPN) data value and at least one random telegraph noise (RTN) data value. The private key (KEY) generation unit generates a private key based on the at least one FPN data value and the at least one RTN data value that are acquired from the PUF data. The image encryption unit encrypts the image data using the private key. A first transistor included in the PUF generator exhibits different properties from a second transistor that is included in the image generator and corresponds to the first transistor.
