Title: PUF-BASED CAMERA IMAGE STORAGE SYSTEM
Abstract:
A physical unclonable function (PUF)-based camera image storage system, comprising an image sensor, an A/D converter, a digital signal processor and a memory which are sequentially connected. The memory comprises a processing module, a PUF fingerprint module and a storage module; a light signal enters a camera, is optically processed by the image sensor, and then enters the A/D converter; an analog signal is converted into a digital signal, and image pixel information is stored into the memory after being processed by the digital signal processor; and the processing module receives the information that is processed by the digital signal processor, processes the same, and selects the pixel information bits to carry out logical operations and receives a value generated by the PUF fingerprint module for carrying out the logical operations. The system is entirely on the basis of the physical information of memory chips which may not be replicated, and the encrypted data may neither be replicated nor cracked. Therefore, the goal of high-reliability data encryption may be achieved, the embedded watermark information is more covert, and the timeliness and convenience of storage in a PC end may be achieved.
