Mutual Authentication Based on Visual Cryptography and OCR for Secure IoT Service
Abstract— Recently, various devices providing many services to users have appeared in IoT (Internet of
Things). For these services, users as well as devices have to obtain authentication from server system, and
they need to authenticate server system, too. In this work, we suggest a mutual authentication between device
and server based on visual cryptography. Visual cryptography depends on human eyesight, and it is very
simple because no calculation is required for encryption or decryption of the information. We also adopt
OCR (Optical Character Recognition) to recognize the information for authentication. OCR plays the role of
humans and reads the overlapped images. For evaluation of our proposal, we simulated the authentication
mechanism using RaspberryPI II.
