Encrypted image recognition system, and the encrypted image recognition method

摘要

PROBLEM TO BE SOLVED: To provide a system for preventing information leakage by visual inspections from images displayed on various displays of portable terminals, personal computers, ATMs, etc., and various screens of cinemas etc. to a high degree, and sufficiently protecting privacy and security.;SOLUTION: An encryption image recognition system has: an encryption unit which generates and outputs a time division encryption image frame group, and an encryption key corresponding to the time division encryption image frame group according to an input original image; a transmission unit which generates a synchronization signal in response to the time division encryption image frame group and the encryption key which are input from the encryption unit, and outputs the synchronization signal with the time division encryption image frame group and the encryption key; a display unit which displays an encrypted image according to the time division encryption image frame group and the synchronization signal which are input from the transmission unit; and a restoration unit which restores the encrypted image in response to the encryption key and the synchronization signal.;COPYRIGHT: (C)2013,JPO&INPIT
