摘要 A method for image encryption using a 1-D joint transform correlator is described. By use of line functions, a 2-D object is encrypted first in one direction, then in the perpendicular direction. The principle of the method and experimental results are given. １ＩｎｔｒｏｄｕｃｔｉｏｎＢｅｃａｕｓｅｏｆｕｓｉｎｇｏｆｖａｒｉｏｕｓｃａｒｄｓｉｎｏｕｒｌｉｖｅｓ，ｅ．ｇ．，ＩＤｃａｒｄｓ，ｃｒｅｄｉｔｃａｒｄｓ，ｍｅｄｉｃａｌｃａｒｄｓ，ｄｒｉｖｅｒｌｉｃｅｎｓｅｓ，ｅｔｃ．，ｐｒｅｖｅｎｔｉｎｇｃａｒｄｆ...
