    다국어 초록 (Multilingual Abstract) kakao i 다국어 번역

    A new image encoding and identification scheme is proposed for security verification by using a CGH (computer generated hologram), random phase mask, and correlation technique. The encrypted image. which is attached to the security product, is made by multiplying QP-CGH(quadratic phase CGH) with a random phase function. The random phase function plays a key role when the encrypted image is decrypted. The encrypted image can be optically recovered by a 2-f imaging system and automatically verified for personal identification by a 4-f correlation system. Simulation results show the proposed method can be used for both the reconstruction of an original image and the recognition of an encrypted image.
