Abstract: PURPOSE: A method for generating and restoring a color code by using BC(Binary Convolution)-CGH(Computer Generated Hologram) is provided to increase the reliability of data recovery and an error recovery ratio by detecting and recovering an error randomly generated in the color code. CONSTITUTION: A data generating unit generates encoded data by logically calculating input data and a random mask(S12). A logical relation between neighboring bytes is generated by performing first binary convolution to the encoded data(S13). A color code is generated by performing Fourier transformation to the convoluted data(S15). The random mask includes phase information for encoding the input data. The logical relation is generated by calculating an input byte of the data and input bytes for the convolution.

Abstract: PURPOSE: An apparatus for authenticating a user by using a security tag storing biometric information and a method thereof are provided to implement the security tag to which a lenticular film is attached, thereby preventing the illegal forgery and alteration of the security tag. CONSTITUTION: A security tag (110) stores the encrypted biometric information of a user. A photographing unit (211) provides a first image and a second image. The first image is generated by photographing the security tag in a first position according to the authentication request of the user. The second image is generated by photographing the security tag in a second position symmetrical to the first position. A data recovery unit (212) recovers the encrypted biometric information from the images. A personal information input unit (220) scans and reads the real biometric information of the user. A biometric information matching unit (230) determines whether the recovered biometric information is coincident with the real biometric information, and accepts or rejects the authentication request of the user.
