Abstract: A method for generating a public identity for authenticating an individual carrying an identification object, the method including: entering an initial biometric datum of the individual; generating a first key from the biometric datum; generating a second key derived from a datum generated by a security component of the object; generating an initial encryption key combining the first key and the second key; communicating with a server a first identity of the individual in connection with the initial encryption key; generating by the server a public identity by encrypting the first identity using the initial encryption key, the public identity being stored by the server in connection with the initial encryption key. The public identity is not significant, but is secured by a strong connection between the object and biometry of the individual.

Abstract: It is an object to generate a desired composite image in which a motion area of a subject is correctly composited. A difference image between a base target and an aligned swap target is generated (S1021), and an extracted contour in the difference image is determined according to the active contour model (S1022). The inner area of the contour and the outer area of the contour are painted with different colors to be color-coded so as to generate a mask image for alpha blending (S1023). Using the mask image thus generated, the swap target that is aligned with respect to the base target is composited with the base target of the base image by alpha blending (S1024).
