1. An information processing apparatus for registration of information related to a latent image and information related to a background at an image processing apparatus that outputs an image of a ground tint including a latent image and a background, comprising: a storage unit storing one or more image patterns of a background and one or more image patterns of a latent image; a pattern selection unit selecting an image pattern of a background and an image pattern of a latent image from among the image patterns stored in said storage unit; a ground tint generation unit generating image data of a ground tint using the image pattern of a background and the image pattern of a latent image selected by said pattern selection unit from the image patterns stored in said storage unit; a determination unit determining whether there is a predetermined empty region at a border area between the image pattern of a background and the image pattern of a latent image in the image data of a ground tint generated by said ground tint generation unit; and a registration unit registering the image pattern of a background in association with the image pattern of a latent image when said determination unit determines that there is no predetermined empty region at the border area between the image pattern of a background and the image pattern of a latent image.
