ABSTRACT:
An apparatus and method that stores image data on a disk along with an application program that operates on those images. The application program is limited to interacting with only the images on the disk. This interaction limitation is accomplished by creating a unique signature for each image from the data of the image and including that signature in the application. Prior to executing image processing operations on any retrieved image the application checks the signature of the image with the signature in the application and if there is not a match the application program is disabled.
