Abstract:
1. An image processing apparatus, comprising: a verification data extractor configured to receive a set of protected images in a sequential order, and to extract a set of detected verification data from the set of protected images; a verification data generator configured to generate a set of generated verification data, with each generated verification data generated based on the contents of a corresponding protected image and the contents of a protected image preceding or succeeding the corresponding protected image; a verification data comparator configured to compare the set of generated verification data with the set of detected verification data to generate a comparison result, and to determine whether the set of protected images differs from a set of original images based on the comparison result, wherein the verification data comparator is further configured to continue determining whether subsequent images in the set of protected images differ from corresponding images in the set of original images after determining that an image in the set of protected images differs from a corresponding image in the set of original images.
