Patent ID: 7379214

Claim:
An image processing apparatus comprising: feature value generating means for generating feature values of given pages of a document including N pages, N being an integer not less than 2; embedding means for embedding the generated feature values of the given pages in other pages corresponding to respective given pages; and output means for outputting the document in which the feature values of the given pages have been embedded in the corresponding other pages by the embedding means, wherein the embedding means embeds a feature value of a k-th page in a j-th page, k being a natural number satisfying 1≦k≦N and j being a natural number satisfying 1≦j≦N and j≠k, wherein j is k+1 when 1≦k≦N−1, wherein j is 1 when k is N, wherein the feature value generating means generates feature values of k-th page (k=N) before the feature value generating means generates feature values of k-th page (1≦k≦N−1), and wherein the embedding means embeds a feature value of a k-th page (k=N) in a j-th page before the generating means generates a feature value of the j-th page.
