Image processing apparatus and image forming apparatus

TL;DR: In this article, an image processing apparatus, comprising of an input portion that inputs image data of a plurality of pages of a document, a password detector that detects a password given to each of the pages, and a password judger that judges from a detecting result drew by the password detector about each page, whether or not a shared password issued for each page in common is detected.

TL;DR: In this paper, a content distribution method for video copyright authentication and security comprising the steps of invisibly watermarking digital video data input from a video data source to create watermarked data, encrypting the watermarked digital data using an encryption key to create encrypted video data, sending the encrypted digital data and a decryption key to a distribution network, decrypting the encrypted watermark digital data to generate video data and adding visible watermarked data to the video data to create visibly encrypted water-marked data compressing the encrypted data at the receiver to generate decompressed data;

TL;DR: An image formation apparatus includes a visible image data generation section that acquires content data of a print object and generates image data of the visible image containing the content, an invisible image data generating section that generates image images of a code image describing predetermined code information, the code image being an unseen image that can be hardly recognized by the human being as mentioned in this paper.

TL;DR: In this article, the authors propose a method that includes: receiving, at a mobile device, data encoding a first digital watermark present on the identification document; extracting a first portion of personally identifiable information encoded by a spatial luminance pattern associated with the first digital signature; and validating the identification documents based on at least one of the first portion or the second portion of personal information.

TL;DR: In this paper, an image forming device is equipped with a head 211 consisting of plural recording elements for forming an image on a recording medium based on given image data, and a density-unevenness characteristic data-creation part 202 which creates density-uniformity characteristic data based on density unevenness data on a pattern formed by using the head 211 and attribute informations used in forming the pattern.

TL;DR: In this paper, a document distributing method is proposed using access control information separated into invisible data embedded as an electronic watermark and visible data described in a structured document to achieve prevention of unauthorized alteration of document data, authentication thereof, and prevention of authorized access thereto.

TL;DR: In this paper, a printed image can be redundantly encoded by printing a visible image using a colorant with a luminance that contrasts with that of the output sheet and printing a redundant image with a colourant that varies only slightly from that of an output sheet.

TL;DR: A mark management server for certifying digital data based on a digital mark to enable realization of identity authentication and data certification when the digital data is transmitted or received on a network is described in this paper.
