Abstract: The present invention relates to a method and apparatus for authenticating various types of digital certificates by using a text embedding method. The execution of the present invention is divided into two cases, one case including images in the certificate and another case not including the images in the certificate, according to the characteristic of the certificate. In the former case, a text embedding method is applied to images included in the certificate to embed a series of information text (a specific number of the certificate, and issuing organization, name of a person in charge, etc.) designated by a person who issues the certificate into the images. In the latter case, there is generated an image imperceptible to the human eye but having the same color as the ground color of certificate.

Abstract: A watermarking procedure wherein each of a set of copies of the work has a slightly-modified form of a "baseline" watermark that is placed within a critical region of the data. The slight variations in the watermarks, however, are not perceptually visible and do not interfere with the work. If multiple persons collude to attempt to create an "illicit" copy of the work (i.e., a copy without a watermark), however, at least one of the modified watermarks is present in the copy, thereby identifying both the illicit copy and the copier.

Abstract: Multiple transform utilization and applications for secure digital watermarking. In one embodiment of the present invention, digital blocks in digital information to be protected are transformed into the frequency domain using a fast Fourier transform. A plurality of frequencies and associated amplitudes are identified for each of the transformed digital blocks and a subset of the identified amplitudes is selected for each of the digital blocks using a primary mask from a key. Message information is selected from a message using a transformation table generated with a convolution mask. The chosen message information is encoded into each of the transformed digital blocks by altering the selected amplitudes based on the selected message information.

Abstract: The present invention relates to a method for certifying and subsequently authenticating original physical or digital documents. The concept of the evidence lies in the dual nature of a physical information item and a digital information item, one being the reference for the other that cannot lie amended at the risk of the evidence being lost. For a physical original document associated with a bubble seal there is a corresponding time-and-date-stamped, proprietary paperless reference counterpart. For a time-and-date-stamped, proprietary digital original document there is a corresponding reference counterpart in the form of a bubble seal.

Abstract: A computer is provided with an application and a printer driver. A user of the computer generates image data using the application. When the image data is for a plurality of pages, the user selects a desired watermark for each of the plurality of pages. The printer driver converts the image data into print data, and combines selected watermarks with the print data for corresponding pages, thereby generating updated print data. The updated print data is output as a single print job to the printer. The printer executes printing operations based on the print job so as to print an image on a plurality of pages, each formed with a corresponding watermark.

Abstract: In a data transmission apparatus and method of the present invention, a specific operator ID for an operator who uses a data processing device to process image data to be copied or transmitted, is selected. Specific owner IDs for owners who are authorized to access the image data, are selected. User identification data, inclusive of all operator IDs and owner IDs correlated to the data processing device, are stored in a storage device each time image data is captured by the data processing device. Allocation of the stored user identification data to each of the image data is managed by reading items of the user identification data from the storage device in response to the selections of the specific operator ID and the specific owner IDs and displaying the user identification data items.
