| 20090174912 | METHOD OF EMBEDDING DATA IN ORIGINAL IMAGE WITH REDUCED EFFECT ON VISIBILITY OF ORIGINAL IMAGE - A PC generating image data divides data to be embedded into a predetermined size and arranges it in a predetermined area of a watermarking image. In the predetermined area are defined positions a-h assumed by an information dot configuring an information pattern based on the data to be embedded, and, of positions a-h, a position defined for the information pattern is assumed by a point dot. Of positions a-h, a position that is not defined for the information pattern is assumed by a linear dot. Furthermore in the predetermined area there is a position assumed by a positioning dot defining the predetermined area, and this position is assumed by a point dot. The linear dot has a geometry extending in one of the main scanning direction and vertical scanning direction of an image formation apparatus that allows higher performance in reproducibility for a line. | 07-09-2009 |
| 20090190796 | METHOD OF DETECTING EMBEDDED DATA FROM IMAGE DATA HAVING A PLURALITY OF TYPES OF DATA EMBEDDED THEREIN - Data to be embedded is divided and thus embedded in areas internal to a block corresponding to a predetermined region of a scanned image. Of the areas, a defined area has the embedded data's identification information embedded therein. A detection apparatus includes a counter including a region including a region storing identification information and a region storing a count value corresponding to embedded data divided that is detected in an area other than the defined area, and classifies a count value corresponding to embedded data divided that is detected from a scanned image for each identification information detected in the block, and stores it to the counter. The detection apparatus identifies data stored for each identification information that has the largest count value for each area as data embedded in that area, and reconstructs the embedded data. | 07-30-2009 |
| 20090310873 | IMAGE PROCESSING APPARATUS CAPABLE OF EFFICIENTLY COMPRESSING AN ORIGINAL IMAGE - An image processing apparatus successively counts numbers of continuous blocks starting from a left end in view of a number of color(s) forming each block and the color of a preceding block. In this counting, when a first block formed of two colors is input, then second block formed of one of the two colors of the first block is input and then blocks formed of the same one color as the second block are continuously input (second to fourth), the image processing apparatus handles the second to fourth blocks as one-color blocks continuing after the two-color block, and encodes the first to fourth blocks into a code indicating identification information to the effect, a continuation number of the two-color block, color information of each color, information specifying the color of the one-color block being one of the two colors, and the continuation number of the one-color blocks. | 12-17-2009 |
| 20100060945 | INFORMATION EMBEDDING METHOD, ITS PROGRAM AND INFORMATION EMBEDDING DEVICE - There are used a first information embedding method that is used for embedding first information and specified by a first information expression rule and a second information embedding method that is used for embedding second information and specified by a second information expression rule different from the first information expression rule. The first information and the second information are so embedded that at least parts of the first and second information overlap with each other in an identical area. This makes it possible to provide an information embedding method, its program, and an information embedding device capable of generating an embedded image that is beautiful in appearance because the boundary between the first and second information is inconspicuous and is also safe because it is difficult to decipher the embedded information. | 03-11-2010 |
| 20100128322 | IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD AND PROGRAM THEREOF - It is possible to provide an image processing device, an image processing method, and its program which generate a positioning pattern of an information pattern in accordance with block information. This eliminates the problem that a block number cannot be identified although an information block position can be identified, i.e., the problem that information for identifying an information block cannot be sufficiently extracted. If an information pattern is identified, the extracted information can be used effectively. Moreover, it is possible to enhance the information embedding efficiency. | 05-27-2010 |
| 20100202692 | INFORMATION EMBEDDING APPARATUS AND INFORMATION EMBEDDING METHOD FOR ADDING INFORMATION TO DOCUMENT IMAGE BY EMBEDDING INFORMATION THEREIN, INFORMATION DETECTING APPARATUS AND INFORMATION DETECTING METHOD - In an information embedding apparatus, an image compositing portion selectively reads an embedding pattern from a plurality of types of the embedding patterns in accordance with an embedding information for a background of a document image. The image compositing portion further composites the read embedding pattern into the background of the document image in a document image data generated based on a document data and outputs the composite document image data. The embedding pattern includes a data dot placed at a position in accordance with the embedding information, a position dot placed at a position for instructing a reference position used for identifying the position of the data dot, and an assisting dot placed at a position for assisting the instruction of the reference position by the position dot. | 08-12-2010 |
| 20100306842 | Information Processing Apparatus Capable of Authentication Processing Achieving Both of User Convenience and Security, Method of Controlling Information Processing Apparatus, and Recording Medium Recording Program for Controlling Information Processing Apparatus - Whether a log-in button has been pressed or not is determined. When it is determined that the log-in button has been pressed, an ID selection screen is displayed. Whether an ID has been selected or not is determined. When it is determined that an ID has been selected, whether a secure printing job is present or not is determined. Thereafter, whether password matching is successfully achieved or not is determined. Thereafter, whether a password image function is ON or not is determined. Then, when it is determined that password matching was successfully achieved and a password image authentication function is ON, password image authentication is carried out. | 12-02-2010 |
| 20100319057 | Information Processing Apparatus Capable of Authentication Processing with Improved User Convenience, Control Program for Information Processing Apparatus, and Recording Medium Having Control Program for Information Processing Apparatus Recorded Thereon - Whether box access is made or not is determined. When it is determined that a box region is accessed, a box ID entry screen appears. CPU determines whether a box ID is entered or not. If it is determined that a box ID is entered, then device information is obtained. After the device information is obtained, whether a hardware keyboard is present or not is determined. If it is determined that a hardware keyboard is present, a password authentication screen appears. If it is determined that no hardware keyboard is present, an image authentication screen appears. | 12-16-2010 |
| 20110023112 | Authentication Method, Authentication Device and Computer-Readable Medium Storing Instructions for Authentication Processing Capable of Ensuring Security and Usability - An authentication method in a system having a display and a storage device is provided. The authentication method includes the steps of registering an object selected for each user from among a plurality of visually distinguishable objects prepared in advance as a key object in the storage device; and presenting the plurality of objects to the display, accepting selection of an object by a user to be authenticated, and performing authentication based on matching/mismatching of the selected object with the key object registered in association with the user. The step of registering includes a step of determining a degree of freedom of selection of the object at the time of registration of the key object according to a degree of overlapping of the key object already registered in the storage device. | 01-27-2011 |
