Abstract: It is one object of the present invention to provide a method and system for embedding an electronic watermark directly in an MPEG stream. ÄConstitutionÜ An intra-macroblock of an I-frame or of a P or B-frame is detected in an MPEG stream, and following the detection of an intra-macroblock of the I-frame or of the P or B-frame, data for one macroblock are extracted from the MPEG stream and buffered. An embedding pattern is embedded in the buffered macroblock without changing the length of VLC, and the resultant macroblock is returned to the MPEG stream. More specifically, a DC factor is extracted from the buffered macroblock, and a pseudorandom number is generated to produce an embedding pattern. Then, whether the bit length of the DC factor will not be changed by embedding the obtained embedded pattern is determined. When the bit length of the DC factor not be changed, the embedding pattern is embedded in the buffered macroblock. When the bit length will be changed, whether 1/2 of the embedding pattern can be embedded is determined. If possible, 1/2 of the embedded pattern is embedded in the macroblock.

Abstract: Data hidden in a plurality of contents is protected from illegal access by a third party. An embedding process is performed by using a frame pattern (mark) that is composed of multiple embedded block patterns comprising several different types and wherein the embedding process is varied in accordance with the time and the frame. One embedding method mixes at random several types of frame patterns having different arrangements of block patterns. The embedding method may change at random a range in which a block pattern is embedded. An embedded mark is detected by processing in parallel a plurality of patterns that are to be detected in contents, and if as a result of detection there is a reaction, it is ascertained that a mark is present. An illegal process may be traced by using an electronic fingerprint obtained by entering a false detection mark in a detector or by using an electronic fingerprint using a random sync signal for an embedding detector.

Abstract: To provide a data hiding method of hiding media data in message data and a data extraction method of extracting the hidden data wherein message data is dispersively hidden in media data such as an image or sound to prevent a third person from modifying the message data easily. A data hiding method in which media data is expressed as a media array while message data is expressed as a message array so that the array elements of the message array can be dispersively hidden in the message array based on a state values specifying a particular array element of the media array, comprises the steps of: (a) determining the j-th (j ≥ 0) state value Sj; (b) determining (j + 1)-th state value Sj+1 based on the j-th state value, the array element of the media array indicated by the j-th state value, and the array element of the message array; and (c) hiding data with respect to the array element of the media array indicated by the (j + 1)-th state value Sj+1.

Abstract: Copying of watermarked DVD data or broadcast digital image data is controlled by appending a token to the data. When a copy is made the token is deleted from the data to prevent further copying. The token may also be used to control playback and reception of data. The token is generated from the DVD data using a hash code or CRC code. The technique may be applied in a set-top box, personal computer, facsimile machine or mobile telephone.

Abstract: PROBLEM TO BE SOLVED: To prevent the accumulation of the errors of values to be simulated in a simulation system.
SOLUTION: The simulation system is provided with a prediction module 710 for predicting a plurality of future values from the values of a plurality of input events in a logical process. The prediction module predicts the values of a plurality of future events from the values of a plurality of past events, and performs precedence speculation based on the predicted values of events until a new event is input. An error is generated between the plurality of newly predicted values of the events and the plurality of previously predicted values of events. The cumulative sum of the errors between the plurality of this time newly predicted values of events and the plurality of previously predicted values of events is calculated, and the number m of events whose cumulative sum falls into a prescribed threshold is calculated. The prediction module 10 rolls back the precedence speculation to time n+m within the range of the allowable error. The cumulative errors are distributed to a certain future point of time n+2m so as to be adjusted. Thus, it is possible to prevent errors from being accumulated.

Abstract: PURPOSE: To easily structure a shape model on which the intension of a designer is faithfully reflected without restrictions on operation such as input order when the shape model is generated and corrected. CONSTITUTION: Geometric elements (plane, side, vertex, etc.) and geometric restrictions among them (size, angle, etc.) are inputted, a dependency relational expression generating mechanism 7 of a geometric inference part 3 generates a by directional dependency relational expression for those geometric elements, and a dependency order calculating mechanism 8 automatically calculates a dependency state (dependency order data). Then a geometric attribute calculating mechanism 9 determines the attribute values of the geometric elements and a modeler 4 generates and outputs the shape model to a display device 6. At the time of correction, a contradiction detecting and eliminating mechanism 10 calculates geometric elements to be altered by using the memory dependency order data to determine their attribute values. Further, excessive geometric restrictions and contradiction are detected and an eliminating means is displayed on the display device 6.
