Abstract: PROBLEM TO BE SOLVED: To provide a technique that can accelerate execution parallelized on multi processors or multiple cores, by well-balanced segmentation of a code of a model.SOLUTION: Blocks with internal states and blocks without any outputs among functional blocks included in a block diagram describing a model are focused on, and segments consisting of sets of blocks needed to calculate inputs to each block with an internal state and each block without any outputs are extracted by traversing a graph from the blocks with internal states and the blocks without any outputs in the opposite direction of the dependencies, where blocks can be duplicated among segments. Next, the segments are merged to reduce duplication, and the number of segments is reduced to a number for parallel execution. Here, the duplication between the segments is reduced by merging segments with many of the same blocks, and the number for parallel execution is typically the number of available cores or processors.

Abstract: PROBLEM TO BE SOLVED: To apply imbedding processing to image data or the like by adaptively optimizing imbedding data, denoting attached information such as copyright information depending on contents of the data which is an imbedding object. SOLUTION: An image division section 200 divides image data Vi into image blocks Iij and corresponds them to selection basic patterns Phij. Orthogonal conversion sections 24, 202 generate DFT coefficients I'ij, P'hij, and power component calculation section 208, 264 generate power components I"ij, P"ij. A basic pattern adjustment section 26 adjusts the coefficients P'hij to generate P'hij1-P'hijn. An imbedding pattern generating section 28 calculates a change before and after the P'hij1-P'hijn are imbedded to the I"ij, selects P'''hij1-P'''hij1 which give a change of a threshold εor bower from the P'hij1-P'hijn and selects one imbedding pattern P'ij which is detected most easily. A pattern imbedding section 204 adds the P'ij to the I'ij and imbeds the sum.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a system capable of safely detecting the additional information electronically embedded, at many and unspecified places. SOLUTION: A server reads the data where the additional information is embedded and then asks an anti-tamper device including a secret key to judge the embedding of the additional information. At the same time, the server reads a mask pattern out of the mask data, calculates the inner product of the mask pattern and the data including the embedded additional information and sends this inner product to the anti-tamper device. The anti-tamper device adds the inner product value sent from the server at the time of judging the embedding of the additional information and judges the threshold using the secret key. When the threshold is judged, a detecting mask pattern is produced from the secret key included in the anti-tamper device and the embedding of the additional information is judged based on the inner product value of the detecting mask pattern and the data received form the server.

Abstract: PROBLEM TO BE SOLVED: To obtain a low cost system which can safely perform data control through the use of electronic watermark technology by controlling data according to a control rule, having a token or control flag defined in advance. SOLUTION: In a step 800, it is checked from distributed data whether or not there is a control flag(CF) embedded by using electronic watermark technology. When no CF is detected, unrestricted control, e.g., duplication, video- recording, reproduction, etc., are performed. When a CF is detected, it is determined in a next step 820 whether or not there is an added token. When the result of the step 820 is NO, data control is inhibited. Namely, no duplication, video-recording, reproduction, etc., is done and the process is ended as it is. When the result of the step 820 is YES, the data control (duplication, video- recording, reproduction, etc.), by the control rule having a token or CF defined in advance is performed.

Abstract: PROBLEM TO BE SOLVED: To provide a new system capable of supplying authentication information in a form which is inseparable from an image data. SOLUTION: An image is halved and authentication information to hide in one image is obtained from the other image itself. Objective image data photographed by a digital camera is divided into an area D1 for generating a hush value and an area D2 for hiding a hush value H. A digest-calculating part calculates H from data of D1 and ciphers it by a secret key different for each digital camera, etc., to hide D2 , hiding can be executed by operating a pixel value in a real space or a frequency space to a degree of not being recognized visually. In D2 , additional information such as a time stamp, positional information of GPS can be hidden before hiding data from D1 .

Abstract: PURPOSE:To shorten preparation time and to simplify selection processing by evaluating whether or not there is any conflict in the adjacent relation of cells, assembling the respective cells based on the combination of cells having no conflict, and synthesizing a solid model. CONSTITUTION:Concerning the cell dividing model, in order to make a ridge line e1 existent, there are conditions that the ridge line e1 is made correspondent to a ridge line E1 of three drawings, the surfaces of any two cells among cells C1-C3 provided with the ridge line e1 cross (are not existent on the same plane) and only one cell is provided with the ridge line e1. Assuming that each cell is existent, a Boolean equation is applied as a normalizing formula so as to evaluate and calculate the combination (analysis) of assumption having no conflict. Based on the combination of cells having no conflict provided like this, the respective cells in the cell dividing model are selected and assembled, and several solid model candidates corresponding to a three-plane drawing are synthesized.

Abstract: PROBLEM TO BE SOLVED: To reduce accumulation of an error by calculating the error of prediction systematically in quickening a processing loop by speculative pipelining in a multi-core or multi-processor system.
SOLUTION: In an environment of a multi-core or a multi-processor system, the processing of each of the loops of a control block is suitably assigned to individual cores or processors as individual threads by a speculative pipelining method. A correction value is calculated by using the prediction variable value of the pertinent thread with respect to output based on the prediction input. The calculation of the correction value is applied as the gradient value as the approximate value of the primary differential coefficient of the prediction variable value. Generally, for a simulation system, there are several variable values, so that the primary differential coefficients are represented as a Jacobian matrix. Then, a matrix whose components are respectively the gradient value as the approximate value of the primary differential coefficient is called a Jacobian matrix. The calculation of the correction value is performed on the basis of the Jacobian matrix defined in this way.

Abstract: PROBLEM TO BE SOLVED: To read/write a value of a global variable speculatively and to enable rollback, in a simulation system by a computer. SOLUTION: For each global variable used in a logical process (LPn), writing of a value into a global variable is performed by writing write time and a write value thereof into a write table 1012, and reading of a value of a global variable is performed by reading of a value from the write table, and writing the time required therefor and a read value into a read table 1014. In response to writing performed into a global variable, in a simulation system, for an entry to a read table of each logical process, if an invalid entry is found in the read table by comparing entries in the write table, a doubt message is issued to a logical process related to the read table, and the logical process having received the doubt message performs necessary rollback processing.

Abstract: PROBLEM TO BE SOLVED: To efficiently simulate a system having a plurality of heterogeneous ECUs by software means. SOLUTION: Referring to an ECU emulator or each physical apparatus simulator as a logical process, each ECU emulator is speculatively emulated, and in each logical process, even if an input event is not reached, input is predicted to proceed with processing. By this speculative execution, processing is performed in advance without waiting for output of another logical process, thus improving parallelism in processes. If actual input received belatedly does not match with input for predicted speculative execution, the speculative execution ends in failure, thereby returning back to a state at the previous time, and on the basis of actual input, the processing is reexecuted. An allowable error is set for matching determination for actually received input and input at predictive speculative execution, thus enabling setting to satisfy both of accuracy and speed of simulation.

解决方案：参考ECU仿真器或每个物理设备模拟器作为逻辑过程，每个ECU仿真器被推测式仿真，并且在每个逻辑过程中，即使没有达到输入事件，预测输入继续进行处理。 通过这种推测执行，预先执行处理，而不等待另一逻辑进程的输出，从而改进进程中的并行性。 如果迟迟收到的实际输入与预测推测执行的输入不匹配，则推测执行结束失败，从而返回到先前的状态，并且根据实际输入，重新执行处理。 设置预测推测执行时实际接收的输入和输入的匹配确定的允许误差，从而使设置能够满足模拟的精度和速度。 版权所有（C）2010，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a digital watermark embedding/detecting method and system not demanding a signal for geometric correction. SOLUTION: A periodic pattern having repetition is used for an embedding pattern itself having information for embedding as digital watermarking, and a change in the period is observed at the time of detection, thereby calculating an enlargement and reduction rate. At the time of detection of digital watermarking, the enlargement and reduction rate of a screen image is acquired from digital data which is performed an enlargement and reduction, and next a detection processing of the digital watermarking is carried out based on the obtained enlargement and reduction rate.
