摘要:
Area data indicating an encryption area of image data and level data indicating an authority level for the encryption area are received. Upon being triggered by an input password, an encryption key is generated for each received authority level. Check data to be detected in verifying whether or not the encrypted image data in the encryption area is appropriately decrypted through decryption is implanted in the encryption area. Image encryption is performed on the encryption area where the check data is implanted, by using the encryption key corresponding to the authority level designated for the encryption area. In decryption, all decryption keys corresponding to all authority levels lower than or equal to the set authority level are used to decrypt each encryption area and determines whether or not an appropriate decryption has been performed on the basis of the result of the detection of the check data.

The invention provides a carburization treatment method in which the carburization treatment is conducted under a condition where an atmosphere within the furnace is maintained at a high carbon potential which is slightly blow a carbon solid solubility. Preferably, the internal pressure within the furnace is kept at 0.1 to 101 kPa, the hydrocarbon gas is one, two or more than two kinds of gases selected from the group consisting of C3H8, C3H6, C4H10, C2H2, C2H4, C2H6 and CH4, while the oxidative gas is an air, an O2 gas, or CO2 gas.
摘要:
A disk brake is provided which is free from problems attributed to the obverse-reverse orientation of a cover member as installed. A cylinder portion (21) slidably accommodating a piston is formed from a plate-shaped cover member (43) constituting the bottom thereof and a caliper body main part (46) having an opening (45) that is closed with the cover member (43). The cover member (43) is joined to the caliper body main part (46) to close the opening (45). A projection (60) is provided on one side of the cover member (43) that faces inside the cylinder portion (21), and a blind hole (61) is provided on the other side of the cover member (43). When the cover member (43) has been installed in the normal orientation, the blind hole (61) remains after the outer surface of the bottom of the caliper body has been subjected to face cutting after the installation of the cover member (43).

摘要:
A figure pattern expressing information to be embedded, or a position of an area in which the information to be embedded exists, is embedded in an area other than the background of image data, thereby generating image data embedded with a watermark. Then, the figure pattern is detected from the generated image data embedded with the watermark, and embedded information expressed by the detected figure pattern or embedded information existing in an area at a position expressed by the detected figure pattern is detected.

摘要:
A recording/reproduction device 10 receives content broadcast from a content provision device 11. The recording/reproduction device 10 encrypts the received content using a device key, to generate first encrypted content. The recording/reproduction device 10 decrypts the first encrypted content to obtain the content, performs an image conversion on the obtained content to generate converted content, and encrypts the converted content using a medium key to generate second encrypted content. The recording/reproduction device 10 writes the second encrypted content, the medium key, and the device key to a portable medium 14. When the portable medium 14 is inserted in a mobile information terminal 15, the mobile information terminal 15 decrypts the second encrypted content using the medium key to obtain the converted content, and reproduces the converted content.
摘要:
A frame group target bits number calculating unit (31) reads the total number of bits on frame group basis allocatable to residual frames from a storing unit (36), updates subtracting the number of generated bits used to code a preceding frame, and transmits to a next frame target bits number calculating unit (32). The next frame target bits number calculating unit (32) calculates the target number of bits to be allocated to a next frame based on the received total number of bits and the number of residual frames with considering a frame rate value, Rf. An average frame bits number calculating unit (33) calculates the average number of bits allocated to preceding frames. A calculating unit (34) multiplies the calculated average number of bits by a predetermined coefficient, compares the resulting value with above target number of bits, selects the greater number and transmits it to a quantization step calculating unit (35).
摘要:
A control system for a plant is provided. This control system can control the plant more stably, when the model parameters of the controlled object model which are obtained by modeling the plant, which is a controlled object, are identified and the sliding mode control is performed using the identified model parameters. The model parameter identifier (22) calculates a model parameter vector (θ) by adding an updating vector (dθ) to a reference vector (θbase) of the model parameter. The updating vector (dθ) is corrected by multiplying a past value of at least one element of the updating vector by a predetermined value which is greater than “0” and less than “1”. The model parameter vector (θ) is calculated by adding the corrected updating vector (dθ) to the reference vector (θbase).
