摘要:
An information processing method has a mechanism wherein mutual verification is performed between tasks and a computer operating system at the time of activating tasks, thereby judging the validity of tasks. The operating system evaluates a key which the task holds at the time of requesting service of the operating system, and permits execution of services only in the event that the operating system itself has the same key.A mail transmitting task specifies a mail ID and address to a mail body, management information is written by the operating system to a secure memory queue list based on the security level of the mail transmitting task and the security level of a transmitting function, and contents wherein mail transmission contents are enciphered with the mail ID, address value of management information, and address value of the mail body, as a key, are written to a buffer. The operating system deciphers the contents of the buffer wherein the received contents exist, with the mail ID, address value of management information, and address value of the mail body, as a key, based on the security level of the mail receiving task and the security level of a receiving function, and copies this onto a buffer on the mail receiving task.

An information processing apparatus includes: an record information obtaining mechanism which obtains record information representing a provision destination of one predetermined electronic information property by a terminal device relating to a provider of the electronic information property; a weighting mechanism which extracts the provision destination included in the obtained actual achievement information and performs weighting on the extracted provision destination based on a reference predetermined in accordance with the attribute of the provision destination; and an evaluation value calculating mechanism which calculates an evaluation value of the provider based on the weighted value.
摘要:
An information processing apparatus includes a notification reception unit that receives information from a first terminal device when the first communication is performed between the first terminal device related to a provider of a product or a service and a second terminal device related to an evaluator, a sorting specification unit that specifies at least one of reliability sorting, security sorting of the first terminal device, and security sorting of the second terminal device, a link authentication unit that specifies a link authentication method of confirming a state of a second communication performed between the first terminal device and the second terminal device based on the specified result, and performs a process related to the link authentication using the specified method, and an evaluation information reception unit that receives evaluation information from the first terminal device.
摘要:
A communication device has a first communication section that supports a first communication mode having a low communication rate and a second communication section that supports a second communication mode having a higher communication rate than the first communication mode. The communication device includes a packet generation section and a communication control section. The packet generation section generates a first portion containing authentication information used for connection authentication for the second communication mode and a second portion other than the first portion. The communication control section performs control to cause the first communication section to transmit the first portion and to cause the second communication section to transmit the second portion after the connection authentication succeeds using the authentication information contained in the first portion.

摘要:
An audio decoding apparatus for decoding and reproducing a plurality of compressed audio streams simultaneously without sound interruption, even when the number of samples per frame is different. The audio decoding apparatus includes: a first and second audio decoder which decode two inputted compressed audio streams, and output audio data; a first and second intermediate buffer which temporarily hold the outputted audio data; a first and second audio output unit which convert the audio data into audio signals and output such audio signals; an output control unit which reads the audio data from the first and second intermediate buffer, and transmits the audio data to the first and second audio output unit. The output control unit repeats the reading and transmission of either the same number of samples of audio data or the number of samples of audio data for the same amount of transmission time.
