摘要:
In a device registration system, user authentication and device authentication of a CE device are executed in a single session, and the user and the CE device are associated with each other if these authentications succeed. The CE device obtains information for the user authentication from an IC card and a portable memory, and sends the information and device authentication information to a device registration unit. The device registration unit sends the information for the user authentication to a user authentication unit, and the device authentication information to a device authentication unit. The user authentication unit executes a user authentication process and sends information of the user to the device registration unit if the authentication succeeds. The device authentication unit executes a device authentication process and sends information of the device to the device registration unit if the authentication succeeds. The device registration unit associates the user information and the device information with each other.

To mount a TSOP on an interposer substrate, leads provided to the TSOP are joined to pads of the interposer substrate by a thermosetting conductive resin, and the TSOP exclusive of the leads is joined to ground layers formed in the interposer substrate by a thermosetting conductive resin. The interposer substrates with the TSOPs mounted thereon are stacked in eight layers in such a manner that the TSOPs face downward. Then, leads of the upper interposer substrate are joined to pads formed in the rear face of the lower interposer substrate by a thermosetting conductive resin, so that the interposer substrates adjacent in a vertical direction are connected.

A device authentication module and an encryption module can be connected via a dynamic link in a CE device. A random number is generated in an authentication server (5). The device authentication module (7) combines a pass-phrase and this random number to generate a digest, and transmits this and a device ID to the encryption module (8). The encryption module encrypts a communication pathway and transmits these items of information to the authentication server (5). The authentication server (5) searches for the pass-phrase based on the device ID and combines this and the generated random number to generate a digest. This digest is compared with the digest received from the encryption module (8) for device authentication. The encryption module (8) receives from the device authentication module (7) not the pass-phrase but a digest, and therefore can be connected via a dynamic link instead of a static link.

The present invention provides a device-authentication system capable of efficiently performing authentication before using a service through a network. A CE device (3) includes a browser (9) for accessing a service server (4) and an authentication module (7) for allowing an authentication server (5) to perform device authentication. A device-authentication plug-in (8) is a plug-in having a function of starting the authentication module (7). The device-authentication plug-in (8) can be specified by a predetermined MIME format, and the browser (9) starts the device-authentication plug-in (8) after receiving an EMBED tag having the MIME format.

This invention relates to a service providing system and a service providing method for allowing users to receive a service from a service server without having to submit their security-critical information to that server. A CE device 1 requests provision of the service by transmitting authentication information such as a device ID to a surrogate authentication server 2. The surrogate authentication server 2 authenticates the CE device 1 based on the authentication information and transmits a result of the authentication to the service server 3. In turn, the service server 3 provides the CE device 1 with the requested service based on the result of the authentication received from the surrogate authentication server 2. The CE device 1 then uses the service provided by the service server 3. This system can be applied advantageously to network-based marketing systems.
摘要:
A method and apparatus for reducing or enlarging an image. More specifically, this invention can increase or decrease the magnification ratio of an image even while scanning each line. This invention involves converting a first image with a first pel density to a second image with a second pel density. The intensity P of a new pel at a point p of the second image is represented by ##EQU1## where m is the number of reference pels of the first image that are sampled and that are within a given two-dimensional reference window when it is in a predetermined position corresponding to the point p, where Ii is the intensity of the i-th pel of the m sampled reference pels, and where .alpha.i is a contribution rate indicating how much the i-th pel contributes to the intensity P. Pre-calculated contribution rate data (.alpha.i) and pre-calculated shifting amount data indicating the relative amount the reference window is to be shifted are stored in a memory. The shifting amount data is used to position the reference window to a predetermined position where the m reference pels are sampled, and the contribution rate data and the values of the m sampled pels are used to determine the intensity P.

An information distribution system, a terminal device, an information distribution server, an information distribution server, an information distribution method, a terminal device connection method, an information processing program product, and a storage medium are provided. An information distribution system with a tree-structure network includes an information distribution server placed in a root node and terminal devices placed in nodes below the root node. Bidirectional communication can be always performed between the nodes. When a terminal device sends a request for information to be distributed from the information distribution server, each of the terminal devices constituting the information distribution system transfers the request to an adjacent node, the request transfer being performed from the requesting terminal device to a storage node storing the information, and transfers to an adjacent node the information supplied from the storage node, the information transfer being performed from the storage node to the requesting terminal device, in response to the transferred request. The requesting terminal device stores the transferred information.

In a semiconductor integrated circuit, a temperature sensor circuit includes a pulse source for generating a count pulse and a resistor having a resistance changing dependently upon a temperature change. The temperature detecting circuit is configured to convert the change of the resistance of the resistor responding to the temperature change, into the pulse number of the count pulses, in response to each application of a temperature measuring signal having a first frequency, in order to generate a count signal. A counter counts the count signal and accumulates a count value for each temperature measuring signal so as to hold the accumulated count value. The counter outputs the accumulated count value in response to a reset signal having a second frequency lower than the first frequency. The counter is then reset by the reset signal.
