An information processing terminal is provided with a data acquiring means for reading data from an external recording medium; a program storing means for storing a plurality of application programs; a program executing means for executing the stored application programs; and a program selecting means for selecting the application program to be executed by the program executing means. The program selecting means selects the application program to be executed from the programs stored in the program storing means, corresponding to the data acquired through the data acquiring means, and processes the data acquired through the data acquiring means by the application program selected by the program selecting means.

There is provided a mobile body track identification system that determines which mobile body matches which detected track with a high precision irrespective of frequent interruption of tracks of a mobile body detected in a tracking area. Herein, hypotheses are generated by use of sets of track-coupling candidate/identification pairs, which combines track-coupling candidates, combining tracks of a mobile body detected in a predetermined time in the past, and identifications of the mobile body and which satisfies a predetermined condition. Next, identification likelihoods are calculated as likelihoods of detecting identifications in connection with tracks indicated by track-coupling candidates included in track-coupling candidate/identification pairs ascribed to each of the selected hypotheses. Identification likelihoods are integrated per each track-coupling candidate/identification pair, thus calculating an identification likelihood regarding the selected hypothesis. A most-probable hypothesis is estimated based on identification likelihoods of hypotheses.

To provide an architecture information processing system having a small circuit size capable of reducing power consumption and cost, on which system a circuit simultaneously executing encryption processing and message authentication (falsification detection processing) can be mounted. An information processing system includes at least: a parameter storage section that retains an initialization vector used as a starting block of concatenation and an encryption key used for encryption; a one-way hash calculation section that executes a one-way hash calculation as a technique for realizing message authentication and functioning in place of the conventional common key block encryption (DES encryption) operation as an encryption operation section of a block encryption mode use section performing encryption processing and/or decryption processing as a CFB mode and/or an OFB mode; and a key overlay operation section that performs calculation for overlaying an encryption key retained in the parameter storage unit on data input to the encryption operation section.

A website access system allowing easy operation and a small number of steps for accessing a desired one of a great number of websites is disclosed. A plurality of domain areas are provided, which is determined so that a number of information providers is restricted. An address registration database retrievably registers a plurality of address identifiers uniquely identifying respective ones of website addresses which have been registered for each of the domain areas. An access management server receives an address identifier from the user terminal located in one of the domain areas, searches the address registration database for a corresponding website address according to the address identifier and the domain area where the user terminal is located, and then uses the corresponding website address to make the user terminal access the desired website on the network.
