The present invention intends to hold safely string information such as secret information, or the like, and also to lessen user's burden of storing the information in connection to the string information. In registering the secret information, a coding section 16 synthesizes input correct secret information SD and individual characteristic information under a predetermined rule, and produces a code word S16. A check symbol for error correction is produced in the course of the coding of the coding section 16, and this check symbol is stored in a storing section 20. In reproducing the secret information, an error correcting section 22 applies an error correcting process using the check symbol stored in the storing section 20 to a code word, which is produced by the coding section 16 based on the input secret information SD and the individual characteristic information, as the object. Accordingly, the correct secret information is reproduced.

The present invention has an object to provide a communication terminal, a secure device, and an integrated circuit, by which before data is transmitted by a transmission-sided communication terminal, a security process operation is carried out under environment of a communication terminal having a possibility of using the data with respect to threats caused by computer viruses and the like, which are operated in an illegal manner and are operable in correspondence with various sorts of platforms, and thus, safety characteristics with respect to the data can be assured.When a portable telephone 101 transmits data, a data analyzing unit 113 extracts identification information of a communication counter terminal 103 described in transmission data, and selects a predetermined verifying operation in response to an environment of the communication counter terminal 103 by referring to a permission information database 114. The selected security process operation is carried out by a data verifying unit 116, and the transmission data is notified to the communication counter terminal 103 in combination with security process information.

When a special relationship is present between IC card owners, authority of one of the IC card owners cannot be easily given to the other owner of the IC card. However, an IC card of a second owner can issue a public key certificate of the IC card of a first owner so that the IC card of the first owner can be recognized as a child card of the IC card of the second owner. Thus, the first generation card authenticated by a route authentication station is set as an ancestor which can generate a descendent card which receives the authentication. By checking which parent card has issued the public key authentication owned by the child card, it is possible to given the authority of the parent card to the child card.

With respect to a secure device 10 for executing a data storing operation and a data calculating operation under secrecy condition, a first application program 15 and a second application program 11 are retained. The program 15 causes an information processing terminal 30 mounted thereon this secure device 10 to execute a process operation by utilizing a resource of this information processing terminal 30. The program 11 causes the secure device 10 to execute such a process operation under secrecy condition in conjunction with the process operation of this information processing terminal 30. When this secure device 10 is mounted on the information processing terminal 30, this secure device 10 loads the program 15 to the information processing terminal 30 so as to install this loaded first application program therein. Then, a terminal application program required to execute a service is automatically installed to the information processing terminal 30.

An image processing device for displaying a planar map which can be easily viewed by a user without increasing the amount of processing. A planar map generating device (103) is provided with: an image acquisition section (301) for acquiring images wherein objects are imaged and the three-dimensional coordinates of the objects can be calculated; a coordinate acquisition section (302) for extracting the upper surface of a first object existing on a reference surface from the images to acquire the coordinates of the feature point of the extracted upper surface; and a first planar map generating section (303) for generating a first planar map by adjusting the size and position of the upper surface so that the values of the coordinates equivalent to the direction perpendicular to the reference surface become the same as those of the reference surface by using the acquired coordinates.

An information storage apparatus capable of setting the number and sizes of partitioned areas resulting from partitioning a memory area based on a user's intention is provided. For this purpose, an information storage apparatus having a plurality of partitioned areas of different security levels in a memory area is provided with an area control section that controls addresses of partitioned areas in the memory area, an area update condition control section that controls update conditions when the number or sizes of partitioned areas are updated, an area update decision section that decides whether a partition request requesting updating of the number or sizes of partitioned areas satisfies the update conditions and an area update section that executes, when the partition request satisfies the update conditions, updating of the partitioned areas in the memory area according to the partition request. The partitioned areas in the memory area of this information storage apparatus are updated at a partition request reflecting the user's intention in accordance with the user's intention.

In a document retrieving apparatus, an audio input section converts a sound into a character pattern. A language model storing section stores likelihood information. A word choosing section obtains a word selection result based on the likelihood information. A retrieval condition producing section produces retrieval conditions based on the word selection result. A document storing section stores document to be retrieved. And, a document retrieving section retrieves the documents based on the retrieval conditions. An effective document search can be performed regardless of the sentence recognition accuracy without requiring higher cost in collecting the required language data.

Disclosed is an accident/near-miss factor area specifying device capable of specifying accident/near-miss factor areas, the presentation of which is highly required. The accident/near-miss factor area specifying device (100) is used for specifying accident/near-miss factor areas which a driver of a vehicle should. be aware of in order to prevent an accident, and the device comprises a viewing area specifying unit (151) for specifying a viewing area of a driver of a vehicle which had a near-miss, immediately before the near-miss occurs, and an unnoticed area specifying unit (152) wherein, when a near-miss object is located in a viewing area, an area corresponding to the position of the object is treated as an unnoticed area which is one of the accident/near-miss factor areas.

A base station authentication method which allows base station authentication to be performed by more wireless terminal apparatuses within a fixed period of time. This method is a base station authentication method for TDMA wireless communication and comprises: a step in which wireless terminal apparatuses (300) select timeslots (S2200) and use the selected timeslots to transmit, to a wireless base station apparatus (200), responses indicating the start of base station authentication (S2300); a step in which the wireless base station apparatus (200) generates base station authentication data summarizing information indicating whether there has been a response for each timeslot, for the plurality of timeslots (S2400), and transmits the generated base station authentication data to the wireless terminal apparatuses (300) (S2500); and a step in which the wireless terminal apparatuses (300) perform base station authentication on the transmission origin of the base station authentication data, based on whether the received base station authentication data indicates that there were responses at the selected timeslots (S2700).
