Abstract:
To provide a communication system including a mobile terminal which can prevent leak of information even if the mobile terminal is lost and reproduce previously accumulated confidential data without losing newly created and updated confidential data. A mobile terminal includes connection state judging device which detects a line connection state with a server. When the line connection state is a broadband connection, the data is read directly from and written directly into a data storing device of the server. When the line connection state is a narrowband connection, the data is temporarily read out and written into a data storing device of the terminal. When the operation of the mobile terminal is completed or a security operation starting instruction is issued by a user, the updated confidential data is written into the data storing device of the server and then the confidential data is erased from the mobile terminal.
Abstract:
This invention provides a use authentication control device, a user authentication device, a data processing device, and a user authentication control method and the like that control an authentication interval and an authentication effective period in accordance with a communication speed so as to make it possible to keep a balance between user convenience and safety. The user authentication device, which controls an authentication effective period for a user authentication device of a data processing device connected with a server device through a network, is provided with bandwidth acquiring means for acquiring a communication speed of the network and effective period determining means for determining an authentication effective period in accordance with the communication speed.
Abstract:
In an identification system for electronic commerce, an end terminal transmits a transaction request message containing biometrics data of a user to a communications network, At least one electronic commerce service provider unit is provided which receives the transaction request message via the network and transmits an authentication request message containing the biometrics data to the network. An authentication server having a database for storing registered biometrics data receives the authentication request message and determines whether the received biometrics data has corresponding biometrics data in the database and returns a reply to the ECSP unit via the network indicating that the transaction request message is authenticated if the received biometrics data coincides with one of the registered biometrics data of the database.
Abstract:
An authentication method using biometrics identification, comprising the following steps of: identifying a user by biometrics entered from a portable authentication terminal; when the user has been registered previously, establishing communication between the authentication terminal and an authentication executing device independent of the authentication terminal, and calculating a common secret key for use in transmission of an authentication message; encrypting an authentication message including the user's inherent information in the authentication terminal based on the secret key; sending the encrypted authentication message from the authentication terminal to the authentication executing device; and decrypting the authentication message in the authentication executing device based on the calculated secret key, thereby executing an operation depending on the user. inherent information included in the message.
Abstract:
There is provided a remote operation system, a relay device, a communication device, and a remote operation method which are capable of executing collective remote operations. The remote operation system includes communication devices, an external device that specifies at least one communication device as a target of a remote operation among the communication devices, and accepts an input of a remote operation content to be executed for the specified communication device, and a relay unit for relaying communication between the specified communication devices and the external device. The relay unit includes a storage unit for storing the remote operation content accepted by the external device, and a notification unit for notifying the specified communication device of the remote operation content.
Abstract:
An executed function management system of a mobile terminal, includes a mobile phone terminal configured to store an execution history when an execution history target function, whose execution history should be stored, as one of functions is executed; and a server unit configured to acquire said execution history from the mobile phone terminal to store for every the mobile phone terminal. The mobile phone terminal notifies the execution history to the server unit at said preset timing or when a notice of said execution history is requested from said server unit.

Abstract:
An information terminal apparatus is provided which presents an operation menu according to a target apparatus just by photographing the target apparatus by a built-in camera, thereby intuitively executing operation appropriate for the target apparatus. The information terminal apparatus includes a target recognition unit which recognizes a target apparatus from an image taken by photographing the apparatus by the built-in camera, a menu management unit which presents operation menu information preserved in advance according to the target apparatus based on a recognition result obtained by the target recognition unit, and a processing unit which gives an operation instruction according to operation contents selected based on the operation menu information.
Abstract:
[Problem] To make it possible to prevent certainly user's personal information from flowing out without burdening the user, and to manage sensor information and result information which is acquired through processing a service by use the sensor information, on the basis of importance, classification, personal property, utilization form or the like.[Solution to the problem] A terminal according to the present invention includes an acquisition means to acquire sensor data, a storage means to store a policy table which defines a management policy for each sensor data or each service which uses the sensor data, and a control means to acquire the management policy corresponding to the sensor data or the service with reference to the policy table and to manage the sensor data on the basis of the management policy.
