Abstract

An information system enables an information device to achieve its functions fully by acting for the information device. The information device generates a service code by encoding or encrypting a terminal ID and a service ID corresponding to a target service using a time seed that is updated regularly, and transmits the service code to the server. The server decodes the terminal ID and the service ID from the service code according to a time seed replica generated in synchronism with the time seed in the information device, which is updated regularly. This enables the server to identify the service and the information device that receives the service, thereby preventing an unauthorized access. The service provider executes the service corresponding to the decoded service ID, and the user of the information device can receive the service, and confirm that the service is carried out via a communication medium.

Claims

1. An information device comprising:

a time seed generating section for generating a time seed that is updated regularly;

a target service information input section for inputting information about a target service; and

a service code generating section for generating a service code by encoding or encrypting a terminal ID and a service ID using the time seed, wherein the terminal ID is assigned to said information device for identifying said information device, the service ID corresponds to the information input from said target service information input section, and the time seed is generated by said time seed generating section.

2. The information device as claimed in claim 1, further comprising an external information processing section for capturing external information corresponding to the generated service code, and for carrying out processing of the external information.

3. The information device as claimed in claim 2, wherein said external information processing section comprises a receiver for receiving the external information from a medium that transmits the external information.

4. An information processing unit comprising:

a decoding section for decoding a terminal ID and a service ID from a service code according to a time seed replica, wherein the service code is generated by an information device that encodes or encrypts, by using a time seed updated regularly, the terminal ID for identifying the information device and the service ID corresponding to information associated with a target service, and the time seed replica is updated regularly in synchronization with the time seed; and

a control section for controlling a processing associated with execution of a service corresponding to the decoded service ID, and for sending a result of the service processing to the information device via the communication medium according to the decoded terminal ID.

5. A deputy information processing method comprising the steps of:

generating a service code by encoding or encrypting a terminal ID and a service ID by an information device using a time seed that is updated regularly, the terminal ID being assigned to the information device for identifying it and the service ID corresponding to information associated with a target service;

sending the service code generated and output by said information device to an information processing unit via a communication section;

decoding the terminal ID and the service ID from the service code sent to said information processing unit according to a time seed replica that is updated regularly in synchronization with the time seed in the information device;

controlling a processing of a service corresponding to the decoded service ID in said information processing unit; and

transmitting a result of the service processing from said information processing unit to said information device via the communication section according to the decoded terminal ID.

6. The deputy information processing method as claimed in claim 5, wherein when the decoded service ID is a service that requires voice information for controlling the service processing, said information processing unit connects voice communication enabling means to the communication section used for sending the service code.

7. The deputy information processing method as claimed in claim 5, wherein the communication section used for sending the service code is a public network capable of transmitting voice information.

8. The deputy information processing method as claimed in claim 5, wherein the communication section used for sending the service result to the information device includes a public network for transmitting the service processing result.

9. The deputy information processing method as claimed in claim 6, wherein the communication section used for sending the service result to the information device includes a public network for transmitting the service processing result.

10. The deputy information processing method as claimed in claim 7, wherein the communication section used for sending the service result to the information device includes a public network for transmitting the service processing result.
