Abstract

It is an object of the invention to reuse the available part of data in cases where data is determined not to be authentic. The input section inputs the data, and the processing section generates the processed data. According to the generation of the processed data, the authentication data generation section generates the authentication data for authenticating the processed data and the output section outputs the data with authentication wherein the processed data is correlated with the authentication data. By including the data inputted into the processed data, even if the processed data cannot be authenticated, a process can be performed by using the data as long as the authenticity of the data can be guaranteed. Moreover, it becomes possible to specify a flexible process by including the status return information in the processed data required for the process in the case where the authenticity cannot be affirmed.

Claims

1. An information processing apparatus comprising:

an input section for inputting data,

a processing section processing the inputted data and generating the processed data,

an authentication data generation section generating the authentication data according to the generation of the processed data in the processing unit, in which the authentication data is used for guaranteeing the authenticity of the processed data, and

an output section for outputting the data with authentication, a data correlating the processed data with the authentication data.

2. The information processing apparatus as defined in claim 1, wherein the processed data corresponds to the data indicating the completion of the process in the processing unit.

3. The information processing apparatus as defined in claim 1, wherein the input section inputs the data with authentication as the data.

4. The information processing apparatus as defined in claim 3 comprising an authentication section verifying the authenticity of the inputted data with authentication based on the authentication data of the data with authentication that is inputted into the input unit.

5. The information processing apparatus as defined in claim 4 wherein the processing section generates the processed data including the data with authentication that is inputted into the input unit.

6. The information processing apparatus as defined in either claim 4 or 5 wherein the processed data including the status return information that is necessary for the process of the data with authentication in cases where the result of the authentication in the authentication section does not affirm the authenticity of the data with authentication.

7. The information processing apparatus as defined in claim 6 wherein the authentication section verifies the data with authentication that is outputted by the secondary original information processing apparatus, in cases where there exists a secondary original information processing apparatus that has outputted the data with authentication into the primary original information processing apparatus that has outputted the data with authentication, the authenticity of which cannot be affirmed by the authentication unit.

8. The information processing apparatus as defined in claim 7 wherein the status return information corresponds to the information for processing the data with the authentication that has been outputted by the secondary original information processing apparatus, in which said processing is based on the status return information included in the processed data of the secondary original information processing apparatus, in cases where the result of the authentication for the data with authentication that has been outputted by the secondary original information processing apparatus affirms the authenticity of the data with authentication.

9. The information processing apparatus as defined in claim 6 wherein the status return information includes one or more of the URL, telephone number, e-mail address, or program necessary for a process of the data with authentication, the authenticity of which has not been affirmed.

10. An information processing program to cause a computer to execute the following steps:

an input step of acquiring inputted data,

a processing step of processing the acquired data by the input step and of generating processed data,

an authentication data generation step of generating the authentication data according to the generation of the processed data in the processing step, in which the authentication data is used for the guarantee of the authenticity of the processed data, and

an output step of outputting the data with authentication wherein the processed data is correlated with the authentication data.

11. An information processing method comprising the following steps:

an input step of acquiring inputted data,

a processing step of processing the acquired data in the input step and of generating processed data,

an authentication data generation step of generating the authentication data according to the generation of the processed data in the processing step, in which the authentication data is used for the guarantee of the authenticity of the processed data, and

an output step of outputting the data with authentication wherein the processed data is correlated with the authentication data.
