Abstract
It is an object to provide an information processing apparatus and a data management system which can access data and maintain security even in an environment where the apparatus cannot be connected to a security managing server. To accomplish the object, a secure application discriminates whether or not authentication can be obtained from the managing server. If it is decided that the authentication cannot be obtained from the managing server, a process of secure data is executed in accordance with use restriction information of the data. If it is decided that the authentication can be obtained from the managing server, a process of the data is executed in accordance with access right information from the managing server.
Claims18
An information processing apparatus comprising:
- a discrimination unit adapted to discriminate whether or not authentication can be obtained from a managing server;
- and
- a processing unit adapted to execute a process of data in accordance with use restriction information of the data if it is discriminated by said discrimination unit that the authentication cannot be obtained from the managing server and execute the process of the data in accordance with access right information from the managing server if it is discriminated by said discrimination unit that the authentication can be obtained from the managing server.
An information processing apparatus comprising:
- a discrimination unit adapted to discriminate whether or not authentication can be obtained from a managing server;
- and
- a processing unit adapted to change a temporary data portion of data if it is discriminated by said discrimination unit that the authentication cannot be obtained from the managing server and change a real data portion of the data on the basis of the temporary data portion of the data if it is discriminated by said discrimination unit that the authentication can be obtained from the managing server.
An information processing method comprising:
- a discrimination step of discriminating whether or not authentication can be obtained from a managing server;
- and
- a processing step of executing a process of data in accordance with use restriction information of the data if it is discriminated in said discrimination step that the authentication cannot be obtained from the managing server and executing the process of the data in accordance with access right information from the managing server if it is discriminated in said discrimination step that the authentication can be obtained from the managing server.
An information processing method comprising:
- a discrimination step of discriminating whether or not authentication can be obtained from a managing server;
- and
- a processing step of changing a temporary data portion of data if it is discriminated in said discrimination step that the authentication cannot be obtained from the managing server and changing a real data portion of the data on the basis of the temporary data portion of the data if it is discriminated in said discrimination step that the authentication can be obtained from the managing server.
A program stored in a computer-readable storage medium, comprising:
- a discrimination step of discriminating whether or not authentication can be obtained from a managing server;
- and
- a processing step of executing a process of data in accordance with use restriction information of the data if it is discriminated in said discrimination step that the authentication cannot be obtained from the managing server and executing the process of the data in accordance with access right information from the managing server if it is discriminated in said discrimination step that the authentication can be obtained from the managing server.
A program stored in a computer-readable storage medium, comprising:
- a discrimination step of discriminating whether or not authentication can be obtained from a managing server;
- and
- a processing step of changing a temporary data portion of data if it is discriminated in said discrimination step that the authentication cannot be obtained from the managing server and changing a real data portion of the data on the basis of the temporary data portion of the data if it is discriminated in said discrimination step that the authentication can be obtained from the managing server.
