Embodiment Construction

[0135]As described above, the present embodiment enables the following effects to be obtained.

[0136]In the embodiment, authentication by the management server 30 and acquisition of path information from the management server 30 are performed using a communication terminal 50 such as a mobile phone, a smart phone, or a tablet terminal. Thus, even when the terminal device 10 is in offline environment, the user is able to use protected documents on the terminal device 10 without connecting online. Also, because path information is transmitted from the management server 30, protected documents can be used based on the latest rights policy information. Furthermore, even in the case where the rights policy is changed after creation of a protected document, the change can be reflected.

[0137]In the present embodiment, at the time of using a protected document, a random number can be included in authentication-use information that is transmitted to the management server 30, and this random numb

Abstract

A document authority management system 100 includes a management server 30 that issues path information for document usage based on rights policies, a terminal device 10 that performs document protection based on rights policies and requests the management server 30 to issue path information when document usage is sought, and a communication terminal 50 configured to communicate wirelessly with the management server. The terminal device 10, upon document usage being sought in an offline state, creates authentication-use information for requesting issuance of path information, in a form supported by the communication terminal 50. The communication terminal 50 receives the authentication-use information, transmits the received authentication-use information to the management server 30, and, upon path information being transmitted thereto, changes the path information into a form supported by the terminal device 10.
