Device and management module

A management module installed in a device holding control target data inside the device, the management module comprising:

• a state management unit configured to manage a life cycle state that the device is presently in;
• a user authentication unit configured to receive authentication data, authenticate a user, and give a response indicating a role of the user;
• an access control unit configured to
• acquire a present life cycle state from the state management unit when an access request to access the control target data is received,
• authenticate the user by the user authentication unit and acquire the role of the authenticated user,
• acquire access possibility information based on the present life cycle state and the role of the user who has made the access request, the access possibility information being acquired from a state access control policy associated with the control target data, and
• control access to the control target data based on the access possibility information;
• and
• an access prohibiting unit configured to perform a process of comparing at least one of a position and a time allowed in operation plan information with at least one of a present position and a present time at a predetermined timing, and prohibiting access to the control target data when at least one of the position and the time allowed in the operation plan information does not match at least one of the present position and the present time, based on the operation plan information in which life cycle states are associated with at least one of positions and times that are allowed for state transitions of the life cycle states.

A non-transitory computer-readable recording medium storing a program that causes a computer that constitutes a management module installed in a device holding control target data inside the device, to execute a process comprising:

• managing a life cycle state that the device is presently in;
• receiving authentication data, authenticating a user, and giving a response indicating a role of the user;
• acquiring a present life cycle state managed at the managing when an access request to access the control target data is received;
• authenticating the user and acquiring the role of the authenticated user;
• acquiring access possibility information based on the present life cycle state and the role of the user who has made the access request, the access possibility information being acquired from a state access control policy associated with the control target data;
• controlling access to the control target data based on the access possibility information;
• and
• performing a process of comparing at least one of a position and a time allowed in operation plan information with at least one of a present position and a present time at a predetermined timing, and prohibiting access to the control target data when at least one of the position and the time allowed in the operation plan information does not match at least one of the present position and the present time, based on the operation plan information in which life cycle states are associated with at least one of positions and times that are allowed for state transitions of the life cycle states.
