Mobile terminal, working device, data management system, and recording medium

A working device which receives management object data from a mobile terminal, the working device comprising:

• a local connection requester that locally communicates with the mobile terminal through wired communication or wireless communication;
• a security specification provider that transmits security specification information including security function of the working device to the mobile terminal;
• a management object data receiver that receives the management object data and data management contract information indicating a contract of the management object data from the mobile terminal;
• a security function activator that activates the security function so that the disclosure condition of the management object data is satisfied, based on the data management contract information;
• and
• a data management record transmitter that transmits a management record of the management object data to the mobile terminal locally re-connected through the local connection requester.

A data management system comprising:

• a management server that manages management object data;
• a mobile terminal which communicates with the management server through a network;
• and
• a working device which locally communicates with the mobile terminal through wired communication or wireless communication,
• the management server comprising:
• a management object data provider that provides the management object data and disclosure condition information related to a disclosure condition of the management object data to the mobile terminal, based on a management object data acquisition request from the mobile terminal;
• and
• a data management record receiver that receives a management record of the provided management object data from the mobile terminal,
• the mobile terminal comprising:
• a management object data acquirer that requests the management server to acquire the management object data, and acquires the management object data and the disclosure condition information related to the disclosure condition of the management object data from the management server;
• a local connection receiver that locally communicates with the working device through the wired communication or the wireless communication;
• a security specification acquirer that acquires security specification information related to a security function of the working device;
• a data management contract creator that creates data management contract information indicating a contract related to a management of the management object data of the working device, if it is determined that the working device satisfies the disclosure condition of the management object data, based on the security specification information of the working device which transmits the management object data and the disclosure condition information of the management object data;
• a management object data transmitter that transmits the management object data and the created data management contract information to the working device;
• a data management record receiver that receives the management record of the management object data from the working device that locally communicates by the local connection receiver;
• and
• a data management record transmitter that transmits a management record of the received management object data to the management server, and
• the working device comprising:
• a local connection requester that locally communicates with the mobile terminal through the wired communication or the wireless communication;
• a security specification provider that provides security specification information related to its security function to the mobile terminal;
• a management object data receiver that receives the management object data and data management contract information indicating a contract related to a management of the management object data from the mobile terminal;
• a security function activator that activates the security function so that the disclosure condition of the management object data is satisfied, based on the data management contract information;
• and
• a data management record transmitter that transmits a management record of the management object data to the mobile terminal locally re-connected through the local connection requester.

A data managing method for a data management system having a management server managing management object data, a mobile terminal connected to the management server through a network, and a working device locally connected to the mobile terminal through wired communication or wireless communication, such that data communication is enabled, the data managing method comprising:

• acquiring, at the mobile terminal, the management object data and disclosure condition information related to a disclosure condition of the management object data from the management server;
• locally communicating, at the mobile terminal, with the working device through the wired communication or the wireless communication;
• acquiring, at the mobile terminal, security specification information related to a security function of the working device from the working device;
• creating, at the mobile terminal, data management contract information indicating a contract related to a management of the management object data of the working device, when the working device satisfies the disclosure condition of the management object data, based on the security specification information of the working device and the disclosure condition information of the management object data;
• transmitting the management object data including the created data management contract information from the mobile terminal to the working device;
• activating, at the working device, the security function to satisfy the disclosure condition of the management object data, based on the data management contract information;
• transmitting a management record of the management object data from the working device to the locally communicated mobile terminal;
• and
• transmitting the management record of the management object data received from the working device, from the mobile terminal to the management server.

A compute readable storage medium storing a program, the program causing a computer as a mobile terminal to function as:

• locally communicating with a working device through wired communication or wireless communication;
• holding management object data and disclosure condition information related to a disclosure condition of the management object data;
• acquiring security specification information related to a security function of the working device;
• creating data management contract information indicating a contract related to a management of the management object data at the side of the working device, when the working device satisfies the disclosure condition of the management object data, based on the security specification information of the working device transmitting the management object data and the disclosure condition information applied to the management object data;
• applying the created data management contract information and transmitting the management object data to the working device;
• and
• receiving a management record of the management object data from the locally re-connected working device.
