Abstract

A data management system includes a detecting apparatus that detects an information processing apparatus and a server apparatus that controls access to data by the information processing apparatus. The detecting apparatus detects the information processing apparatus located within a predetermined area. The server apparatus includes a transmitter that transfers data to the detected information processing apparatus, the data being associated with access authority indicating whether or not the information processing apparatus is allowed to access the data, and circuitry that controls an access to the data from the detected information processing apparatus in accordance with the access authority associated with the data.

First claim

The invention claimed is:

1. A data management apparatus, comprising:
circuitry configured to:
determine whether an information processing apparatus is located within a predetermined area; and
receive data together with access authority information indicating whether the information processing apparatus is allowed to store or copy the data when the information processing apparatus is determined as located outside the predetermined area;
transmit the data to the information processing apparatus in response to a request consistent with the access authority information; and
after the data is transmitted to the information processing apparatus and when the access authority information indicates that the information processing apparatus is not allowed to store or copy the data when the information processing apparatus is determined as located outside the predetermined area, cause the information processing apparatus to
determine whether the information processing apparatus is located outside the predetermined area, and
delete the data transmitted to the information processing apparatus when the information processing apparatus is determined as located outside the predetermined area;
wherein the data corresponds to providing a video, and
the data management apparatus further comprises a display configured to display the video provided by the data:
wherein information regarding the access authority information is embedded in the video, and the circuitry is configured to
capture an image from the video displayed by the display, and
extract the access authority information from the captured image.

2. The data management apparatus according to claim 1 , wherein the circuitry is further configured to prohibit the information processing apparatus from copying the transmitted data.

3. The data management apparatus according to claim 1 , wherein the circuitry is further configured to prohibit transmitting the data to the information processing apparatus when the information processing apparatus is determined as located outside the predetermined area.

4. The data management apparatus according to claim 1 , wherein the circuitry is further configured to:
transmit notification messages at a predetermined interval, the notification messages causing the information processing apparatus to determine that the information processing apparatus is located outside the predetermined area when the information processing apparatus, within a predetermined period of time after receiving one of the transmitted notification messages, fails to receive another notification message from the data management apparatus.

5. The data management apparatus according to claim 1 , wherein the circuitry is further configured to:
receive notification messages from the information processing apparatus; and
transmit reply messages in response to the received notification messages, respectively, the reply messages causing the information processing apparatus to determine that the information processing apparatus is located outside the predetermined area when the information processing apparatus, within a predetermined period of time after receiving one of the transmitted reply messages, fails to receive another reply message from the data management apparatus.

6. A method of managing data for a data management apparatus, the method comprising:
determining, by circuitry of the data management apparatus, whether an information processing apparatus is located within a predetermined area;
receiving data together with access authority information indicating whether the information processing apparatus is allowed to store or copy the data when the information processing apparatus is determined as located outside the predetermined area;
transmitting data to the information processing apparatus in response to a request consistent with the access authority information; and
after the data is transmitted to the information processing apparatus and when the access authority information indicates that the information processing apparatus is not allowed to store or copy the data when the information processing apparatus is determined as located outside the predetermined area, causing, by the circuitry of the data management apparatus, the information processing apparatus to
determine whether the information processing apparatus is located outside the predetermined area, and
delete the data transmitted to the information processing apparatus when the information processing apparatus is determined as located outside the predetermined area;
wherein the data corresponds to providing a video, and
the data management apparatus further comprises a display configured to display the video provided by the data;
wherein information regarding the access authority information is embedded in the video, and the method further comprises
capturing an image from the video displayed by the display, and
extracting the access authority information from the captured image.

7. A non-transitory, computer-readable recording medium storing a program that, when executed by one or more processors, causes the one or more processors to implement a method of managing data for a data management apparatus, comprising:
determining whether an information processing apparatus is located within a predetermined area;
receiving data together with access authority information indicating whether the information processing apparatus is allowed to store or copy the data when the information processing apparatus is determined as located outside the predetermined area;
transmitting data to the information processing apparatus in response to a request consistent with the access authority information; and
after the data is transmitted to the information processing apparatus and when the access authority information indicates that the information processing apparatus is not allowed to store or copy the data when the information processing apparatus is determined as located outside the predetermined area, causing the information processing apparatus to
determine whether the information processing apparatus is located outside the predetermined area, and
delete the data transmitted to the information processing apparatus when the information processing apparatus is determined as located outside the predetermined area;
wherein the data corresponds to providing a video, and
the data management apparatus further comprises a display configured to display the video provided by the data;
wherein information regarding the access authority information is embedded in the video, and the method further comprises
capturing an image from the video displayed by the display, and
extracting the access authority information from the captured image.
