Abstract
To provide a system which allows large volumes of data to be exchanged efficiently through network connections using portable terminals. An example data communications system includes a data terminal which stores certain data; and an operation terminal which controls access rights to the data stored in the data terminal, in which the operation terminal grants another operation terminal access rights to desired data. The data terminal returns the data according to an access request made based on the access rights. On the other hand, the operation terminal passes the acquired access rights to the data terminal, which then accesses the data terminal via a high-speed, stable, wired network and acquires the desired data, based on the access rights.
Claims28
A data communications system, comprising:
- a data storage terminal to store certain data;
- and
- a control terminal to control access rights to said data stored in said data storage terminal,
- wherein said control terminal connects to another terminal via a network and grants said another terminal access rights to said data, and
- said data storage terminal returns said data according to an access request which is made based on the access rights granted by said control terminal.
A data communications system comprising:
- an operation terminal to make an arrangement about transfer of data held by a designated terminal and acquires access rights to the data based on the arrangement;
- and
- a data acquisition terminal to acquire the data held by said designated terminal by making a data access request to said designated terminal via a network based on said access rights acquired by said operation terminal.
A data communications system, comprising:
- an operation terminal which uses content data;
- and
- a data supply terminal which supplies said content data to said operation terminal,
- wherein said operation terminal requests said data supply terminal to acquire content data held by a designated terminal on a network, and
- said data supply terminal acquires said content data from said designated terminal in possession of said content data and supplies it to said operation terminal, via said network in response to the acquisition request from said operation terminal.
A terminal which conducts data communications via a network, comprising:
- a communications unit which establishes a connection with another terminal via said network;
- and
- an access right granting unit which makes an arrangement via said communications unit about transfer of data held by a designated data storage terminal and grants the other terminal access rights to the data, based on the arrangement.
A terminal which conducts data communications via a network, comprising:
- an access right acquisition unit which makes an arrangement about transfer of data held by a designated data storage terminal with another terminal via said network, and acquires access rights to the data based on the arrangement;
- and
- a data acquisition requesting unit which requests a data acquisition terminal accessible to said data storage terminal via a network to acquire said data based on said acquired access rights.
A data communications method, comprising the steps of:
- making an arrangement via a wireless network about transfer of designated data,
- assigning access rights to the data based on the arrangement;
- and
- transferring said data between designated terminals over a wired network based on the assigned access rights.
A program comprising code for controlling a computer which conducts data communications via a network and implementing in the computer the functions of:
- establishing a connection with another terminal via said network;
- making an arrangement about transfer of data held by a designated data storage terminal with another terminal via said network, and
- granting said another terminal access rights to the data, based on the arrangement.
A program for controlling a computer which conducts data communications via a network and implementing in the computer the functions of:
- making an arrangement with another terminal about transfer of data held by a designated data storage terminal via said network,
- acquiring access rights to the data based on the arrangement;
- and
- requesting a data acquisition terminal accessible to said data storage terminal via a network to acquire said data based on said acquired access rights.
A recording medium including a program for controlling a computer which conducts data communications via a network, said program being stored in a format readable by the computer, wherein said program makes said computer function as:
- an access right granting unit which makes an arrangement about transfer of data held by a designated data storage terminal with another terminal via said network and grants the other terminal access rights to the data, based on the arrangement;
- and
- a notification unit which notifies said data storage terminal of the arrangement with said other terminal.
A recording medium including a program for controlling a computer which conducts data communications via a network, said program being stored in a format readable by the computer, wherein said program makes said computer function as:
- an access right acquisition unit which makes an arrangement about transfer of data held by a designated data storage terminal with another terminal via said network and acquires access rights to the data based on the arrangement;
- and
- a data acquisition requesting unit which requests a data acquisition terminal accessible to said data storage terminal via a network to acquire said data based on said acquired access rights.
