Abstract

Information processing apparatus that can improve the convenience of data sharing. A portable apparatus has a voice call function implemented by a voice call block and a data storage function implemented by a shared data storage block. A voice call destination information output block identifies the destination of a voice call, when the voice call block and the voice call function of the information processing apparatus start the voice call, and outputs voice call destination identification information identifying the voice call destination. Receiving the identification information output by the voice call destination information output block, an access control block judges whether the received identification information is included in access control information stored in an access control information storage block. If the voice call destination identification information is included in the access control information, the access control block permits the information processing apparatus to access the shared area through a network.

Claims

1. An information processing apparatus that can be connected to a peer information processing apparatus through a network, the information processing apparatus comprising:

a voice call block which performs a voice call by phone;

a shared data storage block which provides a shared area for storing data to be shared with the peer information processing apparatus;

an access control information storage block which stores access control information defining the peer information processing apparatus permitted to access the shared area through the network, by associating it with voice call destination identification information for identifying at least the destination of the voice call;

a voice call destination information output block which outputs the voice call destination identification information in accordance with the destination of the voice call when the voice call block starts the voice call; and

an access control block which performs judgment of whether the voice call destination identification information output by the voice call destination information output block is included in the access control information stored in the access control information storage block and, if the voice call destination identification information is included, permits the peer information processing apparatus corresponding to the voice call destination identification information to access the shared area through the network.

2. The information processing apparatus according to claim 1, wherein the access control block prohibits the shared area from being accessed when the voice call by the voice call block ends.

3. The information processing apparatus according to claim 1, wherein the shared data storage block has a plurality of shared areas;

the access control information storage block stores the access control information specifying the voice call destination identification information corresponding to the peer information processing apparatus which is permitted to access each of the plurality of shared areas; and

the access control block makes the judgment in accordance with the access control information corresponding to each of the plurality of shared areas.

4. The information processing apparatus according to claim 1, comprising:

a first information processing block; and

a second information processing block which can operate in parallel with the first information processing block;

wherein;

the first information processing block implements the voice call block and the voice call destination information output block;

the second information processing block implements the access control information storage block and the access control block; and

the shared data storage block is connected to the second information processing block.

5. The information processing apparatus according to claim 1, wherein the voice call destination identification information is a telephone number of the destination of the voice call;

and

as the access control information, address information on the network of the peer information processing apparatus to access the shared area and the telephone number are stored in association with each other.

6. The information processing apparatus according to claim 5, wherein the access control block receives the address information from the peer information processing apparatus requesting to access the shared area and judges whether to permit its access in accordance with the access control information, during the voice call by the voice call block.

7. The information processing apparatus according to claim 1, wherein the voice call block implements a function to make a voice call through the network by connecting to the network;

and

the voice call destination identification information is address information on the network, of the destination of the voice call by the voice call block.

8. The information processing apparatus according to claim 1, wherein the information processing apparatus is a portable apparatus.

9. A data sharing method of an information processing apparatus that can be connected to a peer information processing apparatus through a network, the data sharing method comprising:

performing a voice call by phone by a voice call block;

providing a shared area for storing data to be shared with the peer information processing apparatus, by a shared data storage block;

outputting voice call destination identification information identifying a voice call destination in accordance with the destination of the voice call when the voice call block starts the voice call, by a voice call destination information output block; and

judging whether the voice call destination identification information output by the voice call destination information output block is included in access control information stored in an access control information storage block, the access control information defining the peer information processing apparatus permitted to access the shared area through the network, by associating it with the voice call destination identification information for identifying at least the destination of the call and, if the voice call destination identification information is included, permitting the peer information processing apparatus corresponding to the voice call destination identification information to access the shared area through the network, by an access control block.

10. A computer readable medium having stored thereon a data sharing program for controlling access to a shared area for storing data to be shared with a peer information processing apparatus, the shared area being provided by a shared data storage block in a computer, the data sharing program causing the computer to execute the steps of:

outputting voice call destination identification information identifying the destination of a voice call in accordance with the destination of the voice call when a voice call block of the computer starts the voice call;

judging whether the output voice call destination identification information is included in access control information defined by associating the peer information processing apparatus permitted to access the shared area through a network with the voice call destination identification information identifying at least the destination of the voice call; and

permitting the peer information processing apparatus corresponding to the voice call destination identification information to access the shared area through the network, if it is judged that the voice call destination identification information is included.
