Abstract

There is provided an apparatus for access right management including a transfer destination determining section that determines a candidate for a group whch, after reorganization, corresponds to a group eliminated due to reorganization, an object determining section that determines an object to which an access right is granted to the eliminated group, a presenting section that presents the candidate to a user, a receiving section that receives from the user an instruction indicating whether or not to transfer, to the candidate, the access right of the eliminated group to the object, and an updating section that updates an access right regarding the object according to the instruction received from the user.

Claims

1. An apparatus for access right management, comprising:

a transfer destination determining section that determines a candidate for a group which, after reorganization, corresponds to a group eliminated due to reorganization;

an object determining section that determines an object to which an access right is granted to the eliminated group;

a presenting section that presents the candidate to a user;

a receiving section that receives from the user an instruction indicating whether or not to transfer, to the candidate, the access right of the eliminated group to the object; and

an updating section that updates an access right regarding the object according to the instruction received from the user.

2. The apparatus according to claim 1, wherein

the transfer destination determining section determines the candidate based on a comparison of members of the eliminated group and members of each group present after reorganization.

3. The apparatus according to claim 1, wherein

the transfer destination determining section determines, as a candidate, a group after reorganization in which a proportion of members of the eliminated group with respect to all members of the group is greater than a value.

4. The apparatus according to claim 1, wherein

if the eliminated group is a group to which the owner of the object belongs, a group to which the owner belongs after reorganization is determined to be a candidate.

5. The apparatus according to claim 1, further comprising:

a section that updates the access right regarding the object by transferring the access right granted to the eliminated group to the candidate if the instruction has not been received from the user for a period.

6. A method for access right management, comprising:

determining a candidate for a group which, after reorganization, corresponds to a group eliminated due to reorganization;

determining an object to which an access right is granted to the eliminated group;

presenting the candidate to an user;

receiving from the user an instruction indicating whether or not to transfer, to the candidate, the access right of the eliminated group to the object; and

updating an access right regarding the object according to the instruction.

7. The method according to claim 6, wherein

the candidate is determined based on a comparison of members of the eliminated group and members of each group present after reorganization.

8. The method according to claim 6, wherein

a group after reorganization in which a proportion of members of the eliminated group with respect to all members of the group is greater than a value is determined to be a candidate.

9. The method according to claim 6, wherein,

if the eliminated group is a group to which the owner of the object belongs, a group to which the owner belongs after reorganization is determined to be a candidate.

10. The method according to claim 6, further comprising:

updating the access right regarding the object by transferring the access right granted to the eliminated group to the candidate if the instruction has not been received from the user for a period.

11. A storage medium readable by a computer, the storage medium storing a program of instructions executable by the computer to perform a function for access right management, the function comprising:

determining a candidate for a group which, after reorganization, corresponds to a group eliminated due to reorganization;

determining an object to which an access right is granted to the eliminated group;

presenting the candidate to an user;

receiving from the user an instruction indicating whether or not to transfer, to the candidate, the access right of the eliminated group to the object; and

updating an access right regarding the object according to the instruction.

12. The storage medium according to claim 11, wherein

the candidate is determined based on a comparison of members of the eliminated group and members of each group present after reorganization.

13. The storage medium according to claim 11, wherein

a group after reorganization in which a proportion of members of the eliminated group with respect to all members of the group is greater than a value is determined to be a candidate.

14. The storage medium according to claim 11, wherein

if the eliminated group is a group to which the owner of the object belongs, a group to which the owner belongs after reorganization is determined to be a candidate.

15. The storage medium according to claim 11, the function further comprising:

updating the access right regarding the object by transferring the access right granted to the eliminated group to the candidate if the instruction has not been received from the user for a period.
