Information processing apparatus and service providing system

1 . An information processing apparatus comprising:

a storage device configured to store at least first authentication information for authenticating users of the information processing apparatus; and

a processor configured to:

acquire, from a remote apparatus connected by a communication line via a firewall, second authentication information for authenticating the users at the remote apparatus and specified information that specifies a rule for authentication of the users at the remote apparatus not located within the firewall in which the information processing apparatus is located;

synchronize the first authentication information and second authentication information stored in the remote apparatus, by transmitting a part of the first authentication information compliant with the specified information among the first authentication information to the remote apparatus, wherein the first authentication information and the second authentication information are different; and

for a remaining part of the first authentication information which does not comply with the specified information, as long as the remaining part of the first authentication information satisfies a specific condition which is predetermined, transmit also the remaining part of the first authentication information that does not comply with the specified information to the remote apparatus.

2 . The information processing apparatus according to claim 1 , wherein the processor is configured to:

transmit, to the remote apparatus, a deletion instruction for causing the remote apparatus to delete the second authentication information corresponding to the remaining part of the first authentication information that does not comply with the specified information and does not satisfy the specific condition, among the first authentication information.

3 . The information processing apparatus according to claim 1 ,

wherein the specific condition is a condition that the first authentication information is associated with third authentication information issued by an authentication apparatus installed outside the firewall.

4 . The information processing apparatus according to claim 2 ,

wherein the specific condition is a condition that the first authentication information is associated with third authentication information issued by an authentication apparatus installed outside the firewall.

5 . The information processing apparatus according to claim 1 , wherein the processor is configured to:

even in a case where the part of the first authentication information complies with the specified information, as long as a user associated with the first authentication information satisfies a predetermined specific condition, not transmit the first authentication information that complies with the specified information to the remote apparatus.

6 . The information processing apparatus according to claim 5 ,

wherein the specific condition is defined using at least one of a predetermined condition regarding an affiliation destination of the user, a predetermined condition regarding a position of the user, or a predetermined condition regarding a frequency of use of functions provided by the information processing apparatus.

7 . A service providing system comprising:

a local apparatus that includes a first processor which is connected by a communication line to a remote apparatus via a firewall and is installed inside the firewall; and

the remote apparatus that includes a second processor and is installed outside the firewall, wherein

the first processor is configured to:

acquire, from the remote apparatus connected by the communication line via the firewall, second authentication information for authenticating the users at the remote apparatus and specified information that specifies a rule for authentication of the users at the remote apparatus;

synchronize the first authentication information and second authentication information stored in the remote apparatus, by transmitting a part of the first authentication information compliant with the specified information among the first authentication information to the remote apparatus, wherein the first authentication information and the second authentication information are different; and

for a remaining part of the first authentication information which does not comply with the specified information, as long as the remaining part of the first authentication information satisfies a specific condition which is predetermined, transmit also the remaining part of the first authentication information that does not comply with the specified information to the remote apparatus.

8 . The service providing system according to claim 7 , wherein

the first processor is configured to:

transmit, to the remote apparatus, the remaining part of the first authentication information that does not comply with the specified information and does not satisfy the specific condition, among the first authentication information, and

the second processor is configured to:

delete the second authentication information corresponding to the first authentication information, in a case of receiving the remaining part of the first authentication information that does not comply with the specified information and does not satisfy the specific condition, from the local apparatus.

9 . The service providing system according to claim 7 ,

wherein the specific condition is a condition that the first authentication information is associated with third authentication information issued by an authentication apparatus installed outside the firewall.

10 . The service providing system according to claim 8 ,

wherein the specific condition is a condition that the first authentication information is associated with third authentication information issued by an authentication apparatus installed outside the firewall.

11 . The service providing system according to claim 7 , wherein the first processor is configured to:

even in a case where the remaining part of the first authentication information complies with the specified information, as long as a user associated with the first authentication information satisfies a predetermined specific condition, not transmit the remaining part of the first authentication information that complies with the specified information to the remote apparatus.

12 . The service providing system according to claim 11 ,

wherein the specific condition is defined using at least one of a predetermined condition regarding an affiliation destination of the user, a predetermined condition regarding a position of the user, or a predetermined condition regarding a frequency of use of functions provided by the local apparatus.

13 . An information processing apparatus comprising:

means for storing at least first authentication information for authenticating users of the information processing apparatus;

means for acquiring, from a remote apparatus connected by a communication line via a firewall, second authentication information for authenticating the users at the remote apparatus and specified information that specifies a rule for authentication of the users at the remote apparatus not located within the firewall in which the information processing apparatus is located;

means for synchronizing the first authentication information and second authentication information stored in the remote apparatus, by transmitting a part of the first authentication information compliant with the specified information among the first authentication information to the remote apparatus, wherein the first authentication information and the second authentication information are different; and

means for transmitting, for a remaining part of the first authentication information which does not comply with the specified information, as long as the remaining part of the first authentication information satisfies a specific condition which is predetermined, also the remaining part of the first authentication information that does not comply with the specified information to the remote apparatus.
