Abstract

Terminal information of a user terminal requesting a log-in is acquired, a log-in procedure to be applied to the user terminal is determined based on the terminal information, a log-in operation based on the determined log-in procedure is accepted, and the log-in from the user terminal is permitted when the log-in operation is right.

Claims

1. An authentication information processing method comprising:

acquiring apparatus information of a user apparatus requesting a log-in;

determining a log-in procedure to be applied to the user apparatus on the basis of the apparatus information;

accepting a log-in operation from the user apparatus; and

judging, based on the determined log-in procedure and on the accepted log-in operation, whether the log-in from the user apparatus is permitted or not.

2. An authentication information processing method according to claim 1, further comprising storing an accumulated log-in count from the user apparatus with the log-in count related to the apparatus information, wherein in determining the log-in procedure, the log-in procedure is determined in accordance with the accumulated log-in count.

3. An authentication information processing method according to claim 1, further comprising storing a last log-in time from the user apparatus with the last log-in time related to the apparatus information, wherein in determining the log-in procedure the log-in procedure is determined in accordance with a period elapsed since the last log-in time.

4. An authentication information processing method according to claim 3, further comprising determining a security level for the user apparatus by referring to any one of the apparatus information, the accumulated log-in count and the elapsed period, wherein in determining the log-in procedure the log-in procedure is determined in accordance with the security level.

5. An authentication information processing device comprising:

apparatus information acquiring module acquiring apparatus information of a user apparatus requesting a log-in;

log-in procedure determining module determining a log-in procedure to be applied to the user apparatus on the basis of the apparatus information;

log-in accepting module accepting a log-in operation from the user apparatus; and

log-in judging module judging, based on the determined log-in procedure and on the accepted log-in operation, whether the log-in from the user apparatus is permitted or not.

6. An authentication information processing device according to claim 5, further comprising accumulated log-in count storing module storing an accumulated log-in count from the user apparatus with the accumulated log-in count related to the apparatus information, wherein the log-in judging module determines to the log-in procedure in accordance with the accumulated log-in count.

7. An authentication information processing device according to claim 5, further comprising last log-in time storing module storing a last log-in time to be applied to the user apparatus with the last log-in time related to the apparatus information, wherein the log-in procedure judging module determines the log-in procedure in accordance with a period elapsed since the last log-in time.

8. An authentication information processing device according to claim 7, further comprising security level determining module determining a security level for the user apparatus by referring to any one of the apparatus information, the accumulated log-in count and the elapsed period, wherein the log-in procedure determining means determines the log-in procedure in accordance with the security level.

9. A storage medium that stored an authentication information processing program making a computer process authentication information, the program comprising:

acquiring apparatus information of a user apparatus requesting a log-in;

determining a log-in procedure to be applied to the user apparatus on the basis of the apparatus information;

accepting a log-in operation from the user apparatus; and

judging, based on the determined log-in procedure and on the accepted log-in operation, whether the log-in from the user apparatus is permitted or not.

10. A storage medium that stored an authentication information processing program according to claim 9, further comprising storing an accumulated log-in count from the user apparatus with the accumulated log-in count related to the apparatus information, wherein in determining the log-in procedure the log-in procedure is determined in accordance with the accumulated log-in count.

11. A storage medium that stored an authentication information processing program according to claim 9, further comprising storing a last log-in time from the user apparatus with the last log-in time related to the apparatus information, wherein in determining the log-in procedure the log-in procedure is determined in accordance with a period elapsed since the last log-in time.

12. A storage medium that stored an authentication information processing program according to claim 11, further comprising determining a security level for the user apparatus by referring to any one of the apparatus information, the accumulated log-in count and the elapsed period, wherein in determining the log-in procedure a security level is determined by referring to the security level.
