Security for future log-on location

1. A method of authenticating user log-on to a network, the method comprising:

determining a current log-on location for a user utilizing user information in a network, wherein the log-on is based on log-on credentials;

analyzing user information in the network for potential future log-on location information, wherein the potential future log-on location information comprises information provided after log-on authentication and before user access to network resources, and the potential future location information comprises user entered next location information that is explicitly entered at a log-on time or previously entered after log-on authentication of a previous network session in response to a query or a dropdown menu;

determining a location of a subsequent log-on attempt based on said log-on credentials;

authenticating said subsequent log-on attempt based on said potential future log-on location information; and

authorizing said subsequent log-on attempt if said authentication is successful.

2. The method of claim 1 , wherein at least one portion of the user information in the network comprising user entered text.

3. The method of claim 1 , wherein the user entered next location information is explicitly entered at a logout time of a previous network session in response to a text query or dropdown menu.

4. The method of claim 1 , wherein the potential future location information is entered via at least one communication with at least one other user or from a calendar application.

5. The method of claim 1 , wherein the network comprising a social network.

6. The method of claim 1 , further comprising:

validating the next log-on based on comparing current log-on location information with the potential future location information.

7. A computer program product for authenticating network log-on, the computer program product comprising:

a computer readable storage device having computer usable program code embodied therewith, the computer usable code comprising:

computer usable program code configured to determine current location based on user information in a network, and to determine a location of a next log-on to the network;

computer usable program code configured to analyze at least one portion of the network for potential future location information, wherein the potential future location information comprises information provided after log-on authentication and before user access to network resources, and the potential future location information comprises user entered next location information that is explicitly entered at a log-on time or previously entered after log-on authentication of a previous network session in response to a text query or a dropdown menu; and

computer usable program code configured to authenticate the next log-on to the network based on the potential future location information.

8. The computer program product of claim 7 , wherein the at least one portion of the network comprising user entered text.

9. The computer program product of claim 7 , wherein the potential future location information is entered via at least one communication with at least one other user or from a calendar application.

10. The computer program product of claim 7 , further comprising computer useable program code configured to validate the next log-on based on comparing current log-on location information with the potential future location information.

11. A system comprising:

at least one client configured for logging in a user to a network;

at least one server device coupled to the network, the server device:

determines current location based on user information in the network, and for determining a location of a next log-on of the user to the network,

analyzes at least one portion of the network for potential future location information for the user, wherein the potential future location information comprises user entered next location information that is explicitly entered at a log-on time or previously entered after log-on authentication of a previous network session in response to a text query or a dropdown menu, and

authenticates the next log-on of the user to the network based on the potential future location information, wherein the potential future log-on location information comprises information provided after log-on authentication and before user access to network resources.

12. The system of claim 11 , wherein the at least one portion of the network comprising user entered text.

13. The system of claim 11 , wherein the potential future location information is entered via at least one communication between the user and at least one other user or from a calendar application.

14. The system of claim 11 , wherein the server validates the next log-on based on comparing current log-on location information with the potential future location information.
