Abstract

A method, system and token are described which control access to a token server system. In a first aspect, a method and system for controlling access to a file system of a token server comprise encoding a time specific permission into a token. In a second aspect, a token server system comprises at least one client and a token server accessible by the at least one client. The token server provides a token to the at least one client to allow the client to have access to the data on the token server. The token includes a time specific permission. In a third aspect, a token for use in a token server system comprises a group of privileges and security identifiers. The token includes a time specific permission. A system and method in accordance with the present invention controls access to networked systems, but does not totally disable or change a system to accommodate temporary outages of access. Individual groups could have different targeted functions (read, write, or execute) tied to different time blocks within a system. The token is not all or nothing, but instead provides finer granularity of function and time for security and access to data.

Claims

1. A method for controlling access to a file system of a token server, the method comprising:

(a) encoding a time specific permission into a token;

(a1) encoding a database within the token; and

(a2) providing a look-up table of exceptions, and inclusions of functions within the database, the exceptions and inclusions of functions being tied to specific time periods.

2. The method of claim 1 including the step of (b) providing the encoded token to an appropriate user.

3. The method of claim 1 wherein functions can be targeted to different time periods within the time encoded specific permission.

4. The method of claim 3 wherein the different functions can include any one of a read, write and execute command.

5. A token server system comprising:

at least one client; and

a token server accessible by the at least one client the server for providing a token to the at least one client for allowing the at least one client to have access to data on the token server;

the token including an encoded time specific permission, wherein the encoded token comprises;

a database; and

a look-up table of exceptions, and inclusions of functions within the database, the exceptions and inclusions of functions being tied to specific time periods.

6. The token server system of claim 5 wherein functions can be targeted to different time periods within the time specific permission.

7. The token server system of claim 6 wherein the different functions can include any one of a read, write and execute command.

8. A computer readable medium containing program instructions for controlling access to a file system of a token server, the program instructions for:

(a) encoding a time specific permission into a token;

(a1) encoding a database within the token; and

(a2) providing a look-un table of exceptions, and inclusions of functions within the database, the exceptions and inclusions of functions being tied to specific time periods.

9. A computer readable medium containing program instructions of claim 8 including program instructions for providing the encoded token to an appropriate user.

10. The computer readable medium containing program instructions of claim 8 wherein functions can be targeted to different time periods within the time specific permission.

11. The computer readable medium containing program instructions of claim 10 wherein the different functions can include any one of a read command, a write command and one execute command.

12. A system for controlling access to a file system of a token server comprising:

means for encoding a time specific permission into a token;

means for encoding a database within the token; and

means for providing a look-up table of exceptions, and inclusions of functions within the database, the exceptions and inclusions of functions being tied to specific time periods.

13. The system of claim 12 which includes means for providing the encoded token to an appropriate user.

14. The system of claim 12 wherein functions can be targeted to different time periods within the time specific permission.

15. The system of claim 14 wherein the different functions can include any one of a read command, a write command, and an execute command.
