Abstract

To prevent conflicts of interest, an information management system is used to make sure two or more groups are kept apart so that information does not circulate freely between these groups. The system has policies to implement an “ethical wall” to separate users or groups of users. The user or groups of user may be organized in any arbitrary way, and may be in the same organization or different organizations. The two groups (or two or more users) will not be able to access information belonging to the other, and users in one group may not be able to pass information to the other group. The system may manage access to documents, e-mail, files, and other forms of information.

Claims

1. A method of managing information comprising:

providing an organization, wherein the organization has an information management system comprising a policy server comprising one or more rules to manage information of the organization;

providing a first user of the organization and a first document managed by the information management system;

when the first user attempts to access the first document at a first computer, seeking approval from the policy server by evaluating a first rule of the one or more rules to manage information, wherein the first rule is created before the first document and the first rule comprises a first conditional statement and a first abstraction component, the first abstraction component stored separately from the first rule at a second computer different than the first computer and the first abstraction component comprises a second conditional statement, and wherein evaluating the first rule comprises;

retrieving the first abstraction component stored at the second computer and its associated second conditional statement, stored separately from the first rule;

determining a first result for the first conditional statement associated with the first rule to determine whether to allow access to the first document;

determining a second result for the second conditional statement associated with the first abstraction component to determine whether to allow access to the first document; and

determining a third result of the evaluated first rule based on the first result associated with the first conditional statement and the second result associated with the second conditional statement;

if the third result evaluates to a Boolean true, permitting the first user to access the first document; and

if the third results evaluates to a Boolean false, blocking the first user from accessing the first document.

2. The method of claim 1 wherein the organization comprises a first group and a second group, and the first user is within the first group.

3. The method of claim 1 wherein the organization comprises a first group and a second group, the first user is in the first group, and when the access comprises the first user attempting to send the first document to a user in the second group, approval to access the first document will not be given.

4. The method of claim 1 wherein the organization comprises a first group and a second group, and the first user is in the first group, and the method comprises:

when a second user of the second group attempts to access any information on a server in the first group, blocking access to the information.

5. The method of claim 4 wherein the server is an FTP server.

6. The method of claim 4 wherein the server is a Web server.

7. The method of claim 4 wherein the server is a file server.

8. The method of claim 1 wherein the organization comprises a first group and a second group, and the first user is in the first group, and the method comprises:

when an application program executing on a device of the second group attempts to access any information on a server in the first group, blocking access to the information.

9. The method of claim 1 wherein the organization comprises a first group and a second group, and the first user is in the first group, and the method comprises:

when an application program executing on a device of the second group attempts to access a server in the first group, blocking access to the server.

10. The method of claim 9 wherein the application program comprises at least one of instant messenger, file transfer protocol client application, or video conferencing client application.

11. The method of claim 1 wherein the organization comprises a first group and a second group, and the first user is in the first group, and the method comprises:

when an application program executing on a device of the second group attempts to access a device in the first group, blocking the access to the device in the first group.

12. The method of claim 1 wherein the organization comprises a first group and a second group, and the first user is in the first group, and the method comprises:

when an application program executing on a device of the second group attempts to access a document on a device in the first group, blocking the access to the document on the device of the first group.

13. The method of claim 1 wherein the organization comprises a first group and a second group, and the first user is in the first group, and the method comprises:

when an application program executing on a device of the second group attempts to access a device in the first group through a server, blocking the access to the server.

14. The method of claim 13 wherein the server is in the first group.

15. The method of claim 13 wherein the server is in the second group.

16. The method of claim 13 wherein the server is not in the first or second group.

17. The method of claim 1 wherein the organization comprises a first group and a second group, and the first user is in the first group, and the method comprises:

when an application program executing on a device of the second group attempts to access a device in the first group through a server, wherein the server is not in the first or second group, blocking the access to the device in the first group.

18. The method of claim 1 wherein the organization comprises a first group and a second group, the first user is in the first group, and approval is granted to the first user to access the first document, and the method comprises:

when a second user of the second group attempts to access the first document, approval of the access to the first document is denied.

19. The method of claim 1 wherein the first document is stored in an unencrypted form, and if the first user is permitted to access the first document, the method comprises encrypting the first document before permitting the first user to access the first document.

20. The method of claim 1 wherein the first document is stored in an encrypted form, and the if the third result evaluates to a Boolean true, permitting the first user to access the first document comprises not decrypting the first document.
