Abstract
A technique and system protects documents at rest and in motion using declarative policies and encryption. Encryption in the system is provided transparently and can work in conjunction with policy enforcers installed at a system. A system can protect information or documents from: (i) insider theft; (ii) ensure confidentiality; and (iii) prevent data loss, while enabling collaboration both inside and outside of a company.
Claims20
A method comprising:
- providing a document management system managing a plurality of documents wherein the document management system comprises clients and servers;
- executing a first policy enforcer program installed on a first client;
- at the first client, intercepting by the interceptor code component of the first policy enforcer program a request by an application that is attempting to transfer a selected document, managed by the document management system, to a second client;
- after the interceptor code component intercepts the transfer request, not allowing the application to transfer the selected document to the second client, and using the policy engine code component of the first policy enforcer program, evaluating at least one policy associated with the selected document;
- as a result of the evaluating, determining that the transfer request is allowed, and encrypting the selected document;
- and
- allowing the application to transfer the encrypted document to the second client
- causing, in response to the allowed application transfer, a second policy enforcer installed on the second client to intercept a request for access to the encrypted document;
- causing the second policy enforcer to determine whether the request should be allowed;
- and
- after determining to allow access to the selected document, causing the second client to decrypt the encrypted document.

A method comprising:
- providing a document management system managing a plurality of documents wherein the document management system comprises clients and servers;
- at a first client, executing a first policy enforcer program;
- at the first client, trapping by the first policy enforcer program a request by an application that will transmit a selected document, managed by the document management system, to a second client;
- after the first policy enforcer program intercepts the transmission request, not allowing the application to transmit the selected document to the second client, and evaluating at least one policy associated with the selected document;
- as a result of the evaluating, determining that the transmission request is allowed, and encrypting the selected document;
- allowing the application to transmit the encrypted document to the second client;
- causing a second policy enforcer installed on the second client to intercept a request to access to the encrypted document
- sending a notification from a second policy enforcer regarding an attempt at the second client to open the encrypted document;
- determining the encrypted document is encrypted;
- and
- after determining the encrypted document is encrypted, causing the second client to decrypt the encrypted document to allow access to an unencrypted version of the selected document.
