Abstract

An improved method and system for digital rights management is described.

Claims

1. A method for sending an electronic document and/or message from a sender to a recipient, and encrypting the document and/or message, the method comprising:

selecting a document to encrypt and send to the recipient;

selecting a set of recipient rights for the document;

encrypting the document;

sending the encrypted document from the sender to the recipient;

receiving the encrypted document at a terminal of the recipient; and

accessing the document according to the set of recipient rights.

2. The method of claim 1 wherein the set of rights include at least one from the following set:

reading rights indefinitely;

reading rights up to a preset date;

printing rights indefinitely;

printing rights up to a preset date;

copying rights indefinitely; and

copying rights up to a preset date.

3. The method of claim 1 wherein the encrypting the document includes utilizing the terminal of the recipient to establish a computer passport.

4. The method of claim 3 further including utilizing at least one of the following:

the terminal'"'"'s MAC address, master serial number, Basic Input/Output System (BIOS) information or BIOS date.

5. The method of claim 1 further including using a certificate of the sender.

6. The method of claim 1 further including selecting from a set of certificates of the sender.

7. The method of claim 1 further including selecting a document to wipe out completely from any storage device.

8. A system for sending an electronic document and/or message from a sender to a recipient, and encrypting the document and/or message, the system comprising:

a sender'"'"'s email system that selects a document to encrypt and send to the recipient, wherein the sender'"'"'s email system provides selection of a set of recipient rights for the document, encryption of the selected document and the ability to send the encrypted document from the sender to the recipient;

a receiver'"'"'s email system that receives the encrypted document at a terminal of the recipient; and

a viewer that accesses the document according to the set of recipient rights.

9. The system of claim 8 wherein the set of rights include at least one from the following set:

reading rights indefinitely;

reading rights up to a preset date;

printing rights indefinitely;

printing rights up to a preset date;

copying rights indefinitely; and

copying rights up to a preset date.

10. The system of claim 8 wherein the encryption of the document includes utilizing the terminal of the recipient to establish a computer passport.

11. The system of claim 10 further including utilizing at least one of the following:

the terminal'"'"'s MAC address, master serial number, Basic Input/Output System (BIOS) information or BIOS date.

12. The system of claim 8 further including using a certificate of the sender.

13. The system of claim 8 wherein the sender'"'"'s email system includes selection from a set of certificates of the sender.

14. The system of claim 8 wherein the sender'"'"'s email system includes selection of a document to wipe out completely from any storage device.

15. A method for sending an electronic document and/or message from a sender to a recipient, and encrypting the document and/or message, the method comprising:

selecting a document to encrypt and send to the recipient;

selecting a set of recipient rights for the document, wherein the set of recipient rights includes at least from the following set;

reading rights indefinitely;

reading rights up to a preset date;

printing rights indefinitely;

printing rights up to a preset date;

copying rights indefinitely; and

copying rights up to a preset date;

encrypting the document;

sending the encrypted document from the sender to the recipient;

receiving the encrypted document at a terminal of the recipient; and

accessing the document according to the set of recipient rights.

16. The method of claim 15 wherein the encrypting the document includes utilizing the terminal of the recipient to establish a computer passport.

17. The method of claim 16 further including utilizing at least one of the following:

the terminal'"'"'s MAC address, master serial number, Basic Input/Output System (BIOS) information or BIOS date.

18. The method of claim 15 further including using a certificate of the sender.

19. The method of claim 15 further including selecting from a set of certificates of the sender.

20. The method of claim 15 further including selecting a document to wipe out completely from any storage device.
