Abstract

A method and system for protecting software products from unauthorized use and distribution is described. The system comprises a client process executed on a client computer coupled to a producer computer over a network. The method comprises the steps of providing to a user a copy of the distributed software, the distributed software comprising an incomplete executable program requiring a security module to be installed prior to execution on the client computer. The user receives a registration code for use with the distributed software. Upon attempted execution of the distributed software the producer computer requests user registration from the user. Upon receipt of the registration information including the registration code from the user, the producer computer validates the registration code and constructing a security module for transmission to the client computer. The security module is integrated with the distributed software to allow execution of the executable program.

Claims

1. A computer-implemented method for protecting distributed software containing an executable program over a client server network, the method comprising:

providing to a user a copy of the distributed software, the distributed software comprising an incomplete executable program requiring a unique security module that includes at least a portion of a program instruction to be installed prior to execution on the client computer;

transmitting to the user a registration code for use with the distributed software;

requesting user registration from the user upon attempted execution of the distributed software;

receiving registration information including the registration code from the user;

validating the registration code received from the user;

constructing the unique security module upon validation of the registration code;

transmitting the unique security module to the client computer; and

accessing the portion of the program instruction of the unique security module with the distributed software to allow execution of the executable program.

2. The method of claim 1 wherein the distributed software comprises one or more executable programs embodied on disk media.

3. The method of claim 1 wherein the distributed software comprises one or more executable programs embodied in downloadable digital format.

4. The method of claim 1 wherein the user registration comprises a user name and password, and the method further comprises the step of defining a unique user profile for the user.

5. The method of claim 1 wherein the registration code is transmitted to the user through a method including mail, e-mail, fax, phone, or paper certificate accompanying the distributed software media.

6. The method of claim 5 wherein the registration code is a non-formulaic data string that is compared with a counterpart registration code stored on a server computer coupled to the client computer.

7. The method of claim 6 wherein the unique security module comprises a unique data string, and further comprising the step of encrypting the security module data string prior to installation and transmission to the client computer.

8. The method of claim 7 wherein the unique security module comprises a digital collection of arbitrary functions and dynamic link library pointers.

9. The method of claim 8 further comprising the step of verifying the unique security module and distributed software on a periodic time basis defined by the server computer.

18. The method of claim 1 wherein the unique security module comprises invalid computer instructions.

10. A client-server computer system for protecting distributed software containing an executable program distributed from a server computer to a client computer over the network, the system comprising:

means for providing to a user a copy of the distributed software, the distributed software comprising an incomplete executable program requiring a unique security module that includes at least a portion of a program instruction to be installed prior to execution on the client computer, wherein the incomplete executable program is stored on a computer-readable medium accessible to the client computer;

means for transmitting to the user a registration code for use with the distributed software;

means for requesting user registration from the user upon attempted execution of the distributed software;

means for receiving registration information including the registration code from the user;

means for validating the registration code received from the user;

means for constructing the unique security module upon validation of the registration code;

means for transmitting the unique security module to the client computer; and

means for accessing the portion of the program instruction of the unique security module with the distributed software to allow execution of the executable program.

11. The system of claim 10 wherein the distributed software comprises one or more executable programs embodied on disk media.

12. The system of claim 10 wherein the distributed software comprises one or more executable programs embodied in downloadable media.

13. The system of claim 10 wherein the user registration comprises a user name and password, and the method further comprises the step of defining a unique user profile for the user.

14. The system of claim 10 wherein the registration code is transmitted to the user through a method including mail, e-mail, fax, phone, or paper certificate accompanying the distributed software media.

15. The system of claim 14 wherein the registration code is a non-formulaic data string.

16. The system of claim 10 wherein the unique security module comprises a unique data string, and further comprising the step of encrypting the data string prior to installation and transmission to the client computer.

17. The system of claim 16 wherein the unique security module comprises a digital collection of arbitrary functions and dynamic link library pointers.

19. The method of claim 10 wherein the unique security module comprises invalid computer instructions.
