Abstract

A method and a system for depositing digital works and a corresponding computer program and a corresponding computer-readable storage medium are disclosed, which can be used for depositing digital works under the auspices of an attorney or notary via an encrypted communication link in the Internet. According to the disclosed method, a checksum of the digital work is generated and/or the digital work is provided with a timestamp, optionally by a service provider for a fee. The checksum and/or the digital work signed with a timestamp is registered in an identification document and the identification document is certified and deposited. Preferably, the identification document is certified by a notary, by an attorney or by an institution.

Claims

1. A method for depositing a digital works, comprising the steps of:

generating a checksum of the digital work and/or providing the digital work with a timestamp,

registering the checksum and/or the digital work signed with a timestamp in an identification document and

certifying and depositing the identification document.

2. The method according to claim 1, wherein the identification document is certified by a notary, by an attorney or by an institution.

3. The method according to claim 1, wherein the identification document is deposited with/by a notary, an attorney or an institution.

4. The method according to claim 1, wherein the digital work is stored on a computer-readable storage medium.

5. The method according to claim 1, wherein the checksum is generated automatically.

6. The method according to claim 1, wherein that the checksum comprises a unique, reproducible, irreversible, electronic fingerprint.

7. The method according to claim 1, wherein the checksum comprises a hash value.

8. The method according to claim 7, wherein the hash value is generated by a combination of a hash value methods.

9. The method according to claim 4, wherein the digital work stored on a computer-readable storage medium and the identification document are certified and deposited together.

10. The method according to claim 1, further comprising the step of providing on a client-computer a program module for transmitting the digital work to a remote data processing system for communication between the client-computer and the remote data processing system.

11. The method according to claim 10, wherein the program module is started by a browser on the client-computer or is realized as a desktop application.

12. The method according to claim 10, wherein the digital work is transmitted to the data processing system in several upload blocks, where the number of required upload blocks is determined before the digital work is transmitted to the data processing system.

13. The method according to claim 9, wherein a timestamp is used for certifying the digital work.

14. The Method according to claim 13, further comprising the steps of

providing a pair of keys comprising a private and a public key for certification,

checking timeliness of the private key by an applet installed in the browser of a client, and

signing the digital work depending on the check.

15. The method according to claim 1, further comprising the steps of

creating a digital work within a closed network,

thereafter transmitting the digital work to a first data processing system situated within the closed network,

transmitting the digital work only from this first data processing system to a second data processing system outside the closed network, and

certifying the digital works at the second data processing system.

16. A system for performing a method for depositing a digital work, comprising at least

means for reading the digital work into a data processing system,

means for generating a checksum for the digital work,

means for outputting the checksum for depositing the checksum.

17. The system according to claim 16, wherein the system is connected with the Internet or with a closed network by means for data transmission.

18. A system for performing a method for depositing a digital work, comprising at least

means for reading the digital work into a data processing system,

means for automatically generating a pair of a public and a private key,

means for automatically signing the digital work using the private key,

means for outputting the public key for depositing the public key.

19. The system according to claim 18, wherein the system is connected with the Internet or with a closed network by means for data transmission.

20. A computer-readable storage medium, on which a program is stored which enables a data processing system, after the computer program has been loaded in the memory of the data processing system, to execute a method for depositing a digital work, wherein

a checksum of the digital work is generated and/or the digital work is provided with a timestamp,

the checksum and/or the digital work signed with a timestamp is registered in an identification document, and

the identification document is certified and deposited.

21. A process for depositing digital works, comprising the steps of:

offering generation of a checksum of digital works and/or signing of the digital work with

a timestamp through a service provider for a fee,

registering the generated checksum and/or the digital work signed with a timestamp in an identification document, and

certifying and depositing the identification document.

22. The process according to claim 21, further comprising the step of providing a person authorized to make the deposit with a device for generating a checksum of digital works, said device provided by a service provider for a fee.

23. The process according to claim 22, wherein the device is a certified device.
