Abstract

In order to provide a method wherein, by using a storage medium arranged on goods, it is possible to distinctly register a conveyance of ownership or title on this storage medium, and wherein only the current owner or proprietor and possibly also an independent verifying agency has access to the storage medium, the following method is proposed:

A method for documentation of an ownership or title of goods and also the conveyance of same, wherein the goods are provided with an overwritable electronic storage medium and on the storage medium is deposited a first digital key (Public Key) of an individual pair of keys, consisting of the first digital key and a second digital key (Private Key) of a first owner or proprietor of the goods, while the first proprietor has possibly limited read and write access to the storage by using the second key, and upon conveyance of the ownership or title of the goods from the first owner or proprietor to a second owner or proprietor either
a) the latter hands over to the first owner or proprietor a first digital key (Public Key) of his individual pair of keys, consisting of the first digital key (Public Key) and a second digital key (Private Key), and the first owner or proprietor to complete the transfer of title or ownership of the goods makes use of his second digital key to overwrite his first digital key saved on the storage medium with the first digital key of the second of the second owner or proprietor, so that the second owner or proprietor obtains possibly limited read and write access to the storage by using the second digital key of his individual pair of keys, or
b) the first owner or proprietor makes use of his second digital key to overwrite his first digital key on the storage medium with a separate first digital key (Private Key) and thus deactivates the storage medium for a further reading or writing by the second owner or proprietor.

Claims

1-7. -7. (canceled)

8. A method for documentation of an ownership or title of a good and also the conveyance of same comprising:

providing the good with an overwritable electronic storage medium accessible by a first pair of digital keys, wherein the first pair of digital keys includes a first digital key stored on the storage medium and a second digital key enabling a first owner or proprietor read and write access to the storage medium; and

enabling the storage medium to document a change of ownership or title of the good from the first owner or proprietor to a second owner or proprietor by the second owner or proprietor providing the first owner or proprietor a first digital key of a second pair of digital keys, and the first owner or proprietor completes the transfer of title or ownership of the good by using the first owner or proprietor'"'"'s second digital key to overwrite the first owner or proprietor'"'"'s first digital key saved on the storage medium with the first digital key of the second pair of digital keys to enable the second owner or proprietor to further change ownership or title to a subsequent owner by obtaining read and write access to the storage by using a second digital key of the second pair of digital keys.

9. A method according to claim 8, wherein each of the first digital keys of each pair of keys is a public encryption key and the second digital keys of each pair of keys is a private encryption key.

10. A method according to claim 8, wherein goods-related data selected from the group consisting of commercial documentation data, freight documentation data and combinations thereof is saved on the storage medium.

11. A method according to claim 8, wherein goods-related data selected from the group consisting of type of goods, article number, place of manufacture, time of manufacture, shelf life and combinations thereof is saved on the storage medium.

12. A method according to claim 8, wherein data about the possessors or owners and their sequence in time is saved on the storage medium.

13. A method according to claim 8, further comprising enabling a verification agency at least read access to the storage medium by maintaining on the storage medium an additional first digital key of an additional pair of digital keys that enables at least read access by using an additional second digital key of the additional pair of keys.

14. A method according to claim 8, wherein a radio-frequency storage tag is used as the storage medium.

15. A method according to claim 8, further comprising enabling locking of the storage medium to further reading and writing by an owner or proprietor of the good using a second digital key from a pair of keys to overwrite the owner or proprietor'"'"'s first digital key on the storage medium with a locking digital key that locks and prevents the storage medium from permitting further reading or writing by the owner or proprietor.

20. A storage medium configured to implement the method of claim 8.

21. A storage medium configured to implement the method of claim 15.

16. A method according to claim 16, wherein the locking digital key is the first digital key of an individual pair of keys of a third party that includes a second digital key permitting the third party to unlock and reactivate the storage medium.

17. A method according to claim 16, wherein data about the possessors or owners and their sequence in time is saved on the storage medium.

18. A method according to claim 16, wherein goods-related data selected from the group consisting of commercial documentation data, freight documentation data and combinations thereof is saved on the storage medium.

19. A method according to claim 16, wherein a radio-frequency storage tag is used as the storage medium.

22. A storage medium configured to implement the method of claim 16.

23. A method for documentation of an ownership or title of a good and also the conveyance of same comprising:

providing the good with an overwritable electronic storage medium including a first digital key of an individual pair of keys, wherein the pair of keys includes the first digital key and a second digital key of an owner or proprietor of the good, and wherein the owner or proprietor has read and write access to the storage medium by using the second key; and

changing ownership or title to the good using the second digital key by overwriting the first digital key on the storage medium with a separate locking digital key that locks and prevents the storage medium from further reading or writing by the owner or proprietor.

24. A method according to claim 23, wherein the separate locking digital key is a public locking digital key of a third party'"'"'s pair of keys that includes a second digital private unlocking key permitting the third party to unlock and have at least read access to the storage medium.

25. A method according to claim 24, wherein the third party is selected from the group consisting of the manufacturer of the good, an independent institution and a verification agency.

26. A method according to claim 25, wherein goods-related data selected from the group consisting of type of goods, article number, place of manufacture, time of manufacture, shelf life and combinations thereof is saved on the storage medium.

27. A method according to claim 23, wherein goods-related data selected from the group consisting of type of goods, article number, place of manufacture, time of manufacture, shelf life and combinations thereof is saved on the storage medium.

28. A method according to claim 27, wherein a radio-frequency storage tag is used as the storage medium.

29. A storage medium configured to implement the method of claim 24.
