Abstract
A method for serialization of items, comprising encrypting a serial number of each item using an encryption key k to obtain unique serial numbers and marking the unique serial numbers on the items. The unique serial numbers having a length L are included into a string of symbols having a length L′, with L′ larger than L, and marked on the items. A corresponding method for recovering a unique code and corresponding serial number from a string of symbols marked on an item, as well as corresponding serialization and recovering systems are disclosed.
Claims17
A method for serialization of items, comprising:
- encrypting a unique serial number of each item using encryption key k to obtain a corresponding unique code, and
- marking each item with its corresponding unique code,
- wherein each unique code has a length L and is included into a string of symbols having a length L′ that is marked on the corresponding item, wherein L′ is larger than L, and wherein the string of symbols further includes at least a part of a unique code obtained from encrypting a preceding unique serial number and/or at least a part of a unique code obtained from encrypting a next unique serial number, wherein in the string of symbols the unique code corresponding to the item is concatenated ahead with the end of the unique code obtained from encrypting the preceding unique serial number and/or concatenated after with the beginning of the unique code obtained from encrypting the next unique serial number.
A system for serialization of items, comprising:
- a memory and a processor, the memory together with the processor are configured to cause the system to encrypt a serial number of each item using an encryption key k stored in the memory to obtain corresponding unique codes, and
- a marking device connected to the processor and adapted to mark the unique codes received from the processor on the items,
- wherein the system is configured to include each unique code having a length L into a string of symbols having a length L′, wherein L′ is larger than L, and wherein the string of symbols further includes at least a part of a unique code obtained from encrypting a preceding unique serial number and/or at least a part of a unique code obtained from encrypting a next unique serial number, and mark the string of symbols on a corresponding item, wherein in the string of symbols the unique code corresponding to the item is concatenated ahead with the end of the unique code obtained from encrypting the preceding unique serial number and/or concatenated after with the beginning of the unique code obtained from encrypting the next unique serial number.
