Secure serial numbers

New possibilities through cryptographic serial number generation

Serial numbers are the basis for traceability, product protection, and efficient processes. Therefore, choosing the right serial number should be carefully considered.

There are different methods for generating serial numbers. It should be noted that serial numbers must be suitable for many purposes in the course of digitization. These include the secure identification of a product, traceability, compliance requirements, and, last but not least, protection against counterfeiting in trademark protection.

Against this background, it is important that a number of criteria are met in order to reliably cover all areas of application.

Sequential numbers

This is the simplest method of generating serial numbers, as each new serial number is 1 higher than the previous one. This makes the method easy to implement, but also highly predictable. It therefore offers no protection against counterfeiting.

Random numbers

Here, the numbers are generated by a random generator, but the risk of duplication is very high. It requires a lot of resources and involves a great deal of work to avoid collisions and generate globally unique serial numbers.

Talking serial numbers

These are practical for internal evaluations, but due to their predetermined structure, they are easy to falsify and offer only limited flexibility.

UUID

These standardized 128-bit identifiers are unique worldwide, but not always URL-safe. URL security will play an increasingly important role, especially in the course of 2D migration in conjunction with the GS1-Digital Link.

Algorithmically generated numbers

Here, the serial numbers follow a predefined pattern or calculation logic. This method of serial number generation is flexible and can be expanded systematically. However, it offers a certain degree of predictability, which could potentially leave it vulnerable to counterfeiters.

Cryptographically generated serial numbers

Cryptographically generated serial numbers are among the most secure options, as these serial numbers are generated using cryptographic methods. This means that the serial numbers can be seamlessly integrated, are URL-safe, and cannot be predicted.

Conclusion:

  • A serial number is important for many different purposes. Therefore, the method of generation should be chosen carefully.

  • The use of cryptocodes generated from consecutive numbers provides maximum protection against counterfeiting. In addition, it reliably meets all requirements from a wide range of applications.

  • The use of cryptocodes also enables 2D migration and represents an important step toward digitalization.
