Abstract
The invention relates to a method and an authentication system for registering a random security feature (8) of a product (5) in a database (10) on the basis of a reproducible identification feature (6) of the product (5), wherein the security feature (8) is being linked to the identification feature (6), and said random security feature (8) is being registered on the condition that a preliminary authentication check (15) of the product (5) is positive, such that any subsequent definitive authentication checks of the product (5) may use the registered security feature.

A method for registering a random security feature of a product in a database on the basis of a reproducible identification feature of the product, wherein the random security feature is linked to the identification feature, comprising:
- performing a preliminary authentication check of the product, comprising:
- determining the identification feature of the product;
- searching the database for an entry comprising the identification feature;
- and
- determining that the preliminary authentication check is positive if the identification feature is found in the database;
- and
- registering the random security feature if the preliminary authentication check is positive;
- wherein any subsequent definitive authentication check of the product may use the registered random security feature.
An authentication system comprising:
- a database storing links between identification features and security features of products;
- and
- a mobile user reading device adapted to capture an identification feature and a random security feature on a product for authentication of the product;
- wherein:
- the mobile user reading device is adapted to perform and/or cause a preliminary authentication check of the product on the basis of the captured identification feature;
- during use, the database is searched for an entry comprising the identification feature and, if the database comprises an entry comprising the identification feature, the preliminary authentication check is positive;
- and
- if the preliminary authentication check is positive, the captured random security feature is registered in the database.
