Abstract
Method for producing a security device (1) comprising the following steps: providing at least one stochastic selector (8), generating a coupling between an identifier (11) and one particular combination of security features (6) from a finite set (5) of distinct combinations of security features based on the at least one stochastic selector (8), registering the coupling in a database (12); and applying an identification element (3) comprising the identifier (11) and a non-printable security element (2) comprising the particular combination of security features (6) according to the coupling to a substrate (22) to produce a security device (1).
Claims14
A method for registering an additional random security feature of a security device to an identifier of the security device in a database, comprising:
- providing a security device produced according to the following:
- providing at least one stochastic selector;
- generating a coupling between an identifier and one particular combination of security features from a finite set of distinct combinations of security features based on the at least one stochastic selector;
- registering the coupling in a database;
- and
- applying an identification element including the identifier and a non-printable security element including the particular combination of security features according to the coupling to a substrate to produce a security device;
- performing a preliminary authentication check of the security device according to the following:
- determining an identifier of the security device;
- determining a particular combination of security features present on the security device and selected from a finite set of distinct combinations of security features;
- determining that the preliminary authentication check is positive if a coupling between the determined identifier and the determined particular combination of security features is registered in the database;
- and
- registering the additional random security feature if the preliminary authentication check is positive;
- wherein any subsequent definitive authentication check of the security device may use the registered additional random security feature.
An authentication system comprising:
- a database storing couplings between identifiers and additional random security features of security devices;
- and
- a mobile user reading device adapted to capture an identification element, a non-printable security element and an additional random security feature of a security device for authentication of the security device;
- wherein:
- the mobile user reading device is adapted to initiate a preliminary authentication check of the security device on the basis of a captured identification element and a captured non-printable security element;
- wherein the captured identification element includes an identifier;
- and
- wherein the captured non-printable security element includes a particular combination of security features from a finite set of distinct combinations of security features;
- during use, the database is searched for an entry including a coupling between the identifier and the particular combination of security features and, if a matching entry is found, the preliminary authentication check is positive;
- and
- if the preliminary authentication check is positive, the captured additional random security feature is registered in the database.
