Abstract
A method for producing a security device includes 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.
Claims15
A method for producing a security device comprising 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.
A set of security devices, each security device comprising:
- at least one identification element;
- and
- at least one non-printable security element;
- wherein the at least one identification element includes an identifier;
- wherein the at least one non-printable security element exhibits one particular combination of security features from a finite set of distinct combinations of security features;
- wherein a coupling represented by the security device between the identifier of the at least one identification element and the particular combination of security features of the at least one non-printable security element is stochastic.
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.
