1. A method for identifying an object, comprising at least one object identifier, with an object code that is used to verify the authenticity of the object, comprising the steps:

  • a) generating of a unique random system code, which consists of a first and a second part of the system code, in which the first part of the system code is created from a first character set by a first random method and the second part of the system code from a second character set by a second random method, and storing the system code together with at least a first object-specific information in a first data memory, in which the first part of the system code is encrypted by a first encryption method and the second part of the system code by a second encryption method, which uses the first part of the system code as key, before storing them;

    b) generating of a random encryption key from a third character set by a third random method;

    of a unique assignment identifier by an assignment method and storing the encryption key, the assignment identifier and at least a second object-specific information in a second data memory;

    c) generating of an object code, which consists of at least the first part of the system code and the assignment identifier;

    encrypting of the system code by a third encryption method, which uses the encryption key as key;

    encrypting of the object identifier by a fourth encryption method which uses the system code as key; and

    storing the encrypted system code together with the encrypted object identifier in a third data memory;

    d) attaching the object code to the object;

    wherein the method provides a fourth data memory, in which query-specific data created during the verification of the authenticity of the object is stored.
