Method for authenticating a forgery-proof object

A method for authenticating a forgery-proof object, wherein the object is marked with a code and additionally with a marking spaced apart from the code, characterized in that the method encompasses the following steps:

• determining a random position of the marking relative to a code position predetermined on the object;
• affixing the code and affixing the marking at the random position;
• storing position data of the random position in a database;
• joint detecting of the position of the marking affixed to the object and of the code position by a detection system and providing of image data or determination of the position data by the detection system and providing of the position data so determined;
• sending of the provided image data or the determined position data to the database by the detection system;
• determining of the position data from the image data by the database and comparing of the stored position data with the determined position data by a comparator communicating with the database, or
• comparing of the stored position data with the determined position data by a comparator communicating with the database and
• sending a confirmation of the authentication back to the detection system if the stored position data matches up with the determined position data or
• sending a rejection of the authentication back to the detection system if the stored position data does not match up with the determined position data;
• displaying the result of the authentication by the detection system.
