Object e.g. person, identifying/authenticating method, involves extracting characteristic feature, and comparing feature with object's characteristic feature that is stored in data base and detected at specific time point

摘要

The method involves positioning an object and a detection unit together, and optically detecting a marking or a part of the marking of an enlarged print image (6-1). Digital image data are produced, where the data comprise a marking or a part of marking in a machine processed form. A characteristic feature within the image data is localized, and is extracted. The characteristic feature is compared with a characteristic feature of the object, which is detected at a specific time point and is stored in a data base, and correlation probability of the characteristic features is determined. An independent claim is also included for a device for identifying and/or authenticating an object based on a production-related and/or processing-related feature.
