Abstract: This invention relates to a method for the determination of an authorization, using at least one biometrical feature, said biometrical feature being collected by means of a sensor unit and being compared with individual-related stored data sets for this feature and leading to a result of the comparison which allows a decision on the presence of the authorization, wherein at a positive decision on the presence of the authorization the data of the collected biometrical feature are stored in an individual-related fashion as a further data set.

Abstract: The invention relates to a lock, in particular a mortise lock for a door. Said lock comprises a locking cylinder that can in particular be inserted into a door leaf and a shaft consisting of two sections, each section of said shaft having a handle at the end, preferably a rotary knob or a standard door handle and being actively interconnected by means of a coupling after recognition of an authorisation code. The aim of the invention is to develop a lock of this type in such a way that it can used for various applications as a result of its construction design, in particular with a standard locking cylinder in various doors and that it allows, in particular, a simple, reliable, low-energy actuation of the locking mechanism. To achieve this, the coupling (11) comprises at least two, preferably four or more rolling members (17) that are guided in recesses (18) of a second part (10) of a first section (5) of the shaft (3).
