Abstract: A method for triggering a security-relevant function of a system by a terminal including generating or selecting an input pattern by the system; inputting a request to carry out the function by the terminal; transmitting the input pattern to the terminal; displaying the input pattern on a display and user interface of the terminal, which pattern must be input by a user; capturing and storing an input by a user on the display and user interface by the terminal; transmitting the captured and stored input from the terminal to the system; receiving the captured and stored input by the system; comparing the received input with the transmitted input pattern in the system; and carrying out the function by the system in response to the received input matching the input pattern within a predefined extent. Also disclosed is an associated system.

Abstract: A method and apparatus for a motor vehicle to increase safety for remote triggering and a motor vehicle having such an apparatus. Data are received from a second device, from which there is a communication link to a first device. The data are associated with user inputs in an application on the second device. The first device receives, for each user input, a portion of the data in a data packet of a data packet structure and prevents remote triggering if the data packet structure does not correspond to a predetermined data packet structure. A difference in the reception sequence of the data packets from the predetermined order is an indicator of malfunctioning in the second device. Preventing remote triggering in the event of a difference reduces the risk of remote triggering by a faulty second device and faulty remote triggering.
