Authentication method for authentication of persons upon usage of services, involves generating authentication code and information is provided about authentication code to user
The authentication method involves generating an authentication code and information is provided about the authentication code to a user. Another information that makes the terminal device suitable for outputting various tones or colors in a time sequence through a loudspeaker or a color display, respectively, is prepared from the former information. An analysis unit connected to sensors (102,102') has access to the authentication code and decodes the time sequence of the various tones or colors and compares the result of the decoding to the authentication code. Independent claims are included for the following: (1) an arrangement for the execution of the authentication method; (2) a computer program; (3) a computer-readable storage medium on which a program is stored; and (4) a method for downloading a computer program from an electronic data network.
