Abstract
The invention relates to an authorization verification method and devices suited therefor, which play back authorization data via a user interface (11) of an electronic playback device (1). During the playback of authorization data via the user interface (11) of a first playback device (1), the playback attributes are modified. The playback of authorization data via the user interface (11) of the first playback device (1) is compared with the playback of reference data via a user interface (21) of a second electronic playback device (2). Authorization is granted in the event the playback of authorization data via the user interface (11) of the first playback device (1) matches the playback of reference data via the user interface (21) of the second playback device (2), and modifications of the playback attributes are, in essence, time-synchronized. The dynamic modification of the playback attributes during the playback of authorization data and playback of the reference data render practically impossible the unauthorized copying of image contents or audio contents for falsifying an authorization. In addition, a simultaneous playback of authorization data and reference data render unnecessary inquiries made to an authorization center (3).

34. An authorization verification method, comprising:
-
reproduction of authorization data using a user interface of a first electronic reproduction device;
comparison of the reproduction of the authorization data using the user interface of the first reproduction device with the reproduction of reference data using a user interface of a second electronic reproduction device;
alteration of reproduction attributes during the reproduction of the authorization data using the user interface of the first reproduction device, so that the reproduction of the authorization data changes dynamically; and
granting of the authorization when there is a match between the reproduction of the authorization data using the user interface of the first reproduction device and the reproduction of the reference data using the user interface of the second reproduction device, where the match between the reproduction of the authorization data and the reproduction of the reference data is at least in the reproduction attributes, and alterations in the reproduction attributes are time-synchronized. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 64)

47. A system for authorization verification, comprising:
-
a first electronic reproduction device including a user interface for reproducing authorization data;
a second electronic reproduction device including a user interface for reproducing reference data;
means for reproducing the authorization data using the user interface of the first reproduction device and for altering reproduction attributes during the reproduction of the authorization data in time sync with the reproduction of the reference data using the user interface of the second reproduction device, and with alterations of reproduction attributes during the reproduction of the reference data, respectively, so that the reproduction of the authorization data changes dynamically. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 65, 66)

60. A computer program product comprising a computer-readable medium containing computer program code means for controlling one or more processors in a first electronic reproduction device that can be used in an authorization verification method such that,
the first reproduction device reproduces authorization data using a user interface of the first reproduction device and alters reproduction attributes during the reproduction of the authorization data, so that the reproduction of the authorization data changes dynamically, where the authorization data are reproduced and the reproduction attributes are altered during the reproduction of the authorization data in time sync with reproduction of reference data using a user interface of a second electronic reproduction device and with alterations of reproduction attributes during the reproduction of the reference data, respectively.
