US 2010/0059588 A1 · AUTHORIZATION VERIFICATION METHOD AND DEVICES SUITED THEREFOR

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).

Claims31

Dependent claims

An authorization checking method, comprising:

transmitting authorization data from an authorization center via a telecommunication network to a first reproduction device;
transmitting reference data from a reproduction control center via the telecommunication network to a second reproduction device;
transmitting reproduction control data from the reproduction control center via the telecommunication network to the first reproduction device;
altering reproduction attributes during reproduction of the authorization data using a user interface of the first reproduction device, such that reproduction of the authorization data changes dynamically, alteration of the reproduction attributes during reproduction of the authorization data taking place based on the reproduction control data from the reproduction control center;
and
granting authorization if 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 a user interface of the second reproduction device, the match between the reproduction of the authorization data and the reproduction of the reference data consisting at least in the reproduction attributes, and alterations in the reproduction attributes being time-synchronized.

3 more elements

A system for authorization checking, comprising:

a computer-based authorization center for transmitting authorization data via el telecommunication network to a first reproduction device;
a computer-based reproduction control center for transmitting reproduction control data via the telecommunication network to the first reproduction device and for transmitting reference data via the telecommunication network to a second reproduction device;
and
means for reproducing the authorization data using a user interface of the first reproduction device and for altering reproduction attributes an the basis of the reproduction control data during reproduction of the authorization data in time synchronized manner respectively with reproduction of the reference data using the user interface of the second reproduction device and with alterations to reproduction attributes during reproduction of the reference data, such that reproduction of the authorization data changes dynamically.

1 more element

A tangible computer readable medium containing a computer program that when executed by a computer causes the computer to control one or more processors in a first electronic reproduction device which is configured for use in an authorization checking method, in such a way that the first reproduction device receives authorization data via a telecommunication network from a computer-based authorization center, that the first reproduction device receives reproduction control data via the telecommunication network from a computer-based reproduction control center, that the first reproduction device reproduces authorization data using a user interface of the first reproduction device and alters reproduction attributes based on the reproduction control data during reproduction of the authorization data, such that reproduction of the authorization data changes dynamically, the authorization data being reproduced and the reproduction attributes being altered during reproduction of the authorization data in time synchronized manner respectively with reproduction of reference data using a user interface of a second electronic reproduction device and with alterations of reproduction attributes during reproduction of the reference data.
