A method authenticates at least one of a media and data stored on said media in order to prevent at least one of piracy, unauthorized access and unauthorized copying of the data stored on said media. At least one predetermined error is introduced with the data resulting in mixed data. The mixed data is optionally stored on the media. The at least one predetermined error includes at least one authentication key or component thereof, for authenticating whether the media and/or data is authorized. The method includes the following sequential, non-sequential and/or sequence independent steps: reading the mixed data from the media, detecting the at least one predetermined error from the mixed data, and comparing the at least one predetermined error to the at least one authentication key or component thereof. The method also includes the steps of authenticating the media and/or the data in the mixed data responsive to the comparing, removing the at least one predetermined error from the mixed data resulting in substantially the data, and outputting the data as at least one of audio, video, audio data, video data and digital data substantially free of the at least one predetermined error.
A method for authenticating at least one of a media and data stored on said media in order to prevent at least one of piracy, unauthorized access and unauthorized copying of the data stored on said media, wherein predetermined errors are introduced with the data and storing the data on said media, the predetermined errors comprising at least one authentication key or component thereof, for authenticating whether the at least one of said media and data is authorized, said method comprising the steps of:
A method for authenticating at least one of a media and data stored on said media in order to prevent at least one of piracy, unauthorized access and unauthorized copying of the data stored on said media, wherein at least one predetermined error is introduced with the data into mixed data and storing the data on said media, the at least one predetermined error comprising at least one authentication key or component thereof, for authenticating whether the at least one of said media and data is authorized;
In a method for authenticating at least one of data stored to be stored on said media in order to prevent at least one of piracy, unauthorized access and unauthorized copying of the data, a computer data message at least one of stored, buffered and cached on a computer readable medium comprising at least one predetermined error introduced in the computer data message comprising the computer data message, the at least one predetermined error comprising at least one authentication key or component thereof, used in authenticating whether the computer data message is authorized, and wherein the predetermined errors are sufficiently minimal such that the at least one predetermined error is removed therefrom without substantially altering an audible component of the computer data message, and wherein the computer data message is transmitted substantially free of the at least one predetermined error preventing a destination processor from the at least one predetermined error comprising the at least one authentication key or component thereof, used in the authenticating whether the computer data message is authorized.
