    摘要： The invention, as shown by the system in FIG. 2, relates to a client-side content tracking system of media files, e.g. digital music files. Audio tracking—or indeed multimedia tracking—is shifted to a client-side perspective, with the client tasked with establishing use of a selected source audio track by tracking—and then reporting uplink to the server—at least one of: entry and exit points associated with playing of at least one of said musical sections in the identified source audio track, and how the identified source audio track was used, performed or manipulated at the client device. Server functionality is designed, having regard to the reported tracking data and its link to a unique identifier to permit the media file (e.g. source audio track) to be selected and/or identified, to store or relay—possibly in the context of a subscription service and billing regime for content use—tracking data related to use of at least a portion of the source audio track at or by the client device. In the context of audio, reporting of use at a client device can, in turn, cause streaming of related multi-media content from a third-party database to the client device. For music, reporting of entry and end points into and out of sections of complete audio tracks can coincide with musically seamless audio transitions between sections.

    摘要： Methods are disclosed for an encoder to embed a data stream into a quantised PCM digital audio signal and for a corresponding decoder to both retrieve the data stream and losslessly reconstruct the exact original audio. Some methods employ complimentary amplification and attenuation, while others employ gain redistribution. Pre-emphasis and soft clipping techniques are described as methods of losslessly reducing the peak excursion of the PCM audio signal. Also described is the lossless placing of data at predetermined positions within an audio stream.

    摘要： Systems and methods are provided for using a hidden audio signal. In one exemplary embodiment, the method includes registering, at a central database, one or more of an identifier and a destination resource associated with the identifier, and encoding the one or more of the identifier and the destination resource in a hidden audio signal. The method further includes transmitting the hidden audio signal, including the one or more of the identifier and the destination resource, in connection with an acoustic signal, and receiving the acoustic signal at a user device. In addition, the method includes decoding the encoded one or more of the identifier and the destination resource at the user device; and requesting, from the central database, information associated with the one or more of the identifier and the destination resource. Further, the method includes receiving, at the user device, the requested information.

    摘要： A system and methods for permitting open access to data objects and for securing data within the data objects is disclosed. According to one embodiment of the present invention, a method for securing a data object is disclosed. According to one embodiment of the present invention, a method for securing a data object is disclosed. The method includes the steps of (1) providing a data object comprising digital data and file format information; (2) embedding independent data into a data object; and (3) scrambling the data object to degrade the data object to a predetermined signal quality level. The steps of embedding and scrambling may be performed until a predetermined condition is met. The method may also include the steps of descrambling the data object to upgrade the data object to a predetermined signal quality level, and decoding the embedded independent data.
