Abstract: A sonic signal encodes a symbol sequence representing a binary message, for delivery as audio content. The binary message into a sequence of symbols that are each associated with frequency characteristics transmitted over a time period. Two carriers are transmitted at two selected frequencies during each time period, delivering the binary data at a high rate. The symbol sequence is preceded by a prefix which takes the form of a sweeping frequency tone which sweeps over the frequency ranges of the carriers. Further, the amplitudes of the carriers are adjusted so that higher frequency transmissions are transmitted at higher sound pressure levels. Methods for synchronizing to the symbol sequence and decoding the symbol sequence are also described.

Abstract: An application based hardware identifier is generated for an application on a device. The application based hardware identifier is generated based on both information describing the application and information describing one or more hardware components of the device. The application based hardware identifier can also optionally be based on an identifier of a user of the device. The application based hardware identifier can be provided by the application to a service provider, allowing the service provider to associate the application based hardware identifier with a particular user or user account. However, as the application based hardware identifier is based on the application information, different applications on the same device will have different application based hardware identifiers. The application based hardware identifier thus helps maintain privacy by preventing tracking of the device across different applications.
