<p>A system and method for sharing digital information between two or more devices in close proximity using a sound signal. The sending device obtains a globally unique share identifier from an information sharing system. The sending device then uploads the digital information to be shared to the information sharing system and transmits the sharing identifier to a receiving device via sound signals. The receiving device communicates the sharing identifier to the information sharing system and receives the digital information from the information sharing system. The information transferred from the sharing system can be password encrypted, the information transfer can be limited to a specified time period or the information transfer can be limited to receiving devices located within a specified geographic extent. In some embodiments of the invention, the sending device broadcasts a sound signal with a sharing identifier encoded in the sound stream and a plurality of receiving devices access digital information at the information sharing system using the sharing identifier as recovered from the sound stream.</p> |
