Data processing method and system

The application relates to a data processing method and system. The method comprises the following steps: acquiring network data and sound waves synthesized with the network data through a terminal, wherein the sound waves are converted from resource data by encoding; and calling an audio playing device of the terminal according to operation performed on the network data on the terminal by a user, and playing the sound waves synthesized with the network data to one or more surrounding users. According to the method and the system disclosed by the application, the resource data is converted into the sound waves which are synthesized into the network data easily and conveniently through a large amount of existing network data in order to trigger sound wave transmission resources through the network data, so that resource receiving and transmitting parties do not need special equipment or App; the resource transmission way is simplified; the data sharing propagation/transmission efficiency is increased; data sharing becomes easy and convenient; the data transmission speed and efficiency are increased; and the data propagation range is expanded. Moreover, the sound waves are kept in an inaudible wave frequency band, and propagation data can be shared without any interference.
