Abstract: The present application discloses example methods and systems. In one example method, sound wave information associated with a data transmission is monitored within a predetermined distance from the client device, where the sound wave information including predetermined security information. In response to detecting sound wave information associated with a data transmission, the sound wave information is parsed to obtain the predetermined security information included in the detected sound wave information. Pattern information is generated based on the predetermined security information and data information to be sent. The generated pattern information is then displayed so that a second device can obtain the generated pattern information.
