Abstract

The invention discloses a method, device and terminal based on ultrasonic communication. The method based on ultrasonic communication can decode and encode ultrasonic carrier information of any code system, so that a user of a mobile terminal can more conveniently enjoy services provided by the ultrasonic carrier information without being restricted by a visual environment. The message content sent to a background server by the mobile terminal can be encrypted, and the message content received by the background server can be decrypted. The encryption and decryption of the information can ensure the security of the data, and the method is suitable for services with high data security, such as payment service, voting service and the like. The mobile terminal and the background server cooperatively work to jointly complete service provision. The mobile terminal not only sends a service providing request message to the background server, but also can perform partial work of providing the service, so that the load of the server is reduced, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and terminal based on ultrasonic communication. Background technique [0002] At present, the two-dimensional code or bar code uses a certain specific geometric figure, and the black and white figure distributed in the two-dimensional direction according to a certain rule to record the data symbol information. Mobile phone QR code is the application of QR code technology on mobile terminals. Mobile phone QR code services are currently divided into two categories: mobile phone read applications and mobile phone main reading applications. [0003] Mobile phone reading applications usually allow users to read image information through special equipment, and then complete the service through various online or offline methods, and the electronic certificate is then transmitted and fed back on the screen of the mobile terminal through the mobile network....
