Example 1

In this example one, the first electronic device is device A, and the second electronic device is device B. The specific pairing process is as follows:

S401. Device A obtains text m through input method editing.

S402: Device A uses ultrasonic information 2 to encrypt text m and obtains encrypted text m’.

S403. Device A sends the encrypted text m’ to device B and sends ultrasonic information 1.

S404: Device B receives the encrypted text m’ and the ultrasonic information 1, and displays the encrypted text m’ on the screen of device B.

S405: Device B matches the previously locally recorded ultrasonic information 1 sent by device A with the currently received ultrasonic information 1 to obtain a matching result.

S406, if the matching result indicates that the match is successful, device B uses the ultrasonic information 2 to decrypt the encrypted text m', obtain the text m and display it on the screen of device B.

Here, text m can be displayed on the screen of device B in the form of a separate pop-up box.

S407, if the matching result indicates that the matching fails, the third prompt message for prompting the matching failure is displayed on the screen of device B, and the encrypted text m' is continued to be displayed.

For example, see Figure 5. After device A and device B perform ultrasonic pairing, device A sends a message "What are you doing today" to device B. After clicking Send, device A will send a message to device B based on the ultrasonic information sent by the currently paired device B. "What are you doing today" is encrypted and the ciphertext "897873TF8A" is obtained. At the same time, device A sends its own ultrasonic information; when device B receives the ciphertext "897873TF8A" sent by device A, it also verifies the ultrasonic wave sent by device A. Information, after verifying that the currently received ultrasonic information sent by device A matches the previously paired ultrasonic information, the ciphertext is decoded using the paired ultrasonic information, and the decoding result is displayed to the user.

For the second electronic device, the second electronic device also unpairs, that is, stops sending the first ultrasonic information, and deletes the previously recorded second ultrasonic information sent by the first electronic device. In this way, the energy consumption caused by the electronic equipment continuously sending ultrasonic information can be avoided, thereby saving energy consumption.
