After the reception unit 301 of third terminal receives the sound frequency sequence that first terminal sends, described sound frequency sequence just can be decoded by the decoding unit 302 of third terminal, it is thus achieved that connection restrictive condition, the end message of the second terminal and the identifying code hidden in described sound frequency sequence.

Here it should be noted that, in order to ensure the safety of transmission data, first terminal first can generate data ciphertext by connecting after restrictive condition, the end message of the second terminal and identifying code are encrypted, then the data ciphertext after encryption is changed into sound frequency sequence to be transmitted, so, described decoding unit 302, data ciphertext is obtained specifically for decoding described sound frequency sequence, described data ciphertext is decrypted, it is thus achieved that connect restrictive condition, the end message of the second terminal and identifying code.

Described detection unit 304, is used for detecting whether third terminal meets described connection restrictive condition.

The decoding unit 302 of third terminal decodes after connecting restrictive condition, the end message of the second terminal and identifying code, and the detection unit 304 of described third terminal can detect whether third terminal meets described connection restrictive condition.

Optionally, described connection restrictive condition can be the direction status information of described first terminal；So, described detection unit 304, whether the direction status information specifically for detecting third terminal is identical with the direction status information of described first terminal, if it is identical, then determine that described third terminal meets described connection restrictive condition, if it is different, then determine that described third terminal is unsatisfactory for described connection restrictive condition.

Example, when there being WIFI to cover, multiple terminals are (such as terminal A, terminal B and terminal C) need to access same router (i.e. the second terminal), now first terminal such as terminal A has learned that identifying code is connected to router, as shown in Figure 4, the user of terminal A clicks " sharing password to friend ", terminal A can by the direction status information of terminal A, route-map and identifying code are converted into sound frequency sequence, then described sound frequency sequence is sent, so, terminal B or terminal C just can receive the sound frequency sequence that first terminal sends.
