Abstract: A method, an apparatus and a system for implementing an external device simulating a keyboard relates to the field of electronic technology. The external device generates key-value data in a case that a user pressing a key is detected, and sends a start command to an Apple device after receiving a data request sent by the Apple device. After receiving the start command, the Apple device exits a soft keyboard and continuously sends the data request to the external device. After receiving the data request, the external device sends an attaching report command including the key-value data to the Apple device. The Apple device displays the key-value data and continuously sends the data request to the external device. After receiving the data request, the external device sends an end command to the Apple device. The Apple device pops up the soft keyboard again after receiving the end command.

Abstract: A method and system for safely entering a password, the method comprising: a smart key device receives a password verification request sent from an upper computer, generates and displays randomly arranged characters, and returns a password verification response to the upper computer; upon the reception of the password verification response, the upper computer displays a password input interface and waits for a user to input, upon the reception of a user input, obtains a password acquisition response according to the user input, and sends the password acquisition response to the smart key device; and the smart key device determines whether the user input is correct according to the received password acquisition response. By means of the present invention, a password input solution in which a user needs to click a different position every time a password character is entered is achieved. In addition, the numbers are not displayed on the screen of the upper computer, the security of the user's digital assets is further ensured.
