Provided is a method for triggering a communication with a contact, the method obtaining sliding track data generated by actions on a contact button in the contact list. Then, identifying a direction of sliding track according to the sliding track data. When the direction of the slide track is determined, then triggering a corresponding operating instruction according to the direction of sliding track; wherein, when it is determined that the slide track is in a first direction the operating instruction is to call the contact's contact number and when the slide direction is in a second direction the operating instruction is a short message instruction for sending a short message to the contact's number.

An pry-proof encrypted keyboard. The encrypted keyboard comprises a keyboard panel (1), a lining board (2) assembled under the keyboard panel (1), a waterproof silicon rubber (4) and a main control panel (5). Convex rib circles (22) are provided on the circumference of the surface of the lining board (2) attached with the waterproof silicon rubber (4). The waterproof silicon rubber is extruded by the lining board (2) when the encrypted keyboard is assembled, and the thickness of corresponding waterproof silicon rubber (4) extruded by the convex rib circles (22) is less than 0.2 MM. The metallic lining board (2) can efficiently prevent fusion attack from the lateral face of the encrypted keyboard, meanwhile two convex rib circles (22) are added on the circumference of the surface of the lining board attached with the water silicon rubber (4), so that the thickness of the waterproof silicon rubber (4) at the grooves (41) is less than 0.2 MM, which is the diameter of the known thinnest needle, thus the attackers could not easily breakthrough the lining board (2) or the waterproof silicon rubber (4) to reach the inside of the encrypted keyboard, as a result illegally leading the wire out from the inside of the encrypted keyboard is efficiently prevented, thus the information of the keyboard is efficiently protected, and the security performance is improved.

Disclosed are a method, device and system for establishing conversation relation, which relates to the field of internet and. The method comprises the following steps: local terminal recognizes the opposite terminal within a preset range and establishes NFC connection with the opposite terminal, both of local terminal and opposite terminal have NFC module installed and instant messaging application running; when touching is detected, local terminal initiates a NFC request to opposite terminal via NFC connection, obtain opposite terminal user ID and certificate, and sends request information to the server; the server establishes conversation relation between local terminal and opposite terminal according to request information. With the present invention, local terminal obtains opposite terminal user ID and certificate by touching, and sends request information which includes local terminal user ID, opposite terminal user ID and certificate to the server, so that the server can establish sessions between local terminal and local terminal without certification of both sides, it avoids the trouble of locating, verifying, establishing friendship via network before session between friends within touch effectively

A dust-proof keyboard includes a keyboard main body and a plurality of keyboard keys (4) buckled on the keyboard main body. The keyboard keys (4) include key caps (41) and contact blocks (42) connected with one side of the key caps (41). The keyboard main body includes a silicone layer (3), a binding layer (5), a circuit board (7) and elastic sheets (8) corresponding to the keyboard keys (4). The elastic sheets (8) are located between the binding layer (5) and the circuit board (7), and the silicone layer (3) is located between the binding layer (5) and the keyboard keys (4). The silicone layer (3) is provided with a plurality of dust-proof rings (31) corresponding to the elastic sheets (8). The dust-proof rings (31) are hollow cylinders, at least one end of which is open, and the open ends are rightly placed opposite to the contact blocks (42). The dust-proof rings (31) do not influence a normal contact between the contact blocks (42) and the circuit board (7) while separating the working surfaces (D) of the contact blocks (42) from the environment, thereby playing a dust-proof and water-proof role, and enabling the operation of the keys of the dust-proof keyboard to be normal.
