The peep-proof input keyboard comprises a circuit board, a keyboard, and a peep-proof cover, the keyboard includes a plurality of keys configured to input information, a portion of the circuit board corresponding to the keys is provided with a first connecting finger configured for the pressing operations of the keys, the circuit board is provided with a second connecting finger configured to control the keyboard to work and be turned off, and a bottom of the peep-proof cover is provided with at least one support post configured to abut against the second connecting finger so as to enable the keyboard to work. By providing the circuit board with the second connecting finger, whether the keyboard can work or not is controlled by connection and disconnection of the second connecting finger; and by providing the peep-proof cover with the support post, the second connecting finger is connected by the support post, such that the keyboard can perform the input work. When the peep-proof cover falls off, the keyboard is in a shut-down state, that is, the keyboard cannot perform the input operation, so that the information input by users is prevented from being peeped.
