Abstract

The invention provides a key-defending recording method and a key-defending recording system which are applied to a computer with a keyboard. The method comprises the following steps of: when input information of keys of a keyboard is detected, intercepting the input information; encrypting the input information by adopting an asymmetric cryptographic algorithm; sending the encrypted input information to a keyboard buffer area of a computer memory; calling the encrypted input information in the keyboard buffer area, monitoring and analyzing the keyboard buffer area to judge whether the calling is legal or not; and when the calling is judged to be legal, decrypting the called input information, and when the calling is judged to be abnormal, refusing to send a decryption request. Therefore, by the method and the system, the aim of protecting keyboard input is fulfilled, so that the safety of the keyboard input for users can be ensured to a large extent.
