KEYBOARD SECURITY METHOD PREVENTING APPLICATION HOOKING

摘要

A keyboard security method preventing application program hooking is provided to cut off application program hooking fundamentally by outputting inputted characters into a virtual window produced at the same location of a real window, thereby protecting the input information even at application program level. Composition information of a web page is created and stored(S10). Focus movement into an input window of a web browser is sensed(S20). A security driver is registered in an interrupt descriptor table(S30). Keyboard input information is transmitted from the security driver(S40). The received keyboard input information is converted into character data, and then stored in a buffer(S50). A virtual window is created(S60). The converted character data is outputted into the virtual window(S70). The virtual window is removed, and the input characters are transmitted to a PKI(Public Key Infrastructure)(S80).
