Abstract: A method for recognizing disguised malicious document, carried out by a computer system including a central processing unit (CPU), a memory, and a database storing rules for defining executable file and non-executable file, comprising steps of: receiving a static file through a network and an input/out interface; scanning the static file for a file header to determine if it is a non-executable file; analyzing file body of the non-executable file to locate components of an executable file and mark these positions; extracting components of the executable file from the non-executable file; concatenating the extracted components in accordance with a default rule or a heuristic rule to form a new file; and obtaining a new file that is executable, such that the received static file is a non-executable file having an embedded executable file, thus labeling the static file as a disguised malicious document.

Abstract: A method for recognizing malicious file has steps: receiving a static file through a network or an input/out interface to be stored in the memory; defining suspicious positions where components of a malware are possibly encrypted in the static file; decrypting the suspicious positions to identify a PE header and a shellcode; extracting the PE header and the shellcode terms in segments; and determining whether the PE header and the shellcode terms can be assembled into an executable binary which indicates a recognition of the malicious file.

Abstract: A sensing method for a capacitive touch panel includes charging a measure capacitor, setting the voltage across a mutual capacitor at the intersection of two traces of the capacitive touch panel, and then injecting partial charges of the measure capacitor into the mutual capacitor. When the intersection is touched, the capacitance value of the mutual capacitor is changed, and consequently the amount of charges injected into the mutual capacitor is changed. Hence, the voltage of the measure capacitor could be detected to determine whether or not the intersection is touched.
