Computer scripting engine to extract and execute steganographically hidden scripts in carrier scripts

摘要

A scripting engine causes a computer to perform operations. The scripting engine includes a first script interpreter that executes a carrier script. A steganographic decoder extracts a hidden script that is steganographically coded in the carrier script. A second script interpreter executes the hidden script. The carrier script may include a graphic image file and the hidden script may be steganographically coded in the graphic image file. The scripting engine may further include a decryption module that decrypts the hidden script with a key that may be steganographically coded in a third script.
