Enhanced LSB Steganography with People Detection as Stego Key Generator

Technology used to hide secret message in a communication called Steganography. Secret message can be text, image or any file that can be converted into binary. This secret message inserted into cover file which can be in form of image, sound or video, basiccaly cover file must be bigger than the secret message in size. Many methods have been proposed on how to hide secret messages in a cover file. These method include spatial domain which work on bit instead of statistically on cover file. Least Significant Bit have been long known as the simplest steganography embedding method. In this research we proposed a method of LSB with enhanced technique to increase security. To extract secret message from cover file one should have particular stego key that describe the location of the message and how to reconstruct them. We utilize a people detection method as a stego key since most of video footage involving human figure, from personal video footage, movie video or security camera recording. While maintaining the appearance of the cover video from arousing suspiciousness, the size of secret message that can be embedded to be one point of consideration.
