Random pixel embedding for hiding secret text over video file

Data hiding can be done using steganography technique. The secret data is embedded in a carrier file such as video in such an invisible manner. Video format is chosen due to its capacity to store large data within frames. Moreover, because these frames are displayed rapidly, any tiny modification as a result of data hiding process is hardly observed by human eye. This study employed a Random Number Generator function into a method called Random Pixel Embedding. This was implemented by developing an application to hide text data in a video file as container. Quality testing for insertion phase result was done by measuring Signal to Noise Ratio which yielded a value of 99%. Meanwhile, testing for extraction phase result was done by measuring Character Error Rate which yielded value of 0.06. Those tests proved that this research produced a steganography application for hiding text message over video file which is ready to use.
