English Abstract

This work aims at focusing or improving Least Significant Bit (LSB) method using measure the standard deviation, by answering the following questions: How to hide text in video based on the Least Significant Bit? And the sub question is: What are the steps to illustrate procedure of preparing video to hide text message in the LSB? The study suggests algorithm concealment improved transfer confidential letter to the formula of (Binary) , followed by the division of the image to hide data where clips blocks size (32 × 32) and account values standard deviation (Standard Deviation “SD”) for each section are then finding minimum and the maximum value of a standard deviation in addition to the average value, then isolate sections where the value of the standard deviation less than average value to be key concealment (i.e be adopted as locations to hide) and that by including all bits of the message into the (LSB) for each section of the selected sections, and the research used (Microsoft .Net C#).

The results proved the efficiency of the algorithm, where the hidden information did not cause any distortion on the video cover used.

The study suggested a future work in using an innovative way to compress the video output to return it to the original size without losing some of the data
