This present digital world is made up of both secure and insecure data communication. So, it is imperative to secure our data from adversaries. To protect our data while communications, lots of mechanisms are there, but still some vulnerability exists. Steganography is one of the security techniques where we can hide our data inside different mediums like video, image, and audio files. There are also some vulnerable exists. Since it hides the data in the least significant bit [LSB], attacks could be performed easily if the adversary knows some data concealed in the object. In this research, we proposed a new multi-layered security algorithm to reinforce security of steganography along with Cryptography to ensure the privacy and integrity of the data by using the native Operating System batch programming. In this Algorithm, we used several encryption techniques with many undercover keys, did ASCII to Binary conversions, exchange of symbols and Hash function. This Proposed mechanism reinforced the security of steganography by ensuring confidentiality and integrity. It would be a big challenge for the adversary. In this research, we used our coding to perform Steganography and to produce the hash code.
