A Steganographic Analysis using Batch Steganography

Steganography is a scheme to conceal a secret file inside another means of information, also known as a cover, which can be retrieved at the destination. It is an approach that prevents unauthorized users from not only having access to important data but also prevents the attackers from knowing about the transmission of it. The fundamental target of this work is to introduce a robust steganographic method to send data to the destination without being noticed. Here, the secret message is compressed and encrypted using Lempel-Ziv-Welch [1] technique. Conventionally, a single image would be the cover image, but it has shortcomings. So, we implement Batch Steganography [2] with sequential hashing. It is the process of segregating the secret data and embedding it to multiple cover images using the Least Significant Bit method. The decoding and retrieving process is discussed as well.
