In the global networked world, there is a phenomenal growth in data transfer and sharing.
Security plays a vital role in transmitting the private data over the communication medium
which tends to be open and insecure. Hence, in order to transfer the data securely to the
destination without any modifications, there are many approaches like cryptography and
steganography. This research deals with a combination of cryptography and
steganography techniques - Caesar Cipher and Least Significant Bit (LSB) Insertion
Technique. The formal is used to shuffle the secret message, while the letter is used to
embed the encoded message into the cover image. By so doing it can protect the message
from malicious attacks. The performance of the proposed method is evaluated by
standard measurements, PSNR and NCC values.
