tion security is a very useful term when it comes to the transmission of secret data or information between two objects or devices. Generally, cryptography is used for hiding information and sending messages in textual form. There are many techniques and algorithms that have come into the picture when it comes to hiding information. One of the most famous and widely used techniques is steganography. Steganography is basically a method used for hiding secret information or data which are in the form of texts, digital images, audio or voice representatives, and video files. LSB Steganography is one of the most simplest and efficient methods of Steganography. LSB ensures that there is no significant change in the input image and the stego-image, which makes it almost impossible for hackers to determine the difference between the original data and output data with a secret message. One of the frequently used encryption or cryptographic technique is Advanced Encryption Standard (AES). AES encryption is a method that converts plain text into cipher text. AES algorithm is much more efficient than the DES algorithm, which is why we will be making use of AES encryption. This method does not allow third party to access original information or to convert it in its original format.
