![5.1 Least significant bit algorithm Least significant bit (LSB) insertion is a common, simple approach to embedding information in a cover image [12]. The least significant bit in other words, the 8th bit of some or all of the bytes inside an image is changed to a bit of the secret message. When using a 24-bit image, a bit of each of the red, green and blue colour components can be used, since they are each represented by a byte. In other words, one can store 3 bits in each pixel. An 800 × 600 pixel image, can thus store a total amount of 1,440,000 bits or 180,000 bytes of embedded data [16]. For example a grid for 3 pixels of a 24-bit image can be as follows: (00101101 00011100 11011100) (10100110 11000100 00001100) (11010010 10101101 01100011)](profile/Jyoti-Waykule/publication/288630141/figure/fig2/AS:329622119043072@1455599445050/Least-significant-bit-algorithm-Least-significant-bit-LSB-insertion-is-a-common-simple.png)

Steganography is one of the most powerful techniques to conceal the existence of hidden secret data inside a cover object. Images are the most popular cover objects for Steganography and in this work image steganography is adopted. Embedding secret information inside images requires intensive computations and therefore designing Steganography in ha...

Steganography is the technique of concealing the covert data in natural and usual looking objects to keep the existence of the information secret. Cryptography is a study of protecting information against third parties. Steganography contributes cryptography in terms of the transmission of the secret data which is covered with ordinary objects. Hence, the secret data can be transmitted more secure since third parties can not even know of the presence of the data. This paper gives general information about steganography and examines steganography techniques that are performed on distinct cover media such as text, sound, image, and video.
