Steganography is the technique of hiding a secret message or information in a cover message like an image, text or sound in such a way that only the desired or intended recipient knows about the existence of the secret data. It can be defined as the study of invisible communication which usually deals with the technique of hiding the existence of the secret message. The hidden message may be in the form of text, image, audio and video etc. An image after inserting the secret message into it by using a stego key is known as a stego image. Nowadays steganography is important due to an exponential growth in secret communication by potential computer users over the internet. In this paper we have analyzed the various steganography techniques and observed that the security of the secret message can be enhanced by random selection of the pixels for substitution in LSB steganography. Further the error metrics PSNR Peak Signal to Noise Ratio should be high and MSE Mean Square Error should be low indicating good quality re construction.

Nowadays steganography is important due to an exponential growth in secret communication by potential computer users over the internet. In this paper we have analyzed the various steganography techniques and propose to enhance the security of the secret message by random selection of the keys to extract the secret message and working towards increasing the PSNR Peak Signal to Noise Ratio and decreasing the MSE Mean Square Error .

Information hiding in a cover file is one of the most modernized and effective ways for transferring secret message from sender to receiver over the communication channel. There are many steganographic techniques for hiding secret message in image, text, audio, video and so on. Image Steganography is also one of the common methods used for hiding the information in the cover image. In this research work, the secret message is hidden in a cover image file using image steganography. LSB is very efficient algorithm used to embed the information in a cover file. The LSB based image steganography with various file sizes is analyzed and illustrated their results. Bitmap .bmp image is used as a cover image file to implement the proposed system. The detail Least Significant Bit LSB based image steganography is introduced. In this paper, the new embedding algorithm and extracting algorithm are presented. While embedding the secret message in a cover image file, the starting embedded pixel is chosen according to public shared key between sender and receiver. The original cover image and embedded image with secret message are analyzed with PSNR values and SNR values to achieve security. The resulting embedded image shows the acceptable PSNR and SNR values while comparing with the original cover image. The proposed system can help the information exchanging system over communication media.
Object oriented programming started with the development of these 2 programming language.
CLU
Smalltalk
These languages were not able to propel the OOP concepts till the advent of Java , followed by C++ and Python.
Abstract Data Type
The core of all Object Oriented programming is Abstract Data Type. The fundamental use of Abstract data type is that we can add user defined data type…
