Steganography is a practice of embedding confidential messages within another image, file or video while the sender and receiver communicates with each other. In present world, the safety of confidential information and privacy of communication has been a major issue. To resolve these issues of confidentiality and privacy in communication, researchers have been working to develop techniques to send data that are more secure without revealing it to anyone but the receiver. Over the past years, steganography is one of the technique that has been used to communicate securely between sender and receiver. The steganography method of LSB (Least Significant Bit) is the most utilized method for concealing the information in the bits of a picture. In this method, the data bit replaces the right most bit of an image changing the values of color components, like RGB(RED, GREEN, BLUE), of the image. This LSB method is vulnerable to stegnalysis, a new method is introduced of digital steganography by adding Hash function to LSB, it makes our data hiding method more secure. The HASH function is used to create pattern for concealing the message bits in the LSB of color components of each pixel of the selected picture. To make the steganography more secure, the RSA encryption is added to the steganography method, as it makes our data more secure.
