A Survey on Enhancement of Text Security Using Steganography and Cryptographic Techniques

Increase in the number of attack recorded during electronic exchange of information between the source and intended destination has indeed called for a more robust method for securing data transfer. Cryptography and steganography are well known and widely used techniques that manipulate information in order to cipher or hide their existence. Many different carrier file format scan be used but digital images are the most popular because of their frequency on the internet. The digital images are the most popular because of their frequency on the Web among all different carrier file formats. Image steganography, achieves the secrecy by embedding data into cover image and generating a stego-image. There are many types of steganography techniques each have their advantages and disadvantages. This paper discussed a technique used on the advanced LSB (least significant bit) and RSA algorithm. By matching data to an image, there is less chance of an attacker being able to use steganalysis to recover data. Before hiding the data in an image the application first encrypts it Priya Jain | Somesh Kumar | Raj Kumar Goel"A Survey on Enhancement of Text Security Using Steganography and Cryptographic Techniques" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-2 | Issue-5 , August 2018, URL: http://www.ijtsrd.com/papers/ijtsrd15800.pdf http://www.ijtsrd.com/computer-science/computer-security/15800/a-survey-on-enhancement-of-text-security-using--steganography-and-cryptographic-techniques/priya-jain
