Dsuraksha: Cryptography and Steganography Technique-Enabled Integrated System for Data Protection in Multimedia

Cybersecurity is a primary concern nowadays in the 21<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">st</sup> century. Technology is growing enormously faster with the challenges of securing crucial data from intruders. We must accumulate cryptographic and steganography mechanisms to save our data from malicious activities. Cryptography and steganography play a vital role in improving the security of sensitive data in text and images. Traditional cryptographic techniques for securing multimedia data include Data Encryption Standard (DES), Advanced Data Standard (AES), Blowfish, Block-cipher, RSA, Diffee-Hellman, Elliptic curve cryptography, etc. The traditional cryptographic techniques are unsuitable for securing sensitive data with great accuracy. To increase the security of sensitive data, we add a layer of protection in the form of the steganography technique, which hides the data inside an image. We proposed an integrated system for securing sensitive data faster to achieve more accuracy.
