Enhancement of Security and Visual Quality in Image Steganography

Abstract: Nowadays in the era of electronic media it is very critical to protect and conceal information. The project makes it better how we conceal confidential information in pictures through a system called image steganography. The idea is to ensure that, the concealed information remains secure and yet the image portrays as being normal and intact to the human eye. We are employing smart algorithms, encryption and the use of technologies such as Python based OpenCV and NumPy to conceal the data in such manner that no intruder can quickly recognize. A web based platform is also a part of the system as the users can transfer images easily as well as embed data and download data as it is secure. The method can be used to achieve high security and decent visual quality, thus, it is applicable in the real world such as encrypted communication or encrypted file sharing.
