Title : A NEW APPROACH FOR COMPLEX ENCRYPTING AND DECRYPTING DATA
Pala Supriya, Dr.Ayesha bhanu

Abstract :

In the digital era, safeguarding sensitive information has become more critical than ever. One prominent method for securing data is steganography, which involves concealing a message within an unassuming cover medium, such as an image, to avoid unwanted attention or interception. Unlike encryption, which makes data unreadable, steganography hides the very existence of the message, making the communication covert and imperceptible to the uninitiated eye.This study illustrates a simple and effective technique of text steganography using Python's OpenCV library, a tool adept at image manipulation. The process unfolds in several straightforward steps, beginning with the conversion of the chosen text message into a binary format, a language that is innately understood by computers. Following this, the binary message is intricately woven into the least significant bits (LSBs) of the picture's pixel color channels, a technique which cleverly conceals the message without altering the image's visible properties. To retrieve the concealed message, a reverse process is employed, where the hidden binary bits are extracted from the image and then translated back into its original text format, using ASCII character codes.This method represents a user-friendly approach to steganography, offering a seamless way to secure data transmission by embedding information within an image in a manner that remains both covert and imperceptible, hence promising a robust solution against potential cyber threats.
