STEGANOGRAPHY IMPLEMENTATION ON ANDROID REACT NATIVE USING LSB ALGORITHM

Abstract

The security and authenticity of data are very critical in the current digital era. This final project explores the field of image steganography, focusing on how the Least Significant Bit (LSB) methods are used in an Android application. The main goal was to create a simple yet secure mobile software that would enable users to covertly insert messages into images, improving data security and integrity. The cross-platform features of React Native were intentionally utilized throughout the development stage. This decision made sure that users of different Android devices will have a similar experience. The selected LSB technique is notable for its capacity to increase data security while preserving the original quality of the host picture, making the embedded message almost unnoticeable. Evaluation results from the application confirm its ability to maintain picture quality while safely obscuring data. In a larger sense, this project highlights the importance of steganography in the linked digital world of today. This project gives a peek into the potential of steganography as a crucial instrument for modern data security and communication strategies by demonstrating its usefulness as a deterrent against cyber vulnerabilities and as a medium for secret communication.
