Implementation of Quantum Simulation-Based Image Steganography in Mobile Applications and Website for Student Learning

Data protection and multimedia content security have grown to be critical and current concerns in people’s lives in this sophisticated digital era. Awareness of the importance of keeping personal information private in the online world has become very significant. A long-term strategy that strives to raise public comprehension and awareness of the risks connected with sharing personal content online is required to overcome this problem. Educating people about steganography or information hiding methods through online learning resources is one possible option. There are three image steganography methods that will be implemented, namely quantum spread spectrum, quantum discrete cosine transforms, and quantum wavelet. The designed website and mobile application incorporate practical features for embedding and extracting hidden data within images. Additionally, provide material for understanding steganography, quantum technology, and an explanation of the three methods applied. This paper involves functionality testing to check the buttons and features on the website and mobile application can run properly. Then, user satisfaction testing is carried out to find the experience and impression of users in using the application and website that has been made. The test results show that the quantum-based information hiding application has successfully provided good service and insight to society. With this approach, it is hoped that people can increase their awareness of the importance of data security and multimedia content.
