本文提出了一个增强的系统，用于保护个人计算机上的敏感文本数据受益于这两种技术的组合：密码学和隐写术。该系统的安全性是通过涉及RSA加密，然后基于视频的隐写作为两个顺序层，以确保最佳的安全性，从两者中获得的优点。该研究对系统进行了建模，并对其进行了测试，以探索安全性，容量和数据依赖性之间的关系。实验涵盖了在15个不同大小的视频中测试数据安全性，显示了有趣的结果。该研究给出了容量与安全性的增强，作为强制执行的不可避免的权衡。工作的独特性是在显示不同的措施，允许用户和应用程序的决策者选择。测试提供了接受1-LSB、2-LSB和3-LSB方法的安全性的所有可能性，详细说明了它们对封面视频的影响。主要结果证明了采用3-LSB方法的适用性，以提供可接受的安全性和实际容量，使3-LSB在1-LSB和2-LSB技术中胜出。
This paper proposed an enhanced system for securing sensitive text-data on personal computer benefitting from the combination of both techniques: cryptography and steganography. The system security is generated by involving RSA cryptography followed by video based steganography as two sequential layers to insure best possible security gaining the advantages from both. The study modeled the system and implemented it to be tested to explore the relation between security, capacity and data dependency. The experimentations covered testing securing data within 15 different size videos showing interesting results. The research gave enhancement to capacity vs. security, as enforced unavoidable tradeoff. The work uniqueness is presented in showing different measures allowing the user and application to be the decision maker to choose. The tests provided all possibilities of accepting security of 1-LSB, 2-LSB, and 3-LSB methods detailing their effects on the cover video. The main outcome proved applicability to be adopting 3-LSB approach to give acceptable security with practical capacity preferred making 3-LSB winning among 1-LSB and 2-LSB techniques.
