# Secure Image Transmission Using Multilevel Chaotic Encryption and Video Steganography
## 8 Conclusions  
This paper proposes a secure and efficient novel video steganography system that integrates features emphasizing security and efficiency by incorporating AES encryption alongside a key generation mechanism based on a multilevel chaotic map. The proposed system is characterized by high security, robustness, and imperceptibility levels, as demonstrated and validated by various security and quality assessment metrics. The experimental findings indicate that the proposed method achieves high elevated PSNR values, indicating minimal distortion in stego-frames, while the results of entropy and chi-square tests confirm the strong randomness in the encrypted text. Furthermore, the linear selection approach used in information pixel embedding was optimized, outperforming existing methods in terms of superior efficiency and security. Additionally, NIST randomness tests validated the unpredictability of the generated keys, ensuring protection against cryptanalysis. The proposed system shows potential for a vast array of applications in practice, where high-level security and only perceptible data are necessary. In healthcare, it can ensure that diagnostic images, like MRIs or X-rays, are securely sent between hospitals while preserving patient privacy. On the battlefield, the technology could integrate encrypted intelligence images into drone surveillance video for clandestine communication. Moreover, the government cloud can also use the method to prevent attacks or steganalysis on confidential visual documents stored there. The system's low distortion and calculation complexity can also be flexibly used in IoT-based security cameras and video observation systems. Although the proposed scheme involves more computational work regarding multilevel chaotic key generation and AES encryption, the trade-off is worth it for enhancing security and data imperceptibility. Computation time and memory costs are acceptable for practical real-time applications. Therefore, the gains in the cryptographic performance are justified because they outweigh the additional moderate-cost resources that make this system suitable for the secure communication of multimedia. In addition, future cryptographic systems must consider the evolving threat of quantum computing, which can potentially break traditional encryption algorithms like RSA and AES through [PERSON]'s algorithm. Although AES-256 remains currently secure, future extensions may require post-quantum cryptographic primitives. Our system's reliance on dynamic, chaotic key generation adds a layer of complexity that may offer partial resistance against quantum attacks.  
Comparative analysis with previous studies confirms that the proposed system offers a balance between embedding capacity, security, and computational efficiency. Future work may focus on enhancing embedding capacity while maintaining high imperceptibility and security.
