Article Synopsis
- The study addresses the growing concern of data security in internet usage by introducing an innovative adaptive video steganography technique with three levels of security.
- This method allows users to embed hidden information in video frames, achieving a high hiding ratio of up to 28.125% while ensuring the video's quality is not compromised.
- The technique utilizes a chaotic key generator for secure data processing and encryption, with experimental results showing effective data embedding and maintaining excellent video quality as indicated by a high peak signal-to-noise ratio (PSNR).

Medical images of patients must be securely transmitted and kept private in telemedicine. To secure such medical images, this paper proposes a single round chaotic image encryption scheme based on a permutation-diffusion structure. A combined chaotic key generator (CCKG) is proposed to enhance key sensitivity and generation in order to improve the security of medical images to be encrypted.
