This study presents a novel three-tier adaptive video steganography method for secure data transmission. The approach achieves high hiding ratios up to 28.125% while maintaining video quality, enhancing data security.

Area of Science:

  • Computer Science
  • Information Security
  • Digital Communication

Background:

  • Growing internet usage necessitates robust data security measures.
  • Cryptography and steganography are key techniques for secure data transmission.
  • Existing methods may lack adaptive security or sufficient hiding capacity.

Purpose of the Study:

  • To introduce an innovative adaptive video steganography technique with three security tiers.
  • To enhance secure communication by effectively concealing information within video frames.
  • To provide users with flexible control over embedding capacity.

Main Methods:

  • Spatial domain embedding in cover video frames.
  • Adaptive Control Block (ACB) for flexible embedding capacity.

  • Chaotic Key Generator (CKG) using logistic and sine maps for security parameters (PO, FS, RPH).
  • Three-level security: encryption, random frame selection, and random hiding position.

    • Main Results:

    • Achieved adaptive hiding ratios from 7.1% to 28.125% (0.56 to 2.25 bits per pixel).
    • Maintained high video quality with Peak Signal-to-Noise Ratio (PSNR) between 50.25 and 62.05 dB.
    • Demonstrated effective data concealment and secure transmission.

    Conclusions:

    • The proposed adaptive video steganography method offers a robust solution for secure data transmission.
    • The three-tier security system effectively protects hidden data.
    • The method balances high hiding capacity with imperceptible video quality degradation.
