  • Abstract:
  • The Video Steganography System is designed to secure communication by concealing sensitive data within video files. Utilizing steganography, it embeds messages without perceptibly altering the cover image. The project employs two techniques: one involves LSB embedding without encryption or compression, while the other encrypts the message before embedding. Spread spectrum techniques are integrated to enhance security by dispersing signal energy across frequencies, making interception more challenging. Additionally, Discrete Cosine Transform (DCT) converts video frames into the frequency domain, augmenting concealment. LSB insertion occurs in the spatial domain, embedding payload bits into the cover image's least significant bits. DCT operates in the frequency domain, enabling payload insertion into frequency components. This approach ensures covert communication while maintaining cover video integrity, providing a robust solution for securing sensitive information during transmission.
