Connecting with Broader Systemsto Alice, Bob, and the Warden influence some of the most fundamental aspects, including the way a steganographic system is built and broken and how much information can be securely embedded in a given object. While for simple artificial sources the problem of embedding messages undetectably has been

The quasi-chirp transform is different from the conventional DCT or Fourier transform. It contains multiple frequency components in a single basis of the transform. It d

However, a watermark that is always inserted to low frequencies could be lost during the coding of the audio files with high frequency co
