Open Access Minimum Perturbation Cost Modulation for Side-Informed Steganography

(PDF 768.5 kb)
A new rule for modulating costs in side-informed steganography is proposed. The modulation factors of costs are determined by the minimum perturbation of the precover to quantize to the desired stego value. This new rule is contrasted with the established way of weighting costs by the difference between the rounding errors to the cover and stego values. Experiments are used to demonstrate that the new rule improves security in ternary side-informed UNIWARD in JPEG domain. The new rule arises naturally as the correct cost modulation for JPEG side-informed steganography with the “trunc” quantizer used in many portable digital imaging devices.

  • For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
