Interactive segmentation with hidden object based annotations : towards smart media
Autor: Rytsar, Yuriy, Voloshynovskyy, Svyatoslav, Ehrler, Frédéric, Pun, Thierry
Publikováno v: Proceedings of SPIE Electronic Imaging, Storage and Retrieval Methods and Applications for Multimedia
In this paper a novel "Smart Media" concept for semantic-based multimedia security and management is proposed. This concept is based on interactive object segmentation (considered as side information in visual human-computer interface) with hidden ob

StegoWall: Blind Statistical Detection of Hidden Data
Autor: Voloshynovskyy, Svyatoslav, Herrigel, Alexander, Rytsar, Yuriy, Pun, Thierry
Publikováno v: Proceedings of SPIE Photonics West, Electronic Imaging 2002, Security and Watermarking of Multimedia Contents IV pp. 57-68
Novel functional possibilities, provided by recent data hiding technologies, carry out the danger of uncontrolled (unauthorized) and unlimited information exchange that might be used by people with unfriendly interests. The multimedia industry as wel

The Watermark Template Attack
Autor: Herrigel, Alexander, Voloshynovskyy, Svyatoslav, Rytsar, Yuriy
Publikováno v: SPIE Photonics West, Electronic Imaging 2001, Security and Watermarking of Multimedia Contents III pp. 4314-4346
This paper presents a new attack, called the watermark template attach, for watermarked images. In contrast to the Stirmark benchmark, this attack does not severely reduce the quality of the image. This attack maintains, therefore, the commercial val

Cryptography and steganography of video information in modern communications
Autor: Grytskiv, Zenon, Voloshynovskyy, Svyatoslav, Rytsar, Yuriy
Publikováno v: Facta Universitatis-Series: Electronics and Energetics, Vol. 11, No 1 (1998) pp. 115-125
In this paper image cryptography and steganography performed in frequency domain using random phase mask encoding are presented. The use of random phase mask allows to deccorrelate initial image and makes it unrecognized. This property is used for pr
