A Video Watermark Achievement Algorithm Based on Content of the Video Sub-Region
نویسندگان
چکیده
Resisting collusion attack is one of important performances of video watermark algorithm. This paper presents a novel video watermark algorithm based on the visual features of the host video. The proposed algorithm embeds watermark on the DWT coefficients of sub-regions. The mechanism of JND (just-noticeable distortion) is used to attenuate the embedding strength in the sub-region. Experimental results show the proposed scheme can effectively resist two types of linear collusion attacks while still being robust, stable and imperceptible.

A chaos-based video watermarking algorithm
The intriguing characteristics of chaotic maps have prompted researchers to use these sequences in watermarking systems to good effect. In this paper we aim to use a tent map to encrypt the binary logo to achieve a like-noise signal. This approach makes extraction of the watermark signal by potential attacker very hard. Embedding locations are selected based on certain principles. Experimental ...
متن کاملTwo Novel Chaos-Based Algorithms for Image and Video Watermarking
In this paper we introduce two innovative image and video watermarking algorithms. The paper’s main emphasis is on the use of chaotic maps to boost the algorithms’ security and resistance against attacks. By encrypting the watermark information in a one dimensional chaotic map, we make the extraction of watermark for potential attackers very hard. In another approach, we select embedding po...
متن کاملRobust multiplicative video watermarking using statistical modeling
The present paper is intended to present a robust multiplicative video watermarking scheme. In this regard, the video signal is segmented into 3-D blocks like cubes, and then, the 3-D wavelet transform is applied to each block. The low frequency components of the wavelet coefficients are then used for data embedding to make the process robust against both malicious and unintentional attacks. Th...
متن کاملA Novel Caching Strategy in Video-on-Demand (VoD) Peer-to-Peer (P2P) Networks Based on Complex Network Theory
The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...
