Abstract In order to assure the concealment by cryptographic protocols, it is an effective measure prove in a formal logical system. contemporary context of protocol, has be proved using probability theory. There are several concepts One them Bayesian concealment. This study proposes system secret sharing scheme.

Understanding self-concealment, the tendency to actively conceal distressing personal information from others, may be important in developing effective ways to help individuals with suicidal ideation. No published study has yet assessed the relation between self-concealment and suicidal behaviors. Additionally, most self-concealment research has been conducted solely with younger adults. The re...

Although concealment in relationships is commonplace, little is known about its implications for the target of concealment. Two large-scale studies among adolescents and their parents tested the central hypothesis that parents’ perception of child concealment predicts poorer parenting behaviors toward their child. Further, we investigated whether actual child concealment adds to the prediction ...

Video transport over error-prone channels may result in loss or erroneous decoding of the video data. Error concealment is an effective mechanism to reconstruct the video data. In this paper, we review error-concealment methods and introduce a new framework, which we refer to as second-generation error concealment. All the error-concealment methods reconstruct the lost video data by making use ...

Decoding of 3D multi-view video coded bit-streams that are transmitted over noisy channels can suffer from error propagation in the space, time and view domains. To improve the quality of reconstructed 3D video, we propose adaptive Error Concealment (EC) algorithms to conceal the erroneous blocks of intra-coded and inter-coded frames. Our proposed algorithms adapt to the motion characteristics ...

Several shape error concealment techniques for objectbased video have already been proposed in the literature. These techniques, however, are either spatial or temporal, in the sense that only information from one of these domains is considered during the concealment process. While spatial error concealment techniques only use spatially adjacent shape information to perform the concealment, tem...

This paper presents a new, classification-based spatial error concealment algorithm for images. The proposed scheme takes advantage of two state-of-the-art concealment schemes and adaptively selects the best suitable concealment scheme for each corrupted block. Using a simple classification scheme via SVM, our proposed approach outperforms the prior art in terms of the concealment quality and h...
