IoT is an emerging technology and aims to play an important role in saving money, conserving energy, eliminating gap and better monitoring for(More)
Collaborative Working Environments (CWEs) are getting prominence these days. With the increase in the use of collaboration tools and technologies, a lot of sharing and privacy issues have also emerged. Due to its dynamic nature, a CWE needs to adapt the changes into accordingly. In this paper, we have implemented the Adaptive Dynamic Sharing and(More)
Online Social Network facilitate its users to form groups for sharing their personal information, interests and activities with their friends, relatives and others. Such type of information disclosure can cause problems for people in terms of security. Access of different group members is controlled in Online Social Networks to minimize such security risks(More)
Community detection in network is of vital importance to find cohesive subgroups. Node attributes can improve the accuracy of community detection when combined with link information in a graph. Community detection using node attributes has not been investigated in detail. To explore the aforementioned idea, we have adopted an approach by modifying the(More)
Collaborative environments need access control to data and resources to increase working cooperation efficiently yet effectively. Several approaches are proposed and multiple access control models are recommended in this domain. In this paper, four Role-Based Access Control (RBAC) based collaborative models are selected for analysis and comparison. The(More)
Traditionally, colon cancer is diagnosed using microscopic analysis of histopathological colon samples. The manual examination of tissue specimens is not only time consuming, but is also subjective, and depends upon a few factors such as experience and work-load of the histopathologist. Therefore, research community is constantly putting efforts in(More)
