This paper shows how to extend RBAC sessions with dynamic aspects to deal with user switch. Users can authenticate using their functions which will create a dynamic session and automatically activate a set of privileges associated with this function. A dynamic session can be joined, leaved, restarted and reused by authorized users. Moreover, a user can switch the session to another user in orde...

This paper demonstrates the enhancement in ;maintainability made possible by introducing metal-level control architectures to production systems. We msess t h e amount of eflort expended in upgrading a rule base through the range referred to b y maintenance staff f o r d e base upgrading. The rule base of an Intelligent C A I System currently in operation that employs the raeta-level control ar...

objectives: this study intended to examine the effectiveness of mindfulness-based cognitive therapy on moderating maladaptive schemas and affective control in students suffering from learning disabilities. methods: this experimental research was conducted using pretest-posttest and a control group. the population included all the female students who  were studying in the koohdasht's middle...

abstract objective: the aim of current study was evaluation of group-based diabetes self-management education (group-based dsme) effectiveness in improving glycemic control among type 2 diabetic patients attending the yazd diabetes research center in 2014. materials and methods: the study design was quasi-experimental with control group.in this study, 62 diabetic patients were randomly allocate...

Significant research has been done in the area of Role Based Access Control [RBAC]. Within this research there has been a thread of work focusing on adding parameters to the role and permissions within RBAC. The primary benefit of parameter support in RBAC comes in the form of a significant increase in specificity in how permissions may be granted. This paper focuses on implementing a parameter...

Separation of duty (SOD) is an important characteristic in the role-based access control (RBAC) system. In view of some issues such as various variations of SOD constraints (SODs), ambiguous relations among constraint states, this paper formally defines several typical SODs and analyzes the transition relations among different SODs states. In combination with a delegation case, it goes an explo...

Role-based access control policies model the users domain by means of complex structures where the roles assumed by the users are specialized into more concrete subroles which inherit properties and authorizations from their parents. In this paper, we describe how to combine these principles and adaptation to provide personalized access to the different types of users of a webbased course. We a...

In large-scale grid environment, the authorization plays a vital role in access control to resources. For the demand of higher dynamicity, complexity and granularity on grid environment, a novel model named dynamic role-based access control (DRBAC) based on RBAC model is presented. DRBAC introduces conceptions of several objects such as rolegraph initial structure, atom role and middle role, an...

Role-based access control associates roles with privileges and users with roles. Changes to these associations are infrequent and explicit. This may not reflect business requirements. Access to an object should not only be based on the identity of the object and the user, but also on the actual task that must be performed, i.e. the context of the work to be done. Context-sensitive access contro...
