A multimedia access control language for virtual and ambient intelligence environments

Abstract Access control models are becoming increasingly important in several application domains especially in distributed environments like those addressed by Web Services. Established approaches such as DAC [16] , MAC [16] RBAC [11, 12, 22] and others [6, 5, 15, 1] suggest representing users in different ways (labels, roles, credentials, etc.) in order to facilitate the association of authorization and access control policies. In intelligent and virtual ambient applications, users exist in a controlled environment equipped with multimedia sensors such as cameras and microphones, and use their terminals in several application environments. In this paper, we study the problem of integrating multimedia objects into access control models and particularly role-based ones. Here, we describe a Multimedia Access Control Language (M $^{2}ACL)$ in which users and roles are described by using sets of mul- timedia objects,greatly increasing the flexibility of access control policies and their applicability to virtual and ambient intelligence (AmI environments.We address potential risks related to the use of multimedia objects by defining the concept of filter functions used to aggregate a set of values into a relevant one.Finally,we present a set of functional specification and the experiments conducted to validate the proposed approach.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
