Access Control Techniques for Secured Dynamic Collaboration in Cloud

Secured and dynamic collaboration is a challenging issue in cloud computing environment. Moreover, security in cloud database can be provided using access control techniques. Secured communication in cloud environment can be made effective by providing dynamic and access control based collaboration for effective decision making. Therefore, the storage and retrieval with access control has been implemented in this work using new spatio-temporal constraints for providing dynamic and secured collaboration. The main advantages of the proposed model are that, it provides dynamic and secured collaboration and suitable access control policies using new spatio-temporal constraints to enhance the security effectively.
