  <description><![CDATA[Winner of the Best Paper Award in the conferenceWith the rapid implementation of Cloud-based Electronic Health Record (EHR) systems, health providers are specifically concerned about handling data privacy on the cloud. Existing methods have either scalability issues by requiring that patients grant access to their medical data or a trust issue by having a single authority, thereby creating the problem of a single point of attack. Hence there is a need to develop an EHR system that addresses t...]]></description>

  <description><![CDATA[Medical organizations find it challenging to adopt cloud-based Electronic Health Records (EHR) services due to the risk of data breaches and the resulting compromise of patient data. Existing authorization models follow a patient-centric approach for EHR management, where the responsibility of authorizing data access is handled at the patient's end. This creates a significant overhead for the patient who must authorize every access of their health record. This is not practical given that mult...]]></description>

  <description><![CDATA[With the advent of smart farming, individual farmers have started adopting the concepts of agriculture 4.0. Modern smart farms leverage technologies like big data, Cyber Physical Systems (CPS), Artificial Intelligence (AI), blockchain, etc. The use of these technologies has left these smart farms susceptible to cyber-attacks. In order to help secure the smart farm ecosystem in this paper, we develop a smart farming ontology. Our ontology helps represent various physical entities like sensors,...]]></description>

  <description><![CDATA[Attribute Based Access Control (ABAC) models are designed with the intention to overcome the shortcomings of classical access control models (DAC, MAC and RBAC) and unifying their advantages. In ABAC, the access control is provided based on generic attributes of entities. Many organizational security policies condition access decisions on attributes. OWL can be used to formally define and process security policies that can be captured using ABAC models. We have defined models, domains, data a...]]></description>
