Abstract
The Internet of Things (IoT) ecosystem faces persistent security challenges, including poor standardization, weak authentication mechanisms, constrained device resources, significant data privacy risks, and exposure to both cyber and physical threats. The Object-Based Access Control (OBAC) model represents an emerging paradigm that emphasizes object-level autonomy by embedding access control policies directly within objects, in contrast with traditional user- or role-centric approaches such as RBAC and OrBAC. This paper examines the applicability of OBAC for mitigating unauthorized data disclosure in IoT environments and proposes a conceptual architecture in which IoT devices autonomously manage their own access control policies. A simplified Python-based implementation illustrates the feasibility of decentralized security enforcement at the edge.
