KRATOS: Multi-User Multi-Device-Aware Access Control System for the Smart Home
2020Co-Authors: Sikder, Amit Kumar, Babun Leonardo, Celik Z. Berkay, Acar Abbas, Aksu Hidayet, Mcdaniel Patrick, Kirda Engin, Uluagac A. SelcukAbstract:In a smart home system, multiple users have access to multiple devices, typically through a dedicated app installed on a mobile device. Traditional access control mechanisms consider one unique trusted user that controls the access to the devices. However, multi-user multi-device smart home settings pose fundamentally different challenges to traditional single-user systems. For instance, in a multi-user environment, users have conflicting, complex, and dynamically changing demands on multiple devices, which cannot be handled by traditional access control techniques. To address these challenges, in this paper, we introduce Kratos, a novel multiuser and multi-device-aware access control mechanism that allows smart home users to flexibly specify their access control demands. Kratos has three main components: user interaction module, backend server, and Policy Manager. Users can specify their desired access control settings using the interaction module which are translated into access control policies in the backend server. The Policy Manager analyzes these policies and initiates negotiation between users to resolve conflicting demands and generates final policies. We implemented Kratos and evaluated its performance on real smart home deployments featuring multi-user scenarios with a rich set of configurations (309 different policies including 213 demand conflicts and 24 restriction policies). These configurations included five different threats associated with access control mechanisms. Our extensive evaluations show that Kratos is very effective in resolving conflicting access control demands with minimal overhead and robust against different attacks.Comment: Accepted in the 13th ACM Conference on Security and Privacy in Wireless and Mobile Networks (ACM WiSec 2020

proposal for a privacy Policy Manager as architecture for a new privacy enhancing platform
14th ITS Asia-Pacific Regional Conference Kyoto 2017: Mapping ICT into Transformation for the Next Information Society, 2017Co-Authors: Haruo Takasaki, Toru Nakamura, Shinsaku KiyomotoAbstract:Refinement of the legal framework that balancesthe protection and usage of personal data in online and offline services has been discussed globally. On the other hand, because of information asymmetry between users and service providers and bounded rationality of users, the existing notice-and-consent mechanism (Solove’s privacy self-management model) has proven inadequate in itseffectiveness. This research contributes to solvingthe abovementioned issues usinga complementary technical system(named Privacy Policy Manager). The Privacy Policy Manager creates users’privacy policies based on theirpreferences and supports them incontrollingdata disclosure and data usage in accordance with thesepolicies.

PPM: Privacy Policy Manager for Personalized Services
2013Co-Authors: Shinsaku Kiyomoto, Toru Nakamura, Haruo Takasaki, Ryu Watanabe, Yutaka MiyakeAbstract:In this paper, we introduce a new architecture for personalized services. The architecture separates access control using a user own privacy Policy from data storage for private information, and it supports privacy Policy management by users. We design a core module, the Privacy Policy Manager (PPM). The module includes several functionalities: ID management, privacy Policy management, control of information flows, and recording the flows.
