Intent to purchase IoT home security devices: Fear vs privacy.

ABSTRACT: The Internet of Things (IoT) is a widely hyped concept, with its focus on the connection of smart devices to the Internet rather than on people. IoT for consumers is often called the smart home market, and a large part of that market consists of home security devices. Consumers are often motivated to purchase smart home security devices to prevent burglaries, which they fear may lead to damage to their property or threats to their families. However, they also understand that IoT home security devices may be a threat to the privacy of their personal information. To determine the relative roles of fear and privacy concerns in the decision to purchase IoT home security devices, we conducted a survey of American consumers. We used the Theory of Reasoned Action as the theoretical basis for the study. We found that fear positively affected consumer attitudes toward purchasing smart home security devices, while concerns about privacy negatively affected attitudes. We found that attitudes toward purchase, the opinions of important others, and experience with burglaries all affected intent to purchase. We also found that the relationship between privacy concerns and intent to purchase is completely mediated by attitudes, while fear has both direct and indirect effects on intent.

Project description:The latest Internet of Things (IoT) edge-centric architectures allow for unburdening higher layers from part of their computational and data processing requirements. In the specific case of fog computing systems, they reduce greatly the requirements of cloud-centric systems by processing in fog gateways part of the data generated by end devices, thus providing services that were previously offered by a remote cloud. Thanks to recent advances in System-on-Chip (SoC) energy efficiency, it is currently possible to create IoT end devices with enough computational power to process the data generated by their sensors and actuators while providing complex services, which in recent years derived into the development of the mist computing paradigm. To allow mist computing nodes to provide the previously mentioned benefits and guarantee the same level of security as in other architectures, end-to-end standard security mechanisms need to be implemented. In this paper, a high-security energy-efficient fog and mist computing architecture and a testbed are presented and evaluated. The testbed makes use of Transport Layer Security (TLS) 1.2 Elliptic Curve Cryptography (ECC) and Rivest-Shamir-Adleman (RSA) cipher suites (that comply with the yet to come TLS 1.3 standard requirements), which are evaluated and compared in terms of energy consumption and data throughput for a fog gateway and two mist end devices. The obtained results allow a conclusion that ECC outperforms RSA in both energy consumption and data throughput for all the tested security levels. Moreover, the importance of selecting a proper ECC curve is demonstrated, showing that, for the tested devices, some curves present worse energy consumption and data throughput than other curves that provide a higher security level. As a result, this article not only presents a novel mist computing testbed, but also provides guidelines for future researchers to find out efficient and secure implementations for advanced IoT devices.
