Overview of Smart Home Security with Raspberry

In the realm of the Internet of Things (IoT), the term "smart" signifies networks of devices engineered to simplify human life, despite lacking inherent intelligence. These smart applications extend from homes to offices and entire cities, with Internet connectivity as a common but not mandatory feature, especially in residential or office settings. Building upon the prevalent technologies in smart homes and cities, this paper narrows its focus to analyze the applications of Raspberry Pi (RPi) devices. While an exhaustive examination of all RPi applications within the broader context of smart technologies is impractical, the paper centers specifically on Smart Home (SH) security applications. The paper analyzes the papers using traditional and bibliographic network analysis. By analyzing the existing papers, it was found that Raspberry Pi's primary applications in Smart Home Security focus on intrusion detection, surveillance, fire detection, and aiding the elderly, emphasizing its cost-effectiveness. Two security considerations arise: the first involves the security of smart home systems, covering attacks, cryptography, authentication, blockchain, cloud, network security, and privacy; the second leverages smart homes for security, including face recognition, intruder detection, solutions for the elderly, real-time systems, cloud services, communication protocols (mostly MQTT), cost-effective system development, and mobile technologies.
