Abstract
Data security needs a comprehensive system design approach that combines legal, administrative, and technical protection. These laws generally contain complete rules and principles relevant to the collecting, storing, and using personal information in line with international standards on privacy and data protection. Personal data should be legally collected for a specified reason and not be used without authorization for unlawful monitoring or profiling by governments or third parties. In advocacy and open data activity, increasing attention has been placed on privacy problems. To secure the protection of this data, the Privacy Law (PL) and the Regulations typically put forth industrial and technical standards on IT systems that hold and handle personal data. Concerns about information privacy are genuine, valid, and exacerbated on the Internet of Things (IoT) and Cyber-Physical Systems (CPS). This article suggests that compliance with IoT and CPS Data Privacy (DP) at technical and non-technical levels should be dealt with. The proposed architecture is then coupled with a reference framework for the business architecture to offer a DP-IoT model focused on the industry and technology and positioned to comply with the Personal Information Protection Act (POPI). Therefore, methods are necessary to protect data privacy based on both system and organizational reference designs. In the end, users should have specific rights to information about them, including the capacity and method to seek recourse to protect such rights, to acquire and amend incorrect details. The DP-IoT model shows a privacy ratio of 92.6%, scalability ratio of 91.5, data management ratio of 94.3%, data protection ratio of 96.7%, customer satisfaction rate of 92.2 %, attack prevention ratio of 95.5% and energy consumption ratio of 25.5 % compared to the existing methods.
