This paper is aimed to develop and implement a web-based 3D surface evaluation, analysis and simulation software. The software can provide users from all around the world with a means to conduct surface study through the Internet. The software automatically calculates all 3D surface roughness parameters and has options for the user to view various 2D and 3D graphical representations of the entire surface. All outputs calculated are viewed through a web browser or can be downloaded to a user computer, giving the user a complete numerical and graphical representation of any surface for which they have measured the surface data.

The Internet of Things is the product of the IT industry revolution, following the new wave of the Internet revolution. With the development of IoT technology and its wide application, the security of the Internet of Things has become the most concerned and primary problem in the moment. RFID technology has been widely used in various fields. The application and development of RFID technology cannot be separated from the support of the Internet of Things. However, the Internet of Things based on RFID technology has various problems, including standard issues, security issues, data management issues, etc. The security issues have become the main bottleneck for the future development of the Internet of Things, so it is necessary to focus on security problems at the moment. This paper mainly discusses RFID technology, analyzes the composition of IoT system based on RFID technology, and analyzes the main problems of Internet of Things based on RFID technology. Finally, it proposes specific measures for the security of Internet of Things.
