Porcelain art is a classic art treasure in the history of human civilization. After thousands of years of development, it carries the wisdom and sweat of the ancients and draws us a masterpiece that spans thousands of years. China is the hometown of porcelain. As the essence of Chinese art, porcelain has retained the traditional artistic characteristics of our country for thousands of years. Porcelain design can not only capture people's living experience and cultural understanding, but also express the thoughts or feelings of predecessors. This thesis aims to study the application of Leizhou kiln porcelain pattern gene extraction and modern design in the secure Internet of Things. The extraction of Leizhou kiln porcelain patterns in this paper is a very rigorous technical work. First, a security IoT monitoring and early warning system must be established. Secondly, a field survey of Leizhou Museum and Zhanjiang City Museum will be carried out to take photos of Leizhou kiln porcelain from various angles, combined with literature. Sort out the first-hand porcelain materials and classify the porcelain according to the age of production. Then use software such as photoshop, Adobe illustrator, CorelDRAW and other software to extract unit patterns from the patterns on the Leizhou kiln porcelain in turn, use symmetry, exaggeration and other basic skeleton deformation processing, refer to the popular color matching, to form a modern and unique pattern. The results of the empirical analysis show that we must use the Internet of Things technology to take safety measures before Leizhou kiln porcelain pattern gene extraction, which can make the safety reach 91%, and we must also apply the extracted patterns to modern designs. It does not mean that the porcelain patterns are directly used. What we want to achieve is an innovative way of inheritance, so that these porcelain patterns will be presented to everyone with a brand-new mental outlook.
