The existence of everything is a dynamic process, and its emergence, growth, continuation, and demise are objective existences, including "intangible cultural heritage." With the continuous deepening and development of science and technology, the development of digital acquisition technology, storage technology, remote sensing technology, and spatial modeling technology provides a corresponding realistic basis and platform for the protection of different types of intangible cultural heritage. This paper mainly discusses the application of a variety of modern information technologies in the protection of intangible cultural heritage, deeply discusses the problems existing in digital protection of intangible cultural heritage, analyzes the characteristics of digital protection of intangible cultural heritage, discusses how to better establish the protection platform and management mechanism, and puts forward the application prospect of computer digital technology in the protection of intangible cultural heritage, so as to realize relatively comprehensive digital protection of intangible cultural heritage.  a1574-017X
