Digital Development of Cultural and Creative Industries Under the Security of 5G Mobile and Communication

With the rapid growth of global 5G technology, it inevitably has a certain impact on the growth of China's cultural industry, and also encourages employees in the cultural industry to innovate and transform China's cultural industry. Various technologies of 5G digital technology have important influence and strong impetus on cultural & creative industries. With the rapid progress of social development, people are gradually attracted by some new things, new media and other forms of content, and their attention to cultural legacy is gradually reduced, which in turn brings a large number of cultural relics, historical buildings, cultural relics, handicrafts, etc. that slowly disappear from people's vision. Under the background of 5G mobile and communication security, this article proposes a digital protection model of cultural legacy based on deep learning (DL). The digital protection model of cultural legacy based on DL can effectively solve the problem of unclear and stereo images, while maintaining the clarity of cultural legacy images, which provides theoretical support for the digital growth of cultural & creative industries.
