5 G message will greatly strengthen the communication capabilities of multimedia messages. The risk of bad information based on 5 G message will increase. Existing bad information governance methods cannot fully cope. In order to improve the existing bad information recognition ability
it is necessary to introduce the latest research results in the field of artificial intelligence to upgrade the existing bad information governance technology. This article summarizes and analyzes in detail the various technologies in the field of artificial intelligence that have value for bad multimedia recognition
and comprehensively analyzes its principles and specific application scenarios. Based on these technologies
the ability to identify bad multimedia messages can be greatly improved
providing sufficient content security for future 5 G new messages.
