ApsaraVideo Live supports multiple security policies to protect the copyright of your live streams, such as stream pushing authentication, streaming authentication, and stream pushing blacklist.
Stream pushing authentication: Stream pushing uses URL signing to protect your uploaded resources from illegal download and theft.
Streaming authentication: Live streaming uses URL signing to protect live streams. After you enable stream pushing authentication in the ApsaraVideo Live console, streaming authentication is automatically enabled. Signed streaming URLs can reduce the risk of hotlinking.
