Multimedia streaming service has been growing rapidly. The content authentication for multimedia streams is an important issue. Several content authentication schemes for multimedia streams have been developed. However, the developed authentication schemes do not allow modification of the content after authentication material is generated. Multimedia content producers and streaming service providers are different in many cases. Multimedia content is produced by the content producer and streaming service is performed by the streaming service provider. The authentication material of the content is generated by the content producer. The content producer may allow the streaming service provider to modify certain parts of the content after the authentication material is generated. We propose a content authentication scheme for multimedia streams in this paper. The proposed scheme allows modification of specific parts of the content by the streaming service provider after the authentication material is generated.
