在这项工作中，我们研究了具有随机参数的退化广播信道的识别问题。当编码器和非退化解码器非因果地知道随机参数时，在识别能力区域上导出内界和外界。给出了数字水印技术的应用建议。特别是，该模型描述了水印应该由私人用户和公共用户识别的情况。
In this work we study the problem of identification via the degraded broadcast channel with random parameters. Inner and outer bounds are derived on the identification capacity region when the random parameters are known non-causally to the encoder and to the non-degraded decoder. Applications to watermarking are suggested. In particular, this model describes the situation when watermarks are supposed to be identified by both private and public users.
