- A rate-distortion problem is considered for a communication system $(f,p鉑i_1)$ with a secondary decoder $p鉑i_2$ to be hindered which uses a different distortion measure from the primary system. The least achievable distortion of the secondary decoder is evaluated for the most secure primary system. Source coding for source with additional outputs to be kept secret from the receiver or wiretappers is also discussed. Security is evaluated by distortion measures instead of the equivocation function used in a previous paper.
