This paper is proposed about the watermarking technique based on the mobile camera phone for search out injudicious photographers and tracing unlawful distribution of the pictures by mobile phone camera. The proposed algorithm is designed considering a mobile embedded-environments using Haar wavelet transform and ARM9 embedded processor core, therefore it satisfies real-time processing and the blind watermarking. After load this watermarking algorithm to mobile camera phone test board, as experimental results, we confirmed that robust-ness and invisibility of watermark embedded in images by mobile phone camera are superior.
