Abstract—This paper proposed a robust public-key watermarking algorithm based on contourlet transform and its application in coal mining information construction combining the practice. A solution scheme combining the robust watermarking technology and Hash algorithm was proposed to meet the robustness and security requirements of the Electric Equipment Operation Tickets (EEOT). The scheme used the certification information which generated by Hash algorithm, and it was embedded into its image using robust public-key digital watermarking algorithm, so the EEOT contents can be double authenticated. Hash algorithm adopted the MD5 algorithm. The solution scheme was discussed in detail. After the contourlet transform and watermark signal were introduced, the watermark embedment and authentication processes were shown. Maximum capacity of watermarking algorithm was calculated that showed hash value can be hidden in. Experiments were done also shown that the watermarking algorithm is robust against common signal process. Key codes were shown in appendix. Finally, the conclusion was given.
