Copyright Declaration for Leaked Numeric Data

摘要

A new copyright declaration method for leaked numeric data is proposed. The proposed method embeds an elaborate rights witness into the to-be-protected numeric data to generate the resulting protected numeric data. Once the protected numeric data are leaked or stealthily copied for illegitimate uses, our method is able to extract the embedded rights witness that can be derived from the values of copied numeric data to declare the copyright. The rights witness is derived based on polynomial interpolation which provides the trustworthy security in the proposed method. Experimental results and discussions are provided to prove the feasibility and effectiveness of the proposed method.
