Study on Digital Watermarking in the Oracle Bone Inscriptions Rubbings

As an important means of information security and copyright protection, digital watermarking technology has been extensive researched and widely applied; it proves data's ownership or integrity by embedding secret information into raw data, thus achieves the purpose of copyright protection and information security. Based on the analysis and research of wavelet transformation, this study achieves to embed digital watermarking into the Oracle bone inscriptions rubbings. Experimental results show that this method has a stronger robustness to altering and cutting of images.
