Hamming Code Based Watermarking Scheme for 3D Model Verification

الملخص EN

Due to the explosive growth of the Internet and maturing of 3D hardware techniques, protecting 3D objects becomes a more and more important issue.

In this paper, a public hamming code based fragile watermarking technique is proposed for 3D objects verification.

An adaptive watermark is generated from each cover model by using the hamming code technique.

A simple least significant bit (LSB) substitution technique is employed for watermark embedding.

In the extraction stage, the hamming code based watermark can be verified by using the hamming code checking without embedding any verification information.

Experimental results shows that 100% vertices of the cover model can be watermarked, extracted, and verified.

It also shows that the proposed method can improve security and achieve low distortion of stego object.
