A Wavelet-Based Digital Watermarking Algorithm for Packaging Security

Abstract:

In this paper, a wavelet-based digital watermark algorithm for packaging security is proposed. In the algorithm, digital watermark is embedded in the color image CMYK mode, the method based on the discrete wavelet transform (DWT) can point to point semi-adaptive repeated embed digital watermark. Digital watermark that embedded in a color image can be extracted after printing, scanning and pre-processing the color image. The experimental results show that watermark extraction’s effect is acceptable, so the algorithm can achieve the purpose of the anti-counterfeiting for packaging printing. In addition the algorithm is robust enough against various kinds of attacks such as salt&pepper noise addition, JPEG compression, image crop and so on.
