Research based on Fourier domain watermarking, to achieve its robustness. Digital watermarking technology to digital works and the effective maintenance of data security, information hiding is an important branch of the field, it is with information security, information hiding, data encryption Dengjun closely related. Digital watermarking has a number of research directions, mainly in terms of image watermarking. Fourier domain-based digital image watermarking technology, is a common watermarking algorithm, which algorithm is simple, the implementation of efficient, effective against attack characteristics.
