Application of Fractional Calculus in Digital Watermarking
YU Sheng-lin · Computer Technology and Development · 2008
A fractional calculus-based digital watermarking system model is proposed and realized.Using the fractional calculus operations order v as the key of watermarking embedding and extraction,and the embedded watermarking is good at invisible.About the information extraction side,if we do not know the exact fractional calculus computing order,it will be impossible to complete watermarking extraction,thus ensuring the effective and confidential communication between the sender and the legitimate receiver.Using Matlab to execute computer simulation confirmed that the fractional calculus-based digital watermarking system is effective and feasible.
