The method has some characteristics:(1) it adapts to medical images authentication due to the high Signal-to-Noise when the watermark was embedded into images.(2) It ensures the fragileness of watermark when it combines with the statistical information of wavelet coefficient to choose the embedding position.(3) It has a strong localization ability for tampering because of the characteristics of wavelet decomposition in the space-frequency domain.(4) It uses the secret key which can resist the malice attack even if opening the algorithm completely to protect the proposed method.

The electrochemical results indicated that the interaction between TH and CT-DNA is in the intercalative mode in the pH 7.2 phosphate buffer solution, but both intercalative and electrostatic modes exist in the pH 6.5 phosphate buffer solution. Fluorescence spectroscopic results showed that the fluorescence intensity of TH is efficiently quenched by CT-DNA bases.
