An efficient data hiding technique in frequency domain by using fresnelet basis

Abstract

A novel method for an efficient data hiding is proposed with more robust retrieving hidden information against various attacks. The proposed method employs the data encryption by appropriate handling of Fresnelet transform for hiding signature information. Different patterns of signatures data are presented for testing the validity of the method. A quantitative evaluation of the quality of extracted signatures is carried out with the correlation function. Also it is analyzed through experiments how the proposed method is effective against the cropping, blurring, sharpened, brightness, Gaussian noise and JPEG compression. Furthermore, the proposed model has the flexibility in using large size of data hiding information as well as supports the multi-frequency domains such as wavelet transform domain for a safe data transmission. © 2012 Newswood Limited.
