Sridevi Tengale, Padmapriya Patil . Wavelet Signature for Image and Document Authentication. International conference on Green Computing and Technology. ICGCT, 3 (October 2013), 43-48.
This paper takes a content-based robust and secure image and document authentication technique which makes use of structural digital signature scalability in order to achieve a good tradeoff between security and data transfer. Here the multi-scale features are used to make digital signatures robust to image degradations and key dependent parametric wavelet filters are employed to improve the security against forgery attacks based on the wavelet transform due to its excellent multi-scale and precise localization properties.
