The classical fingerprint recognition system can be compromised at the database and the sensor. Therefore, to beef up security of the fingerprint recognition system, reversible watermarking is proposed to protect these two points. Reversible watermarks thwart manipulations, $${viz}$$ v i z ., copy and replay attacks and ensure that native fingerprint(More)
In this paper, we describe an image watermarking scheme using compressive sensing for detection of image tampering. We exploit dimensionality reduction and inherent computational security offered by compressive sensing. The frequency band containing the high energy is used to compute the hash and then its pseudo-random projections are obtained. These(More)
In this paper, an approach for pose invariant face detection is proposed by estimating the pose of detected face image. The approach comprises of detection of frontal and profile faces, followed by degree of freedom (DoF) identification and accurate estimation of pose. For pose invariant face detection, cascaded structure of Haar-like features along with(More)
