Protection algorithm of face feature using SIFT
人脸特征的SIFT保护算法

With the growing use of face recognition in security and video control domain,there are growing concern about security and privacy of biometrics data.This paper proposes a security algorithm about face feature,which bases on the SIFT feature and random projection.Because the SIFT features are invariant to image rotation,scale and change in illumination,feature extraction is first performed on face images by SIFT algorithm.The SIFT features are transformed using invertible transformation which is generated b...
