摘要： Techniques for generating a distorted template for a given facial image are provided. First, at least one facial feature point from a given facial image is selected. The selected facial feature has location information associated therewith. A representation of a region proximate to the selected facial feature point is then generated. Next, the location information associated with the selected facial feature point and/or the representation of the region proximate to the selected facial feature point are distorted. A distorted template is then formed, wherein the distorted template comprises the distorted location information associated with the selected facial feature point and/or the distorted representation of the region proximate to the selected facial feature point.

摘要： A computer system and method determines the force and/or torque applied during the image acquisition stage of a biometric characteristic. Images with very high or very low pressure or high shear torque are rejected and user/operator is notified to re-acquire the image. Alternatively, the application of force and torque by the subject is restricted mechanically so that the images are acquired while the force and/or torque are within acceptable ranges.

摘要： Techniques for generating a distorted fingerprint representation for a given fingerprint image are provided. First, at least one fingerprint feature point from a given fingerprint image is selected. At least one representation of a region proximate to the selected fingerprint feature point is then generated. Next, the representation of the region proximate to the selected fingerprint feature point is distorted. The distortion comprises applying a random projection to the representation to generate a randomly projected representation of the region proximate to the selected fingerprint feature point. A distorted template is then formed, wherein the distorted template comprises the randomly projected representation of the region proximate to the selected fingerprint feature point.

摘要： A method to hide small messages in a wavelet compressed fingerprint image is presented. The method is characterized by random placement of the message bits in the compressed and quantized indices. The compressed image can be decompressed by any certified decompressor without any visible difference. However, the decoder aware of the decompression can only retrieve the hidden message in the image and additionally decompress the image without any error in pixel values.
