There are different types of fingerprint readers on the market, but the basic idea behind each is to measure the physical difference between ridges and valleys.
Biometric functionality[ edit ] Many different aspects of human physiology, chemistry or behavior can be used for biometric authentication. The selection of a particular biometric for use in a specific application involves a weighting of several factors. Universality means that every person using a system should possess the trait.
Uniqueness means the trait should be sufficiently different for individuals in the relevant population such that they can be distinguished from one another. Permanence relates to the manner in which a trait varies over time.
More specifically, a trait with 'good' permanence will be reasonably invariant over time with respect to the specific matching algorithm. Measurability collectability relates to the ease of acquisition or measurement of the trait.
In addition, acquired data should be in a form that permits subsequent processing and extraction of the relevant feature sets. Performance relates to the accuracy, speed, and robustness of technology used see performance section for more details.
Acceptability relates to how well individuals in the relevant population accept the technology such that they are willing to have their biometric trait captured and assessed. Circumvention relates to the ease with which a trait might be imitated using an artifact or substitute.
Proper biometric use is very application dependent. Certain biometrics will be better than others based on the required levels of convenience and security. Three steps are involved in the verification of a person. In the second step, some samples are matched with reference models to generate the genuine and impostor scores and calculate the threshold.
Third step is the testing step. This process may use a smart cardusername or ID number e. PIN to indicate which template should be used for comparison. The system will succeed in identifying the individual if the comparison of the biometric sample to a template in the database falls within a previously set threshold.
ViRDI is the leading provider of biometric core technology, offering secure and convenient solutions for fingerprint and facial recognition, access control and time and attendance. Most Read This Week. Biometric retail technology is ready for its close-up; but are shoppers ready for it? “Smile-to-Pay” facial recognition system now at locations in China. I am planning to verify the user input for my application using the biometric input. I did some research on net and came up with following options of biometric input: Fingerprint Facial Recognition.
Identification mode can be used either for 'positive recognition' so that the user does not have to provide any information about the template to be used or for 'negative recognition' of the person "where the system establishes whether the person is who she implicitly or explicitly denies to be".
The first time an individual uses a biometric system is called enrollment. During the enrollment, biometric information from an individual is captured and stored.The C•CURE integration with EyeLock nano NXT biometric iris reader provides a solution that ensures unparalleled accuracy and security.
nano NXT authenticates up to 20 people per minute, in-motion and at-a-distance with unparalleled accuracy using video, not still pictures, to get an image of your eyes. EyeLock's advanced technology .
