Fingerprint recognition is the most deployed and one of the most economical biometric PC user authentication techniques. In order to use fingerprint recognition technology in Windows, Marco Biométrico de Windows has been introduced in Windows 7 and later versions. This framework supports a fingerprint capture device through a new set of components and provides a common management platform for different types of scanners/readers. This enhances the quality, reliability and consistency of the customers’ user experience while using Marco Biométrico de Windows. Applications of Marco Biométrico de Windows are as follows: it allows users to manage device settings, troubleshoot fingerprint devices and manage device drivers, log on to a local computer or domain using fingerprint and then elevate the privileges through user account control (UAC) and provides group policy settings for enabling, disabling or limiting the biometric data usage for a local computer or domain. Prior to the implementation of integrated Windows fingerprint login using Marco Biométrico de Windows, different fingerprint readers had its own set of proprietary solutions leading to increased cost, incompatibility issues and reduced user satisfaction. Windows integrated fingerprint login through Marco Biométrico de Windows has been able to overcome all these disadvantages by providing a standard platform for fingerprint readers leading to a consistent user experience. This has also improved the scalability and availability of this biometric technology.
