Nexa|Face™ – Facial Recognition Software

Biometric Algorithms and SDKs for Facial Recognition and Authentication

Nexa|Face™ provides high-performance biometric algorithms for multistage facial recognition and identification or rapid, high-volume face authentication.

Nexa SDKs provide biometric algorithms for fast and accurate biometric identification and authentication. They are reliable, configurable, and easy to use, complemented by a level of technical support that has helped make Aware a trusted provider of high-quality biometric enrollment and workflow software for over twenty years.

Nexa SDKs are designed to be easily configured towards optimization of a system for a given application, database, computing platform, and operational environment. They include configuration tools that help quantify system performance, identify opportunities for improvement, and continuously optimize the system.

Nexa SDKs can be deployed on the Astra™ Automated Biometric Identification System (ABIS), a scalable biometric recognition and authentication platform that enables cluster computing optimized for rapid biometric search of extremely large databases, high-volume biometric authentication, as well as identity resolution.

Aware’s SequenceCheck, PreFace, and IrisCheck SDKs can be used in concert with Nexa libraries to perform optional quality assurance and preprocessing for enhanced fingerprint, face, and iris search functionality and performance.
