Smart Eye Technology by Sertainty offers an all-in-one screen privacy and self-protecting data sharing platform. It protects data in-transit, at-rest, and in-use. It provides multi-factor biometric-based secure file sharing, ensuring end-to-end security and digital privacy for file exchanges. The Smart Eye app embeds the Sertainty intelligence engine into data-files, transforming them into self-defending data while ensuring data privacy. Continuous facial recognition protects information from unauthorized viewing on any camera-equipped device by preventing screen snooping. It maintains control over downloading and sharing options, monitors access in real-time, and redacts as necessary, even after the file has been opened. It allows users to choose and approve employees and organizations that can view shared files to prevent unauthorized communications. Continuous, multi-factor biometric authentication ensures file access and e-signatures are made only by intended recipients. The embedded Sertainty intelligence engine manages AES 256 encryption and assures real-time end-to-end decisioning and controls from rest, through transit, and in-use.
