Earth vs EdGuard

NASA's Earth Now is an application that visualizes recent global climate data from Earth Science satellites, including surface air temperature, carbon dioxide, carbon monoxide, ozone, and water vapor as well as gravity and sea level variations. Data sets are visually described using "false color" maps. Color-coded legends are provided to indicate relative strength or weakness of an environmental condition. The resulting 3D model of the Earth may be rotated by a single finger stroke, and may also be zoomed in or out by pinching 2 fingers. It was developed by the Earth Science Communications and Visualization Technology Applications and Development Teams at NASA's Jet Propulsion Laboratory, with support from NASA Headquarters.

EdGuard is a cognitive biometric authentication platform designed for academic institutions. Verify student identity before exams, grant disbursements, and supervised sessions — in under 45 seconds. HOW IT WORKS: 1. Enrol — Register your identity once: face capture, voice sample, cognitive baseline, and post-quantum signature. 2. Verify for Payment — Confirm identity before releasing a student grant or scholarship. 3. Exam Session — Open a continuously supervised exam with live biometric monitoring. KEY FEATURES: - Face recognition with liveness detection - Voice sample authentication - Cognitive reaction-time test (bot-proof) - Post-quantum cryptographic signing (NIST FIPS 203/204) - Offline-first architecture — works in low-connectivity environments - Multilingual support (English, Zulu, Xhosa) EdGuard prevents identity fraud at the source — protecting students, institutions, and disbursement programmes.
