Parental monitoring of student safety has become a critical concern in contemporary Libya, requiring reliable technological solutions. This research proposes a hybrid approach for student geolocation monitoring that combines the Haversine formula for accurate great-circle distance calculation with the Levenshtein algorithm for GPS coordinate-string integrity validation. The system was deployed across three educational institutions in Tripoli, Libya, involving 150 parent–student pairs over a 12-week period. The Haversine-based distance estimation achieved a mean absolute error of ±0.8 meters compared with ground-truth measurements. The Levenshtein algorithm detected and corrected 98.4% of corrupted GPS coordinate strings. A post-implementation survey showed that 87% of participating parents (n = 130) reported increased reassurance and satisfaction with their ability to monitor their children’s locations in real time. Overall, the proposed Haversine–Levenshtein hybrid approach offers a practical and integrity-preserving solution tailored to the Libyan educational context.
