AI Logic & Security

Attendr implements five Knowledge Representation (KR) rules using First-Order Logic to ensure secure, fraud-proof attendance:

KR Rule #1: Face Recognition
∀x ((CapturedFace(x) ∧ MatchStored(x)) → FaceMatch(x))
KR Rule #2: Location Verification
∀x[(Student(x) ∧ IsWithinAllowedArea(x)) → VerifiedLocation(x)]
KR Rule #3: Device Readiness
∀d ((CameraOn(d) ∧ GPSOn(d)) → StartVerification(d))
KR Rule #4: Attendance Validation
∀x ((FaceMatch(x) ∧ LocationValid(x)) → GrantCodeAccess(x))
KR Rule #5: Auto-Refresh Code Confirmation
∀x ((ValidCodeEntry(User,x) ∧ WithinCycle(Code,x)) → MarkPresent(System,x))
