Blockchain-Secured Attendance
Tamper-Evident Cryptographic Verification System
A tamper-evident, cryptographic attendance verification infrastructure engineered to prevent proxy signing and attendance fraud. Integrates SHA-256 hash chaining, device fingerprinting, geofenced GPS verification, and Web3 anchoring.
Core Security Features
SHA-256 Hash Chain
Each attendance record cryptographically references the SHA-256 hash of the previous record, creating an immutable chain of evidence.
Device Fingerprinting
Captures unique hardware fingerprints from the accessing device to verify physical presence and prevent proxy signing.
Geofenced GPS Verification
Validates that the student's location falls within pre-defined geographic boundaries (e.g., LAUTECH campus) before accepting attendance.
Web3 Immutable Anchoring
Records anchored to Web3 infrastructure ensure that attendance data cannot be modified retroactively without breaking the chain.
AI-Assisted Administration
Intelligent administrative dashboard for monitoring attendance patterns, detecting anomalies, and generating verification reports.
