Title

Platrack: A Blockchain-Enabled IoT Supply Chain Traceability System Integrating OCR and Geolocation

Abstract

Supply chain operations require accurate, transparent, and traceable records as goods move between suppliers and warehouses. Conventional systems may not adequately verify operational data at the point of entry, creating risks of inaccurate or invalid records. This study presents Platrack, a mobile Internet of Things (IoT)-based application for logistics traceability that integrates blockchain, optical character recognition (OCR), and geolocation. The system uses OCR to recognize vehicle license plates at departure and OpenStreetMap-based geolocation to validate the route from supplier pickup to warehouse check-in. Validated vehicle, location, and transaction data are recorded on a blockchain ledger to support data integrity and traceability. The system’s license plate recognition performance is evaluated using the detection rate (DR), false positive rate (FPR), and false negative rate (FNR). The implementation demonstrates how combining visual and location-based data validation with blockchain recording can support a tamper-evident audit trail for logistics transactions. Platrack offers an approach to improving the security and transparency of supply chain records.

Judul

Platrack: Sistem Pelacakan Rantai Pasokan Berbasis IoT yang Didukung Blockchain Mengintegrasikan OCR dan Geolokasi

Abstrak

Operasi rantai pasokan memerlukan catatan yang akurat, transparan, dan dapat dilacak saat barang bergerak antara pemasok dan gudang. Sistem konvensional mungkin tidak cukup memverifikasi data operasional pada titik masuk, menciptakan risiko catatan yang tidak akurat atau tidak valid. Penelitian ini mempersembahkan Platrack, aplikasi berbasis Internet of Things (IoT) untuk pelacakan logistik yang mengintegrasikan blockchain, pengenalan karakter optik (OCR), dan geolokasi. Sistem ini menggunakan OCR untuk mengenali plat nomor kendaraan saat keberangkatan dan geolokasi berbasis OpenStreetMap untuk memvalidasi rute dari pengambilan pemasok hingga check-in gudang. Data kendaraan, lokasi, dan transaksi yang telah divalidasi dicatat dalam buku besar blockchain untuk mendukung integritas data dan pelacakan. Kinerja pengenalan plat nomor kendaraan sistem dievaluasi menggunakan tingkat deteksi (DR), tingkat positif palsu (FPR), dan tingkat negatif palsu (FNR). Implementasi ini menunjukkan bagaimana menggabungkan validasi data berbasis visual dan lokasi dengan pencatatan blockchain dapat mendukung jejak audit yang tidak dapat diubah untuk transaksi logistik. Platrack menawarkan pendekatan untuk meningkatkan keamanan dan transparansi catatan rantai pasokan.

The abstract describes the evaluation metrics but does not report the results. For a stronger scientific submission, add the DR, FPR, and FNR values, along with the test sample size or evaluation conditions.
