QR Code Security and Authentication
Research Guide
What is QR Code Security and Authentication?
QR Code Security and Authentication develops encryption, digital signatures, steganography, and blockchain integration methods to secure QR codes against counterfeiting, tampering, and malicious scanning in applications like payments and identity verification.
Researchers embed cryptographic techniques into QR codes for tamper-proof authentication (Wahsheh and Luccio, 2020, 51 citations). Methods include blockchain patterns for certificate verification (Aini et al., 2020, 69 citations) and steganography for data hiding (Shanthi Rani and Rosemary, 2016, 35 citations). Over 10 papers since 2013 address vulnerabilities in scanners and payloads.
Why It Matters
QR codes enable secure payments and identity checks, but vulnerabilities like malicious URLs cause phishing fraud (Rafsanjani et al., 2023, 33 citations). Blockchain-embedded QR codes prevent fake certificates in education (Aini et al., 2020). Steganography protects medical data exchange (Czuszyński and Rumiński, 2014). Anti-counterfeiting traceability secures agricultural supply chains (Liao and Xu, 2019). Multi-factor authentication strengthens mobile money apps (Ali et al., 2021).
Key Research Challenges
Malicious URL Detection
QR scanners often fail to block phishing links hidden in codes (Rafsanjani et al., 2023). Wahsheh and Luccio (2020) identify privacy leaks in 20+ apps. Real-time filtering needs lightweight models for phones.
Payload Tamper Resistance
Attackers alter encoded data without detection (Shanthi Rani and Rosemary, 2016). Steganography hides info but lacks verification (Dey et al., 2013). Digital signatures add overhead, reducing scan speed.
Blockchain Integration Scalability
Embedding chains into QR limits data capacity and verification speed (Aini et al., 2020). Liao and Xu (2019) note high compute for traceability. Offline authentication remains unsolved.
