Security, data ownership & compliance: the hidden cost

Understanding data flow and compliance implications reveals primary long-term considerations often overlooked during initial evaluations and vendor selection processes.

OpenALPR: data hosted on Third-Party Systems

OpenALPR’s cloud-based processing model introduces inherent privacy risks as license plate data travels through third-party servers for analysis. This architecture creates potential compliance gaps for organizations handling sensitive vehicle information. 

Data residency requirements, audit trails, and user consent mechanisms may not align with enterprise security policies or regulatory mandates like GDPR, CCPA, or industry-specific requirements. The lack of control over data processing locations, retention policies, and access logs can expose organizations to regulatory violations and security breaches.

Custom: full control of PII, GDPR/HIPAA compliance

Custom solutions provide complete control over data processing, storage, and retention policies, enabling organizations to maintain data sovereignty and meet strict compliance requirements. On-premise processing eliminates third-party data exposure while enabling comprehensive audit trails and user consent management. 

This approach proves essential for organizations requiring GDPR Article 25 compliance, HIPAA data protection, or government security clearance protocols. Full data ownership ensures compliance with evolving privacy regulations and enables specific retention schedules and access controls.

Folio3’s expertise in secure AI systems ensures ALPR implementations meet the highest security standards through encrypted data transmission, secure model hosting, and comprehensive access controls. Our compliance framework addresses GDPR, HIPAA, SOC 2, and government security requirements while maintaining optimal performance.

Total cost of ownership (TCO)

Accurate cost analysis requires examining both immediate expenses and long-term operational implications across multi-year deployments and scaling requirements.
