Edge-Level Cookie Consent Enforcement using Bloom Filters in CDN Proxies
Keywords:
Bloom filters, CDN proxies, cookie consent, privacy compliance, tracking prevention, false-positive mitigationAbstract
This article describes a revolutionary edge-of-network cookie consent verification method. Using a lightweight Bloom filter behind CDN proxies. The suggested technique simply blocks cookie tracking without express authorisation. Edge-level request processing is GDPR/CCPA compliant. Compliance is ensured by dynamically updating Bloom filters with opt-out signatures and real-time consent updates. It does this without slowing the user experience. The article discusses important concerns including how to reduce false positives, distribute filter updates across distributed proxy layers, and provide smooth cache invalidation techniques to prevent imposing outdated rules. Many production-scale traffic trace studies show that decision latency is less than a millisecond, unauthorised identity transfers are decreased, SEO ranks, and advertising attribution fidelity stay unchanged. This study proposes scalable, privacy-compliant real-time CDN cookie management.
