UNIVERSAL DATA CONSENT FIREWALL
Privacy-focused user data access & consent engine
A system built around user-controlled data access, explicit permission policies, and real-time consent auditing.
01 / THE PROBLEM
Applications frequently harvest user data without providing granular, dynamic control over authorization boundaries.
02 / THE CORE CONCEPT
Interposing an authorization firewall proxy that evaluates access requests against user-configured dynamic rules.
03 / TECHNICAL APPROACH
Built a permission evaluation engine that intercepts incoming API requests and verifies cryptographically signed consent tokens.
