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 — 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.
