The application of Face Recognition Technology (FRT) in various sectors has raised significant concerns regarding privacy and data protection, especially in the context of the General Data Protection Regulation (GDPR) 2018 (EU) 2016/679. This article critically evaluates the procedural safeguards mandated by the GDPR for the deployment of FRT.
This research paper examines a critical privacy challenge related to IRREVERSIBILITY — once pii propagates, it cannot be un-propagated.
anonym.plus addresses this through 100% local processing with AES-256-GCM encrypted vault — PII processed and stored locally, never touching any external server.
Once PII propagates, it cannot be un-propagated. The arrow of data only points one direction. PII exposure is a one-way function with no inverse.
Irreducible truth: Information entropy only increases. You cannot recall a broadcast signal. You cannot un-train a neural network. You cannot selectively erase a backup tape. Every deletion mechanism is an approximation — and the original exposure persists.
anonym.plus identifies 200+ entity types including names, email addresses, phone numbers, contact information, browsing identifiers. The local Presidio 2.2.357 + spaCy 3.8.11 architecture uses Presidio 2.2.357 deterministic recognizers with 121 built-in presets for structured identifiers and spaCy 3.8.11 with 23 language models, all running locally via FastAPI sidecar for contextual references.
Redact is recommended for this pain point: removing identifying information prevents creation of shadow profiles by ensuring no third-party PII is included in shared data. Replace provides an alternative — replacing contact details with placeholders preserves document structure while protecting non-users. For scenarios requiring reversibility, Encrypt (AES-256-GCM) enables authorized recovery of original values.
The Tauri 2.x desktop application (Rust + React) processes 7 document formats (PDF, DOCX, XLSX, TXT, CSV, JSON, XML) plus images (Tesseract OCR). AES-256-GCM vault with Argon2id protects all stored data.
This pain point intersects with GDPR Article 14 information for data subjects not directly collected from, Article 6 lawful basis.
anonym.plus’s GDPR (data never leaves device), HIPAA (local processing) compliance coverage, combined with 100% local — data never leaves device hosting, provides documented technical measures organizations can reference in their compliance documentation and regulatory submissions.
