🚀 Warum ich Stego-Lab entwickelt habe:

• Private Archivierung: Ich bette meine sensiblen Dokumente einfach unsichtbar in ganz normale Urlaubsfotos ein. • Urheberrechtsschutz: Als Content Creator nutze ich unsichtbare Signaturen, um meine Werke zu schützen, ohne das Design durch Wasserzeichen zu stören. • Fotografie & Social Media: Ich bereinige meine EXIF-Daten und entferne GPS-Koordinaten, bevor ich Bilder teile, um meinen Standort privat zu halten. • Journalismus & Beweissicherung: Sensibles Material kann ich hochgradig verschlüsselt direkt in Bilddateien verstecken. • Effizienz durch Batch-Modus: Wenn ich hunderte Bilder habe, setze ich Wasserzeichen oder Copyright-Infos für die ganze Sammlung in einem Rutsch.

🛡️ Sicherheit, der du vertrauen kannst:

Deine Daten bleiben auch wirklich deine Daten:

• 100% Lokal: Die App arbeitet vollständig offline. Es gibt keine Cloud, keine externen Server und keinen Netzwerkzugriff. • Echte Verschlüsselung: Optional schütze ich eingebettete Inhalte mit AES-256-CBC – ohne das richtige Passwort ist eine Extraktion rechnerisch ausgeschlossen. • Kein Abo: Alle Profi-Funktionen sind als fairer Einmalkauf verfügbar. Egal ob am Mac im Büro oder unterwegs auf dem iPhone – Stego-Lab bietet dir auf allen Plattformen den gleichen Funktionsumfang.

Enigma style algorithm for text encryption.

VeritasVote is an open-source, tamper-evident in-person voting machine. Fully auditable, cryptographically verifiable, and backed by paper ballots, it provides transparent and secure elections. Hardware and software are fully open for inspection, ensuring every vote can be trusted.

These projects form an open-source suite of AI infrastructure tools built for modularity, security, and self-hosted deployment, allowing users to maintain full ownership and control of their systems and data. They deliver interoperable AI functions including automation, data retrieval, encryption, and identity management that can be applied across many different industries.

Blockchain specifications define an institutional blockchain system built on distributed custody using Multi-Party Computation (MPC), where no single entity can access or control private keys. All transactions are governed through policy engines, role-based permissions, and full audit logging instead of centralized custody. It supports tokenization and multi-chain interoperability for real-world assets like real estate and financial instruments, with deployment across on-prem, sovereign cloud, and hybrid environments. The result is a secure, auditable infrastructure for programmable assets with built-in compliance and institutional control.
