Proactive browser security: Upload, Form, Link, Paste, Submit, Proof, and Antivirus Protection. Platon Guard is an on-device, proactive browser security extension featuring 7 defense shields designed to protect you from online threats in real-time without sending any of your data to remote servers. 7 PROACTIVE SECURITY SHIELDS: 1. Upload Guard: Analyzes file magic bytes (MZ, ELF, Script headers) and double extensions (.pdf.exe) to block dangerous file uploads and trojan binaries before transmission. 2. Form Guard: Detects and automatically protects sensitive data (Credit Cards via Luhn algorithm, National IDs, IBANs) on unencrypted HTTP forms and suspicious inputs. 3. Link Guard: Zero-latency Bloom filter threat lookup, IDN homoglyph detection, and Levenshtein typosquatting defense to block fake and deceptive phishing domains. 4. Paste Guard: Prevents clipboard hijacking, Clipper malware address swapping, and Base64-obfuscated reverse shell/terminal exfiltration commands. 5. Submit Guard: Pre-flight form validation that scans for hidden input exfiltration parameters and unverified cross-origin submissions. 6. Receipt / Proof: Generates an immutable, cryptographic SHA-256 Merkle chain receipt for every blocked or audited security event using native Web Crypto APIs. 7. Antivirus / Social Engineering: Blocks fake "Win+R / PowerShell" bot verification captcha traps, tech support panic scams, and transparent clickjacking overlays. ZERO-KNOWLEDGE & 100% PRIVATE: • Zero External Requests: All algorithms run locally inside your browser client. • Zero Data Collection: Your browsing history, passwords, and private data never leave your device. • Fast & Lightweight: Built on native Web Crypto APIs and modern Manifest V3 standards. • Tamper-Proof Audit: Export verifiable cryptographic proof receipts directly to JSON. Protect your browsing experience with zero compromise on privacy.
