Protect Medical History Fields in Insurance from Session Replay
In insurance, medical history is one of the most targeted data types. Standard HTML inputs expose it to session replay attacks. SmartField encrypts it at the keystroke level.
The Risk
Medical History entered in a standard form is immediately accessible:
// Session Replay attack:
document.querySelector('input').value
// "Medical History data here" ← stolen
The Fix
<smart-field type="password" encrypt-key="/api/sf-key"
placeholder="medical history"></smart-field>
Now the same attack returns AES-256-GCM encrypted data. The medical history never exists as plaintext in the browser.
What the Attacker Gets
document.querySelector('smart-field').value
// "eyJ2IjoxLCJpdiI6IkNxT3..." ← 600+ chars of encrypted gibberish
Useless without your server's RSA-2048 private key.
Compliance
SmartField uses NIST-approved algorithms: AES-256-GCM (SP 800-38D) and RSA-2048 (SP 800-56B). Compatible with PCI-DSS, HIPAA, GDPR, SOX, and FISMA requirements.
Frequently Asked Questions
How does SmartField protect medical history in insurance?+
SmartField encrypts medical history at the keystroke level using AES-256-GCM. The data never exists as plaintext in the browser DOM. Session Replay Protection is achieved through 13 independent security layers including closed Shadow DOM and WeakMap isolation.
Can session replay attacks steal medical history?+
Not with SmartField. The .value property returns encrypted payloads only. The real medical history is stored in a WeakMap inside a closed Shadow DOM, invisible to any JavaScript including session replay attacks.
How do I implement this?+
Replace your standard input with smart-field. 2 lines of HTML. Install the server SDK (Node.js, Python, Java, Go, PHP, or Ruby) to decrypt on your backend.
