Protect Insurance ID Fields in Healthcare from Session Replay

In healthcare, insurance id 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

Insurance ID entered in a standard form is immediately accessible:

// Session Replay attack: document.querySelector('input').value // "Insurance ID data here" ← stolen

The Fix

<smart-field type="password" encrypt-key="/api/sf-key" placeholder="insurance id"></smart-field>

Now the same attack returns AES-256-GCM encrypted data. The insurance id 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 insurance id in healthcare?+
SmartField encrypts insurance id 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 insurance id?+
Not with SmartField. The .value property returns encrypted payloads only. The real insurance id 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.
