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.
