Protect Prescription Fields in Healthcare from Session Replay
In healthcare, prescription 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
Prescription entered in a standard form is immediately accessible:
// Session Replay attack:
document.querySelector('input').value
// "Prescription data here" ← stolen
The Fix
<smart-field type="password" encrypt-key="/api/sf-key"
placeholder="prescription"></smart-field>
Now the same attack returns AES-256-GCM encrypted data. The prescription 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 prescription in healthcare?+
SmartField encrypts prescription 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 prescription?+
Not with SmartField. The .value property returns encrypted payloads only. The real prescription 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.
