Secure Mortgage Application Form Fields
Mortgage applications ask for income, employer, SSN, and bank statements. Every field on a standard form is readable by JavaScript. SmartField encrypts financial data before it exists in the DOM.
What Data This Protects
- SSN
- Income data
- Bank statements
- Employer information
- Property details
Threats Blocked
- Third-party script access
- Analytics capturing financial data
- XSS in mortgage portals
- Session replay recording applications
How It Works
Replace your standard HTML input with SmartField. 2 lines of code:
<script src="https://cdn.smartfield.dev/v1/smartfield.js"></script>
<smart-field type="password" placeholder="password"
encrypt-key="/api/sf-key"></smart-field>
Every keystroke is encrypted with AES-256-GCM. The AES key is wrapped with RSA-2048. Only your server can decrypt.
Why Standard Inputs Fail
A standard <input> stores plaintext in the DOM. Any JavaScript on the page can read it:
document.querySelector('input').value
// "MyBankPassword123" ← stolen
With SmartField, the same code returns:
document.querySelector('smart-field').value
// "eyJ2IjoxLCJpdiI6IkNx..." ← encrypted
Compliance
SmartField helps meet requirements for: TRID, RESPA, GDPR, CCPA
- AES-256-GCM (NIST SP 800-38D)
- RSA-2048 (NIST SP 800-56B)
- Zero-data architecture. SmartField never sees your data.
Frequently Asked Questions
Can this protect mortgage application data?+
Yes. SmartField encrypts every field at the keystroke level. Income, SSN, bank details are never visible in the browser DOM.
Does it work with existing mortgage platforms?+
SmartField is a standard Web Component. It works with any web-based mortgage application system.
What about document upload fields?+
SmartField protects text input fields. Document uploads are handled separately. We recommend combining SmartField for text data with secure file upload for documents.
