Security of data is of significant concern to Internet users, especially concerning personal information. Princeton Online is a member of Verisign's Secure Site Program. This program allows users to learn more about web sites they visit before they submit any confidential information. Once a user verify's the certificate is accurate, they may submit sensitive data (e.g., credit card numbers) to the site with the assurance that:
- The site has a VeriSign Secure Server ID.
- VeriSign has verified the organizational name and that PRINCETON ONLINE, INC. has the proof of right to use it.
- The site legitimately runs under the auspices of PRINCETON ONLINE, INC..
All information sent to the site, if in an SSL session, is encrypted, protecting against disclosure to third parties.
