How can I tell whether my browser has adequate security for exchanging private information via the Web?
Your browser should support 128-bit encryption (security programming). For two common browsers, follow these instructions to find out the level of encryption for your browser:

Internet Explorer 7.0:

At the top of the browser window, navigate to Help > About Internet Explorer. Check the Cipher Strength setting. It should say 128-bit or higher.

Firefox:

While connected to this site, double-click the padlock icon in the bottom right corner. In the pop-up that appears, verify that you're using high-grade encryption.

How can I obtain a browser with 128-bit encryption technology?

Contact your internet service provider (ISP), such as AOL, or visit the web site of the company that makes your favorite browser. We recommend Internet Explorer. Upgrades are usually free to download.

How can I tell if my connection to this site is secure?

Once you log on to this site, you will see on certain pages a security icon or symbol (for example, a padlock) in the lower right-hand side of your screen. This symbol generally appears on pages from which we collect sensitive information. If the symbol is there, it means that data you submit on that page is encrypted. Encrypting data helps us to stop unauthorized third parties from accessing your data while it is being transferred to Healthx.
