To further protect your privacy, you can use certificates to verify your identity and protect important information, such as your credit card number, on the Internet. A certificate is a statement verifying the identity of a person or the security of a web site. You can obtain your personal security certification from an independent Certification Authority (CA). A personal certificate verifies your identity to a secure web site that requires a certificate, while a web site certificate verifies its security to you before you send it information. When you visit a secure web site (one whose address may start with " https " instead of "http"), the site automatically sends you its certificate, and Internet Explorer displays a lock icon on the status bar.
