Software that encrypts or scrambles the purchase information you send over the Internet will guard the security of your online transactions. Most computers today come with a secure browser already installed. Look for a padlock symbol or similar icon at the bottom of your browser screen, or check with the software manufacturer. Make sure the vendor site is secure. In addition, check the security disclosures of Web sites you visit, along with their privacy policies regarding collecting and using your personal information.
Some disclosures are easier to find than others.
Consider shopping elsewhere. Never give your password to anyone online. This includes your Internet service provider. And, be original when you create your password. Look for the company's physical location.
