Always read these statements and make sure they will not do anything strange with your information. But generally, if you trust a company already and you're positive the Web site belongs to that company, you can trust they will not abuse the information you send them. Another concern is transmitting confidential data over the Internet. It is remotely possible that someone could intercept data being transmitted over the Internet and then root out consumer information, including credit card numbers. To prevent this, a consumer should only transmit data over a secure connection.
Most online stores offer users the ability to connect to the store in a secure mode.
This means that all data transmitted to and from the Web site is encrypted. So if data is intercepted somewhere along the line, it cannot be easily read. Those who shouldn't see your data would have to spend a great deal of time and energy trying to decrypt the data, and in all likelihood they would never succeed.
