单选题 Questions 53 to 56 are based on the following passage: 　　As more Americans do more things online, Intemet identity theft is a growing--and very costly--problem. Consider the following six aspects and learn the best ways to protect yourself. 　　Guard Your Personal Information. Never respond to requests for personal or account information online (or over the phone). When your social security number is requested as an identifier, ask if you can provide alternate information. Watch out for convincing imitations of banks, card companies, charities and government agencies.Use legitimate sources of contact information to verify requests for information,such as your financial institution’s official website or the telephone number listed on statements. 　　Don’t overshare. Don’t divulge your birth date, mother’s maiden name, pet’s name or any other identifying information on social media websites such as Facebook, LinkedIn or Twitter. 　　Beware of Fake Online Sweepstakes and Contests. All offers that require payment or private information before giving an award are bogus. Take the time to check out the validity of an offer. Ask for contact information from the sender and details about the company running the contest. Once you start asking a lot of questions and make it clear you won’t be pushed to make an immediate decision,most scammers will go away. 　　Ask What Your Bank Is Doing to Protect You. Understand banks’ guarantees for fraud protection: all large providers now offer zero-liability protection for debit and credit cards, while a few offer a guarantee for online banking transactions. 　　Keep a Close Eye on Your Finances. Monitor your bank and credit card accounts weekly. Sign up for alerts to be sent to your mobile phone or email.Monitor your credit and public information online to spot unauthorized activity. Free credit reports from each of the three major credit bureaus are available each year through annualcreditreport.com. Optional fee-based services offer more extensive monitoring of credit information, personal identity records, social security numbers and online transactions. 　　Report It. If you’re a victim of online fraud, contact the authorities. You can file an online report with the Intemet Crime Complaint Center (IC3)--a partnership between the FBI, the National White Collar Crime Center, and the Bureau of Justice Assistance. Also contact your local police to file a report. The more people who report such crimes, the more criminals are arrested.
