1 . Our electronic devices today store an awful lot of personal information. We use the devices to read and send e-mails, check bank balances, and even pay our bills over the internet. We want to be assured that if our devices are stolen. our personal information stored inside them will remain safe from the thief who physically possesses the device.

To deal with this problem. Apple has come out with a new iPhone that uses biometric(生物识别的)information to lock itself up. The phone has a fingerprint scanner that will lock or unlock the phone. Your fingerprint becomes the key, and this makes it nearly impossible for others to use your phone without your immediate permission- or does it?

At first look, one would think that this type of security would be welcome in the high-tech community where privacy is valued. Instead, some people are even more worried about their privacy. According to revealed documents, the US National Security Agency is able to slip into smartphones, while the agency can also legally force companies to turn over customers' personal information. If this is true, the fingerprint scanner on your smartphone might become a tool for the authorities to collect your fingerprint data.

Another problem with using biometrics to secure devices is that people don't know how secure the systems actually are. Germany's Chaos Computer Club claimed to have slipped into a biometrically secured iPhone within days of the device's release to the public. If this is the case, people who are using this type of security are much more vulnerable than they are led to believe. Although most security systems are hacked by someone eventually, the speed at which biometric security was hacked was very upset to some.

Regardless of how a device is secured, the debate is still attributes to the trade-off between privacy and security. Governments sometimes need to look at large amounts of information in order to defeat terrorist secret plans, and necessarily, some of the data come from you and me. When we use iPhones and other devices, we lose the ability to safeguard information that we would rather keep private, and we are forced to put trust in others.

It will always be difficult to strike a balance between privacy and security with growing changing technology. Nevertheless, one thing is crystal clear: we all have to sacrifice some of our privacy in order to have security for the public.
