How secure is your Smartphone?

Technology's security is always a problem. Besides the government's track, we are not safe regrading on our personal information. Everything happened online will be recorded and it's hard to find a way to skip the tracking and information steal. As Apple release its new iPad Air, have you ever think that when you check your back account or shopping online, your PIN number will be recorded?

According to the tech news I found today, researchers have found a way to figure out what personal identification number, or PIN, someone is typing into their smart phone by using the device's built-in cameras and microphones to secretly record them.

Our life is becoming so easy with our smartphones, but easy sometimes means dangerous. It handing an increasing amount of sensitive and personal financial information, including banking account, payment apps, online transfers, and other full-featured mobile wallets, such as Apple's passbook. Maybe this convenience create opportunities for cybercriminals.

So what should we do to protect ourself? Security researchers have warned that criminals could use other phone sensors like the accelerometer and gyroscope to puzzle out what someone is typing. Apps or electronic wallets like Trustzone take control of and disable all the available sensors when entering a secure mode. Another suggestion includes randomizing where the numbers appear on the screen.
