A company called PINoptic has a new method for securing your smart phone that it claims will make it 37 times more secure.
The way the software works is to replace the traditional numbered PIN with a picture based system. The images will show up on each of the 10 numbered buttons; however they will do so randomly. This means that someone watching you will not be able to memorize the sequence but would have to carefully watch the actual images you press.
PINoptics claims that someone would have to watch a person login over 10 times before they would be able to figure out the login.
Smartphones are become more of a target as they often contain personal or work e-mails as well other personal information.
