We have came across many ways of locking and unlocking our phones. At the very first long pressing a key,unlock button followed by star(*) button. Then as the technology grew their came face Unlocking maze and even voice unlocking, but now Blackberry had thrown a massive hit in unlocking the phone,using music rhythm and pattern.
Android and iPhones use the face and voice unlocking, that also gives a good grad of security but their are ways to unlock it easily. For an example while you use a pattern to unlock people may video it and pop out the pattern. Voice could be used without your around a distance of 10feet. Whereas Blackberry's rhythm & pattern is very difficult to broke out.
The thing is that when users tap a pattern on their device to unlock, the device will note the rhythm in which the user types. The pressure given by the user on keys are too used. Thus while some one tries to unlock your phone then.... No way,when they know your phone is enabled with this feature, they wont even try it :)
