Knock Code: LG's unlock method better than Apple's and Samsung's fingerprint scanners

LG wants to present to consumers their own way of locking a device which is rather special and would be classified as user-friendly and safe.

The unlock method is called Knock Code and is here to replace all other ways of unlocking a device, from the simplest such as pin to the most special as fingerprint unlock.

Knock Code, as one realizes from its name, is based on "knocking" with the finger on the screen of a locked phone to unlock it. Each user has the ability to tap anywhere on the screen a personal, unique combination of taps, activating and unlocking the device with ease even with one hand.

LG decided to work innovatively for the user by offering the ability of safe storage of personal data, as well as ease of access. The Knock Code may consist of 2 to 8 taps, creating over 80,000 possible combinations. From the plethora of combinations, the user can create combinations that are quite simple to very complex. All you need to do is envision a 2x2 grid on the screen, tap in your selected Knock Code, and you’ll be taken directly to your home screen, saving the extra step of unlocking it while using Knock On.

Other companies, such as Apple with the iPhone 5S and Samsung with the Samsung Galaxy S5 use fingerprint scanners on their flagships. However, recent researches indicate that 20% of users using Fingerprint Scanner are not satisfied with the efficiency of the detector and have to repeat the process since the scanners are affected by external factors such as temperature or dust. Biometric technology used by companies today is not able to distinguish a real from a artificial fingerprint.

In addition, the use of password to unlock the screen can be easily visible by a stranger.

As a result, Knock Code is the solution to all these problems while being easy to use, fast, free from the need for a specific position of the user during the introduction of the code. This solution needs no expensive equipment. LG already incorporates the Knock Code in the new L Series III and will soon be available for most smartphones through upgrades including the series G, thus converting the safety of the smartphone an affordable luxury for most users.
