The security of a mobile device is a great concern nowadays. Different types of security layers are used to protect the device or its application. The revolution is very rapid as the data security has become the most valuable asset nowadays. We store a lot of valuable element inside a mobile phone device such as bank a/c, credit card, e-card, online transactions, resources and so on. So to protect these data from leaking or being used by other parties we must give the protection of those devices. Here, we are going to talk about four different types of security protocols. So without any further delay let’s begin.

Previously we had pass codes, PINs, Patterns and combinational numbers to lock or unlock any security protocols. But these systems became very time consuming and memorizing the pattern or characters are also a challenging stuff. So engineers came up with a solution where it takes less time to unlock/lock a device with more precision.

  1. Capacitive Finger Print sensor or Touch ID: This type of system works with a dedicated capacitive panel which can measure the capacitance when touching the panel and store the perspective values of finger print routes in a very efficient way. But every system has some flaws. Here some of the advantages and disadvantages of the capacitive finger print are given below: The finger print pattern is very unique parameter in case of security issues. So without the owner it is nearly impossible to breach the security. But it can be bypassed by copying a dummy of a finger with the same pattern and it is possible in some cases when the sensor is not that cutting edge.
  2. Face recognition or FaceID: In current days face recognition technology is one of the most used and reliable technology used by many brands such as Apple, Samsung, Sony, Xiaomi, Nokia, and Motorola and so on. It has multiple scopes of operation, such as: some uses the in-built front camera to determine the pattern image and other uses laser technology to sketch the 3D image of the face. In this case the devices which use camera to capture the image can’t operate in some case such as at night or low light. And some days ago, there were also an issue like the Twin. When iPhone X first launched, the same type of issue occurred, some were pretending that it can be unlocked by both the twin and it is un-expected. However, Apple Inc. took the matter seriously and changed the pattern matching algorithm and solved the issue in next software update.
  3. Under screen fingerprint sensor(Optical Sensor): There are many brands like One Plus, Oppo and vivo has this type of unlocking feature. These devices works with a sensor installed under the display of those devices. Usually there is photoelectric sensor installed under the display and take the reading surprisingly with high precision and serves its purpose.
  4. Retina scanner: Now we’ve entered the big buddy gang.Retina is considered as one of the top most secure method in case of security. The retina scanner takes the retina pattern of human eye and stores it in a very unique way and matches the pattern every time when someone places in front of eye. Samsung installed it first, but there were some health issue, later on, they upgraded the (InfraRed)IR technology to optimize with the human eye.


Conclusion: So far, what we’ve known is Retina scanner is one of the most advance and secure medium of pattern. But other systems are also considered as the secure enough to be cracked.
