Why did apple remove touch id from IPhone 11?

  We all know that apple is the one of the prominent companies that manufactures highly secured smart phones in the planet. Apple devices are built with an high quality material and it as a good software optimization. People tend to buy an iPhone because of its security and unique design. Everytime apple launches a new product they implement a new technology into their device and they are mimiced by other smartphone manufacturers. But recently when apple launced iphone 11 they had removed touch id on their devices is it an upgrade or a downgrade.

     Our smartphone may have several type of security features like pattern, passcode, alpbetical password etc., But the fingerprint lock is considered as the safest lock in the world as each and everyone of our fingerprints are unique from one another. This is the reason why every smartphone manufacturer came with the stratergy of embedding fingerprint scanner on their smartphone. But fingerprint encryption being one of the most safest way of encryption why did apple remove this safety feature from Iphone 11.

          Before going to this topic lets see how a fingerprint scanner works in our device.

         Every device having a fingerprint encryption has a fingerprint print scanner. When we register our fingerprint in a device. The scanned fingerprint data is converted into a numerical template. This data records the pattern of ridges and valleys of your fingerprint has each and everyone of our fingerprints have a different pattern. You can look into the image where black prints are called as ridges and white one's are called as valleys. When you try to unlock your device with your fingerprint it compares with the registered fingerprint if it matches the device gets unlocked.

   There are different categories of fingerprint check in the below image to see which category your finger print belongs to.

     Now you would have unterstood the concept of fingerprint lock. Our fingerprint being one of the most complicated one it may seem like its very hard to decrypt a fingerprint lock.  

      But it has a vulnerability an hacker can decrypt your device by injecting a malware into your device and get the data of the recorded pattern of your fingerprint or he can also clone the fingerprint from a photo where your hand is visible in the image. This can be done by tracing the ridges over your fingerprint and imprinting the traced fingerprint on a synthetic sheet and use this as an implant to bypass the fingerprint scanner.

     There was a german hacker named starbug who used this technique to clone the finger print of the german defence minister using a public photograph.

    Now you may come to know how vulnerable your fingerprint encryption could be where as in a country like india a person's Information from his name, date of birth, retinal scan and all his/her details are hidden in the finger print as every individual has enrolled to aadhaar and all the information stored in his/her Aadhaar and using this vulnerability a person can steal someone's identity.

      My intention was not to discuss about iPhone security, i wanted to share with you about how vulnerable a fingerprint encryption can be.
