What is smartphone encryption?
Smartphone encryption is process of making your smartphone secure, and protecting its data and information from any unauthorized access.
To enhance mobile security there are two main kinds of encryption that a smartphone can have to prevent unauthorized access to private information – one is aimed at securing the 'data at rest', and second secures the 'data in motion'.
To secure 'data at rest' usually smartphone device is encrypted. An encrypted smartphone typically has a key or a passphrase to allow access to the phone, protecting information stored on the mobile device – photos, text messages, email communication, call information, access to social profiles and private data, documents, etc.
When a device is encrypted it stores the information in an unreadable scrambled format. The information is unlocked only with an authorized key with the device owner. Typically a smartphone key is an alphanumeric passcode or a passphrase comprising of a combination of letters, numbers and/or special symbols. Some high-end and latest smartphones models also use fingerprint authentication to unlock the encrypted device.
To secure the 'data in motion' just having the mobile device encrypted is not enough, the information transferred from one device to another (communication) can be secured through a process called as end-to-end encryption. End-to-end encryption ensures that data or information is accessible and readable only to the person it is intended for. Data is encrypted from the device when it is sent and decrypted only on the authorized recipient's device. No third parties in middle, communication carriers, unauthorized persons, or agencies will be able to access to the information.
How important is smartphone encryption?
There is an old proverb which says, “a man's home is his castle”, but in today's age it would not be wrong to say, “a man's smartphone is his castle”! A smartphone is the closest thing a person can have in today's world, and it remains with you all the time like your shadow. It is rightly said that a smartphone is even closer to you than your best friend since your smartphone has more information about you than your best friend can ever have. On your smartphone there is a list of your contacts, your call records, your private messages and conversations with your friends, family and colleagues, your banking and financial information, your passwords, private and personal photos, videos, business documents, etc. Protecting this information and preventing it from falling into wrong hands is crucial, and the only way to that is through encryption.
