LINE becomes the first messenger app to introduce the the end-to-end encryption which makes it impossible for the all the top security agencies around the world to intercept any sort of data. Whatsapp and iMessage top two messing apps are still working on this encryption, which is believed to be the next big step for messing apps.

The company makes the announcement on their official blog on Tuesday about its new security feature. This security update will protect LINE users from Hackers and Security agencies who are spying on their citizens in name of state security.

The company named the feature as “Letter Sealing”, which will protect all the LINE messages from any unauthorized access during the delivery time. The security update feature is for Android,  iOS and desktop (including Windows and Mac OS X). Android and iOS users can enjoy this latest security feature only on 5.3.0 and later versions.

Keys associated with encrypted content will be stored only on user’s devices rather than on a central server. That means there’s no key for LINE to hand over as and when law enforcement come knocking. Which has raised many eyebrows among the security agencies in U.S and Europe. Security agencies believe that such encryption will make it easier for the terrorists around the world to communicate and conduct their activities.

On the other hand this has been a big setback for the other messaging apps, because a lot of users will be switch towards LINE after their latest security feature. With the high profile data breaches occurring everyday users are more towards using apps which offers maximum security.

This security update may prove to be the biggest move for LINE in increasing their market share among the messaging apps.
