Letter Sealing, a new security system in LINE


Letter Sealing

LINE seems very serious in providing security system for its users. LINE has just provided the latest update for its application on the Android and iOS platforms with a new feature called Letter Sealing.

This is a security feature that implements the encryption method of E2EE or end-to-end encryption, which means, the message you send to friends or family will be encrypted by the system that's attached in each device, not on the centralized server. Thus, it's impossible for third-party application to hack the messages that have been sent.

LINE plans to embed the Letter Sealing feature to the individual conversation and Location Sharing. But LINE ensures that the other features will also follow in the future.

To be able to try this new security system, both of users, the sender and recipient, should have installed this feature, or in other words, they must have been using the latest version of LINE (version 5.3.0) that has been available in Google Play Store and App Store. This feature has to be activated first. 

To enable the Letter Sealing feature: More - Settings - Chats and Voice Calls - and then tap the Letter Sealing.

As information, previously LINE has brought some features to maintain the security of users, such as Hidden Chat, Time Limited, Passcode Lock and also four-digit PIN.
