A new feature called 'Letter Sealing' will allow Line messaging users to send totally encrypted text messages, safe from the eyes of anyone but their intended recipient.
The key to decoding the encrypted texts will be stored on the user's smartphone, rather than on the Line messaging server, meaning that letter-sealed texts won't even be accessible to Line messaging itself. Texts sent through the encryption feature will be truly and completely private.
Most of Line messaging's users are based in Asian countries, where concern about communication surveillance is wholly justified. The governments of Thailand and India, for example, have passed laws allowing them to read their citizens' private text messages. The new letter sealing feature in Line messaging will help texters keep their personal messages hidden from unwanted readers.
