End-to-end encryption
End-to-end encryption ensures that a message is turned into a secret message by its original sender, and decoded only by its final recipient. Other forms of encryption may depend on encryption 
performed by third-parties. That means that those parties have to be trusted with the original data . End-to-end encryption is generally regarded as safer, because it reduces the number of parties who might be able to interfere or break the encryption.
