With the recent Cambridge Analytica news about online data breaches of Facebook and other companies, it has become imperative that you use only secure apps. To send and receive voice and video messages, use only encrypted messaging applications.
From telecom companies to hackers, criminals and advertisers to governments, everybody is in the pursuit of data mining. All our sensitive data is at risk and could be misused if it falls in the wrong hands. Our lives are now so entangled with the Internet that we cannot imagine forgoing digital apps. In such a situation, it is only fair that you started looking for the most effective encrypted messengers to make communications. Here we give you a simplified guide of the best-encrypted apps. But first, let us see why end-to-end encryption is important.
Encryption is the process of coding and decoding a message or text using a cryptographic system. This has been in use for a long time to transfer confidential data. However, end-to-end encryption adds an extra layer of protection to traditional encryption.
An encrypted message is nothing but a cipher of the original message, which can be deciphered when the recipient gets it. Here, the code to cipher and decipher is the same and is known only to the sender and the recipient. However, the glitch is that this common code may be known to a third person, who could unlock the message and use it as he wills. This is where end-to-end encryption wins.
Here, the sender has a public key that belongs to the recipient. He encrypts the message with the public key and sends it to the recipient. The recipient, on the other hand, has a private key that is unique to him. With this, he can decrypt the message he receives.
How End-to-end Encryption Matters
End-to-end encryption provides an additional layer of security as it makes the communication unreadable to the third party. The advantage with this is that even if someone gets hold of the encrypted communication, there is no way it can be decrypted without a private key.
Hence, when you communicate via an app on two or more devices, the encrypted information will be in the form of a secret code. So, spying agencies, ISPs, the app developer or even governments are kept away from your private data. This is because the message is not in plain text; the data is not at risk of being tampered with and you can be surveillance-free.
In the case of encryption in transit, there is a chance of a hacking attack at the end of the service provider. There is also a serious possibility of a compromise or corruption by an insider. For any reason, there could be data breaches and information might be leaked. Rather than having the communication encrypted by the service provider, end-to-end encryption is done at the sender’s end and recipient’s end. The public key is viewable by all and is stored on the server, whereas the private key remains with the recipient and is stored locally.
