It includes such data as time, sender, receiver, contact list, device ID, and so on. Most messaging apps store message metadata by default. It is used to identify users and their credentials. Metadata is one of the most problematic elements of user privacy.For example, Signal has a timeout option that automatically deletes messages after a certain period upon the message is read. So actually giving users the power to erase their messages completely is an excellent step towards building a trustworthy relationship with the users. Facebook is doing it all the time Google does it, Yahoo probably remembers what you did in your past life. These messages may remain on the service provider’s servers. Users can delete messages on their device, but not from the other user’s conversation or server log. While message deletion is one of the basic features of every messenger, secure or not, there is a caveat. Message deletion is another critical piece of the puzzle.It is used to guarantee user privacy and data security by scrambling messages and making them unreadable without the encryption keys. Encryption is the most prominent selling point of the encrypted messaging app.The value proposition of the encrypted messaging app is built upon four basic principles: Now let’s look at some of the major secure messaging apps and their business revenue models. What is secure messenger’s value proposition?

Unless the perpetrator can find a way of retrieving a private key from the user’s device (it is possible, sim swap and losing a phone helps) - the intercepted data is as good as the cat’s full body typing documents. It is so complex, brute force methods of deciphering are no good for it - too hard to match a key with long strings of various randomly generated characters (there are way too many possible combinations). No one can read it without the private key. The data stored on the server is no use in its encrypted form - it is just some letters and numbers beyond comprehension (unless you’re into conceptual writing). The reason why end-to-end encryption works is its sheer impenetrability. The message is then sent to the user via server and decrypted with the private key.
Secure messengers evolved into a distinct category due to the growing awareness that communication over the internet is accessible by third parties and reasonable concerns that the messages can be used against the users.
While every modern messenger system is using different security practices (most prominently SSL/HTTPS) - the difference between secure and classic messengers is that we don’t know in the scope of implementation and the approach to user data. Secure private messenger is a messaging application that emphasizes privacy and confidentiality of users using encryption and service transparency. What are secure messengers apps like Signal and Wire? In this article, we will talk about secure messengers, why they matter and also discuss the ways they generate revenue.
