Users of RCS chats don't have to worry about privacy. All photos, audio and text messages are securely protected by end-to-end encryption. Not only outsiders cannot read them, but also the operator through whom the message is sent, and even the developer of the messenger. In addition, Google is constantly working on security protocols, so the protection of RCS chats is on top.

Features of end-to-end encryption technology

End-to-end encryption (E2EE) is a data encryption technology in which, during sending, information is encoded on the source device, turning into an incomprehensible set of characters. It can only be decoded on a smartphone that has the recipient's SIM card inserted into it.

A special key code is used in decryption, which has the following features:

• The same key appears on the recipient's and sender's phones, and it is located only there.
• A new key is created for each message. It is deleted from the sender's device immediately after sending the message, and from the subscriber's phone after receiving it.
• The key is not transmitted to Google or any other servers, and it cannot be intercepted. Even if hackers can get to the operator's databases, the message cannot be decrypted without a key.

This protection of RCS chats allows you to be sure that the message will be decrypted only if the keys of the sender and recipient match. This will confirm that the message has reached the recipient, and the content will appear.

Privacy in group chats

Among the few claims that have previously been made to RCS chats protection is the lack of E2EE in group channels. But in 2023, Google solved this problem by implementing automatic encryption in all collective chats with an RCS connection.

This means that the information shared in the group is now securely protected, unless its members send screenshots to someone or show the message to an outsider.

How to find out if RCS chat protection is installed

It is easy to understand whether end-to-end encryption is enabled in RCS chat. If you see a lock on the button you are using to send a message when writing a text or uploading a media file, the protection is enabled.

How to connect an RCS chat for mass mailing

RCS chats are a great option for business if you want to reach as many subscribers as possible, especially those who do not use popular messengers. Decision Telecom is an operator that will provide fast and secure delivery of text and media messages anywhere in the world at an affordable price.
