Google has begun rolling out end-to-end encryption for Wealthy Communication Service, the text-messaging normal the trade large is pushing as an alternative choice to SMS.

Abbreviated as RCS, Wealthy Communication Service offers a, effectively, richer consumer expertise than the traditional SMS normal. Typing indicators, presence data, location sharing, longer messages, and higher media help are key promoting factors. They result in issues like better-quality photographs and movies, chat over Wi-Fi, realizing when a message is learn, sharing reactions, and higher capabilities for group chats.

The rollout will proceed into subsequent yr.

In 2016, Google launched its Allo messaging app. It, too, provided E2EE, however solely when customers dug right into a settings menu and turned it on. Two years later, Google killed it. This time with RCS, Google mentioned, “eligible conversations will routinely improve to be end-to-end encrypted.”
