Viber is a communication platform established in 2010 by Talmon Marco and Igor Magazinnik in Tel Aviv, Israel. It’s currently under the ownership of Rakuten, a Japanese company that purchased it in 2014. The platform offers a variety of features including voice over IP[3] (VoIP), messagerie instantanée[2], group messaging, HD voice, media file sharing, stickers, and video calling. It also provides options for cross-border peer-to-peer payments and business tools suited for small and medium enterprises. Viber has a strong global presence, particularly in Greece, Eastern Europe, Russia, and the Middle East. It’s recognized for its security[4] measures, including end-to-end encryption[1], and has received awards for such.

Définitions des termes
1. ↑ Cryptage de bout en bout ( end-to-end encryption ) End-to-end encryption, often abbreviated as E2EE, is a vital security measure in the digital world. It is a method of secure communication that prevents third-parties from accessing data while it's transferred from one end system to another. In essence, E2EE works by converting the sender's message into code, which can only be decoded by the intended recipient. This guarantees that the information remains confidential as it travels across networks. Despite its benefits, E2EE faces challenges such as vulnerability to man-in-the-middle attacks, endpoint authentication requirements, and issues with regulatory compliance. Backdoors, which can bypass encryption, also pose significant security concerns. This encryption method is widely implemented in various communication platforms and file sharing services for enhanced data security. Regardless of the challenges, E2EE remains a crucial part of maintaining privacy in our increasingly digital world.
2. ↑ messagerie instantanée. Instant Messaging (IM) is a digital communication method that enables real-time transmission of text-based messages over internet or computer networks. Unlike email, IM facilitates immediate, interactive conversation, often enhanced with emojis, file transfers, voice-over IP, and video chat. IM systems can function independently or as part of a larger social media platform. They have evolved significantly since early systems like Talkomatic and CompuServe CB Simulator, developing into graphical user interfaces with a wide range of features. Today's popular services, including Signal, Telegram, WhatsApp, and Snapchat, offer private and group messaging, advanced security measures such as end-to-end encryption, and integration with social networks. They play a vital role in both personal communication and business environments, facilitating effective real-time communication with conversation records for future reference.
