Telecom: Empowering Connectivity and Communication​

Secure Messaging and Calling App Connecting Globally

Viber is a popular messaging and calling application that allows users to connect with friends, family, and colleagues across the globe. Launched in 2010, Viber quickly gained popularity as a free and convenient communication platform.

What is Viber?

Viber offers a wide range of features, including text messaging, voice and video calls, group chats, multimedia sharing, and even the ability to make international calls to non-Viber users at low rates. With its user-friendly interface and broad compatibility across various devices and operating systems, Viber has attracted millions of users worldwide.

Key Features of Viber

There are two key aspects that makes Viber a great tool: open-source software and its privacy and security functions.

Open-Source Software

Open-source software refers to software that is freely accessible, allowing users to view, modify, and distribute its source code. By leveraging open-source software, Viber benefits from the collaborative efforts of a global community of developers, ensuring a robust and reliable platform.

Viber incorporates open-source components in various aspects of its application. For instance, it may use open-source libraries or frameworks for certain functionalities such as encryption, audio/video codecs, networking protocols, or user interface elements. These open-source components contribute to the overall performance, security, and user experience of the Viber application.

Open-source software not only provides Viber with a solid foundation but also fosters innovation and allows for continuous improvement. The open nature of the software encourages developers to contribute enhancements, bug fixes, and new features, which can ultimately benefit Viber users.

While Viber does utilize open-source software, it’s important to note that the application itself is not open-source. The Viber application itself is developed and maintained by Viber Media, a company owned by Rakuten Inc.

However, by incorporating open-source components, Viber demonstrates its commitment to leveraging the collaborative efforts of the open-source community to deliver a high-quality communication platform.

Privacy and Security

One of the key features that sets Viber apart from other messaging apps is its emphasis on privacy and security.

Viber employs end-to-end encryptions for all messages, voice calls, and video calls. This level of security has made Viber a popular choice among users who value their privacy.

Here are some key aspects of Viber’s security and privacy measures:

  • End-to-End Encryption: Viber applies end-to-end encryption to all messages, voice calls, and video calls, ensuring that only the intended recipients can access the content. This means that Viber itself cannot access or decipher the encrypted communications.
  • Hidden Chats: Viber offers a “Hidden Chats” feature, allowing users to hide specific conversations behind a PIN or fingerprint lock. This adds an extra layer of protection for sensitive conversations.
  • Self-Destructing Messages: Viber enables users to set self-destruct timers for their messages, ensuring that they automatically disappear after a specified period of time.
  • Secure Contacts Authentication: Viber utilizes a secure contacts authentication process to verify the identity of contacts in your address book. This helps prevent impersonation and ensures that you are communicating with the intended individuals.
  • Trusted Contacts: Viber allows users to designate certain contacts as “Trusted Contacts.” When a trusted contact changes their Viber account or device, both parties receive a notification, providing an added layer of security against unauthorized access.
  • Public Account Verification: Viber offers a verification process for public accounts, ensuring that users can trust the authenticity of official accounts representing public figures, brands, or organizations.
  • Block and Report: Viber provides users with the ability to block and report unwanted contacts or suspicious activity, allowing for greater control over who can interact with them on the platform.

It’s worth noting that while Viber takes measures to prioritize security and privacy, it is important for users to also practice good digital hygiene, such as setting strong passwords, regularly updating the app, and being cautious about sharing personal information.

Additional Features

Flexible Communication

In addition to its core messaging and calling functionalities, Viber offers several supplementary features that enhance the user experience. For instance, users can create public accounts or communities where they can share news, updates, and content with their followers. Viber also provides a range of stickers, GIFs, and emojis to add fun and creativity to conversations.

Viber Out

Viber Out is another notable feature of the app. It allows users to make calls to mobile or landline numbers outside of the Viber network. By purchasing Viber Out credits, users can connect with people who are not on Viber at affordable rates. This feature has made Viber a convenient option for international communication.

Desktop Application

Furthermore, Viber offers a desktop application that syncs with the user’s mobile device. This allows for seamless messaging and calling across multiple platforms, providing flexibility and convenience.

Integrated Services

The app has also integrated additional services and features over time. For instance, Viber includes a Discover feature that offers various content and services such as news, games, and shopping. This expands the app’s functionality beyond just communication, providing users with a more comprehensive experience.

Viber has evolved into an intricate communication platform that offers solutions to the various needs of its users. Whether it’s staying in touch with loved ones, conducting business calls, or exploring engaging content, Viber offers a range of tools to enhance communication and connectivity.

Viber stands outs as a versatile and feature-rich messaging and calling application that has gained popularity worldwide. The app’s commitment to user privacy is further reinforced by secure contacts authentication and trusted contacts features.

Additionally, Viber’s block and report functionality empowers users to maintain control over their communication experience.

Beyond its robust security and privacy features, Viber offers a range of tools for seamless and enjoyable communication, including multimedia sharing, public accounts, stickers, and international calling capabilities through Viber Out. Whether connecting with friends, family, or business contacts, Viber provides a reliable platform that keeps users connected globally.

Viber has cemented its position as a reliable and user-friendly communication tool by consistently evolving and catering to user demands.
