Top officials from the Trump administration recently found themselves at the center of a controversy when they inadvertently included a journalist in a Signal group chat meant for sharing sensitive war plans. This incident has prompted Democratic lawmakers to call for a congressional investigation into the potential security breach. Mismanagement of classified information can be a criminal offense under U.S. law, although it’s still uncertain whether such laws were violated in this instance.
Signal: A Secure Messaging App
Signal is renowned for its robust security features, utilizing end-to-end encryption. This ensures that private conversations and calls can’t be accessed by the service provider, thereby guaranteeing user privacy. Available on both smartphones and computers, Signal allows for secure messaging, voice, and video calls. Users need a phone number to register, but unlike other messaging apps, Signal does not track or store user data. Its open-source code is publicly available, allowing security experts to verify its safety.
Security Features of Signal
Signal prides itself on being a fully encrypted, open-source messaging service that avoids storing substantial user data. The only information retained on its servers includes phone numbers, the date of user registration, and the last login time. All other data, such as contacts and chats, are stored locally on the user’s device, with an option to auto-delete messages after a set period. Signal’s commitment to privacy extends to having no ads or affiliate marketers, and it provides features to enhance user anonymity, such as hiding phone numbers.
Development and Leadership
Founded in 2012 by Moxie Marlinspike, Signal is currently headed by President Meredith Whittaker. In 2018, Marlinspike and WhatsApp co-founder Brian Acton established the Signal Foundation, a non-profit organization that now oversees the app. Acton, who departed WhatsApp over disagreements about data usage and advertising, contributed $50 million to initial funding. Signal remains independent and unaffiliated with major tech companies.
