Deep dives
The Power of Signal's Encryption
Signal offers superior privacy compared to other messaging services like WhatsApp and Telegram. While WhatsApp uses Signal's encryption technology for the content of messages, it still collects extensive metadata, which includes information about users' contacts, locations, and usage patterns. This metadata can reveal intimate details and is a significant privacy concern since it can be exploited by various actors, including state agencies. In contrast, Signal's architecture is designed to collect as little data as possible, ensuring that users' private communications remain truly secure.
