Yes, Signal video calls are designed to be safe and secure.
Signal prioritizes privacy and security, employing end-to-end encryption for all communications, including video calls. This means that only you and the person you're communicating with can access the content of the call. Signal is designed to never collect or store any sensitive information, therefore "Signal messages and calls cannot be accessed by us or other third parties because they are always end-to-end encrypted, private, and secure."
Why Signal Video Calls Are Considered Safe:
- End-to-End Encryption: This ensures that your video calls are encrypted from your device to the recipient's device, preventing eavesdropping.
- Privacy-Focused Design: Signal is built to minimize data collection and maximize user privacy.
- Open-Source Protocol: The Signal Protocol is open-source, allowing independent security experts to review and verify its security.
- No Data Retention: Signal does not store your call history or video call content on its servers.
How End-to-End Encryption Works:
End-to-end encryption involves:
- Encryption Keys: Generating unique encryption keys on your device and the recipient's device.
- Secure Exchange: Securely exchanging these keys between the devices.
- Data Encryption: Encrypting the video and audio data using these keys before transmitting it over the internet.
- Decryption: Only the recipient's device can decrypt the data using their unique key.
