TightBeam Communicator is a free, secure texting app. Creating a secure contact is done in-person using QR codes and your iPhones camera, ensuring that no one can intercept the connection. Once connected, messages can be sent between two connected devices that are unreadable by anyone but you and your contact. Not even the developers of this software know how to read your private messages!
TightBeam uses QR codes to transmit a secure key from one device to another. This is done to prevent a Man-in-the-Middle attack. This method of connecting ensures the person you connected with is the person you think it is (because they are standing right in front of you!).
This application is intended for use by government, military, law-enforcement, political figures, and anyone who wants to ensure a private line of communication.
Features:
• End-To-End Encryption
• Optionally auto-delete Messages
• Face-to-Face trust
• Highly resistant to Man-in-the-Middle attacks
• No centralized message repository
• No centralized certificate authority
• Connections are not established over wifi, cellular, or bluetooth, preventing eavesdropping.
TightBeam is ad funded with iAd rather than with a subscription or purchase to make it as accessible to as many people as possible.
