Looking for a Freelancer to Develop a Secure and Encrypted Communication System Project Description: I am seeking a professional skilled in cybersecurity and mobile app development to create a highly secure communication system designed to protect communications from any kind of surveillance or espionage. Project Features: Dedicated Mobile Device: Configure a device to use Wi-Fi only, disabling all other features (GPS, 3G/4G/5G modem, cameras, microphone, etc.). Modify the operating system to prevent unauthorized changes to security settings. Custom Communication Application: An app similar to WhatsApp for messaging, file sharing, and calls. Exclusively peer-to-peer communication with no data stored on servers. Advanced end-to-end encryption to secure all exchanged information. Privacy Protection: Use of a secure network (e.g., TOR or equivalent) to obfuscate connections and prevent tracking or localization. Ensuring third parties cannot reconstruct connections or exchanged data. Device-to-Device Connection: Simple connection system (e.g., QR code, authentication keys, or a dynamic username that periodically changes). -Required Skills: Experience in mobile app development (Android or custom operating systems). Advanced knowledge of end-to-end encryption and security technologies. Familiarity with networks like TOR and peer-to-peer systems. Ability to configure and customize hardware devices for specific purposes. -Main Goals: Ensure maximum security and privacy for communications.
