Private Communication Engine
The Private Communication Engine is the core of SECR. It ensures that all communication stays encrypted, anonymous, and under the user’s full control. Messages, calls, files, and groups are protected at every layer, from device storage to network routing.
1. End-to-End Encryption
Every message, call, and media file uses end-to-end encryption. Only the sender and receiver can decrypt the content. SECR servers never have access to:
• message text • call data • attachments • encryption keys
Communication remains private even during server compromise or network interception.
2. Decentralized Identity Keys
The communication engine relies on device-generated identity keys. They are never uploaded, synced, or stored centrally.
This design removes the single point of failure found in traditional messaging platforms. If a device is wiped, SECR cannot restore identity keys or message history, ensuring communication stays decentralized and user-owned.
3. Metadata-Minimized Protocol
SECR’s protocol reduces metadata leakage by avoiding:
• phone numbers • contact syncing • cloud backups • central user directories • location- or IP-based pairing
Only the minimum information required to deliver encrypted packets is processed. Servers never learn who is messaging whom.
4. Hidden and PIN-Locked Chats
Users can secure sensitive conversations with additional protection layers:
• Hidden chats stay invisible until unlocked • Chat PINs restrict access to specific threads or groups • Destruct PIN instantly wipes all local communication data
This protects against device seizure, forced access, or casual snooping.
5. One-Time Chat Links
SECR allows users to send encrypted messages to people who don’t have the app. A temporary, one-time link delivers the message and then self-destructs.
The viewer never needs to install SECR, and the link expires automatically, removing any long-term data exposure.
6. Media Privacy Tools
All photos, videos, and documents pass through SECR’s privacy filter:
• EXIF metadata is removed or obfuscated • GPS coordinates and device details are scrubbed • File previews are encrypted end-to-end • Downloads stay inside encrypted storage
This prevents leaks of location, timestamps, or camera signatures.
7. Group Communication
SECR supports encrypted group chats with:
• PIN locks • hidden groups • local-only storage • no server-side membership logs
Group membership and conversation history exist only on user devices.
The Private Communication Engine ensures that communication inside SECR remains secure, decentralized, and resistant to surveillance or data extraction, even in hostile environments.
