Aura
Acoustic-Based key exchange
Exchanges encryption keys using sound samples rather than digital transmission, eliminating metadata exposure.
Real-World Decryption Trigger
Messages remain encrypted until a matching sound is detected by the device's microphone, activating decryption locally.
Invisible, Low-Exposure Security
Messages are transmitted briefly through the cloud, but decryption is only triggered locally by detecting the correct acoustic signal. Aura minimizes exposure while enabling stealth communication. Even in offline or low-connectivity environments.
Stealth By Design
No visible keys, links, or prompts -- decryption is only possible when the correct real-world sound is detected, making Aura Ideal for covert or sensitive operations.
Adaptive Use Cases
Whether embedded in secure apps, used in field ops, or integrated into enterprise systems, Aura adapts to environments where silence, secrecy, or real-world triggers are essential.
