Beat4key

beat4key is a greek startup which specializes in creating embedded software engineering products, available as soft ips for user secure authentication through heartbeat sound processing (phonocardiogram - pcg). beat4key’s patent pending invention is a hw biosensor module for wearables and smart devices that provides a new biometric authentication solution based on pcg through the sw product cardio®. cardio® takes as input user’s heart sound and processes it to determine if the user is authorized to access the system or to identify a registered user based on machine learning algorithms. user’s biometric signature is kept stored inside the silicon and not in a cloud based server. cardio® is compatible with virtually all processors based on arm architecture and guarantees a simple, powerful and cost-efficient way for secure access to wearables and iot devices. built upon a number of high complexity sound processing algorithms and combined with ble/nfc, cardio® allows for two-factor user a
