We investigated technological trends in an electrocardiogram (ECG)-based biometric cryptosystem that uses physiological features of ECG signals to provide personally identifiable cryptographic key generation and authentication services. The following technical details of the cryptosystem were investigated and analyzed: preprocessing of ECG signals, extraction of personally identifiable features, generation of quantified encryption keys from ECG signals, reproduction of ECG encryption keys under time-varying noise, and new security applications based on ECG signals. The cryptosystem can be used as a security technology to protect users from hacking, information leakage, and malfunctioning attacks in wearable/implantable medical devices, wireless body area networks, and mobile healthcare services.

네트워크 기반 서비스를 이용하여 심전도 신호를 전송하는 과정에서 심전도의 특징 값을 조합한 one-time 템플릿 기반의 암호키를 생성하고 또한 이를 이용하여 심전도 신호를 암호화 하고자 하였다. 결과적으로 심전도 신호의 암호화/복호화 과정을 통하여 환자의 정보를 보호할 수 있는 생체 신호의 송수신 보안을 구현하고자 하였다.
