REVOCABLE ECG KEY FOR USER AUTHENTICATION

Abstract
In this paper, a novel and simple, revocable approach for generating 128-bit Electrocardiogram (ECG) based biometric key for human authentication system (HAS) is proposed.. The keys have two parts. The first part of the key is a Pseudo-Random Number (PRN) sequence generated by a Multiple Recursive Algorithm (MRA). The second part is revocable and generated on-the-fly. Since considerable portion of the population suffers from various arrhythmias, both normal and abnormal ECG recordings are included for this study. Experimentations are specifically done to study the reliability of the keys for multisession ECG recordings. A BiLSTM network is used for authentication. It is seen that keys generated using the proposed algorithm are extremely robust and therefore, may have a wide range of applications in finance, military, research, and healthcare sectors.
