A New Artificial Neural Network Framework for Gait-Based Biometrics

Researchers at Imperial College London have recently devised a biometric cryptosystem approach for securing the wireless communications of wearable and implantable medical devices. Researchers at Imperial College London in the U.K. have developed an approach for securing wireless communications of wearable and implantable medical devices. Their biometric cryptosystem (BCS) framework uses an artificial neural network (ANN) and gait signal energy variations to analyze the way in which different people walk. The researchers used the ANN to extract features from body sensor networks, generating binary keys on demand, without requiring the user's intervention. The team tested the approach on a gait dataset, and found the binary keys generated had high entropy for all subjects.
