Electrocardiogram (ECG) signals varying from person to person, it could possibly be applied as a tool for biometric recognition. This paper attempts to introduce an individual feature of ECG with a chaotic Henon map for cryptography. The encryption system utilizes a portable instrument (Heart Pal) to collect ECG signals from the encrypted person and applies an intelligent algorithm based on Chaos theory to generate initial keys for chaotic Henon map. High quality randomness of ECG signals results in a widely expanded key space which would be an ideal key generator for data encryption.
