Biometric-based medical watermarking system for verifying privacy and source authentication

Abstract EN

Two important requirements in the e-health care system are ensuring the authenticity of the source from which data is received and preserving the privacy of patients’ medical record.

Medical records must only be accessed and modified by the authentic source.

Any modification of medical records may lead to misdiagnosis and consequently, negatively affect the life of the patient.

So, the privacy of medical record and the authenticity of the sender source must be satisfied.

This research focused on a watermarking technique’s ability to satisfy the above requirements.

A watermarking system based on biometrics is presented in which the sender’s iris code is programmed as a key for sender authentication.

In addition, patient record privacy and the iris code is preserved by encrypting it using the chaotic encryption method.

Experimental results showed that the proposed system satisfied the two security requirements
