Abstract EN
Healthcare institutions adapt cloud based archiving of medical images and patient records to share them efficiently.
Controlled access to these records and authentication of images must be enforced to mitigate fraudulent activities and medical errors.
This paper presents a zero-watermarking scheme implemented in the composite Contourlet Transform (CT)—Singular Value Decomposition (SVD) domain for unambiguous authentication of medical images.
Further, a framework is proposed for accessing patient records based on the watermarking scheme.
The patient identification details and a link to patient data encoded into a Quick Response (QR) code serves as the watermark.
In the proposed scheme, the medical image is not subjected to degradations due to watermarking.
Patient authentication and authorized access to patient data are realized on combining a Secret Share with the Master Share constructed from invariant features of the medical image.
The Hu’s invariant image moments are exploited in creating the Master Share.
The proposed system is evaluated with Checkmark software and is found to be robust to both geometric and non geometric attacks.
