| Popis | Medical institutions adapt digital based archiving of patients records images to fulfil its advantages like availability, easy sharing, high resolution etc. Digital form of records brings apart from advantages also disadvantages at security risks. It is easier attacking, stealing, using without authorization etc. This article deals with this security issue. It names methods of medical image watermarking and compares their plus and cons. Concept of Zero-reversible watermarking, that combine advantages of described methods, is proposed. Four purpose of this concept, there are examined and statistically compared attributes of medical images in a huge database (60 000 images) of medical records from various field and modalities like resolution, bit depth, coloring. This database could be considered as a representative sample of medical images in common hospital operation. Method for finding of minimum size of Region of Non-Interest (RONI) in the images from different types is presented. Results for whole database and certain modalities are depicted. |
