Developing Filtering Techniques for Securing Vector Graphics Images Applied to Ubiquitous Patient Records

摘要

In this article we are describing the security challenges with the use of SVG Vector Graphics for ubiquitous patient records. Moreover, we are presenting an architecture that incorporates security mediators in the form of SVG filers to provide a highly flexible approach for accessing Electronic Patient Records. The SVG filters are based on the SAX primitives to pushes pieces of the SVG to the encryption/decryption handlers. The SAX handlers can filter, skip tags, or encrypt tags partially or universally at any time from the stream of the SVG. The SVG encryption/decryption techniques used by the SAX filters implements the standard specification of the W3C XML Encryption.
