New trends in security of electronic health documentation

Implementation and transmission of health documentation in electronic form stimulate higher requirements for their security. New possibilities of using XML technology for obtaining secured electronic health record are presented in this paper. It means integration of security techniques based on using of language XML. These technologies open new possibilities in encryption and sign of documents (XML signature, XML encryption) and also in secured access to sources. The contribution is focused to description of some relevant parts of XML security, their interactions, and examples in medical environment (implementation, transmission, archiving, etc.). XML security is a new trend of security. Its some parts are today developed. The aim of using of XACML and SAML in XML security is to develop security complex mode with possibilities of different approaches to electronic health documentation for different group of users. Description of languages XACML and SAML is presented also. These languages are part of XML security and are not frequently used in practical applications for the present. The languages XACML and SAML make possibilities for transmission of secured information and they set detailed access to different parts of documentation for different groups of users (granularity). Concrete realization of developed theoretical model in medical environment is described, too. For proposed realization was used language XACML.
