“…However, without de-identifying those PHIs in an unstructured text may pose a risk to disclose of patient identity. In order to de-identify the PHI in free text format, some methods [20][21] had been proposed, that approaches may be customized to work on other free-text medical records. Deidentification of free text is a very complex work that PHI might not be complete de-identified or incorrectly deidentified.…”

In addition to the primary care context, medical images are often useful for research projects and community healthcare networks, so-called "secondary use". Patient privacy becomes an issue in such scenarios since the disclosure of personal health information (PHI) has to be prevented in a sharing environment. In general, most PHIs should be completely removed from the images according to the respective privacy regulations, but some basic and alleviated data is usually required for accurate image interpretation. Our objective is to utilize and enhance these specifications in order to provide reliable software implementations for de-and re-identification of medical images suitable for online and offline delivery. DICOM (Digital Imaging and Communications in Medicine) images are de-identified by replacing PHI-specific information with values still being reasonable for imaging diagnosis and patient indexing. In this paper, this approach is evaluated based on a prototype implementation built on top of the open source framework DCMTK (DICOM Toolkit) utilizing standardized de-and re-identification mechanisms. A set of tools has been developed for DICOM deidentification that meets privacy requirements of an offline and online sharing environment and fully relies on standardbased methods.

“…EHRs are managed by healthcare providers [6,37] (in our system, healthcare providers are data consumers). However, patients may have to follow various policies, such as medical, dental, and vision, registered with different insurance companies which make it hard for all parties to access up-to-date EHR records every time.…”

“…In 1996, the Health Insurance Portability and Accountability Act (HIPAA) offered some general guidelines to enforce the protection of private medical information [8]. The entities covered under the HIPAA are required by law to protect the users' information, thus increasing user confidence in these PHRs.…”

Health service providers are starting to become interested in providing PHRs (Personal Health Records). With PHRs, access to data is controlled by the patient, and not by the health care provider. Companies such as Google and Microsoft are establishing a leadership position in this emerging market. A number of benefits can be achieved with PHRs, but important challenges related to security and privacy must be addressed. This paper presents a review of the privacy policies of 20 free web-based PHRs. Security and privacy characteristics were extracted and assessed according to the HIPAA standard. The results show a number of important differences in the characteristics analyzed. Some improvements can be made to current PHR privacy policies to enhance the audit and management of access to users' PHRs. A questionnaire has been defined to assist PHR designers in this task.
