health history created in a word-processing program. The health history compiled in computer based software can be printed, copied, and shared with anyone with a compatible word processor. PHR software can provide more sophisticated features such as data encryption, data importation, and data sharing with health care providers. Some PHR products allow the copying of health records to a mass-storage device such as a CD-ROM, DVD, smart card, or USB flash drive. PC-based PHRs are subject to physical loss and damage of the personal computer and the data that it contains. Some other methods of device solution may entail cards with embedded chips containing health information that may or may not be linked to a personal computer application or a web solution. Web applications Web-based PHR solutions are essentially the same as electronic device PHR solutions, however, web-based solutions have the advantage of being easily integrated with other services. For example, some solutions allow for import of medical data from external sources. Solutions including HealthVault, and PatientsLikeMe allow data to be shared with other applications or specific people. Mobile solutions often integrate themselves with web solutions and use the web-based solution as the platform. A large number of companies have emerged to provide consumers the opportunity to develop online PHRs. Some have been developed by non-profit organizations, while others have been developed by commercial ventures. These web-based applications allow users to directly enter their information such as diagnosis, medications, laboratory tests, immunizations and other data associated with their health. They generate records that can be displayed for review or transmitted to authorized receivers. Despite the need for PHRs and the availability of various online PHR providers, there has not been wide adoption of PHR services. E.g. Google discontinued its PHR service called Google Health on January 12, 2012. The reason cited for shutting down Google Health was that the service did not translate from its limited usage into widespread usage in the daily health routines of millions of people. Surveys of web-based services have found wide variations in functions between services and only limited data on efficacy and safety concerns. One analyst, describing the public's reluctance to adopt the services, called PHRs "a technology in search of a market." An emerging standard from HL7, Fast Healthcare Interoperability Resources (FHIR), is designed to make it easier for developers of personal health record applications to access relevant medical records.
