The vault is open
BACK in 2000, Steve Ballmer, Microsoft's chief executive, described a grand vision for the future of health care. One day, he said, everyone would have a secure and private website on the internet on which their doctors could post their “scans, lab results, test results, visit minutes” and the like, and to which the owner could grant certain people access, to view some or all of that information.
His ideas met with guffaws from the old lags of the industry, who have seen many fancy schemes for electronic medical records fall flat. America's health sector is simply too balkanised and too paper-based to stitch together easily in digital form. Google, Intel, Revolution (a firm started by Steve Case, a founder of AOL) and other Silicon Valley firms have all tried to do this, with little success. Even Mr Ballmer conceded back then that he was searching for the “holy grail” of healthcare.
And yet, after years of frustration and furious development work, Microsoft now believes it has realised Mr Ballmer's dream. On Thursday October 4th the software giant unveiled its new health-information product at a big event in Washington, DC. It is called the Health Vault, in keeping with Microsoft's promise to make storing data on the internet just as secure as keeping it in a bank.
Health Vault will store all its customers' health data, ranging from test results to doctors' reports to daily measurements of weight or blood pressure, online. Individuals then have access to those records any time, anywhere, via the internet—a great boon for those who travel a lot. Medical offices and hospitals who sign up for the service could easily send test results in digital form to the vault, and patients could authorise them in turn to have access to various, carefully circumscribed bits of their personal data.
Microsoft also announced that several dozen manufacturers, hospitals and charities have signed up for Health Vault. Big names including the American heart, diabetes and lung associations, the NewYork-Presbyterian Hospital, and Omron and Texas Instruments, in addition to various firms devoted to the craze for “wellness”, are all now on board, and are expected to announce products and services shortly.
If the software giant has really found a hacker-proof way of storing records online, then the benefits of Health Vault are clear. But use of the vaults will be free both for the individuals that sign up for them and for the vendors and doctors that provide services based on the information they contain. So how will Microsoft make any money?
Sean Nolan of Microsoft explains that the business model depends on one thing: targeted search. Microsoft is betting that people will use its Health Vault Search to find out about their ailments. This service relies on an approach known as “vertical search” which attempts to provide more relevant results than generalist search engines like Google and Yahoo! by specialising in a particular field. The firm's recent acquisition of Medstory, a vertical-search engine focusing on health care, has given it a boost in this area.
Health Vault's search engine would definitely work better than those of rival sites if it could examine users' health records and past queries, and thus provide the responses that are most relevant to each individual's situation. But in order to attract any users in the first place, Microsoft has promised to enforce strict privacy rules. These, says Mr Nolan, would preclude such data-mining.

Somehow, this doesn't fill me with a great deal of confidence. And what's more, Microsoft are potentially opening up themselves to some incredibly serious litigious action if any of it fails.
