A breach of privacy will certainly result in some financial payout, which at least lower bounds the financial value of privacy in that context (not to speak of the repercussions from loss of reputation or even loss of federal funding).<br /><br />By way of a (even personally un-convicing) stab at the value of a single individual's record's privacy, just blindly assume each individual's privacy holds an equal share of the value lost by such an organization due to a breach.<br /><br />Obviously the issue is more complex -- what would you need to pay a doctor to release patient information, conditioned on the event that the breach would have the *worst-case* (purely financial) outcome for the doctor? At least enough to offset the value of every patient's information becoming public. But then, in the real world, a doctor with no moral qualms about making an unethical profit might have a high chance of getting by unscathed.<br /><br />In light of that, the only truly privacy preserving mechanism *purely in practice* appears to be the result of "aggregate privacy" -- if only one individual's privacy is on the line, the cost is only epsilon - next to nothing. But when a large group combines their private data, the cost of revealing a single individual's is effectively the cost of revealing it all.<br /><br />Hence, the current almost-contradictory situation where social network personal information - personal relationship status, religious beliefs, sexual preference - is surprisingly open, but knowing whether someone went to the doctor with a sniffle is locked up tight.Daniel Aponnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-4485812432555660072011-09-03T13:53:10.026-05:002011-09-03T13:53:10.026-05:00@Jonathan Katz,

We can say the same thing about other things like car insurance, or medical insurance, ... . Ordinary people lack the knowledge and expertise to judge the risks and the value of these things. Legally a contract between two parties can be annulled on the base of lack of information by one side at the time they signed the contract. Expecting ordinary users to be able to judge the value of privacy is not reasonable.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-83693005208737834312011-09-03T02:00:42.944-05:002011-09-03T02:00:42.944-05:00A son of Russian antivirus guru Kaspersky was kidn...A son of Russian antivirus guru Kaspersky was kidnapped based on the information from his social network account.<br /><br />http://eng.cnews.ru/news/top/indexEn.shtml?2011/05/19/440795<br /><br />Also any leak of phone numbers is a source of fraud.

Ask them to assign a dollar amount: how much would they be pay in order to protect the privacy of that piece of information? Or, conversely, how much could you pay them in order to get them to agree to make the information public. No one has any clue how to price this, which is why it is undervalued in the marketplace.Jonathan Katzhttps://www.blogger.com/profile/07362776979218585818noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-28166979280013309912011-09-02T13:57:24.748-05:002011-09-02T13:57:24.748-05:00It was one of the physicists from my days at NEC R...It was one of the physicists from my days at NEC Research.

Of course you can think that you can trust them, but don't expect others to have the same feelings.<br /><br />You are asking what can go wrong? You are asking about real problems? Don't you follow the news? Just check the people who are in prison in Bahrain or China because of their online discussions that they falsely believed to be secure. Haven't you heard the recent CA fiasco? I personally know people who have been jailed and the evidence was their chat history on yahoo.<br /><br />Now, you may think that as an American citizen you are safe and you can at least trust US government and big American business about your private information. I don't agree with that, but let's put that aside, and assume that I agree, even then people have demonstrated that putting information online is risky, and they did demonstrate it on people who didn't agree with them, like Google founder and some US senators. If you are sincere about your belief that privacy is not important and putting information online is not risky, then challenge them and they will teach you how important privacy is.

Online footprinting of a certain individual working in a sensitive position may give a lot more information on how he could be persuaded (either with or against his will) to uncover otherwise classified information related to his work.
