Identifying a Culprit In a Bloodbath

worromot writes "A group of geneticists published a method to determine if a given individual's DNA is present in a mixture (e.g., in a pool of blood on a carpet). An individual's DNA can comprise less than 1% of the mixture. (The article is in open access on PLoS Genetics website.) While this is a potential boon for forensics, there are more immediate worries about the privacy of the participants of the genetics studies that had been under way for many years. As Science magazine writes, 'The discovery that a type of genetic data that is widely shared and often posted online can be traced back to individuals has prompted the US National Institutes of Health and the Wellcome Trust to strip some genetic data from their publicly accessible Web sites and NIH to recommend that other institutions do the same.' The gravest worry was that an individual who had someone's genetic code could determine, based on the pooled data, whether the person participated in a disease study and whether they were in the disease group, or thereby glean private health information. NIH plans to ask institutions that have posted pooled data on their own Web sites to take these down, too."

The Internet is like a permanent stain

Good luck with taking that stuff down. Posting something on the Internet is like spilling grape juice on a white cloth. If it wasn't made obvious by the age controversy over China's gymnasts, then I'll say it again: once something is on the Internet it stays there, no matter how much scrubbing you do. People need to think first and to not put something up if there is ever a chance it will be an issue.
