Outline of Final Research Achievements

If an individual genome is disclosed and the holder is identified, the person's sensitive information is disclosed. This problem is similar to the statistical disclosure control problem. We need methods to suppress the probability that a sample unique genome with some concealment becomes population unique. The fundamental statistical model is a random partition. In this research, the purpose was establishment of methodology for assessment of disclosure risk and confidentiality of individual genome. A computational method for a random partition with accounting correlation among points on a genome is proposed, and asymptotic properties of Gibbs-type partitions, which are in a general class of random partitions, were discussed. The methods for assessment of disclosure risk and confidentiality were discussed with people who obtain individual genome data and use them.
