Abstract: A position identification unit (110) maps a plurality of tumor sample reads to a human genome sequence, and identifies, for each target gene, a target position which is a genome position of a base, the genome position having changed with respect to the human genome sequence. A frequency calculation unit (120) calculates a variant allele frequency for each target position of each target gene. A distance calculation unit (130) calculates, for each target gene, a feature distance equivalent to a difference between a variant allele frequency corresponding to a peak density and a reference variant allele frequency in a density distribution indicating a density of the number of mapping reads with respect to the variant allele frequency. A coefficient calculation unit (140) calculates a correction coefficient using the feature distance of each target gene.

Abstract: In a personal searching-purpose ID (511), a personal encryption ID (512) and encrypted personal information (513) stored in a personal information storage unit (51), a disclosure range of personal information is embedded. Also, in a medical searching-purpose ID and a medical encryption ID stored in a medical data storage unit, a disclosure range of medical data is embedded. A search query generation unit generates a search query Q by encrypting a search anonymous ID subject to searching acquired from a user with attribution information of the user embedded. Then, a searching unit executes confidential searching on the personal searching-purpose ID (511) and a pathological searching-purpose ID (521), using the search query Q. The searching unit outputs a searching result acquired based on the attribution information of the user, the disclosure range of personal information and the disclosure range of medical data.

Abstract: An object is to enable to search genetic information in an encrypted state. An encryption apparatus (200) encrypts a target gene which is genetic information to be stored in a storage apparatus and generates an encrypted gene, as well compares a reference gene which is predefined genetic information with the target gene to generate differential information, and generates an encrypted tag which is encrypted by embedding the generated differential information. A data center (400) stores the encrypted gene with related to the encrypted tag in the storage apparatus. A search apparatus (300) generates a search query which is encrypted by embedding the differential information as a search keyword, and sends the generated search query to a data center (400). The data center (400) specifies the encrypted tag including the differential information specified in the search query, extracts the related encrypted gene, and sends the encrypted gene to the search apparatus (300).
