摘要： According to one embodiment, an encryption device encrypts each of numerical values based on an encryption key, and generates encrypted data. On the basis of each of the encrypted data, a computation device generates a primary computation result corresponding to data in which a computation result of an expression that has added and subtracted each of the numerical values is encrypted. On the basis of the primary computation result, a secondary computation key and random numbers, a computation assist device generates a secondary computation result. The computation device generates a tertiary computation result based on the secondary computation result and a tertiary computation key, and decides the magnitude relation between a minuend and a subtrahend in the expression based on the tertiary computation result.

摘要： An anonymization indicator computation system of the embodiment includes a data storing device, an anonymization device, an anonymization degree computation device, and an addition degree computation device. The data storing device stores original data including a value for each item for each person. The anonymization device generates anonymized data from the original data by anonymizing values of part of items in the original data. The anonymization degree computation device computes the anonymization degree indicating a degree of anonymizing data based on the anonymized data. The addition degree computation device computes the data addition degree indicative of a probability of generating the anonymized data from the original data.

摘要： According to one embodiment, an anonymization apparatus according to an embodiment is configured to execute a determination process, a division process, and a process of recursively executing at least the determination process and the division process, and to thereafter execute anonymization. A number-of-kinds calculation circuit calculates a number of kinds of different attribute values for each of a plurality of attributes, before the determination process is executed. A determination circuit determines the attribute to be noticed, based on also the calculated number of kinds. A sort circuit sorts a plurality of personal data items, based on the calculated number of kinds, before the division process is executed.

摘要： A data management device according to an embodiment stores first encrypted data obtained by encrypting plain text data with a first public key of a first user device. The data management device stores a first re-encryption key for re-encrypting the first encrypted data without decrypting to obtain first re-encrypted data decryptable with a private key of a second user device. The data management device stores a conversion key generated from a first private key corresponding to the first public key and a second private key of the first user device. The data management device converts the first encrypted data into second encrypted data with the conversion key. The data management device The data management device converts the first re-encryption key into a second re-encryption key with the conversion key.
