A personal information protection management system for genomic data includes data storage, role storage, a filter, and a data output part. The data storage is configured to store genomic data. The role storage is configured to store an identifier of a data output destination and a role in association with each other, the role including a detail of filtering for removing from genomic data a part that is not to be outputted. The filter is configured to filter the stored genomic data based on the stored role. The data output part is configured to output the filtered genomic data to the data output destination. The filter is configured to obtain a data request signal transmitted from the data output destination and, based on the role that is associated with the identifier included in the obtained data request signal, filter the genomic data.

An encryption key generating device includes a shared key separator separating a shared key into a first key and a second key and storing the first key in a non-volatile memory and storing the second key in a volatile memory; a key extender extending the second key to the same key length as that of the first key and storing the second key extended as a third key in the volatile memory; a key calculator calculating an encryption key by an exclusive-OR of the first key and the third key and storing it in the volatile memory.
