1. An anonymizing apparatus comprising:
a processor configured to:
receive a first instruction from a first application program executed in a first apparatus;anonymize an anonymized part of first data by replacing the anonymized part of the first data with a hash value calculated using a hash key corresponding to a type of the first application program to generate a first modified anonymized part;transmit anonymized first data including the first modified anonymized part to the first apparatus;receive a second instruction from a second application program executed in a second apparatus;anonymize an anonymized part of second data to generate a second modified anonymized part by anonymizing the anonymized part of the second data based on information identifying the second data when the anonymized part of the second data is same as the anonymized part of the first data and a type of the second application program is same as the type of the first application program so that the first modified anonymized part is different from the second modified anonymized part; andtransmit anonymized second data including the second modified anonymized part to the second apparatus.
