1. A forensic index method by distributed processing, comprising:
generating data to be divided by dividing data to be indexed according to predetermined division setting for distributed processing; allocating the generated data to be divided to a plurality of data processing units according to the predetermined division setting, extracting an index by filtering the allocated data to be divided in the plurality of data processing units, and generating divided index data including the extracted index using the plurality of data processing units; and generating an index database by merging the generated divided index data, wherein generating the index database comprises: when a new index is generated in the index database from the merged generated divided index data, setting an index database identifier as a key in the index database and adding the merged generated divided index data to a list of data corresponding to the key; and when generated index data corresponds to a file being added to an existing index, generating a temporary index data having a temporary index using the generated index data and adding the temporary index to a list of data corresponding to the key of the existing index.
