Abstract
In an information processing apparatus which can encrypt a file and can store the encrypted file at a predetermined location, an input file is separated into a header field and data field, and the separated data field is encrypted and saved in association with information included in the header field. In the meantime, a keyword required to specify the file is extracted from the separated data field, and the extracted keyword is converted into a hash value. The obtained hash value is stored in association with the information included in the header field. Upon storing a file, the contents of the file after storage can be prevented from being easily recognized by a third party.
