Abstract: [Problem] To provide a digital data encrypting method with which data concealment is enhanced. [Solution] A data encrypting method using an encrypting apparatus, the method including a first partial data input step in which first partial data that is a portion of data is inputted to the encrypting apparatus, a first encryption step in which the first partial data is encrypted and first encrypted data is obtained, a first partial data erasure step in which the first partial data is erased from the encrypting apparatus, a second partial data input step in which second partial data that is partial data of the aforementioned data other than the first partial data is inputted to the encrypting apparatus, and a second encryption step in which the second partial data is encrypted and second encrypted data is obtained.

Abstract: To provide a highly confidential data management system. Provided is a data management system comprising: a data division unit 17 that obtains first data 13 and second data 15 obtained by dividing source data 11; a first data storage unit 19 that stores the first data 13; a code conversion unit 21 that obtains coded second data by converting the second data 15 into code information; a coded second data output unit 23 that outputs the coded second data as outputted coded second data; a code information reading unit 25 that reads the coded second data on the basis of the outputted coded second data; and a data restoration unit 27 that, on the basis of the coded second data read by the code information reading unit 25, reads the first data from the first data storage unit, and restores the source data.
