The present invention relates to a method and a system for identifying original data by using a data order. A data management apparatus according to the present invention comprises: a converted-data set generation unit for generating a converted-data set by randomly shuffling an order of rows or columns of an original data set including rows and columns; and a data management unit for providing a converted-data set to a user terminal, and storing information on an order of rows or columns of the converted-data set including randomly-shuffled data of an original data set, corresponding to information of a user who has received the converted-data set.
