Abstract: A data sequence prediction method includes calculating, based on historical data sequences of N objects, a similarity distance between every two objects of the N objects, to obtain a similarity distance set, where the similarity distance is used to represent a similarity degree of two objects, the historical data sequence includes a plurality of pieces of data arranged according to a preset rule, and N is a positive integer greater than 1, dividing the N objects into K prediction object classes based on the similarity distance set using a clustering algorithm, where K is a positive integer, and K≤N, and predicting a future data sequence of an object included in at least one prediction object class of the K prediction object classes.

Abstract: A data storage method includes receiving to-be-stored first data; encrypting a first data part in the to-be-stored first data; writing an encrypted first data part into a non-volatile memory; and then writing a second data part into a hard disk or a magnetic disk.
