英文摘要：

The mining method of the sequential patterns for invasion events is constructed and loaded with the privacy preservation. Algorithm is optimizedand its operating cycle is shorten. All the above is obtained by adopting the MSAP algorithm, data pre -processing, generating the global sequence of attacking, con- structing the database of candidate pattern, obtaining the maximum set of the attacks and the maximum se- quence of attacks, and loading privacy preservation. Experimental results show that the QSPM algorithm and the PQSPM algorithm have obvious advantages over the original algorithm in the aspects of operating cycle and efficiency and the two algorithms have better performance in mining of the sequential patterns for inva- sion events.
