To solve the problem of privacy preserving of the distributed decision-tree building process,this paper introduced the secure multi-party computation method and designed an algorithm of privacy preserving distributed C4. 5 algorithm ,which was applicable to the vertically and horizontally distributed dataset,and also proposed a new computation method of the degree of privacy protection. Experimental results demonstrate that the privacy preserving algorithm can well protect the original data from revealing,and keep high classification correct accuracy.
