Abstract – In this paper, we address Privacy-preserving classification problem in a multi-party sense. We focus the general classification in a secured manner and introduce a Privacy-preserving decision tree classifier using C4.5 algorithm without involving third party. C4.5 algorithm is a software

This paper studies how to build a decision tree classifier under the following scenario: a database is vertically partitioned into two pieces, with one piece owned by Alice and the other piece owned by Bob. Alice and Bob want to build a decision tree classifier based on such a database, but due

Classification for very large datasets has many practical applications in data mining. Techniques such as discretization and dataset sampling can be used to scale up decision tree classifiers to large datasets. Unfortunately, both of these techniques can cause a significant loss in accuracy. We

and to be of general usage these primitives should be rather building blocks than implementations of specific algorithms. In this paper, we describe primitives for building and applying decision tree classifiers. Based on the analysis of available algorithms and previous work in this area we have identified operations

to incorporating privacy mechanism and allow to hide sensitive pattern or itemset before data mining process is executed. This paper mainly focuses on general classification technique decision tree classifier for preserving privacy. It presents a survey on decision tree learning on various privacy techniques.

classifiers are used extensively for different types of tumor cases. In this paper, performance of decision tree induction algorithms on tumor medical data sets in terms of Accuracy and time complexities are analyzed.
