Scalar Product Protocol is the keystone in building privacy-preserving decision tree.
标量积协议是构造隐私保持决策树的关键技术。
And comparing with the performance of simple Scalar Product Protocol without privacy preserving, the performance of Protocol 4.1 is acceptable.
同时与简单的标量积协议的性能相比较，协议4.1的性能是在合理的范围之内。
A decision tree classifier was applied and a scalar product protocol was added, so that the need of privacy preserving is satisfied as well as the advantage of decision tree is retained.
在传统的决策树算法中引入标量积协议，既保持决策树算法本身的优点，又满足了保持隐私的需求。
