This research will study the SPMP (Selective Private Model-basedPrediction) problem demonstrated with the following scenario: A clientwith a private input wants to use a server's private model to makepredictions; however, neither side wants to disclose its private data toanybody. More specifically, the research will study the problem forselected models including the Hidden Markov Model, the Neural NetworkModel, the Bayesian Network Model, and the Decision Trees Model. The goalis to develop efficient and practical solutions that enable such type ofprivacy preserving prediction.The project will investigate two approaches: commodity-server approach andmultiple-server approach. The commodity-server approach uses thecommodities (data) from a third party to preserve the confidentiality ofthe private data. The multiple-server approach uses duplicate servers sono single server can learn all information about the client's data. Basedon these two approaches, various data disguising techniques will also bestudied.Efficient solutions to the SPMP problems enable model owners to providenew forms of e-commerce services while protecting customers' privateinformation. Furthermore, the results, methodologies, and the buildingblocks gained from the proposed activity can provide invaluableunderstanding and insights into the Secure Multiparty Computation (SMC)research, and help to advance and expand the areas of SMC research.---------------------------------------

本研究将研究以下场景演示的 SPMP（基于选择性私有模型的预测）问题：具有私有输入的客户端想要使用服务器的私有模型进行预测；然而，双方都不想向任何人透露其私人数据。更具体地说，该研究将研究选定模型的问题，包括隐马尔可夫模型、神经网络模型、贝叶斯网络模型和决策树模型。目标是开发有效且实用的解决方案，以实现此类隐私保护预测。该项目将研究两种方法：商品服务器方法和多服务器方法。商品服务器方法使用来自第三方的商品（数据）来保护私有数据的机密性。多服务器方法使用重复的服务器，因此单个服务器无法了解有关客户端数据的所有信息。基于这两种方法，还将研究各种数据伪装技术。 SPMP问题的有效解决方案使模型所有者能够提供新形式的电子商务服务，同时保护客户的隐私信息。此外，从拟议活动中获得的结果、方法和构建模块可以为安全多方计算 (SMC) 研究提供宝贵的理解和见解，并有助于推进和扩展 SMC 研究领域。-------- -------------------------------------------
