Privacy preserving speech processing in the cloud

该项目将能够处理完全加密的电话数据，以促进云或本地的安全语音对话，这样只有最终用户才能访问结果。用户将能够存储、搜索并将电话文件的任何音频转换为文本，而不会被云提供商或传输链中的任何第三方拦截或干扰。目前，用户可以选择完全加密他们的语音数据进行传输和存储，或者“透明”传输。然而，每一种选择都涉及到一种折衷：安全通信不能使用云中的可用处理能力进行搜索或处理，而未加密的通信可以处理为文本，或者使其可用于大量场外存储，但这会损害通信的隐私。该项目将采用最初应用于基因组学的技术，并对其进行重新解释，以解决迄今为止最大的数据隐私挑战之一：如何在利用云计算搜索和存储功能的同时保持对隐私的控制？

The project will enable the processing of fully encrypted telephone data to facilitate secure voice conversationsin the cloud, or locally, such that only the end-user has access to the results. A user will be able to store, searchand convert to text any audio of telephone file in a way that cannot be intercepted or interfered with by acloud provider, or any third party in the transmission chain. Currently, a user has the choice of fully encryptingtheir voice data for transmission and storage, or transmitting it "in clear". However, each choice involves acompromise: The secure communication cannot be searched or processed using the processing poweravailable in the cloud whereas the unencrypted communication can be processed into text, or made searchablefor mass off-site storage but this compromises the privacy of the communication.This project will adapt techniques originally applied to genomics, and re-interpret them to solve one of thegreatest data privacy challenges to-date: How can you keep control of privacy, while leveraging the power ofthe cloud for search and storage?
