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?

该项目将能够处理完全加密的电话数据，以促进云端或本地的安全语音对话，只有最终用户才能访问结果。用户将能够存储，搜索和转换为文本的任何音频或电话文件的方式，不能拦截或干扰的云提供商，或任何第三方在传输链。目前，用户可以选择完全隐藏他们的语音数据以进行传输和存储，或者“明文”传输。然而，每一种选择都涉及到一个妥协：安全的通信不能使用云中可用的处理能力进行搜索或处理，而未加密的通信可以被处理成文本，或者可以搜索到大量的异地存储，但这会损害通信的隐私。这个项目将适应最初应用于基因组学的技术，并重新解释它们，以解决迄今为止最大的数据隐私挑战之一：如何在充分利用云计算搜索和存储功能的同时，保持对隐私的控制？
