发明名称 PROTECTING USER IDENTIFIABLE INFORMATION IN THE TRANSFER OF TELEMETRY DATA
摘要 This disclosure describes systems and method for preventing the transfer of ‘user-identifiable information’ from a client device while collecting telemetry data that is relevant to features of an operating system or computing application. In various examples, telemetry data is gathered to monitor the performance or use of an operating system or computing application. The process of collecting telemetry data can involve capturing data associated with files that are not directly associated with the operating system or computing application that is being monitored. This disclosure presents techniques that use a cryptographic hash function to prevent user identifiable information from being revealed in file attributes during the process of collecting telemetry data. A user's privacy is protected by the computational impracticability of recreating the original filename from the hash value.

主权项 1. A computer-implemented method, comprising: receiving, using a server, a first list of files, the first list of files including a hash value in place of a filename for a file in the first list of files; comparing the hash value of the filename from the first list of files to a hash value of a filename from a second list of files; determining that the hash value of the filename from the first list of files matches the filename from the second list of files; identifying an original filename for the hash value of the filename that matches; and generating a third list of files, by replacing on the first list of files, the hash value of the filename that matches with the original filename identified.
