Abstract: The invention described herein is directed to methods and systems for protecting network trace data. Network traces are used for network management, packet classification, traffic engineering, tracking user behavior, identifying user behavior, analyzing network hierarchy, maintaining network security, and classifying packet flows. In some embodiments, network trace data is protected by subjecting network trace data to data anonymization using an anonymization algorithm that simultaneously provides sufficient privacy to accommodate the organization need of the network trace data owner, provides acceptable data utility to accommodate management and/or network investigative needs, and provides efficient data analysis, at the same time.

Abstract: The invention provides a piezoelectric micro-electromechanical system (MEMS) microphone includes a base with a cavity and a piezoelectric diaphragm arranged on the base. The base has a ring base and a support column. The piezoelectric diaphragm includes a plurality of diaphragm sheets. Each diaphragm sheet has a fixing end connected with the support column and a free end suspended above the cavity. The widths of the diaphragm sheets are gradually increased from the fixing ends to the free ends. According to the piezoelectric MEMS microphone provided by the invention, under sound pressure, the free ends vibrate, wide free ends drive short fixing ends, and the diaphragm sheets close the fixing ends generate greater deformation to generate more charge. Therefore, the sensitivity can be further improved.
