Hello,

Welcome to NEMOS LAB


ABOUT US



Our group is in the Department of Computer Science at Colorado School of Mines.

Much of our work focuses on game theoretic and optimization apapproaches to networking, IoT, mobile computing and sensing, security and privacy.

We are looking for self-motivated and hardworking students who are interested in tackling algorithmic, optimization, and economic challenges across different areas, including networking, crowdsourcing, smart grid, and security and privacy.

OUR PROJECTS



Description

In auction-based incentives for crowdsensing, Sybil attacker could benefit by submitting multiple bids under multiple fictitious identities (Sybils). In this project, we designed both online and offline Sybil-proof incentive mechanisms for crowdsensing.

Description

Want to unlock your phone when your hands are wet or dirty? In this project, we design UltraUnlock, which provides silent, quick, and smooth user experience for unlocking. UltraUnlock exploits ultrasound from your smartphone to detect user’s unique hand movements for smartphone authentication.

Description

Crowdsensing enables a wide range of data collection, where the data are usually tagged with private locations. In this project, we consider the trade-off between location privacy and location information quality from optimization perspective in crowdsensing.

Description

InterPlanetary File System (IPFS) is a peer-to-peer hypermedia distribution protocol which aims to be the foundation for a new, distributed Internet. In this project, we develop, analyze, and test strategies to incentivize cooperation between users in IPFS.

MaskCall protects users’ speech privacy when they are making phone calls. The smartphone will send sound signals opposite to a user’s voice, so that people around the user can not hear what the user is saying.

Description

Voice-controlled assistants are becoming pervasive these days. However, what if bad guys record your voice and send commands you do not want? We design VCGuard, which makes electronic speakers generate buzz noises when replaying your voice. In this way, only voices from human beings would be accepted.

Description

Inspired by the experience of people asking for directions indoors in daily life, we proposed iIN, an instruction-based indoor navigation system. Taking into consideration both the distance and landmarks, iIN selects a route and generates instructions on how to navigate to the destination.
