Local Differential Privacy for Smart Meter Data Sharing

no code implementations8 Nov 2023 Yashothara Shanmugarasa, M. A. P. Chamikara, Hye-Young Paik, Salil S. Kanhere, Liming Zhu

In this paper, we propose a novel LDP approach (named LDP-SmartEnergy) that utilizes randomized response techniques with sliding windows to facilitate the sharing of appliance-level energy consumption data over time while not revealing individual users' appliance usage patterns.

Advancements of federated learning towards privacy preservation: from federated learning to split learning

no code implementations25 Nov 2020 Chandra Thapa, M. A. P. Chamikara, Seyit A. Camtepe

In practical scenarios, all clients do not have sufficient computing resources (e. g., Internet of Things), the machine learning model has millions of parameters, and its privacy between the server and the clients while training/testing is a prime concern (e. g., rival parties).

Privacy Preserving Face Recognition Utilizing Differential Privacy

no code implementations21 May 2020 M. A. P. Chamikara, P. Bertok, I. Khalil, D. Liu, S. Camtepe

Biometric information delivered to untrusted third-party servers in an uncontrolled manner can be considered a significant privacy leak (i. e. uncontrolled information release) as biometrics can be correlated with sensitive data such as healthcare or financial records.

SplitFed: When Federated Learning Meets Split Learning

2 code implementations25 Apr 2020 Chandra Thapa, M. A. P. Chamikara, Seyit Camtepe, Lichao Sun

SL provides better model privacy than FL due to the machine learning model architecture split between clients and the server.

Privacy Preserving Distributed Machine Learning with Federated Learning

no code implementations25 Apr 2020 M. A. P. Chamikara, P. Bertok, I. Khalil, D. Liu, S. Camtepe

Distributed devices such as the Internet of Things (IoT) often produce a large amount of data, eventually resulting in big data that can be vital in uncovering hidden patterns, and other insights in numerous fields such as healthcare, banking, and policing.
