Tutorial I: Privacy-Aware Smart Metering

Organizers: Deniz Gunduz (Imperial College London, London, UK), Tobias Oechtering (KTH Royal Institute of Technology, Stockholm, Sweden)

Description:The electrical grid is a highly complex cyber physical system, vital for our society and economy. For efficient and reliable electrical energy generation and distribution, advanced control mechanisms have been introduced into the grid. These mechanisms help us monitor the grid in order to rapidly diagnose potential problems, and to dynamically react to variations in demand and supply. Smart electricity meters (SMs) are an essential component of the smart grid control mechanisms; they provide accurate sensing capabilities, and establish a two-way communication infrastructure. SMs also enable demand side management, potentially responding to real-time pricing, and exploiting the growing elasticity in energy consumption of users. SMs can be further linked with smart water and gas meters to better manage energy infrastructure for smarter/greener homes.

However, SM readings can also reveal users habits and behaviours since every electric appliance has its own detectable power consumption signature. Using these signatures together with non-intrusive load monitoring (NILM) techniques can easily lead to real-time surveillance of users activities. Hence, there is a significant tension between sharing data for the reliability and efficiency of the grid, and consumer privacy. Since SM readings are transmitted over communication networks shared by other users and applications, the system is vulnerable to attacks that may hack and manipulate SM readings of users and energy costs, fake power consumption data at a large scale to stress or crash the entire power network.

This half-day tutorial will provide a comprehensive overview of growing privacy threats to SMs and the smart grid in general. Potential attacks and their impact on the grid will be reviewed. We will then go over various techniques in the literature against the potential attacks. We will provide an overview of the tools that can be employed to guarantee that SMs can continue to play their essential role in enabling the future smart grid without threatening user privacy.

Tutorial Overview:

• Objectives

As the integration of renewables into the energy network increases, and storage devices, in the form of electric car batteries or elasticity of consumption, become widely available, the capability for real time control and monitoring at the customer end is becoming increasingly important as it provides the means to balance the variability and intermittency of the renewable resources. As a consequence, pricing and billing are becoming extremely dynamic and complex. The more distributed and the less deterministic the electricity network becomes, due to distributed renewable resources, the smarter the grid will need to be to ensure reliable operation. Utility providers need to gather higher resolution information in order to track the network state accurately, detect failures quickly, prevent energy theft, and foremost, increase the efficiency through real-time pricing and demand side management. Therefore, resolving the privacy concerns in smart grids is an urgent challenge for its successful development.

We will open the tutorial with an overview of the main objectives of SMs, and how these objectives lead to privacy threats. We will then review how the current SM systems function.

• Challenges and Tools

In addition to privacy threats from third party intruders, SMs present another intrinsic privacy threat, which is significantly more challenging compared to classical data privacy. SMs are installed specifically to provide finegrained information on the energy consumption of users and the state of the grid to the utility provider. Although the utility provider is the intended recipient of the SM readings, it is not fully trusted by the consumers. SM privacy constitutes even a greater risk for businesses, such as server farms, whose performance can be accurately tracked from their energy consumption profile. The SM infrastructure should be designed such that the information provided to the utility provider is good for control, state estimation, and billing purposes, yet it does not conflict with consumer privacy. This highly challenging task requires fundamental research in privacy assurance with applications to power systems.

The main goal of the tutorial will be to provide a comprehensive overview of these challenges, and present the existing techniques in the literature to tackle them. These will involve practical as well as more fundamental theoretical approaches.

• Concluding Remarks

Before concluding, we will provide a comparison of the different analytical approaches covered in the tutorial and discuss their implications on practical design. We close with a discussion on current and future challenges, in particular related to the design of privacy-aware smart grids.

Organizers: Fernando Pérez-González (University of Vigo, Spain), Simón Oya (University of Vigo, Spain)

Description:The Location based services have a pervasive presence in our society. From the usage of the phone to find nearby places to the simple act of connecting to the phone network, there is a vast amount of personal location information being collected by different service providers.

Tutorial III: Role of Adversaries in Deep Learning

link to presentation

Organizers: Mayank Vatsa (IIIT Delhi, India), Richa Singh (IIIT Delhi, India), Nalini Ratha (IBM T. J. Watson Research Center, USA)

Description:The Deep neural network architecture based models have high expressive power and learning capacity. However, they are essentially a black box method since it is not easy to mathematically formulate the functions that are learned within its many layers of representation. Realizing this, many researchers have started to design methods to exploit the drawbacks of deep learning based algorithms questioning their robustness and exposing their singularities. However, adversarial attacks on automated classification systems has been an area of interest for a long time. In 2002, Ratha et al. proposed eight points of attacks on a biometric system and several of these attacks are relevant for non-biometric classification tasks as well, including object recognition and autonomous driving. For instance, the adversary can operate at the input level or the decision level, and lead to incorrect prediction results by the classifier. Therefore, it is important to detect the adversarial perturbations and mitigate the effect caused due to such adversaries.

The research on adversarial learning has three key components: (i) creating adversarial images, (ii) detecting whether an image is adversely altered or not, and (iii) mitigating the effect of the adversarial perturbation process. These adversaries create different kinds of effect on the input and detecting them requires the application of a combination of hand-crafted as well as learnt features; for instance, some of the existing attacks can be detected using principal components while some hand-crafted attacks can be detected using well defined image processing operations. This tutorial will focus on these three key ideas related to adversarial learning (aka perturbations, detection, and mitigation), building from basics of neural network, deep learning, adversarial learning to discussing new algorithms for detection and mitigation, and conclude with some of the research questions in this spectrum.

Target audience and Prerequisite:

This tutorial will be relevant to researchers and graduate students working in adversarial pattern recognition and deep learning. It is expected that the attendees will have fundamental knowledge of machine learning.

Outline of Tutorial:

The tutorial is planned to be organized under following broad sections and the duration will be around 4 hours.

  • Introduction to Neural Networks
  • Deep learning architectures

Tutorial IV: Biometric Template Protection and Evaluation

Organizers: Marta Gomez-Barrero

Description:The recent discussion on privacy protection, for instance within the framework of the new EU General Data Protection Regulation (GDPR), has raised privacy concerns regarding the storage and use of biometric data. The international standard ISO/IEC 24745 has established two main requirements for protecting biometric templates i) irreversibility and ii) unlinkability back in 2011. Since then, numerous efforts have been directed to the development and analysis of irreversible templates. However, only very recently, in 2018, a systematic quantitative manner to analyse the unlinkability of such templates was proposed. As a consequence, the lack of a unified framework to analyse all privacy aspects of biometric template protection schemes may have hindered their further deployment.

In this tutorial, we will focus on the objective and quantitative evaluation of biometric template protection schemes. To that end, the main concepts related to template protection will be introduced, together with a review of the main existing approaches. A unified framework for the evaluation and benchmarking will be subsequently described, including the recently proposed unlinkability metric. It should be noted that these metrics can be also applied in other areas of signal processing in the encrypted domain. Finally, we will assess the potential from this approach by evaluating the performance of two state-the-art techniques for biometric template protection: Bloom filters and Homomorphic Encryption.

Target Participants:
