This is the list of my publications roughly related to privacy in machine learning. Membership Inference: Machine learning model parameters can be probed to extract sensitive information about the training data samples [ ] [ ] . 2017. Membership Inference Attack 8 on Summary Statistics • Summary statistics (e.g., average) on each attribute • Underlying distribution of data is known [Homer et al. From Keys to Databases – Real-World Applications of … Membership Inference Attacks and Defenses in Semantic Segmentation 3 1.2 Related Work Recent attacks against machine learning models have drawn much attention to communities focusing on attacking model functionality (e.g., adversarial at-tacks [10,18,19,23,30,34]), or stealing functionality [24] or configurations [22] of a model. as a powerful mechanism for defending against attacks on machine learning models. Fredrikson et al. nature 323, 6088 (1986), 533. DEEP LEARNING WITH DIFFERENTIAL PRIVACY Martin Abadi, Andy Chu, Ian Goodfellow*, Brendan McMahan, Ilya Mironov, Kunal Talwar, Li Zhang Google (2015)], [Backes et al.

However, recent research has shown that ML models are vulnerable to attacks against their underlying training data. [10] that trains an attack model to recognize the differences in machine learning algorithm itself or the trained ML model to compromise network defense [16]. Above: Membership inference attacks observe the behavior of a target machine learning model and predict examples that were used to train it. Review of Membership Inference Attacks Against Machine Learning Models Security-based attacks can be segregated into two different categories depending on the leaning phase where they target a machine learning algorithm, including training-phase attacks and testing-phase (or inference-phase) attacks. As the purpose of machine learning is to notice and evaluate patterns beyond human recognition, using a machine learning model to attack black box machine learning models makes sense. The members identified by the attacker are not due to the randomness in machine learning process. R. Shokri et al. Membership Inference Attacks on Sequence-to-Sequence Models: Is My Data In Your Machine Translation System? querying. [12] introduced shadow model 49 training technique and performed membership inference attack against a deep classifier. 31,32,38,41] has evaluated the membership inference privacy risks of machine learning models, and demonstrate two key limitations that lead to a severe underestimation of privacy risks. Machine learning models leak significant amount of information about their training sets, through their predictions. Using MIAs, adversaries can inference whether a data record is in the training set of the target model. The figure below shows the accuracy loss of private models trainedwith naïve composition (NC) and Rè Introduction Recent sophisticated attack models has been successful in turning machine learning against itself with a view to leaking sensitive information contained in the target model’s training data. Follow. Machine learning (ML) has become a core component of many real-world applications and training data is a key factor that drives current progress. (2015) use their membership inference techniques to determine This includes both data privacy (protecting sensitive data used to train a model during the collection and learning process) and inference privacy (limiting what can be inferred about sensitive training data from an exposed model). a survey of attacks on private data.” In Annual Review of Statistics and Its Application, 2017. As most of my research is centred around model privacy, I was very keen on trying out the broad range of functionalities offered for the latter one. (2016)] on Machine Learning Models Our research focuses on understanding and mitigating privacy risks associated with machine learning. Learning Representations by Back-propagating Errors. After gathering enough high confidence records, the attacker uses the dataset to train a set of “shadow models” to predict whether a data record was part of the target model’s training data. LOGAN: Membership Inference Attacks Against Generative Models. Here the goal of the adversary is slightly different, instead of reconstructing training points from the output of the classifier the goal now is to infer whether a specific input was used to train the model. It further shows that the machine-learning approach outperforms the statistical attacks, and that learned models are transferable across different datasets. Google Scholar; Reza Shokri, Marco Stronati, Congzheng Song, and Vitaly Shmatikov. between two models that are trained on two neighboring datasets (only one includes data point x)? Shokri et al.10 is the rst work that de nes MIA and inspires a few follow-up studies. ML-Leaks: Model and Data Independent Membership Inference Attacks and Defenses on Machine Learning Models.

Sorami Hisamoto Matt Post Kevin Duh Works Applications Johns Hopkins University s@89.io {post,kevinduh}@cs.jhu.edu Abstract Data privacy is an important issue for “ma-chine learning as a service” providers. Face Off Report. Inference attacks aim to reveal this secret information by probing a machine learning model with different input data and weighing the output. Performing such membership inference attacks on generative models is a much more difficult task than it is on discriminative ones, as recently introduced by Shokri et al. Membership inference. We focus on the basic membership inference attack: given a data record and black-box access to a model, determine if the record was in the model's training dataset. .. We focus on the case of inferring the membership of a sample of customer message data in the training set of a language model. Machine Learning Models that Remembers Too Much C.Song, T.Risternpart, V.Shmatikov In ACM Conference on Computer and Communications Security (CCS), 2017 Membership Inference Attacks Against Machine Learning Models R.Shokri, M.Stronati, C.Song, V.Shmatikov A general framework that … One such sophisticated attack is the membership inference attack proposed by Shokri et al.

Ahmed Salem, Rui Wen, Michael Backes, Shiqing Ma, Yang Zhang. Membership inference attacks. Published: February 11, 2019 How to attack a model. I will also briefly mention some factors that increase a model’s vulnerability against membership inference attacks and protective measures. In this paper, we present the first membership inference attack against black-boxed object detection models that determines whether the given data records are used in the training. pdf But in general, machine learning models tend to perform better on their training data. We quantitatively investigate how machine learning models leak information about the individual data records on which they were trained. In other words, we turn the membership inference problem into a classification problem. Given that the target model … One of the mechanisms include : membership inference attack: Where a data record and black-box access to a model is used to determine if the record was in the model’s training dataset. Review of Membership Inference Attacks Against Machine Learning Models. proposed a membership inference attack to determine whether the training set contains certain data records [10]. A membership inference attack refers to a … Abstract: Machine learning models are prone to memorizing sensitive data, making them vulnerable to membership inference attacks in which an adversary aims to guess if an input sample was used to train the model. Related Work Membership inference attack (MIA). We propose and evaluate two novel membership inference attacks against recent generative models, Generative Adversarial Networks (GAN) [] and Variational Autoencoders (VAE) []These generative models have become effective tools for (unsupervised) learning with the goal to produce samples of a given distribution after training.Generative models thus have many applications … 5 minute read. 3 Membership Inference Attacks against Robust Models 3.1 Membership inference performance For a machine learning model F(we skip its parameters for simplicity) robustly trained with the perturbation constraint B , the membership inference attacks aim to determine whether a given input 2 Cynthia Dwork, Adam Smith, Thomas Steinke, and Jonathan Ullman. 4.2 MEMBERSHIP INFERENCE ATTACK Membership inference is the problem of assessing given a model and a data record whether that record was used in the training set of the model (Shokri et al. Attribute inference (guessing a type of data) and membership inference (particular data examples) are vital not only due to privacy issues but also as an exploratory phase for Evasion attacks. (2017)). Machine learning models have been known to leak information about the individual data records on which they were trained. There are various ways this can be achieved, such as, Membership Inference Attack [36], Model Inversion Attack [11], Model Poisoning Attack [25], Model Extraction Attack [42], Model Evasion Attack [3], Trojaning Attack [22], etc. In Proceedings of the 26th Annual Network and Distributed System Security Symposium (NDSS 2019). But in general, machine learning models tend to perform better on their training data. 10/18/2016 ∙ by Reza Shokri, et al. Privacy attacks against machine learning systems, such as membership inference attacks and model inversion attacks, can expose personal or sensitive information Several attacks do not require direct access to the model but can be used versus the model API Personalized models, such as predictive text, can expose highly sensitive information Given a blackbox machine learning model, guess if data was in the training data 2 [Shokri+ 2017] “Membership Inference Attacks against Machine Learning Models” Service Provider Machine Learning as a Service Blackbox Training Model User / Attacker Training Data Private Data Result Training API Prediction API For example, Truex et al.21 characterize the attack vul- But in general, machine learning models tend to perform better on their training data.

To address this concern, in this paper, we focus on mitigating the risks of black-box inference attacks against machine learning models. In this work, we propose a framework named SISA training that expedites the unlearning process by strategically limiting the influence of a data point in the training procedure. David E Rumelhart, Geoffrey E Hinton, and Ronald J Williams. This paper introduces concept of Membership Inference Attacks Against Machine Learning Models.. In this paper, we present the first membership inference attack against black-boxed object detection models that determines whether given data records are used in training. We have shown above that the membership inference attack can be effective against a model trained with RDP at \(\epsilon = 1000\). You can find more details in first paper about this topic — “ Membership Inference Attacks Against Machine Learning Models ” We quantitatively investigate how machine learning models leak information about the individual data records on which they were trained. A good machine learning model is one that not only classifies its training data but generalizes its capabilities to examples it hasn’t seen before. Technical Report Attribute inference (guessing a type of data) and membership inference (particular data examples) are vital not only due to privacy issues but also as an exploratory phase for Evasion attacks. Machine Unlearning If our data is used to train a Machine Learning model, we always have the right to revoke the access and requesting the model to unlearn our data. The Internet Society. One major attack in this field is membership inference the goal of which is to determine whether a data sample is part of the … To perform membership inference against a target model, we make adversarial use of machine learning and train our own inference model to recognize differences in the target model's predictions on the inputs that it trained on versus the inputs that it did not train on. Machine learning models have been shown to be susceptible to several privacy attack that target the inputs or the model parameters, such as membership inference, attribute inference, model stealing [52] and model inversion [11]. The privacy risks of machine learning models can be evaluated as the accuracy of such inference attacks against … Membership inference attacks are further studied in [11], which concludes that membership disclosure exists widely, not only in overfitting models, but also in well-generalized models. Hardening against membership inference could prevent a researcher from determining whether a given person was included, which can be useful for efforts at machine learning accountability or determining the source of images for dataset training. Next to membership inference attacks, and attribute inference attacks, the framework also offers an implementation of model inversion attacks from the Fredrikson paper. This goal can be achieved with the right architecture and enough training data. This goal can be achieved with the right architecture and enough training data. (2015)], [Backes et al. Logistic Regression over Encrypted Data from Fully Homomorphic Encryption. ART v1.4 introduces these attacks to provide developers and researchers with the tools required for evaluating the robustness of ML models against these inference attacks. In 26th Annual Network and Distributed System Security Symposium, NDSS 2019. Finally attack model can be trained with predictions from shadow models and test on the target model. The general idea behind this attack is to use multiple machine learning models (one for each prediction class), referred to as attack models, to make membership inference over the target model’s output, i.e., posterior probabilities. Defense methods which use differential privacy mechanisms or adversarial training cannot handle the trade-off between privacy and utility well. In this paper we mainly focus on membership and attribute inference attacks. Membership inference (MI) is a type of attack in which the adversary tries to rebuild the records used to train the model. (2016)] on Machine Learning Models “Exposed! [35].Indeed, discriminative models attempt to predict a label given a data input, and so an attacker performing membership inference on such a model will glean pertinent information, such as the confidence the model places … [ ] introduce the membership inference attacks, which refer to a class of attack models that predict whether a given data sample was present in the training data for a trained model. Published: February 11, 2019 How to attack a model. Background. 1986. We About Code for Membership Inference Attack against Machine Learning Models (in … Our technical report titled "Dynamic Backdoor Attacks Against Machine Learning Models" is now online; Our paper "Updates-Leak: Data Set Inference and Reconstruction Attacks in Online Learning" got accepted in USENIX 2020! Index Terms—epigenetics, membership inference 1. Membership inference attacks were first described by Shokri et al. It has been shown that machine learning models can be attacked to infer the membership status of their training data. Membership Inference attacks against machine learning models The secret sharer: Measuring unintended neural network memorization & extracting secrets Deep Models Under the GAN: Information Leakage from Collaborative Deep Learning Dynamic Backdoor Attacks Against Machine Learning Models. In this setting, there are mainly two broad categories of inference attacks: membership inference and property inference attacks. But a type of attack called “membership inference” makes it possible to detect the data used to train a machine learning model. (2008)], [Dwork et al. The new membership inference attacks of ART v1.4 allow reproducing a malicious attacker attempting to determine if the information of a certain record, e.g. attack against machine learning models. • Membership inference: Given a model, can an adversary infer whether data point x is part of its training set? Moreover, we do not investigate “white box” 47 There exists an extensive body of literature on membership inference attacks against supervised 48 machine learning models [12, 11, 16].
