Inverting Gradients - How easy is it to break privacy in federated learning?

  title={Inverting Gradients - How easy is it to break privacy in federated learning?},
  author={Jonas Geiping and Hartmut Bauermeister and Hannah Dr{\"o}ge and Michael Moeller},
The idea of federated learning is to collaboratively train a neural network on a server. Each user receives the current weights of the network and in turns sends parameter updates (gradients) based on local data. This protocol has been designed not only to train neural networks data-efficiently, but also to provide privacy benefits for users, as their input data remains on device and only parameter gradients are shared. But how secure is sharing parameter gradients? Previous attacks have… 
Inhibition of Na-K-ATPase in thick ascending limbs by NO depends on O2- and is diminished by a high-salt diet.
It is concluded that NO inhibits Na-K-ATPase after long exposures when rats are on a normal diet and this inhibition depends on O(2)(-).
The implicit set paradigm: A new approach to finite state system verification
This paper presents a new state of the art in the field of finite state system verification by using an implicit representation of these systems in an implicit, way to overcome the limitations of previously availble techniques.
Can denial of pregnancy be a denial of fertility? A case discussion.
It appears that a specific personality profile is very difficult to establish in women who have had a denial of pregnancy, due to the lack of sufficient data and the discrepancy of the results concerning these women, especially in the matters of age and socio-economic status.
Data Leakage in Federated Averaging
A new optimization-based attack is proposed which successfully attacks FedAvg by solving the optimization problem using automatic differentiation that forces a simulation of the client’s update that generates the unobserved parameters for the recovered labels and inputs to match the received client update.
Gradient Obfuscation Gives a False Sense of Security in Federated Learning
It is shown that commonly adopted gradient postprocessing procedures, such as gradient quantization, gradient sparsification, and gradient perturbation, may give a false sense of security in federated learning and argued that privacy enhancement should not be treated as a byproduct of gradient compression.
AGIC: Approximate Gradient Inversion Attack on Federated Learning
AGIC approximates gradient updates of used training samples from model updates to avoid costly simulation procedures, leverages gradient/model updates collected from multiple epochs, and assigns increasing weights to layers with respect to the neural network structure for reconstruction quality.
Auditing Privacy Defenses in Federated Learning via Generative Gradient Leakage
This work validate that the private training data can still be leaked under certain defense settings with a new type of leakage, i.e., Generative Gradient Leakage (GGL), and leverages the latent space of generative adversarial networks learned from public image datasets as a prior to compensate for the informational loss during gradient degradation.
PRECODE - A Generic Model Extension to Prevent Deep Gradient Leakage
This paper introduces PRECODE, a PRivacy EnhanCing mODulE that can be used as generic extension for arbitrary model architectures that effectively prevents privacy leakage from gradients and in turn preserves privacy of data owners using variational modeling.
A Method to Reveal Speaker Identity in Distributed ASR Training, and How to Counter IT
This work designs Hessian-Free Gradients Matching, an input reconstruction technique that operates without second derivatives of the loss function (required in prior works), which can be expensive to compute.
Evaluating Gradient Inversion Attacks and Defenses in Federated Learning
This paper evaluates existing attacks and defenses against gradient inversion attacks, and suggests that the state-of-the-art attacks can currently be defended against with minor data utility loss.


Poxviral Disease in Red Squirrels Sciurus vulgaris in the UK: Spatial and Temporal Trends of an Emerging Threat
Eight juvenile and sub-adult free-living red squirrels apparently survived exposure to SQPV by mounting an immune response, the first evidence of immunity to SQpV in free- living red squirrelS, which possibly suggests a changing host-parasite relationship and that the use of a vaccine may be an effective management tool to protect remnant red squirrel populations.
Human adhalin is alternatively spliced and the gene is located on chromosome 17 q 21 ( musular dystrophy / dystrophin / dystrophn-ated protein )
Genetic analyses of patients with Duchenne and Becker muscular dystrophy have demonstrated a correlation between mutations in dystrophin's carboxyl terminus and a more severe clinical course, and one potential role of the dystrophic-glycoprotein complex as a bridge between the cytoskeleton, sarcolemma, and extracellular matrix is identified.
Persuasive negotiation for autonomous agents: A rhetorical approach
Persuasive negotiation occurs when autonomous agents exchange proposals that are backed up by rhetorical arguments (such as threats, rewards, or appeals). The role of such rhetorical arguments is to
Selection algorithms for replicated Web servers
Two new algorithms for selection of replicated servers are designed and it is shown that the new server selection algorithms improve the performance of other existing algorithms on the average by 55% and the existing non-replicated Web servers on average by 69%.
Deep Leakage from Gradients
This work shows that it is possible to obtain the private training data from the publicly shared gradients, and names this leakage as Deep Leakage from Gradient and empirically validate the effectiveness on both computer vision and natural language processing tasks.
Deep Residual Learning for Image Recognition
This work presents a residual learning framework to ease the training of networks that are substantially deeper than those used previously, and provides comprehensive empirical evidence showing that these residual networks are easier to optimize, and can gain accuracy from considerably increased depth.
iDLG: Improved Deep Leakage from Gradients
This paper finds that sharing gradients definitely leaks the ground-truth labels and proposes a simple but reliable approach to extract accurate data from the gradients, which is valid for any differentiable model trained with cross-entropy loss over one-hot labels and is named Improved DLG (iDLG).
Beyond Inferring Class Representatives: User-Level Privacy Leakage From Federated Learning
This paper gives the first attempt to explore user-level privacy leakage against the federated learning by the attack from a malicious server with a framework incorporating GAN with a multi-task discriminator, which simultaneously discriminates category, reality, and client identity of input samples.
