Project description
Making sure our private data stays private
Our browsing history is not private. Massive amounts of data are being collected by internet giants. EU data protection rules, however, guarantee the protection of our personal data whenever these are collected. To enhance privacy in the digital era, the EU-funded PRIMAL project will speed up secure computation in practice. Its first task will be private classification (where one party holds a model trained on a sensitive data set and another holds a sample and wishes to evaluate the model on that private sample). The second task covers federated learning that enables thousands of participants to train a neural network on joint data. Specifically, the project will improve specific cryptographic building blocks and apply them for these applications.
Objective
Machine learning algorithms are data-hungry, and perform better when exposed to more and more data. Such data is being collected in massive amounts by internet giants, and is often sensitive and private. Examples include the purchases and browsing history of users, their health data and exercise activity, locations they travel to and messages they type into their mobile phone. The amount of data being collected can be significantly reduced using cryptographic techniques, in particular, using secure multiparty computation. Secure computation enables mutually distrustful parties to compute a joint function of their inputs without revealing the inputs to one another.
In this research, we will address secure computation techniques of machine learning tasks. The first task is private classification: One party holds a model trained on a sensitive dataset, and another party holds a sample and wishes to evaluate the model on that private sample. Our objective is to fulfill this task while achieving significantly stronger security notion than previous works, that is, security even if one of the parties deviates from the protocol specifications (malicious security). The second task is federated learning, a techniques that enables thousands of participants to train a neural network on their joint data but without revealing the data to one another. However, a recent work showed that such task is susceptible to injection of backdoors, and a user can manipulate the joint model to his/her own benefit, significantly reducing the usefulness of federated learning in practice. Our objective is to guarantee immunity to such injections. The two objectives will be achieved by improving specific cryptographic building blocks, and applying them for these applications.
PRIMAL will speed up secure computation in practice, and carries immense potential to enhance privacy in the digital era.

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
