Abstract: A method for generating synthetic behavior samples with a behavior generator includes drawing, at the behavior generator, a vector from a probability distribution obtained from behavior data of a plurality of users. The method also includes generating, with an artificial neural network decoder of the behavior generator, a synthetic behavior sample based on the vector. The method further includes tuning a model, which identifies a device user, using the generated synthetic behavior sample.

Abstract: A method of authenticating a user on a mobile device includes gathering samples of behavioral data of the user from multiple sensors of the mobile device, each sensor generating a different number of samples. The method also includes normalizing the samples to have a same number of samples for each sensor. The method further includes extracting, with a convolutional neural network, features from the normalized samples and authenticating the user based on the extracted features.
