cs.CR updates on arXiv.org arxiv.org
Our behavior (the way we talk, walk, act or think) is unique and can be used
as a biometric trait. It also correlates with sensitive attributes like
emotions and health conditions. Hence, techniques to protect individuals
privacy against unwanted inferences are required, if such data is planned to be
