Abstract
Identifying and protecting against a computer security threat while preserving privacy of individual client devices using differential privacy for text documents. In some embodiments, a method may include receiving, at the remote server device, text documents from one or more local client devices, generating, at the remote server device, a differential privacy document vector for each of the text documents, identifying, at the remote server device, a computer security threat to a first one of the one or more local client devices using the differential privacy document vectors, and, in response to identifying the computer security threat, protecting against the computer security threat by directing performance, at the first local client device or the remote server device, of a remedial action to protect the first local client device from the computer security threat.
