Continuous authentication system and method based on BioAura
First Claim
1. A system for continuous authentication of a user of an electronic device for use with a plurality of wireless wearable medical sensors (WMSs) and a wireless base station configured to receive a biomedical data stream (biostream) from each of the plurality of WMSs, the biostream from a single WMS lacking enough discriminatory power to distinguish the user, the system comprising:
- a BioAura engine located on a server, the server having one or more receive buffers configured to store a preprocessed plurality of biostreams, the BioAura engine being configured to;
transmit the preprocessed plurality of biostreams to a classifier particular to a user of the electronic device via a look up stage; and
generate an authentication output to authenticate the user'"'"'s access to the electronic device based on whether the preprocessed plurality of biostreams matches a trained model of the user'"'"'s plurality of biostreams via the classifier particular to the user, the trained model based on an initial training dataset comprising multi-dimensional data points containing average values of successive measurements of the retrieved biostreams over a specified time interval, the trained model being periodically updated with subsequent training datasets each comprising multi-dimensional data points containing average values of successive measurements of the retrieved biostreams over a specified time interval;
the wireless base station having a communication engine configured to;
retrieve the biostream from each WMS;
preprocess the retrieved biostreams by creating a multi-dimensional data point containing average values of the retrieved biostreams over a specified time interval; and
transmit the preprocessed plurality of biostreams to the server.

Abstract
A user authentication system for an electronic device for use with a plurality of wireless wearable medical sensors (WMSs) and a wireless base station that receives a biomedical data stream (biostream) from each WMS. The system includes a BioAura engine located on a server, the server has a wireless transmitter/receiver with receive buffers that store the plurality of biostreams, the BioAura engine has a look up stage and a classifier, the classifier generates an authentication output based on the plurality of biostreams, the authentication output authenticates the user'"'"'s access to the electronic device. The wireless base station has a transmitter/receiver having receive buffers that store the biomedical data from each WMS, the wireless base station has a communication engine that retrieves the biostream from each WMS and transmits the plurality of biostreams to the server.
