System and method of electroencephalography (eeg) continuous authentication and mental and synchrony assessments

A head worn apparatus used for authentication during a login process using electroencephalography (EEG) signals, comprising:

• one or more EEG sensors;
• one or more processors;
• a memory coupled to the one or more processors and the one or more EEG sensors, the memory containing computer instructions which when executed causes the one or more processors to perform the steps at the head worn apparatus of:
• collecting EEG data from the one or more EEG sensors upon recognizing a user identity as an input for access to a secure computer resource;
• initiating an EEG authentication process with an access management and authentication service (STA) via a Brain Computer Interface (BCI) server in communication with a BCI Authentication module upon detecting the user identity and the EEG data;
• sending the EEG data to the BCI Authentication module via the BCI server;
• continuing to capture and sending the EEG data in a background process to the BCI server after an initial successful authentication and logon to perform a personalized mental state assessment based on EEG features of the EEG data collected, wherein the personalized mental state assessment is performed continually;
• and
• continuing to receive access to the secure computer resources while no degraded mental state is detected beyond a threshold value.

The head worn apparatus of claim 13, wherein the one or more processors are further configured to perform a synchrony assessment based on EEG features of the EEG data collected from the one or more sensors from a claimed identity associated with the user identity and from one or more sensors for at least a second claimed identity in team collaboration with the claimed identity based on a hyperscanning methodology that captures EEG signals from multiple claimed identities simultaneously 14. A method for authentication during a login process using electroencephalography (EEG) signals, comprising:

• collecting EEG data from one or more sensors for a claimed identity;
• initiating an EEG authentication process comparing the EEG data with a stored model of the claimed identity;
• granting authentication and access to the claimed identity to a secure computer resource if the EEG data match at or above a threshold value with the stored model of the claimed identity;
• maintaining authentication and access by continuous skin-contact monitoring based on a threshold crossing detection, wherein access to the secure computer resources remains while no threshold crossing is detected;
• performing a personalized mental state assessment based on EEG features of the EEG data collected, wherein the personalized mental state assessment is performed continually;
• continuing to grant access to the secure computer resources while no degraded mental state is detected beyond a threshold value;
• and
• performing a synchrony assessment based on EEG features of the EEG data collected from one or more sensors from the claimed identity and from one or more sensors for at least a second claimed identity in team collaboration with the claimed identity, wherein the synchrony assessment is based on a hyperscanning methodology that captures EEG signals from multiple claimed identities simultaneously.
