During registration, a mobile communication device derives a first instance of biometric information from a user operating the mobile communication device. The communication device retrieves an encryption key assigned to the mobile communication device. Via application of the encryption key to the first instance of biometric information, the communication device produces first encrypted biometric information and forwards it to an authentication resource. The authentication resource stores the first encrypted biometric information for later authentication of the communication device. During subsequent authentication, the mobile communication device derives a second instance of biometric information from the user operating the mobile communication device. The communication device encrypts the second instance of biometric information with the encryption key and forwards it to the authentication resource. The authentication resource requires a substantial match of the second encrypted biometric information to the first encrypted biometric information to authenticate the communication device to use a wireless network.

A computer-implemented system, method, and non-transitory medium for detecting cognitive inception risk and generating defensive interventions. The Cognitive Inception Detection and Defense System (CIDDS) receives a time-stamped content exposure stream associated with a user and user cognitive output signals (e.g., text, speech, selections, interaction events). CIDDS projects exposure and output signals into a multidimensional semantic vector space; maintains a stateful, decay-weighted baseline for the user; computes (i) a Baseline Deviation Index (BDI) and (ii) an Inception Propensity Score (IPS) derived from structural properties of exposures (e.g., priming sequences, repetition structure, microtargeting indicators, synthetic consensus indicators). CIDDS fuses these measures to generate a Cognitive Origin Authentication Score (COAS) and an interpretable origin assessment. Responsive to a confidence score satisfying a triggering condition, CIDDS outputs defensive actions including alerting, reflection prompting, exposure throttling, quarantine, blocking, or escalation, while maintaining tamper-evident audit logs. Optional embodiments incorporate non-invasive neurophysiological signals (e.g., EEG).
