Biometric System Disruption Eyeglasses Frames And Methods

A wearable eyewear device for disrupting biometric image capture, comprising:

• (a) a frame configured in an eyewear form factor, the frame comprising a bridge, lens rims, and temple arms;
• (b) a plurality of infrared emitters embedded in and distributed around said frame, wherein said plurality comprises at least sixteen emitters and not more than thirty-two emitters, said emitters being located at the bridge, along lower rim portions adjacent to the cheeks, at frontal portions of the temples, and at rearward portions of the temple arms to provide wrap-around coverage of a wearer's face;
• (c) each infrared emitter configured to emit light within a spectral band between about 780 nm and about 1100 nm, a controller operatively coupled to the emitters and configured to selectively activate subsets of emitters in randomized or sensor-responsive patterns, including variations in duty cycle, pulse width, and sequence, to prevent machine-learning reconstruction of facial features;
• (d) a power subsystem operatively coupled to the frame, the power subsystem comprising at least one of:
• an integrated power source within the frame, or an external power source coupled through a connector at a temple arm, enabling higher sustained output for daylight operation;
• (e) a thermal management feature integrated into the frame, including one or more ventilation slots or equivalent structures to dissipate heat generated by the plurality of emitters;
• (f) wherein emission of said plurality of emitters disrupts biometric recognition systems including facial recognition algorithms, by obscuring or distorting image capture of the wearer's facial features under varied lighting conditions, including daylight;
• (g) wherein said emission further disrupts structured-light and time-of-flight depth sensing systems by introducing non-coherent infrared patterns and saturating depth-mapping sensors, thereby corrupting three-dimensional facial feature reconstruction;
• (h) wherein said controller is configured to vary emission timing relative to anticipated rolling-shutter sensor exposures, producing frame-to-frame inconsistencies unrecoverable by temporal averaging algorithms;
• (i) wherein said controller adjusts emitter output to maintain disruption across ambient illuminance levels between at least about 200 lux and about 10,000 lux;
• wherein at least a subset of said emitters are configured to deliver peak radiant power of at least 5 watts per diode, enabling disruption under direct daylight conditions.

A method of disrupting biometric recognition of a wearer, comprising:

• (a) emitting infrared light from a plurality of emitters embedded in an eyewear frame, wherein said plurality comprises at least sixteen emitters distributed at a bridge portion, cheek-adjacent rim portions, frontal temple portions, and rearward temple arm portions of the eyewear frame, to provide wrap-around coverage of the wearer's face;
• (b) emitting said infrared light within a spectral band between about 780 nm and about 1100 nm, corresponding to wavelengths detectable by imaging sensors used in facial recognition systems;
• (c) controlling activation of the emitters with a controller configured to:
• vary activation in randomized or sensor-responsive patterns, modulate duty cycle, pulse width, or sequence of emitters, thereby preventing machine-learning systems from reconstructing the wearer's facial features;
• (d) powering the plurality of emitters via a power subsystem comprising at least one of:
• an integrated power source within the eyewear frame, or an external power source coupled to a connector at a temple arm;
• (e) dissipating heat generated by the emitters using thermal management features integrated into the eyewear frame;
• (f) whereby the emission of said plurality of emitters obscures or distorts biometric recognition systems, including AI-based facial recognition algorithms, across varied lighting conditions including daylight;
• (g) whereby said emission further interferes with structured-light and time-of-flight depth sensing by injecting randomized infrared signals that distort or saturate projected-dot or pulsed-return depth maps;
• (h) wherein controlling activation further comprises varying emission timing relative to rolling-shutter sensor exposures to produce frame-to-frame inconsistencies unrecoverable by temporal averaging algorithms;
• (i) wherein powering and control maintain disruption across ambient illuminance levels between at least about 200 lux and about 10,000 lux;
• (j) wherein said plurality of emitters includes at least a subset configured to deliver peak radiant power of at least about 5 watts per diode.
