Biometric reader with micro-electromechanical system (MEMS) components

A method comprising:

• detecting one or more points of contact of a finger of a user with a subset of portions of a plurality of portions of a surface of a device;
• identifying a first subset of MEMS components of a plurality of MEMS components that correspond to the subset of portions of the surface of the device, wherein each respective MEMS component of the plurality of MEMS components is configured to actuate to cause one or more portions of the surface of the device to move;
• causing the first subset of MEMS components to actuate based at least in part on detecting the one or more points of contact of the finger with the subset of portions of the surface of the device;
• measuring, using positions of the first subset of MEMS components, topography of the finger;
• detecting a fingerprint profile of the user based at least in part on the measured topography of the finger;
• determining whether the fingerprint profile corresponds to a registered fingerprint profile;
• detecting one or more points of contact of the finger with one or more adjacent subsets of portions of the plurality of portions of the surface of the device;
• identifying one or more second subsets of MEMS components of the plurality of MEMS components that correspond to one or more edge portions of the one or more adjacent subsets of portions of the surface of the device;
• using the one or more second subsets of MEMS components to detect a gesture profile;
• determining whether the gesture profile corresponds to a registered movement;
• and
• authenticating the user based at least in part on determining that the fingerprint profile corresponds to the registered fingerprint profile and that the gesture profile corresponds to the registered movement.

A non-transitory computer readable medium having instructions encoded thereon that, when executed by control circuitry, cause the control circuitry to:

• detect one or more points of contact of a finger of a user with a subset of portions of a plurality of portions of a surface of a device;
• identify a first subset of MEMS components of a plurality of MEMS components that correspond to the subset of portions of the surface of the device, wherein each respective MEMS component of the plurality of MEMS components is configured to actuate to cause one or more portions of the surface of the device to move;
• cause the first subset of MEMS components to actuate based at least in part on detecting the one or more points of contact of the finger with the subset of portions of the surface of the device;
• measure, using positions of the first subset of MEMS components, topography of the finger;
• detect a fingerprint profile of the user based at least in part on the measured topography of the finger;
• determine whether the fingerprint profile corresponds to a registered fingerprint profile;
• detect one or more points of contact of the finger with one or more adjacent subsets of portions of the plurality of portions of the surface of the device;
• identify one or more second subsets of MEMS components of the plurality of MEMS components that correspond to one or more edge portions of the one or more adjacent subsets of portions of the surface of the device;
• use the one or more second subsets of MEMS components to detect a gesture profile;
