Abstract: A method and an apparatus that includes performing a material alteration detection process: sampling the document images based at least in part on account information indicated on the document images; performing image pre-processing on the sampled document images; determining a document type for each image of the sampled document images; for handwritten documents, analyzing the document image using a machine learning (ML) algorithm trained to detect material alterations on handwritten documents; for printed documents, analyzing the document image using a ML algorithm trained to detect material alterations on printed documents; and outputting a fraud probability representation for each analyzed document image; and a signature forgery detection process: obtaining past signatures corresponding to the document images; performing signature image pre-processing; authenticating each signature using the past signatures and a ML algorithm trained to match signatures; outputting a similarity measure; and adjusting the

Abstract: A method for performing actions by a wearable device is provided. The method includes detecting at least one signal indicating a movement of a muscle of the wrist, via an array of biometric sensors exposed through an inner peripheral surface of a substantially circular band of the wearable device, identifying an orientation of the wearable device corresponding to the at least one signal, and providing, based at least in part on the identification, a function corresponding to the orientation of the wearable device. The method further includes detecting, by the wearable device, an absolute orientation of the wearable device using at least one of an inertial sensor and the one or more body sensors. The method further includes dynamically performing an action, by the wearable device, based on a pre-stored mapping of the at least one physiological parameter and the absolute orientation of the wearable device.

Abstract: A method and an electronic device for detecting a gesture performed by a user using a wearable device are provided. The method includes determining a first orientation of the wearable device using at least one inertial sensor; determining an orientation of the wearable device worn on a finger of the user by at least one touch sensor; determining a final orientation of the wearable device using the determined first orientation and the determined orientation of the wearable device; and interpreting at least one user gesture based on the determined first orientation of the wearable device.
