ACCOUNT AUTHENTICATION USING HANDWRITING SAMPLES

In some implementations, a device may obtain registration information, associated with an account, including one or more training handwriting samples of a user. The device may detect an initiation of an event associated with the account. The device may provide, to a terminal device associated with the event, the one or more authentication prompts to cause the terminal device to provide the one or more authentication prompts while the event is pending. The device may obtain, from the terminal device, one or more handwriting samples in response to the one or more authentication prompts. The device may determine, using a machine learning model, whether the user is associated with the event based on whether the one or more handwriting samples are in a handwriting of the user. The device may authenticate the event based on determining whether the one or more handwriting samples are in the handwriting of the user.
