Abstract

In some implementations, a device may receive, from a user device, a login request to access an account associated with a user. The device may determine device metadata relating to a use of the user device in connection with the login request. The device may determine whether the use is recognized for the user based on the device metadata. The device may cause, responsive to a determination that the use is not recognized for the user, the user device to provide a prompt for inputting a handwriting sample. The device may determine input metadata relating to an inputting of the handwriting sample. The device may determine whether the handwriting sample is valid for the user based on the input metadata and an image of the handwriting sample. The device may authorize the login request responsive to a determination that the handwriting sample is valid for the user.

Claims20

Dependent claims

A system for device-independent user authentication, the system comprising:

one or more memories;
and
one or more processors, communicatively coupled to the one or more memories, configured to:
receive, from a user device, a login request to access an account associated with a user;
determine device metadata relating to a use of the user device in connection with the login request,
wherein the device metadata includes one or more of:
an orientation of the user device, a touch pressure of inputs to the user device, or a typing speed on the user device;
determine, using a first user-specific machine learning model, whether the use is recognized for the user based on the device metadata;
cause, responsive to a determination that the use is not recognized for the user, the user device to provide a prompt for inputting a handwriting sample;
determine input metadata relating to an inputting of the handwriting sample,
wherein the input metadata includes one or more of:
an input pressure used for the handwriting sample or an input speed used for the handwriting sample;
determine, using a second user-specific machine learning model, whether the handwriting sample is valid for the user based on the input metadata and an image of the handwriting sample;
and
authorize the login request responsive to a determination that the handwriting sample is valid for the user.

12 more elements

A non-transitory computer-readable medium storing a set of instructions for device-independent user authentication, the set of instructions comprising:

one or more instructions that, when executed by one or more processors of a device, cause the device to:
determine device metadata relating to a use of a user device;
determine whether the use is recognized based on the device metadata;
cause, responsive to a determination that the use is not recognized, the user device to provide a prompt for inputting a handwriting sample;
determine input metadata relating to an inputting of the handwriting sample;
and
determine whether the handwriting sample is valid based on the input metadata and an image of the handwriting sample.
