Systems and methods for authenticating user identity based on user defined image data

A computer-implemented method, comprising:

• generating, using at least one processor, an electronic command to display first digital image data on a touchscreen display unit of a device, the first digital image data identifying at least a portion of a first reference face of a user;
• identifying, using at least one processor, pixels of the displayed first digital image data that correspond to features of the first reference face;
• generating, using at least one processor, mapping data that maps the identified pixels and the corresponding features to spatial positions on a surface of the touchscreen display unit;
• receiving, using the at least one processor, authentication information from the touchscreen display unit, the authentication information identifying a temporal sequence of contact positions detected along the surface of the touchscreen display unit;
• based on the authentication information and the generated mapping data, identifying, using the at least one processor, and detected along the surface of the touchscreen the features of the first reference face that correspond to the temporal sequence of the contact positions, and based on the identified features, establishing, using the at least one processor, a sequential selection of the features of the first reference face selected by the user, the sequential selection of the features establishing a candidate selection sequence of the features for the first reference face;
• authenticating, using the at least one processor, an identity of the user when the candidate selection sequence of the features corresponds to a first authentication sequence or a second authentication sequence, the first authentication sequence being associated with a device functionality that is accessible to the user, and the second authentication sequence being associated with an executable application that is accessible to the user;
• and
• using the at least one processor, performing operations that modify an operational state of the device in accordance with at least one of (i) the accessible device functionality or (ii) an additional device functionality associated with the accessible executable application.

A tangible, non-transitory computer-readable medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform a method, comprising:

• generating an electronic command to display first digital image data on a touchscreen display unit of a device, the first digital image data identifying at least a portion of a first reference face of a user;
• identifying pixels of the displayed first digital image data that correspond to features of the first reference face;
• generating mapping data that maps the identified pixels and the corresponding features to spatial positions on a surface of the touchscreen display unit;
• receiving authentication information from the touchscreen display unit, the authentication information identifying a temporal sequence of contact positions detected along the surface of the touchscreen display unit;
• based on the authentication information and the generated mapping data, identifying the features of the first reference face detected along the surface of the touchscreen that correspond to the temporal sequence of the contact positions, and based on the identified features, establishing a sequential selection of the features of the first reference face selected by the user, the sequential selection of the features establishing a candidate selection sequence of the features for the first reference face;
• authenticating an identity of the user when the candidate selection sequence of the features corresponds to a first authentication sequence or a second authentication sequence, the first authentication sequence being associated with a device functionality that is accessible to the user, and the second authentication sequence being associated with an executable application that is accessible to the user;
• and
• performing operations that modify an operational state of the device in accordance with at least one of (i) the accessible device functionality or (ii) an additional device functionality associated with the accessible executable application.
