Electronic profile and data security enforcement with user device data and methods of use thereof
Systems and methods of the present disclosure include computer systems for improving data security. To do so, an authorization request associated with a user profile is received, including a time-stamp for a profile activity, a profile identifier, and a value. Application analytics data for a software application on a user device associated with the user profile is accessed, including an open event indicator indicating a time of a loading, and a close event indicator indicating a time of a termination. An open period of the software application at the time-stamp is determined based on the application open event indicator and the application close event indicator. A reduced set of fraud checks is selected and executed when the time-stamp associated with the profile activity is within the open period of the software application. A fraud determination is generated, and an authorization notification is generated based on the fraud determination. |

Methods and systems for generating a unique signature based on user movements in a three-dimensional space
Systems and methods are disclosed for movement-based signature authentication. One method comprises determining one or more features associated with a user based on one or more two-dimensional images and determining one or more body points associated with the user based on one or more three-dimensional images. A movement pattern of each body point of the user is determined based on the one or more three-dimensional images. The one or more determined features are compared to corresponding one or more stored features associated with the user. If the one or more detected features match the one or more stored features, the one or more determined movement patterns are compared to a unique electronic signature associated with the user. Upon determining that the one or more determined movement patterns match the unique electronic signature, the user is authenticated for electronic transaction. |

Techniques for processing pin-inclusive transactions in connection with an electronic device
Certain exemplary embodiments relate to techniques for processing PIN-inclusive transactions in connection with an electronic device or terminal, e.g., where PIN code encryption keys are not necessarily stored on the electronic device or terminal, and/or where payment instrument data is maintained in a separate system from PIN code data at least until certain elements are combined in a highly secure system for submission to an electronic funds transfer network. One or more separate or physically separated systems may be used in this regard, e.g., taking advantage of more prevalent computer networks such as the Internet. Similarly, the ability to provide less expensive terminals or electronic devices at a point-of-sale, point-of-purchase, etc., may be advantageous. The interchange rate is not necessarily driven up in certain example instances. |
