Abstract: Methods and systems described herein recite the use of specific data structures for stateful data that include fields for populating with specific information that may be used to prevent and/or minimize the corruption in stateful data. The systems and methods may recite the application of specific data normalization sets that include functions to be applied to test data sets and control data sets, respectively, in order to prevent and/or minimize the corruption. Finally, the methods and systems may recite the determination of incrementality being based on uncorrupted impressions corresponding to test data sets and control data sets, respectively.

Abstract: The present disclosure relates to systems and methods for implementing tiered authentication using position-based credentials. A system for authenticating a user with position-based credentials may include one or more memories storing instructions and one or more processors configured to execute the instructions to perform operations. The operations may include receiving a login request associated with the user from a first user interface device; receiving a first location associated with the first user interface device; receiving a second location associated with a second user interface device; when a Lebesgue distance between the first location and the second location is below a first threshold, authenticating the user; when the Lebesgue distance is above the first threshold and below a second, larger threshold, prompting the first interface device for a first credential; and when the Lebesgue distance is above the second threshold, prompting the first interface device for a second credential.

Abstract: A system and method for performing a purchase transaction using rewards points by receiving a purchase request using a financial account with associated account information, determining based on the account information that the financial account is associated with a rewards program with rewards points, and providing the option to pay for the purchase using the financial account or at least a portion of the rewards points. The purchase may be paid for using rewards points from multiple rewards programs and/or multiple financial accounts.
