Abstract: A virtual payments environment can be used to simulate and test performance of a payments system. A plurality of characteristics and settings can be used to generate and/or determine one or more scenarios associated with a payments environment. The one or more scenarios associated with the payments environment can comprise a plurality of activity engines that simulate real-word components of a payments environment. Payment information can be introduced to the one or more scenarios and activity engines can be used to test and/or verify the integrity of the payment information as it traverses a transactional path through the payments environment. Performance data associated with the payment information can be accessed and review in order to determine a number or successes and/or failures associated with processing the payment information as it transverses the payments environment.

Abstract: Disclosed are methods and systems for user authentication. User-specific data is aggregated by an authentication system. Answers to authentication questions are identified in the aggregated data. A user device attempting to authenticate with the authentication system is presented with the authentication question and selectable options for answering the authentication question. The selectable options include one or more valid answers and one or more false answers. A user device is authenticated after correctly answering one or more presented authentication questions.

Abstract: A time estimation method and system. The method comprises performing a loop of one or more iterations. Each iteration is for calculating a remaining time duration (RD) for completing a process for performing tasks. The loop is performed until the RD equals zero. Each iteration comprises receiving first data related to a plurality of objects associated with the process. A time to complete each object of the plurality of objects (POT) is calculated based on the first data. A number of objects of the plurality of objects remaining in the process (OR) is calculated based on the first data. Second data related to a plurality of work units is received. The plurality of work units is comprised by the plurality of objects. Each work unit is associated with a different task of the tasks. The RD is calculated based on the POT, the OR, and the second data.
