Abstract: Described are methods and systems for detecting fraud in documents. First images of a first set of genuine documents and second images of a second set of genuine documents are obtained. A printed feature, spacings between printed features in the first images, and positions of printed features in the second images are selected. Selected features, spacings and positions are annotated to obtain original landmark locations for each printed feature, spacing and position. Annotated features, spacings and positions are transformed to obtain transformed features, transformed spacings and transformed positions. The transformed features, spacings and positions are combined with a noise model to generate modified features, modified spacings and modified positions. Each modified feature, modified spacing and modified position comprises annotations indicating modified landmark locations. Input data for a machine learning model is generated using original landmark locations and modified landmark locations.

Abstract: A system may include an application server and a user device. The application server may host an application customized for the user device. Tests may be designed to check the functionality of the application at the user device. The application and test may be designed using a page objects library which improve durability of the application and tests to changes made to the application. Thus, even if changes are made to the application, the test which check the functionality of the application may not break if the application and the tests are created based on the page objects library. The application sever may generate the page objects library and distribute the page objects library to its tenants.
