TECHNICAL FIELD

The present disclosure relates to computer-implemented methods, software, and systems for expense report auditing.

BACKGROUND

Travel and travel-related expenses can be a large expense for organizations. An automated expense management system can be used to analyze, monitor, and control travel and other reimbursable expenses, while maintaining accuracy and increasing worker productivity. An automated expense management system can enable employees to spend less time creating and monitoring expense reports, which can allows workers to spend more time on core job functions.

SUMMARY

The present disclosure involves systems, software, and computer implemented methods for expense report auditing. One example method includes: identifying a first corpus of valid reference images; identifying a second corpus of fraudulent reference images; analyzing first pixel values of first pixels in the valid reference images in the first corpus to determine at least one valid pixel-based pattern that is included in at least a first threshold percentage of the valid reference images; analyzing second pixel values of second pixels in the fraudulent reference images in the second corpus to determine at least one fraudulent pixel-based pattern that is included in at least a second threshold percentage of the fraudulent reference images; receiving a request to classify a first image; analyzing third pixel values of third pixels included in the first image; determining whether the third pixel values match either a valid pixel-based pattern or a fraudulent pixel-based pattern; in response to determining that the third pixel values match a valid pixel-based pattern, increasing a first likelihood of classifying the first image as a valid image; in response to determining that the third pixel values match a fraudulent pixel-based pattern, increasing a second likelihood that the first image as a fraudulent image; and classifying the first image in response to the request as either a valid image or a fraudulent image based on the first likelihood and the second likelihood

While generally described as computer-implemented software embodied on tangible media that processes and transforms the respective data, some or all of the aspects may be computer-implemented methods or further included in respective systems or other devices for performing this described functionality. The details of these and other aspects and embodiments of the present disclosure are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of the disclosure will be apparent from the description and drawings, and from the claims.
