Abstract: Techniques for using a graphical user interface to automatically generate expense lines from images are described herein. According to an embodiment, a server computer causes storing in a data repository, data identifying a plurality of users, the data comprising feature data extracted from one or more images of the users. The server computer receives a digital photographic image captured using a camera in a mobile computing device. The server computer identifies one or more faces in the digital photographic image and determines that the one or more faces in the digital photographic image match a particular user. The server computer generates and stores an expense line in an expense data table in the data repository, the expense line comprising an identification of the particular user.

Abstract: A method and system of trading derivatives of various items includes an electronic marketplace configured to accept requests to purchase derivatives and requests to sell derivatives. The marketplace is configured to match requests to purchase with requests to sell when certain criteria are similar to within predetermined limits. Available derivatives include futures contracts, put options, and call options. The derivatives allow one to purchase rights in an item prior to the actual delivery of the item. In addition, the derivatives may be traded to other parties. The use of such derivatives also enables entities to negotiate the prices for various goods and services that were previously not readily negotiable in the past.
