1. Srinivasan, Srivats. Human or bot.

Degree: MS, Computer Science, 2017, California State University – Sacramento

Online auctions have become an increasingly important aspect of e-commerce. The major problem with online bidding/auctioning is that there is no way of identifying if the user is a human or a bot. Human bidders are becoming increasingly frustrated with their inability to win auctions against their software-controlled counterparts. Bidding robots such as ???Ez Sniper??? and ???Auction Sniper??? are pieces of software that are configured by users to follow any number of auctions on different auction sites simultaneously, bidding in place of the user according to predefined settings and preferences. Humans are not able to attend to and monitor auctions with the same capacity as a running program, which can make complex bidding decisions in splitsecond time and can follow an auction with nonstop, undivided attention. As a result, usage from the site's core customer base is plummeting. To rebuild customer happiness, the auction service providers need to eliminate computer generated bidding from their auctions. This project aims to address this problem by providing a solution to identify bids that are placed by bidding bots. The identification is achieved by using machine learning techniques, such as Random Forest and Decision Tree, and uses several key features extracted from online bidding data, such as time, country, IP address, etc. The application provides three major functionalities as follows, CreateTrainingData, CreateModel, and Identify. In the absence of existing training data, CreateTrainingData creates training data with the help of the built-in model. The created data is to be verified. Once done so it would be used in the CreateModel function. CreateModel function creates a model based on the existing/created training data and its extracted features. The created model would be used for the identification process. The Identify function identifies the user/set of users whom uses bidding bots based on the model created. The application also provides some security protection by preventing SQL injection attacks. The 1st order and 2nd order SQL injection attacks are detected and prevented from execution. The application can receive input values and SQL statement as JSON value. The input values are first checked for special character if found, then the received SQL statement is split on input values and checked for SQL injection vulnerabilities.
