Abstract:- Web services have become an integral part of our day-to-day life including the various advertisements viewed on websites. Revenue is generated by companies through advertisement by selling clicks (known as Pay-Per-Click model). The company is paid for each click performed by the user on link published on the webpage. The clicked link redirects the user to sponsoring companys content. Invalid clicks that are generated either by humans or through a software as a malpractice for earning money is known as click- fraud. Several different time features are combined into a time print. Machine learning is performed for understanding up to what extent the unusual time prints occur in a data for distinguishing invalid clicks and identifying click fraud. The results generated shows that time prints are useful tool for the improvement of the quality of click fraud analysis and increases the overall accuracy of the observations.

According to [1], in the online advertising market, the advertiser takes decision about the investments he would make for the advertising, the advertiser then chooses a rate- plan created by the publisher which is suitable for his fixed budget and submits the advertisement for publishing. The ad network is responsible for contracts and legal matters with a publisher that displays the advertisement and receive a part of payment as a commission depending on the impressions made on the advertisement displayed.

A variety of revenue models are used by the users and the publishers which can attract more customers to them and can help them earn profit as well. One such revenue model which is most commonly seen in the industry is the Pay-Per- Click(PPC) model. According to [2], a fixed amount is paid by advertiser to the publisher for each click made by the user. Click-fraud indulges in malpractices for deceiving the revenue model such as PPC by creating records for false clicking activities on online advertisement. The deceiver may have intentions of creating losses to the advertiser by increasing the false impression so that the advertiser pays

more or he may be the agent of the publisher to increase the profits.

Pay Per Click (PPC) model has been implemented in

  1. which shows that auctions and bidding play a vital role in the advertising economy. This has created opportunities for various IT companies and have boosted their wealth at a very high rate. The model exhibits properties such as a greater relevance and effective conversion rates where keywords are entered by a user for searching a specific advertised product.

    According to [8] the Advertiser is the one who aims to make a business with a profit through product selling by means of online advertising. Promotions can be shown on webpage directly as a part of website or can be added as a pop-up related to an action of a user. The ad-network generates economy by taking payments from the advertiser for the promotion on a website or an application. The creation, development, maintenance and the deployment of the webpage or the application is the responsibility of the publisher. Ad Network behaves like a middle-man between the advertiser and publisher and streamlines the process.

    Click fraud should not only be controlled from the technical point of view, but also involve the issue of integrity. If you want to cheat, no technology can be completely overcome and directly impact its market future. To solve click fraud well, or develop an effective strategy to prevent click fraud, or replace the current bidding ranking with another new business model, the current legislation is not perfect, consideration to make use of laws to strengthen the constraint on click fraud is required. The purpose of the study in [21] is to prevent the click fraud, reduce the harm of click fraud to the Internet, and make efforts to build a healthy and harmonious network.

    This paper has been categorized as follows: Section II gives the overview about the different existing research works and also explains the methodologies used previously. Section III provides an overview to the ideas and concepts

    in the proposed model. Section IV concludes the paper with the observations and scope for future improvements.


    The advertiser may encounter the problem of Online Click Fraud in various ways. With the high increase in the internet usage the rate of click frauds has seen a steep climb over past few years. Multiple approaches for tackling the issues have been put forth by various researchers. The following literature gives a basic descriptive idea about various existing computational methodologies available.


      Machine Learning methods such as time-print and traditional classification model are used in [3]. Click data associated with time to check the behavior of users at particular time is analyzed. In [7] Traffic module, Analysis module, and Calculation module are used to monitor the behavior of user for click fraud detection.

      Pixel cluster used in [8] for transit monitoring cursor movements uses applet or java script to keep track of transit of the cursor, it analysis the cursor movements and determines the confidence level to check whether cursor movements are indicative of fraud. Client-side scripting and

      server-side scripting is performed in [10]. It has click verification website to identify valid and invalid clicks and prevents advertising from getting billed for fraudulent activity.

      Support vector machine (SVM) model are implanted in

      1. where AUC (Area Under Curve) value of proposed algorithm is significantly improved in comparison with ELM and the weighted ELM based method. The investigation on Bot signature, Distribution tests, Scale families and reference curves were used to design Microsoft click filtration system. The design in [21] includes real-time and near real-time components and it also has consistence rapid update capability in fraud detection.

        In [22] JavaScript support and mouse event test were carried out along with browser functionality test and browser behavior examination that collected information about real world click traffic. To perform effective identification of human and bot clicks a vital element is the testing throughout the clients functionality at the advertisers side, which is implemented at both the server as well as client sides incurring negligible overhead. Filtering on Rule based, Classification based and Clustering based are carried over data in [30].

      The analysis in [9] concludes that performance of classification schemes is improved when data is pre- processed by performing feature selection and resampling. Resampling is done using SMOTE and then performing classification using Adaboost with random forest as base classifier which in turn produced the most improved results. Weights, ranks and compared rank are assigned in [13] along with the threshold. The algorithm can be implemented in a system that involves the processing of multiple entities which are required to test and compare the results in multiple environments.

      Python Programming language has been used in [16] where online rules and offline rules are implemented to check the IP address, the number of clicks on the IP address and movement of cursor before clicking on the ad. This data is used to determine the normal person behavior and fraudulent behavior. Probability-based model approach is implemented in [25] which is better than learning based probabilistic estimator model. It has distorted towards particular time indexed label that hampers the accuracy, it is possible to even predict a behavior on the seconds scale of time or even a smaller timescale which gives better results.

      1. Access to user click information is limited.

      2. Lower accuracy using more attributes.


      The algorithm in [5] helps to determine the frequently occurring patterns without using top-k optimization with real time clicks. The method extracts information about click process events, it also describes the frequency of click of the sample events. Using the weightage of click stream it is able to calculate evaluation score, the data is used to generate click stream density function. However, the selection of k value in this method is very important and is optimized in subsequent research. [11] refers to the Internet advertising service platform using defense system that have been established using the third party to detect the click fraud which uses random forest classification algorithm producing highly accurate results of positive class 93% and negative class 91%.

      The proposed fraud detection in [14] uses CS-BPNN classification and SMOTE. BPNN is implemented in the variable click-fraud detection algorithm environment which avoids the local optimization of neural network and feature redundancy using Artificial Bee Colony. Data mining, honeypot, traffic analysis is used in [23] to verify whether the advertisement is normal, so that if any ad is being detected then honeypot sticks to it and exposes the bot leading to blocking of its IP. In [29] Content match advertising, social engineering attacks, Phishing and Blacklist evasion bidding style in which Bing search process is used which consists of policies. If any of the policy have not been satisfied by the ad then that ad will be detected as fraudulent.

      Light-GBM (Light Gradient Boosting Machine) algorithm is implemented in [2]. When there is a data which contains multiple attributes,feature parallelism can be implemented concurrently. When a large amount of data needs to be processed concurrently the data parallelism is brought into use. Voting parallelism focuses on data in which attribute has multiple features and votes for decision making. The prime advantage is the high performance along with the reliability and availability over traditional logistic regression models. Feature engineering of the data along with appropriate selection allows to improve the detection performance. In [4] the methodologies used are Logistic Regression, Support Vector, Machine Random Forest and Multinomial Naïve bayes, where 100000 random inputs were given and the discriminator classified

      63000 as valid clicks and remaining as invalid clicks and it also provided good accuracy in determining the valid and invalid click.

      SDK library (real ad network) click generation attacks are detected

      in [15]. Potentil risk of automated occurrence of an online fraud attacks in mobile advertising is evaluated and it also showed that 75% of the network was highly vulnerable to click fraud attacks. Pixel Clustering and methods like cost-per-click, cost-per-impression and cost-per-action are implemented in [15] where ads were filtered on the basis of user clicks and fraudulent users (whether Botnets or click frame) for great amount of data in minimal amount of time.

        Data Preprocessing: Collected dataset from Kaggle needs to be preprocessed in order to eliminate the null and unwanted values by using WEKA/python tool. WEKA has application such as Preprocess, Classify, Cluster, Select Attribute and Visualize.

        The system needs to implement the rules which are called as Offline Rules. Offline rules will appear such as Blacklist- Rule and Time-Period Rule, where Blacklist-Rule will maintain the Blacklist IPs which occur frequently. When the user visits the website its IP address will be matched with the Blacklist IPs to check if it a fraudulent IP. Time-Period Rule will detect the fraud based on the time that the normal person and fraud agent/botnet will utilize to click on the ad.

        The model uses Logistic regression method. This method basically implements the Sigmoid Activation Function where the decisions can be made as following:

        Fig1.: Working of Sigmoid Function

        The result 1 denotes that the resulting click is genuine. The result 0 denotes that the resulting click is malicious.

        Fig.2: Proposed Model System

        A request for data from server/google server/system is made from the database side. Only required data (Valid IP address and time of click) will be requested into database so that the memory consumption is efficient. The data will be further send for offline analysis which will check for rules such Blacklist rule and time period rule. Further the results will be validated and send to database. From database transaction of data will be analyzed by server for detection of click fraud activities.


The paper provides a brief overview and comparison between the different techniques used in advertisement click fraud detection. The traditional techniques used earlier for click detection and click validation are used for the purpose. Every technique mentioned has its own merits and demerits. A few common approaches like Logistic Regression, Traffic Analysis and JavaScript, Support Vector Machine are summarized and represented in the form of tables. The implementation of the traditional methods is cumbersome. The traditional methods are less accurate.

It has been observed that techniques under the JavaScript enabled system have an average accuracy of 90%. In system approach the advertisers can independently detect click fraud activities performed by clickbots and human clickers.

From the above tables most of the time logistic regression and offline rules based on user interface system gives a good accuracy in detecting advertisement click fraud. The Regression model gives higher accuracy for higher number of attributes and the offline rule(Blacklist Rule) helps in

minimizing overhead processes of similar data. The user interface system deals with the fetching of advertisement and usually also monitors the activity of a user with respect to the input functions mentioned. It also tracks the time spent by the users before clicking an advertisement to which is the most important validation property to verify if the click can be a genuine or a fraudulent.
