2. SIGNIFICANCE OF ONLINE FRAUD WITH WEB SECURITY
1.INTRODUCTION
TherecentCOVID 19pandemichasfundamentallyadjustedhowpeopleandorganizationsapproachtheirday to dayexercises.For e commerce business players, the online movement has surged as consumer volumes keep on fluctuating impressively. The expandingnumberofonlineusershasnotjustimpactedhowe commercebusinessmerchantsapproachtheirbusinesspracticesbut has also influenced a pattern of fraud occurrences. Based on recent studies, users now account for nearly 30% of all online
The “useofthe internet”[1]hasbecomemoreprevalentgloballysince the Covid 19 Pandemic and the surge of the utilizationof digital technologies, we are currently witnessing a rise in online fraud, security breaches [1]. The wide variety of information that is available on the web has greatly impacted our lives. Due to the increasing number of hackers, the security measures related to online transactions have also become more stringent and to the surge of users who share their private information while shopping online, the security dangers of this have become more prevalent. Worldwide card fraud misfortunes added up to 28.65 billion US dollars in 2020 and are predicted to increase to more than 34 billion by 2022[3]. Numerous precautionary measures have been taken to keep up with the development of these dangers. There are various ways to safeguard the sensitive data of the users. These include implementing a strong “fraud detection system” [4] (FDS) at the source Bank which issues Cards to the users and Behavior Analysis techniques and keeping the data secure [4]. Usually, we are using Captcha, OTP and I am not a robot method, but we can’t guarantee that these are 100% secured, moreover if any fraudulent transaction patterns are detected by the system, it will block the user procedure, but only after three invalid attempts. To plan a strong and effective Fraud Detection System to consider the peculiarities of the fraud phenomenon, and various methodologies have been implemented for Fraud Detection [2]. To prevent such incidents, the system must be regularly updated, and re verification is performed on all transactions. The increasing number of breaches and hacking attempts on user data could also lead to a spike in the number of transactions. This paper shows the methodologies utilized in Fraud detection in E commerce.
