The online food delivery industry has experienced significant growth due to the convenience of ordering meals online, a trend expected to continue with a projected global market volume of $1.85 trillion by 2029. However, this growth has attracted various forms of fraud, including driver account sharing, promo abuse, ghost orders, and account takeover fraud, which pose safety and financial risks to consumers, delivery platforms, and restaurants. Driver account sharing involves selling driver account information, which can lead to unvetted individuals making deliveries and associated safety risks, while promo abuse fraud exploits promotional offers, resulting in financial losses for businesses. Ghost order fraud involves creating fake deliveries to inflate earnings, and account takeover fraud sees fraudsters accessing user accounts to make unauthorized purchases. To combat these issues, strategies like multi-factor authentication and device intelligence can help enhance account security by detecting suspicious activity, though they must balance security with a seamless user experience to avoid deterring legitimate customers.
