Businesses are increasingly reliant on mobile apps to deliver services, yet face challenges from user-initiated app cloning, which can facilitate fraudulent activities such as promotional abuse, usage limit bypassing, ban evasion, vote manipulation, and account takeover. App cloning, particularly prevalent on Android due to its open nature, allows users to create multiple instances of an app on a single device, leading to potential revenue and trust erosion. While app cloning can have legitimate uses, the risks necessitate robust detection and prevention strategies. To combat these threats, methods such as analyzing usage patterns, implementing anti-fraud algorithms, and utilizing composite identifiers are suggested. The Fingerprint Device Intelligence Platform offers a solution by leveraging over 70 signals to provide a stable identifier and detect cloned app usage, enabling businesses to implement measures like additional authentication and risk scoring to mitigate fraud. Through these efforts, businesses can protect against the adverse effects of app cloning while maintaining a seamless user experience.
