In the given research the anomaly is considered as a fraud. The paper is devoted to the development of the method, aimed at detection of the data anomalies mobile applications installation. Anomaly (fraud) detection method on the basis of anomalies in data, which, unlike the existing ones, allows to solve the heterogeneous data resolution problem on which fraudulent decisions are made, reduce the size of the data and conduct a classification of users, is proposed. An experiment was conducted on the basis of a representative sample of 284,807 users acting from a real mobile application. The efficiency of the proposed method, the accuracy of which is 99.14%, is shown.
