Abstract: A method and system for mitigating risk of frauds related to streaming content consumption is disclosed. Users' interaction data corresponding to a plurality of users of a digital platform related to streaming content is received. A set of users from the plurality of users is determined based on the users' interaction data. The set of users is determined based on the presence of at least one of an outlier event and an anomaly in their respective user interaction data. For each user of the set of users, a user breach profile for a user is generated; a fraud event is determined by applying at least one rule on the user breach profile; at least one action is triggered in response to a determination of the fraud event; and a risk score is determined for the user based on the user breach profile to monitor user interaction data of the user.

Abstract: A system and a method for authenticating a device of a user is provided. A set of parameters of the device or the user are captured from the device. The set of parameters are categorized into first and second categories including first and second parameters, respectively. One of the first and second categories is selected based on a trust score of the device. The first challenge is generated based on the first parameters, when the first category is selected. The second challenge is generated based on the second parameters, when the second category is selected. The first or the second challenge is transmitted to the device, and a response message is received in response to the first or second challenge. The response message is validated to authenticate the device of the user.

Abstract: A method for offline playback of multimedia files includes receiving an encrypted multimedia file and an encrypted file key from a server. The encrypted multimedia file is transmitted to a communication device in a vehicle based on a selection input by a control device. A request is received for a file key from the communication device. The encrypted file key is decrypted by using a device key to generate the file key. The file key is transmitted to the communication device for the offline playback of the multimedia file.
