Systems and methods for online fraud detection
Systems and methods for preventing fraud are disclosed. The system includes, for example, a front end device that is operatively coupled to a back end device. The front end device is configured to generate a first dynamic device identification based on dynamic device characteristics of the front end device. The back end device is configured to generate a second dynamic device identification based on the dynamic device characteristics of the front end device to authenticate the front end device. The front end device can also authenticate itself through an Internet of Things (IoT) device that has a trusted connection to the back end device.
1. A method, comprising: storing, in a front end device, device characteristics of the front end device with corresponding time stamps;
sending the stored device characteristics with the corresponding time stamps to a back end device;
downloading a device identification generator from a plurality of device identification generators stored at a back end device;
generating a first dynamic device identification for the front end device based on one or more device characteristics;
sending the first dynamic device identification and a time stamp corresponding to the one or more device characteristics used to generate the first dynamic device identification to the back end device;
generating, by the back end device, a second dynamic device identification for the front end device based on the device identification generator and the time stamp used by the front end device;
comparing the first dynamic device identification and the second dynamic device identification to authenticate the front end device to the back end device;
downloading an application from the back end device, wherein the generating of the first dynamic device identification is performed by the downloaded application; and wherein the generating of the first dynamic device identification is performed by a same application as downloaded by the front end device.
2. The method according to claim 1 , comprising changing the dynamic device characteristics with time.
3. The method according to claim 1 , comprising:
downloading, by the front end device, a device identification generator from the back end device; and
selecting, by the back end device, the device identification generator for downloading from a repository of a plurality of different device identification generators.
4. The method according to claim 3 , wherein at least some of the device identification generators have different combinations of device characteristics and mathematical operations.
5. The method according to claim 3 , wherein at least some of the device identification generators have different combinations of seed numbers and device characteristics.
