Systems and methods using a cloud proxy for mobile device management and policy

Systems and methods for device identification for management and policy in the cloud, using a combination of several hardware parameters and user's identification to generate a unique identifier for a user device and associated user. IOCTL and Assembly can be used to get the different hardware parameters. All the hardware parameters can then run through a process to generate a fixed size hardware fingerprint. A base64 encoding can be performed to convert it into a string, for consumption of database. The resultant identifier is unique and it is never stored on machine. The application can simply generate it whenever needed. The resultant identifier can used by a service provider to uniquely identify the device even when the device is moving hands or locations. The resultant identifier is never stored, so moving data from one device to another will not result in the same identifier for two devices.
