Claim of US Patent No. 9,319,379

1. A method of generating a user identifier, the method comprising:
identifying, by a client stored in a memory of a device and executable by a processor of the device, that the client does
not have a device identifier associated with the device, wherein the device identifier is a device system identifier unique
to the device;

requesting, by the client, the device identifier from the device in response to identifying that the client does not have
the device identifier;

receiving, by the client, the device identifier;
masking, by the client, the device identifier with client logic; and
generating, by the client, the user identifier based on the masking, wherein the user identifier is unique to the device,
and wherein the user identifier is attached to one or more interactions with one or more applications used by the device.
