1. A method for identifying Personally Identifiable Information (PII) through secret patterns, the method comprising:
receiving, by a PII tracking device, user data from at least one data source through a plurality of communication channels, wherein the user data comprises PII and non-PII, wherein the user data is associated with a user, and wherein the PII comprises a plurality of personal identifiers;
identifying, by the PII tracking device, the PII in the user data through a predictive model, wherein the predictive model is based on a classifier algorithm;
generating, by the PII tracking device, a secret pattern based on the PII identified through the predictive model, wherein the secret pattern is an identifiable label;
adding, by the PII tracking device, the secret pattern to each of the plurality of personal identifiers in the PII; and
identifying, by the PII tracking device, each of the plurality of personal identifiers through the secret pattern in real-time, when the user data is transmitted from the at least one data source to at least one data destination, wherein the plurality of personal identifiers is stored in the at least one data destination.
