1. A method for obfuscating data, the method comprising the steps of:
receiving a request from a client to obfuscate data records associated with the client, the data records being stored in one or more databases throughout a network;
searching, by a crawler tool, for one or more occurrences of the data records appearing throughout the network based at least in part on one or more tasks to obfuscate data corresponding to the request, the one or more tasks being derived from the request and stored at a ledger;
storing, by the crawler tool, information corresponding to one or more found occurrences of the data records;
determining that the one or more found occurrences of the data records can be obfuscated without causing undesirable consequences elsewhere in the network if at least a portion of the found occurrences are relied upon by other applications in the network;
selecting the one or more tasks from the ledger based on a determined priority; and
obfuscating the one or more found occurrences of the data records based on the one or more selected tasks.
