1. A system for replacing sensitive data in documents, the system comprising:
a non-transitory storage medium storing instructions thereon; and
at least one processor operatively connected to the non-transitory storage medium, the at least one processor, upon executing the instructions, being configured for:
receiving an image of at least one document;
clustering said image of each of said at least one document into different cluster fields, each cluster field containing respective cluster data content and having a respective cluster position;
recognizing specific types of data in said different cluster fields to thereby determine if said data in said different cluster fields comprises sensitive data based on cluster data content and the cluster position to assign a respective sensitivity to said data, said sensitivity being indicative of a sensitivity level of said data; and
replacing sensitive data of at least one specific type of data in said different fields with replacement data based on the respective sensitivity being above a threshold.
