Abstract: A method for maintaining data privacy includes extracting a group of characters from one or more data fields associated with one or more documents. The method also includes associating a respective image of each character of the group of characters to a digital representation of the respective image based on extracting the group of characters. The method further includes randomly assigning, to each reviewer of a set of reviewers, a group of digital representations based on associating the respective image of each character to the digital representation. Each digital representation of the group of digital representations fails to satisfy a confidence condition. The method still further includes receiving, from each reviewer, a message indicating, for each digital representation of the group of digital representations, whether the respective digital representation is correct or a correction to the respective digital representation.

Abstract: A method of analyzing data is presented. The method includes receiving a query based for non-textual data, expanding search terms of the query, executing the query on one or more data sources, monitoring a specific data source selected from the one or more data sources.
