1. A document review and security system comprising: a processor; and storage coupled to the processor, wherein the storage stores a computer program, and wherein the computer program, when executed by the processor, is configured to: divide a page image of a document into a plurality of sub-images forming geometric parts, wherein each of the sub-images includes a contiguous area of the document that is less than the entire area of the document, and wherein each of the sub-images is at least partially different from the other sub-images; present a first sub-image of a first portion of a document to a first reviewer by identifying a first element within the document that is contextually related to a second element within the document in accordance with predefined contextual relationship criteria and including the first element within the first portion without the second element; in response to receiving a request from the first reviewer to present a second sub-image, determine an extent of the second sub-image to be shown based on predefined criteria for a depth from the border of the second sub-image, wherein the second sub-image is adjacent to the first sub-image; and present the first sub-image and the second sub-image to the determined extent to the first reviewer; present a third sub-image of a second portion of the document to a second reviewer; and in response to receiving review action inputs from the first reviewer and the second reviewer, determine a disposition of the document from a plurality of dispositions, and wherein the plurality of dispositions include redaction of the document accordance with the review action inputs.
