1. A computer-implemented method comprising: opening a word processing document that includes document content and a plurality of comments inserted at a plurality of insertion points within the document content, wherein the opening occurs during a word processing application currently assigned to a user identifier, and wherein one or more of the plurality of comments includes one or more recipient identifiers; selecting a first set of comments from the plurality of comments where the user identifier is included in the recipient identifiers of the corresponding comments; identifying a first set of one or more encrypted comments included in the first set of comments; retrieving a user encryption key corresponding to the user identifier; decrypting the first set of encrypted comments using the retrieved user encryption key; selecting a second set of comments from the plurality of comments where the user identifier is not included in the recipient identifiers of the corresponding comments; displaying the first set of comments, each of the first set of comments being displayed at their respective insertion points within the document content; and inhibiting display of the second set of comments.
