Remote file storage with multiple access levels

Abstract

Disclosed embodiments provide techniques for accessing a document from a cloud storage system and controlling the display of sensitive data within the document based on user permissions. One or more restricted information segments are identified within a document to be stored on the cloud storage system. Restricted information segments can include anything within an electronic file for which it is desired to provide multiple levels of access. In some embodiments, the restricted information segments are automatically identified via computer-implemented natural language processing (NLP) techniques. For each restricted information segment, one or more alternative data sequences are generated. The alternative data sequences are encrypted using various keys residing on a client device associated with a user. The keys can be used to decrypt data stored within a multiple-value encrypted field structure. In this way, multiple levels of information can be disseminated to an audience with various permission/privilege levels.
