User-generated content, e.g., documents, media, etc. is often created and shared over online document creation and file-hosting services. One technique to restrict access to shared documents is to specify a list of individuals with whom a document is to be shared. Current services do not address the scenario, frequent within enterprise settings, in which a document is made accessible to different groups of individuals based on their rank and clearance levels. Techniques of this disclosure encrypt shared documents such that access is granted to individuals in possession of a certain key. Certain documents, e.g., sensitive documents intended for view only by top management, are associated one set of keys, while documents viewable by more employees have a different set of keys. Document access retains the singlestep simplicity of create-and-share techniques. Access is selectively provided to users based on the key provided.
