Abstract: This application relates to a client-server architecture that enables file sharing between an instructor and a class. The files are stored in a storage service accessible via a network, and a separate copy of each file can be shared with each student in the class. In order to facilitate the sharing of multiple copies of the file, a share pool is created in a partition of the storage service allocated to the instructor. The share pool includes a number of stub files that are placeholders for clones of the shared file. A share handler service receives a request to share a file with a class, requests a number of stub files from the share pool, and utilizes the number of stub files to generate clones of the shared file in the partition of the storage service. Students are then granted access to the clones in the partition.

Abstract: Some embodiments provide a method for storing multiple data assets in a folder structure on a cloud services platform. The method stores a separate encrypted structure for each of the data assets on the cloud services platform. A same first key provides access to each of the encrypted structures. The method stores, on the cloud services platform, a folder structure with an encrypted copy of the first key. The method stores a parent structure of the folder on the cloud services platform. The parent structure includes an encrypted copy of a second key that provides access to the encrypted copy of the first key.
