Abstract
Systems and methods for generating and handling tokenized links pointing to web-accessible files are provided herein. The tokenized link obscures the filepath of the file and is associated with a permission scope that consists of a set of criteria for evaluating conditions for access to the file. The link may be freely shared and still provide access restrictions within a domain to the linked file without needing to modify the permissions for the file itself. A user with access to the file may thus freely share the link with other users, who may in turn share the link with yet other users, and be assured that only authorized users will gain access to the file. The tokenized links thereby improve the security of the files, the user experience of the distributing and receiving users, and the functionality of the devices using the tokenized links.
