Abstract: A method and system for secure download includes generating a path to a location where a downloadable object is temporarily stored. The method can include receiving a request for a downloadable object, generating one or more unique identifiers, creating a path to the requested object using the unique identifiers, storing a copy of the requested object in a temporary location indicated by the path, and returning the generated path to the requestor. The method can further include receiving a path to a downloadable object and, responsive to a determination that the path is valid, returning the downloadable object. A generated path can be rendered obsolete and its corresponding file removed from the temporary location after a predefined time interval has elapsed. A database of the generated paths and associated files may be periodically checked, and those paths and files that have been stored in the database beyond a pre-definable expiry time can be removed.
