Abstract
Opaque I/O objects are described which can be used in a variety of mobile code systems to permit unprivileged applets to perform a wide variety of I/O operations in a safe manner. Such opaque objects permit limited I/O without requiring the user of an applet to confer trust or privilege on the applet, and without exposing the user to a risk of his data being destroyed, compromised, or stolen by malicious applets.
