Abstract: A computer-implemented method of executing a policy-based operation on a shared computer infrastructure includes storing in a computer memory a dynamically extensible metadata system that is in communication with a processor that executes policy-based operations, where the dynamically extensible metadata system includes a data structure, a collection method, a policy processing method, and a policy condition. The collection method is then executed to collect data from a first computer resource in the shared computer infrastructure using a first data structure and from a second computer resource in the shared computer infrastructure using a second data structure, where the first data structure and the second data structure are different data structures. The collected data is then processed with the policy processing method to determine if the collected data meets the policy condition.

Abstract: Techniques for multimedia metadata security are disclosed. In one particular embodiment, the techniques may be realized as a method for multimedia metadata security comprising receiving an indication that multimedia metadata has been created for a multimedia file, and encrypting, using at least one computer processor, the multimedia metadata stored in a body of the multimedia file.
