SELECTIVE ENCRYPTION OF VISUAL DATA Classification of Application Scenarios and Compar­ ison of Techniques for Lossless Environments

We discuss techniques for selective encryption of visual data. After in­ troducing a classification of application scenarios for selective encryption we derive conditions for the sensible employment of such an approach in each scenario. Finally, we propose and evaluate experimentally sev­ eral selective encryption approaches for a specific lossless application scenario.
