Large organizations often face difficult trade-offs in balancing the need to share information with the need to safeguard the privacy and security of sensitive data. A prominent technique for dealing with this trade-off is on-the-fly screen masking of sensitive data in applications. In this paper, the authors present a unique hybrid approach to screen-masking by combining the advantages of the context available at the presentation layer with the flexibility and low overhead of masking at the network layer. Their solution enables the identification of sensitive information in the visual context of the application screen, then automatically generates the masking rules to be enforced at runtime on the network traffic.
