UK firm Iceberg Systems is beta testing a new technology, Safe Haven, that identifies the use of portable devices with imaging capabilities, and disables this feature within a specified area. Interest in this technology is driven by estimates that there will be 900 million such imaging devices in use worldwide within the next four years. The proliferation of wireless technology facilitates the transmission of images without permission of individuals and corporations, and has resulted in instances where they have been banned to protect privacy and prevent corporate espionage.
