Practical considerations using eSeals

While in the past waxed-seals where used to ensure the integrity, electronic devices are now able to take over this functionality and provide better, finer grained, more automated and more secure supervision. This demo shows a prototype eSeal system, with a computational device at its core that can be attached to a good and can be configured automatically using active tags. The eSeal monitors and seals different states sensed from the object's physical conditions. The eSeal is designed and implemented with flexibility in mind, allowing configurable integrity control settings. The system works with minimal infrastructure requirements and is functionally self-contained, such that goods can be supervised that are only accessible in certain locations. A major output of the eSeal prototype system demo is the support for intuitive user interaction, with regards to configuration and handling of the devices in the activity chain.
