Standardization is the key to interoperability. We have experienced the value of interoperability in service
computing and many other occasions throughout the history of computing. Standardization efforts need to
be carried out as early as possible to avoid significant frustrations and costs that may occur at later stages.
Technology needs ensure the accuracy of the data up to an acceptable level as it is one of the main motivations
behind the Sensing as a service model. It is important to anonymize the sensor data collected. Sensitive
information such as location need to be implicitly altered to protect the sensor owner privacy. This should
be done in both the hardware and software levels. For the hardware level, we need to develop next generation
security appliance that can be used to anonymize data at the ground level (i.e. physically close to the sensor
owners). Techniques similar to privacy preserving data sharing ad matching [40] need to be developed in order
to combine sensor data to anonymize entities / profiles (excluding sensitive data) later at the server level.
