Metadata defined: “The term is ambiguous, as it is used for two fundamentally different concepts (types). Structural metadata is about the design and specification of data structures and is more properly called “data about the containers of data”; descriptive metadata, on the other hand, is about individual instances of application data, the data content.” (Wikipedia)
So its not just the data (information) itself, but also the trail it leaves that enables it to be tracked. When that activity takes someone into the datacenter or beyond “secure” firewalls then there’s a need for concern.
“A lack of transparency from the “powers that be” is forcing businesses to quickly rebuild their strategies around privacy and trust to protect their intellectual property and ensure that employees act responsibly. But this is increasingly difficult considering the amount of information that businesses develop, store, and share, on a daily basis, from a multitude of devices. Cisco predicts that there will be 25 billion devices connected to the internet by 2015, and 50 billion by 2020, amounting an unthinkable volume of data traveling between different systems and devices. This data boom is leaving business struggling to make sense of information, let alone protect it.”
