Was anyone surprised to learn that Canadian spying organizations are, well, spying on Canadians?
The Communications Security Establishment, Canada’s electronic spy agency, has stopped sharing certain metadata with international partners after discovering it had not been sufficiently protecting that information before passing it on.

Metadata is data that describes other data. Meta is a prefix that in most information technology usages means “an underlying definition or description.” Metadata summarizes basic information about data, which can make finding and working with particular instances of data easier.
Jump to Definition – Metadata is “data that provides information about other data”. Two types of metadata exist: structural metadata and descriptive metadata. Structural metadata is data about the containers of data. Descriptive metadata uses individual instances of application data or the data content.
Recently Dr. Nik Richers presented a series of posts on metadata. Links are below.
