One rather scary point from the study is worth contemplating:

Of that portion of the digital universe created by individuals, less than half can be accounted for by user activities - pictures taken, phone calls made, emails sent - while the rest constitutes a digital "shadow" - surveillance photos, Web search histories, financial transaction journals, mailing lists, and so on.

In other words, the trail we leave involuntarily in the digital universe - information about us - is now larger than the information we deliberately create.
