Like too many ppm of solvent vapor near a flaring pilot light, metadata is brimming with potential trouble as well.

Data about data. Metadata describes how and when and by whom a particular set of data was collected, and how the data is formatted. Metadata is essential for understanding information stored in data warehouses and has become increasingly important in XML-based Web applications.


The image here contains:

Orientation of image:  1
File change date and time:  2013:02:18 19:43:06
Software used:  Adobe Photoshop CS2 Macintosh

What sort of identifying info is passed along invisibly in files like images, videos, or music? A digital camera could potentially copy its serial number to every picture file and video. The serial number in turn is possibly traceable to a purchaser through billing information.

Maybe some whistleblower hackers out there scrutinize all the header information written to files for every product manufactured. Or not.

I remember hearing in the 90s that some compilers insert metadata into binaries that can be used to identify the computer they were built on to help convict virus authors. Probably some combination of hardware serial #s, physical MAC addr etc.

If you're gonna do something illegal with a computer just mug someone for their smart phone and destroy it when you're done haha.
