== History ==
 
  
Palm Computing was founded by Jeff Hawkins, Donna Dubinsky and Ed Colligan.  The original purpose of the company was to create handwriting recognition software for other devices (Graffiti).  The initial idea for the devices came from Hawkins' habit of carrying a block of wood in his pocket.

+
Wikipedia has a nice [http://en.wikipedia.org/wiki/Metadata entry on metadata].
The initial Palm device released in 1996 was called the Pilot.  Because Pilot Pen Corporation brought forth a trademark infrigement case, the second generation device released in 1997 was named the PalmPilot. 
+
 
+
The Palm was not the original PDA device released, but benefited from the failure of Apple's Newton. 
+
 
+
The Palm OS initially featured personal information management (PIM) tools such as Calendar, Contacts, Memo Pad, Expense and Tasks. 
+
 
+
Presently, version 6.0 of the Palm OS is under development (Cobalt).  Cobalt features a Linux-based kernel.  There are presently no devices released using Palm OS 6.

The 3Com Audrey was created to be a kitchen computer in 2000-2001.  It was a mainly a used to access the Internet.  Cisco then bought out 3Com and the Audrey was no more.  One noticeable aspect of the Audrey is how people can hack it.  They have turned it into anything from a web server to a chatting client.  It runs QNX with PalmOS extensions.  This allows it to be hacked extremely easily.

The first product released in 1999 was called the Handspring Visor, a clone of the original PalmPilot with minor additions, that used the newly created Palm OS. One of it's most prominent features was USB support and an expansion slot for memory cards, both of which were not yet popular at the time.

Metadata is data about data. Metadata plays a number of important roles in computer forensics:

  • It can provide corroborating information about the document data itself.
  • It can reveal information that someone tried to hide, delete, or obscure.
  • It can be used to automatically correlate documents from different sources.

Since metadata is fundamentally data, it suffers all of the data quality and pedigre issues as any other form of data. Nevertheless, because metadata isn't generally visible unless you use a special tool, more skill is required to alter or otherwise manipulate it.

Kinds of Metadata

Here are some kinds of metadata that are interesting in computer forensics:

  • File system metadata (e.g. MAC times, access control lists, etc.)
  • Digital image metadata. Although information such as the image size and number of colors are techncially metadata, JPEG and file formats store additional data about the photo or the device that acquired it.
