Although not strictly for forensic purposes, '''visualization tools''' such as the ones discussed here can be very useful for visualizing large data sets. As forensic practitioners need to process more and more data, it is likely that some of the techniques implemented by these tools will need to be adopted.
+
== Guidelines ==
  
==Programming Languages and Developer Toolkits==
+
# If on, switch it off. If off, leave off.
If you are building forensic tools, you probably want to start with one of these:
+
; Java and Swing
+
: Advantage: Portable and lots of good documentation out there.
+
: Disadvantage: Programs are a bit verbose, and only offers about 1/2 the performance of C
+
  
; Python with tkinter
+
#* Note only under exceptional circumstances should the handset be left switched on and in any case every precaution to prevent the handset connecting with the Communication Service Provider should be made. Consider use of one of many [[wireless preservation]] or [[RF isolation]] techniques. Note that the slightest signal leakage will allow an overwriting text message through even if a phone call can't get through.
: Advantage: Portable
+
: Disadvantage: Python is one of the slowest modern languages around.
+
  
; Python with wxWidgets
+
#* Instead of switching off, it may be better to remove the battery. Phones run a different part of their program when they are turned off.  You may wish to avoid having this part of the program run.  
: Advantage: Portable and a better development environment than tkiner
+
: Disadvantage: wxWidgets is not installed by default, so you'll need to get it installed. Not as well documented as Tkinter
+
  
; [http://www.pyside.org Python with Qt (PySide)]
+
#* Note that removing the battery or powering off a mobile phone may introduce a handset unlock code upon powering the device on.
: Advantage: Portable and a better development environment than tkiner or wxWidgets
+
: Disadvantage: Though not difficult, PySide has to be installed separately
+
  
; [http://processing.org processing.org]
+
# Collect and preserve other surrounding and related devices. Be especially careful to collect the power charger. The phone's battery will only last a certain amount of time. When it dies, much of the data on the device may go too!
: Advantage: Programming language specifically developed for visualization; compiles to java byte code
+
: Disadvantage: Very oddball
+
# Plug the phone in, preferably in the evidence room, as soon as possible.
 +
# Retain [[search warrant]] (if necessary - [[LE]]).
 +
# Return device to forensic lab if able.
 +
# Use [[forensically sound]] tools for processing. However, also remember ACPO Principle 2 says: In exceptional circumstances, where a person finds it necessary to access original data held on a computer or on storage media, that person must be competent to do so and be able to give evidence explaining the relevance and the implications of their actions.
