Did you know that cell phone forensics are being used more and more these days? During criminal trials, it is now being used in court. A cell phone can help to establish the movement of the person who owns it.

Cell phones operate similar to two-way radios. When you make a call it is recorded by the carrier to show which towers your phone has contacted or pinged and what time it was.

This makes it very easy to trace a person's movement using their cell phone. Did you know that there are some mobile phones that now have a GPS chip in it?

This means that no matter where you are, if your cell phone is on you can be located at that exact moment in time. You can be traced to within several hundred yards of where you were.

In metro areas with multiple towers you can be traced almost to the block of where you were. Your cell phone is leaving a trail that you may not want.

Cell phone forensics is done by using the trail that your cell phone leaves. Although it is new, when done right, this type of forensics can be very effective.

Here are some of the things that this type of forensics can retrieve from anyone's cell phone.

- Deleted text messages no matter who they were sent to. In many cases text messaging is more popular than actually making a cell phone call and can provide all kinds of information.

- Address book entries that you have deleted. If you have something to hide it only makes sense you will want to get rid of these.

- Any pictures that you have taken and deleted. Cell phones make it easy to take pictures at almost anytime.

The retrieval of this information can tell a lot about a person's activities. Cell phone forensics is something that should not be done unless you know how and you make sure it is done legally.

This is why it is a good idea to learn more about it before you do anything else. It may be better to leave that up to a private investigator who can also take a cell phone ,blackberry or other handheld devices and download the information from it to analyze it.
