The question on everybody’s lips these days is “How can cell phone forensics help in a criminal case?” Many people are very interested in this technological breakthrough. It allows us to find out deleted text messages, call details and other data from the deleted cell phone. This can be very useful in trying to discover any evidence of a crime that you may be accused of. Many private investigators are now using cell phone forensics to their advantage to help in the resolution of crimes.
How can cell phone forensics help in a criminal case? You can bet your bottom dollar that when a private investigator unearths some evidence to justify a suspect being charged with a crime, he will make sure to talk to the law enforcement authorities about it. This is his way of making sure that you do not get yourself into something you are not supposed to be in. This is why you should have a strong reason for deleting a particular message or phone number. Just imagine the uproar if law enforcement officials found evidence that you were deleting those texts before they arrested you!
A cell phone forensic examination is performed by professional investigators who know exactly what to do in such a situation. They will access the deleted data of the cellular phone through the telephone carrier and retrieve all deleted text messages, contacts and call logs. They can also recover deleted pictures and videos. There are several different types of cell phone forensic tools available. Here is a quick overview of the major types of tools and what they can be used for:
Recover deleted data, even after a smartphone has been wiped. How can cell phone forensics help in a criminal case? If investigators can recover data from a cellular phone that has been erased then they can use that information to determine which way the BlackBerry was taken and whether or not it was simply formatted (turned off). If the phone was simply “paired” with another device that can work as evidence, the forensic tools can determine which device is responsible and which text message was sent to which person.
Retrieve deleted cell phone text messages. It is nearly impossible to know whether a smartphone was “lost” or deleted by the user. The only thing that can be sure is that the phone was “purged of all data”. This is one of the more common reasons why people ask “How can cell phone forensics help in a case like this?”
Recovering deleted data from a memory card. Again, it is almost impossible to know whether or not the user has deleted a specific message. However, if the user has accidentally deleted a file, it can still be recovered using a recovery tool. This is just one of the examples where a skilled investigator can recover deleted data on a BlackBerry.
Recovering data from a PDA. PDAs are unique in that they have a removable memory, much like a USB drive. These devices can be formatted and data can be retrieved with a software program that is compatible with most PDAs. Just like USB drives, these devices can be formatted and data extracted using a data recovery program that is compatible with most PDAs. Again, how can cell phone forensics help in this situation? The investigator will pull together a list of all the possible contacts for the target phone and then perform a reverse search to see if any of them were erased.
Recovering deleted data from a smartphone. As you may have guessed, there are many situations in which an investigator will require the skill and training to recover deleted data from a smartphone. A smartphone has tons of personal and business data stored on it. It also has a storage system that can easily be damaged or corrupted. There are some cases in which the user has unintentionally deleted all of the necessary data or has made it impossible for anyone to access any of it at all.
