What is Forensic Data Recovery?

Forensic data recovery is not magic; in fact it is actually very technical. People always wonder how the forensic experts can conjure up stuff from smartphones, tablets or hard drives that the owners thought were gone. So, how does forensics data recovery work?

Sometimes forensic data recovery is as simple as trying to reconstruct the information on a damaged hard drive, disc or memory card. At other times, it may include the resurrection of data that was thought to be lost or deleted, the bypassing of security systems or the study of a smartphone for traces of certain activity.

Because specialists in forensic data recovery may be working with computers which have been seeded with safety measures to prevent legal investigations, they must use special procedures to avoid compromising or erasing data.

Forensic data recovery is not magic at all. It is highly sophisticated and in order to be admissible in court, must be completed by professionals using complex tools and protocols.

Your video may prove guilt to you, but not in court

Because of the constant flood of easily accessible technology, security cameras seem to be more plentiful than ever before…

- Many private residences now install security cameras around the exterior of their property.

- Business owners install cameras in work areas and entrances.

- Parents with children often install surveillance equipment to keep tabs on the safety of their children with caregivers.

Those constantly rolling cameras can often hold people accountable for bad behaviour. In the event of videotaping a suspected criminal, people have a false security about their video skills. You might assume that you don’t need the services of professionals like DLA digital and cellular forensic investigators, after all, you can do it yourself, right? You will change your mind after you read what goes into providing video evidence for court…

- When you review a video to make sure you have clearly caught a crime on tape, don’t just immediately decide that dark footage is useless. Actually, dark footage is easier to enhance than overexposed footage.

- Immediately confiscate the equipment used for the video. If the event was recorded through the use of a camera phone, home camcorder or a security camera, immediately turn this equipment and video over to the proper authorities.

- Quickly make a decision about how you wish to allow the footage to be rewound and repeated. In a court trial, jurors may not be as shocked by a crime caught on video if they repeatedly view it.

- If at all possible, involve a video expert experience in evidence handling to be involved with the set-up and operation of the equipment. This person is not only easily accessible for computer glitches. But also, the presence of a legal video expert gives you credibility.

In order for video evidence to be admissible in court, it must comply with the proper recording and preservation guidelines. You might know you have evidence, but you might not be able to use it like you think.

If these important tips have made you question whether you are capable of producing the required evidence of wrongdoing or to prove innocence, it’s time to call the professionals at DLA!

Mobile Phone Analysis

Mobile devices are becoming increasingly powerful and popular, with people even sometimes carrying more than one. However, their increasing capability provides more opportunity to store and circulate information.

Mobile devices have many different features, like the ability to take photos and videos. When a multimedia file is taken, many devices automatically embed GPS location of the handset at that time. This then allows the location of the user at that exact moment to be established at a later date.

Multiple communication features, such as Bluetooth, WiFi 3G and 4G enable the transfer of information that can even cross international boundaries. Users can browse the internet, send and receive emails, post blogs and even removable media cards can be inserted into the device allowing information to be exchanged.

Depending on the client, the following information can be recovered from a mobile phone:

- Email
- Call history
- Photos
- Videos
- WhatsApp history
- Passwords

Mobile devices are similar to computers, but with far more powerful capabilities. The value of the evidence found on a smartphone or any other mobile device must never be overlooked! DLA has the cellular and digital expertise to extract and uncover the evidence you need.

The other side of mobile forensics

Mobile or cellular forensics isn’t just about finding WhatsApp messages, images and recent calls; it can also reveal much more. There’s a whole other side to it, which can include carrier data, call logs, undelivered messages and important data that reveals your exact location at the time of the incident. Matched together with the information saved to your mobile device, and mapped together with street names and landmarks, carrier data can enhance data on your device.

The best thing is, if cellular forensics is being used in an important crime case, they can be used to break the case. However, a lot of investigators overlook this critical evidence.

Most cell towers consist of poles that send and receive signals in three sectors; this makes it easier as it enables them to identify which side of the tower communicated with a cellular device.

Carriers keep detailed call records of these communications for billing purposes, so the data includes information like date, call length, whether a call was inbound, outbound, or went to voicemail.

Tower data reveals whether the device was in motion or stationary. A person dialing from one location will hit the same side of the same tower, but a person on the go will hit different towers and different sides.

In an investigation that uses mobile forensics, carrier data information can be vital. It can be used to place a phone in a certain area at a specific time, identify call patterns, establish timelines and identify suspects.
