New solution helps law enforcement isolate mobile devices while still being able to access them

Faraday bags help secure seized mobile devices
The Phone Shield Faraday bag allows a device to be isolated from an incoming or outgoing signal, while still giving access to data on the device.

Law enforcement and counter terrorism agencies now have a solution to the problems of what to do with mobile phones and other connected devices that are seized from criminal suspects.

At present, devices and data held on them that are seized can provide valuable intelligence and evidence if they are left switched on, but officers run a number of risks in not turning off the devices. A device that is left switched on can potentially be remotely wiped, or any communications that are received after the device has been seized may not be lawfully accessed, and in certain cases, active mobile phones could even be used to remotely trigger explosive devices.

Now UK company Disklabs is offering a solution to the conflict between the need to isolate the device while still having access to the data on it, with the launch of its Phone Shield Faraday bag line up.

The range consists of small, lightweight bags constructed of silver, nickel and copper, which create a Faraday shield, an enclosure of conductive material which blocks external non-static electric fields such as mobile phone signals.

A transparent window in the bag allows officers to continue to access the device, so that they are still able to actively carry out investigations on site, without having to remove the device to a fixed Faraday cage.

The bags are available in mobile phone, laptop and holdall sizes, and the company also manufactures cable shields, which allow the device to plugged in to a charger to keep it powered, without the risk of the cable acting as an antennae. The solutions are capable of blocking all major frequencies, including: 900Mhz, 1800Mhz, 1900Mhz, 2.1Ghz, Bluetooth and Wi-Fi.

Harlan Simpson, director of Disklabs commented: "We are getting more and more orders from organisations that simply were not aware that these signal blocking products were available. We are now receiving orders from several Counter Terrorism Units around the world."

The company, which specializes in computer forensics and data recovery, is also looking for distributors for its Faraday bag range.
