2nd Year uni student - Mobile forensic app

Post Posted: Wed Jan 23, 2013 7:21 am

Hi,

I'm currently in my second year at the University of Derby studying computer forensic investigation & network security. For one of our modules we have been placed into a 'company' to develop new software. We have decided to create an app (for use with phones or tablets - android only for now as we only have 12 weeks), that allows a user to create a case, and document everything found at a scene.

The app would go something like:
Open the app >> Login (this is just incase someone gets hold of your device as you don't want anyone playing around with the app) >> You'll be greeted with a list of devices that you may find >> Click one (IE Hard Drive) >> You will then be able to take a picture, note down the serial and any other codes >> You will do this for everything you find, once finished the app will be able to generate a report based on what you have entered which can be used when creating the final court/internal report.

Just wondering what sort of features you guys would want, what issues we may run into, any possible legal problems (we want the evidence to be admissible)? Or anything else you could think of?

Thanks

As far as issues go, try to think of who would be using the app and what benefit over existing methods it would provide.

If your target is a police force for instance, many of them do not have the resources to allow forensic analysts to gather data at the scene, only police officers. This would change the layout and language of your application as it would have to be tailored to suit a less technologically knowledgeable person/people.

Also the person using your application would need an untouched, dedicated business phone that the application could be used on. If not, (as if the case with many police forces) then the practically of such an application is seriously questioned.

If they do have such a device, how will your application save the police force time/money over using conventional methods (i.e. Camera, seizure forms and police notes). If you can't prove it would save time then practically it would never get used. This is before you even consider the legal issues.

They are many other issues dependant on what your user audience is. I would recommend trying to get in touch with those who you intend to be your user and gather some client requirements, researching how they do things currently.

I hope this is of help.

If this application is for only for documenting electronic devices that have been seized it will be much more hassle during an execution of a warrant compared to the practices that are already implemented by a lot of Police forces. Although if it was an application that took over the form filling for all items that could be seized during a warrant, it could be very beneficial.

How about an android app that's along the lines of QCC's CaseNotes?

You could include the ability to take photographs directly into the report (and hash them) then export the report as pdf (with final hash).

This would be useful for both examiners and/or police officers (as is QCC's CaseNotes).

Thanks for the replies, has opened up quite a few things for us.

So lets say a private company was asked to seize 'Johns' computer; a person is using a dedicated android device to open the app (Say a £100 tablet - we're trying to keep the app lightweight as possible), they create a 'new case', they take pictures of the computer (Note down the make/model etc), picture the internal components with serials etc - you know the drill. Once all pictures and data has been added, the PDF report can be printed, emailed, or saved online (Online may be an option in the future, depends on security risks).

The report created by the app is court friendly; so all that needs to be done once you get back to the office afterwards is the investigation into what's on the hard drive / RAM / any other devices.

More loosely if you check some of the existing tablet based "inventory" software, the procedure is more or less the same, (but instead of the picture/pictures taking a bar code scan is performed).

We could include an option to scan a barcode instead of taking a picture - Would make it easier for items with bar codes, and then if there isn't a code then a picture could be used.



Alex: Thanks for the link to QCC's CaseNotes - Has quite a bit of information to help with security related stuff; Just need to read into how much can be done with android.
