This Mobile Phone Data Proficiency Test has been designed to test the proficiency of participants in:

  • extracting seeded data from files created from 2 different phones: one smartphone and one feature phone and examining the extracted data
  • identifying certain data types from the extracted data
  • identifying specific activity (if this is normally carried out by the participant).

Inter-Laboratory Comparisons
At the end of this Proficiency Test we will prepare a detailed Inter-Laboratory Comparison report (anonymising all participant details) and provide a copy to all participants. This will allow all participants to compare their performance with other laboratories, with the aim of identifying any requirement for improvement or examination of processes, training, etc.

Participants can then use the results of this test as evidence for compliance to Section 5.9 of ISO 17025 (“Assuring the quality of test and calibration results”) and for helping to ensure customer confidence in the reliability of their work and Section 24 of the Forensic Science Regulator’s “Codes of Practice and Conduct” (“Assuring the quality of test results (ISO 17025:2005 ref. 5.9”).

Furthermore, the results of these tests can be used on a wider basis to help identify positive and negative trends with the aim of assisting in the continuous improvement of these types of services.

Kits Available In This Round
The kit consists of a USB flash drive containing files extracted from 2 different mobile phones, plus other supporting files. Two different kits are available in this Round offering Standard and Enhanced options, reflecting different types of operations undertaken in digital forensics labs.

DFS001 (Standard):
Contains data extracted into bin files from a Samsung Galaxy J1 Ace SM-J110H Android phone and a simpler Nokia 105 RM-1134. Participants will need to load the bin files, as though they were mounting a phone, onto their software / hardware systems, undertake extractions (Logical and Physical, if possible), and produce readable data. Participants will be asked several questions to see what data they have been able to extract from both phones. This Kit is designed for digital forensics units that only undertake data extractions, but do not undertake any analysis or interpretation of the data.

DFS002 (Enhanced):
This kit is identical to DFS001 (above). However, in addition, participants will also be asked several questions about what the data says about the activities of the phones’ users. This Kit is designed for digital forensics units that undertake data extractions and undertake some basic analysis of the data contents.

What Is Included
The price of this kit includes the following:

  • a USB flash drive containing .bin files extracted from two different mobile phones that have been seeded with data: one from an Android smartphone and one from a simple feature phone
  • photographs of the two phones
  • detailed Instruction Sheet and Results Form
  • a report detailing an assessment of your submitted results for correctness or otherwise (for 1 participant)
  • an Inter-Laboratory Comparison report (providing there are a minimum number of participants)

To prepare a realistic and challenging mobile phone proficiency test our experts have undertaken extensive research. We have also met with and discussed the issues of preparing this PT with external specialists, a mobile phone manufacturer, police force digital forensic units and Home Office specialists, including those at CAST. Unfortunately, we have not yet found a practical way of copying data from one seeded handset to other handsets (in order to produce identical handsets to distribute to participants). Therefore, we have designed our Mobile Phone PT kit around this situation enabling us to still test processes in digital forensics’ units / organisations. The results from this Round will also produce a very valuable Inter-Laboratory Comparison report, which we will anonymise and distribute to all participants.

We are still exploring the possibilities, with several different specialists and organisations, of producing individual, reproducible, seeded mobile phone handsets, in order to provide a “specialist” Proficiency Test in due course.

This is an On Demand Round – please contact FPTS for more detailed information.

Our Report
Once we have assessed a customer’s results we will send back a report, by email, in PDF format, which will contain the following:

  • assessment of the results
  • additional comment as necessary

Additional Advice
We do not offer Additional Advice during this Pilot Phase.

Other Information
The mobile phones used in the preparation of this Proficiency Test were seeded under controlled conditions, with every operation logged for date, time, location, etc. The data extracted from the phones has been subjected to a carefully designed validation plan. The data was extracted by digital forensics experts whose organisation is currently seeking ISO 17025 Accreditation for their digital forensics work.

ISO Quality Accreditation
Forensic Access has been accredited to ISO /IEC 17025 since 2010 and ISO 9001 since 2004.

To provide you with the best possible Proficiency Testing service we are currently seeking accreditation to “ISO/IEC 17043:2010 Conformity assessment — General requirements for proficiency testing”. Initially this will be for Body Fluids and Fingerprints but we intend to extend our scope to include the Digital Schemes later this year.

Collusion and Falsification of Results
FPTS will do what it can, in the design and operation of its Proficiency Testing Schemes, to be alert for any indication of collusion or falsification of results.

However, we must stress that it is the responsibility of participating laboratories not to engage in any way in collusion or falsification of results. Laboratories found to be engaging in such activities may be refused participation in subsequent Proficiency Testing Rounds.

If you are accredited to a Quality Standard, such as ISO 17025, your accreditation agency may also scrutinise your participation in Proficiency Testing schemes for any evidence of collusion during their audits. They may also investigate whether a participant is applying greater efforts when undertaking the PT than would be normal in everyday casework.

However, FPTS will scrutinise all results from participants for any evidence of collusion or falsification of results and investigate any suspicious occurrences.
