I want to work in Forensic Computing

Find out how you can start a career in forensic computing. Here we list potential job roles and some of the leading companies in that sector.

Job roles


Computer security is a fast developing area within Forensic Services. The work involves close contact with lawyers, commercial organisations and investigation agencies. Issues may involve fraud, child pornography, terrorism and ID theft.
Both mathematicians and computer scientists are recruited. There is a good market for penetration testing skills in finance, e-commerce and national security organisations.

Organisations involved

  • Police Forces.
  • Government Agencies (Customs and Excise, DTI, Serious Fraud Office)
  • Government intelligence services, including GCHQ
  • Specialist Forensic Computing firms
  • Software developers producing encryption software
  • IT security and corporate investigation companies
  • Large chartered accountancy firms
  • Banks and credit card companies

Where are the jobs?

  • Forensic IT
  • Computer security
  • Cryptology
  • Forensic accounting
  • Expert decision making systems (e.g. Fair Isaac Co)
  • Software development involving data compression and encryption or working with big data sets
  • Network software development in the telecoms industry
  • The computer games industry

Cryptography (also called cryptology) is the practice of hiding information.

Cryptography is used in:

  • Mobile phone companies such as RIM (BlackBerry) encrypt all e-mail messages
  • Banking (chip and PIN); secure online payment, security aspects of plastic cards: usually direct entry rather than through the graduate training scheme
  • The Internet (protecting transaction details using SSL and SSH)
  • Corporate computer security
  • Home computing (Windows and operating systems such as Linux contain cryptographic algorithms)
  • Satellite TV: Sky encrypts all its subscription channels.


Biometrics is the science of identifying humans based on a fingerprint, voice pattern, retinal scan or other bodily characteristics. Devices that use biometrics include fingerprint readers, voice pattern recognition, facial recognition and retinal pattern identification systems.
Identity fraud is rapidly increasing, driving forward the biometrics industry. Biometrics identification is inherently more secure than passwords and other identification methods: your password could be hacked, or your credit card stolen, but biometrics allows the system to know with certainty who is using it. Fingerprints have a long standing link with identity protection and are seen as a reliable way of identifying individuals. People are adding biometric readers to computers and theft-prone mobile devices to provide quick and easy system access.
Biometrics is most used in the field of security, to produce effective security networks and is becoming mainstream, proving itself as a convenient and secure method of user identification. It is likely to be a high growth area with a range of well paid new jobs.

Who employs biometricians?

The consumer market has the most potential.

What jobs are available for biometricians?

Biometrics involves many different technologies from optics to algorithms so jobs are available to grads in many IT fields including:

  • Software engineers
  • Security architects
  • Artificial intelligence
  • Computer vision
  • Device drivers
  • Mathematics
  • Hardware technicians to diagnose and troubleshoot biometrics readers in the field.
  • There are also jobs in sales support, marketing, product management and product development.
