  • Computer Forensics Investigations

    Computer Forensics combines the fields of Computer Science and Law. Our experts preserve, analyze, and report on the digital evidence found on computer hard drives, USB devices (thumb drives and external hard drives), online data storage (i.e. Dropbox, Google Drive, and OneDrive), and online email services (i.e. Gmail and Yahoo email).

  • Cell Phone Forensics Investigations

    Cell Phone or Mobile Device Forensics consists of the extraction, preservation, analysis, and reporting of data located on mobile devices in a forensically acceptable and court approved process. TRC can examine more than 9,500 different types of cell phones and tablets, including the most popular devices on the market, the Apple iPhone and iPad, and Android-powered smartphones.

  • e-Discovery

    The duty to preserve Electronically Stored Information (ESI) begins when litigation is reasonably anticipated. TRC has the unique advantage of having worked on behalf of both plaintiffs and defendants. We have served as a "Neutral Expert for the Court" on multiple Electronic Discovery cases. Ask about our distinctive process known as "Forensics e-Discovery."

Mr. Broom has been qualified as an Expert Witness multiple times in state and federal courts, in civil as well as criminal cases.

  • Evidence Preservation

    At times, simply preserving evidence for potential future litigation may be all that is necessary. TRC specializes in large collections (over 50 computers) but can assist with any size forensics preservation. Windows based computers, Apple Mac devices, and mobile devices (cell phones and tablets) can be collected, forensically preserved (including Chain of Custody documents), and returned to service quickly and professionally.

  • Data Recovery

    Corrupted Operating System? Deleted photographs? Lost data? Our technicians can restore data from damaged computer hard drives, cell phones, and USB devices and get you back to work quickly. Data Recovery can be a cost effective method to restore damaged devices as opposed to recreating business data and sometimes it can be the only solution to recover the lost memories found in deleted photos.

Computer Forensics FAQs


What exactly is Computer Forensics?

Computer Forensics is the use of specialized techniques for the preservation, identification, extraction, authentication, examination, analysis, interpretation and documentation of digital information. Computer forensics comes into play when a case involves issues relating to the reconstruction of computer system usage, examination of residual data, authentication of data by technical analysis or explanation of technical features of data and computer usage. Computer Forensics requires specialized expertise that generally goes beyond normal data collection and preservation techniques available to end-users or system support personnel.

What is Chain of Custody/Chain of Evidence?

Chain of custody is the record of the custodial history of evidence. The Chain of Custody shows, "WHO had access to WHAT and WHEN did they have it."

Chain of Evidence or authentication is the record of the collection, processing, and analysis of digital evidence. It proves that the presented evidence is unequivocally derived from the acquired digital information.

What is a Forensics Image?

A forensics image (sometimes called a forensics copy) is an exact bit-by-bit copy of a digital device (hard drive, USB device, cell phone, etc.) including active data, slack space, unallocated space (or unused space). We use court approved forensics tools for making these images. Our tools produce authentication information, called a hash value, to ensure the integrity of the image.

What is a hash value?

A hash value is a mathematical algorithm produced against digital information (i.e. a file, a physical disk, or a forensics image) thereby creating a digital fingerprint for that information. It is by purpose a one-way algorithm and thus it is not possible to change digital evidence, without changing the corresponding hash values. In other words, if the hash value of a file has not changed, the file itself has not changed.

A hash value, commonly referred to as an MD5, SHA-1, or SHA-256 hash (based on the algorithm used to produce the hash) is used to authenticate digital evidence.

MD5 Hash Example: e6196e1b4f0d1535244eaab534428542

What is the difference between Computer Forensics and Digital Forensics?

Generally, the concepts overlap, however digital forensics may be the more contemporary expression and more inclusive, recognizing forensics services directed at more types of devices besides those that have been traditionally considered computers, such as cell phones, landline phones, cameras, sound recorders, personal digital assistants, networks including the Internet and others.

How much do computer forensics investigations typically cost?

The cost of a computer forensics investigation varies greatly, depending on the number and types of systems involved and the complexity of the evidence recovered. Technical Resource Center knows how to ask the right questions to obtain an accurate quote for your investigation.

A complete examination of a single Terabyte hard drive may have over 200,000,000 pages of electronic information and may take between 15 to 100 hours to examine, depending on the amount of data, types of data, condition of the media and data, and the questions to be answered.

A reasonable quote can be obtained prior to the start of the examination if complete and accurate information about the systems is available to the examiner and the scope of the examination is clear (i.e. the questions that need to be answered). This time could increase or decrease, depending upon the type of operating system used, the type of data contained within the system, and the size and amount of data in question.

At Technical Resource Center, our examiner's hourly rate is $350. In most instances, examination and reporting can be completed in less than 20 hours and the complete analysis usually totals less than $7,000 for a single hard drive.

We do NOT charge an hourly rate for equipment operation time (i.e. when our personnel are not actively involved processing evidence, but only periodically monitoring the processing). Some firms charge extra for the use of their computer hardware to process evidence.
