Computer forensics is the process of identifying, preserving, extracting, and analyzing data stored on digital devices such as computers, laptops, and external drives. In private investigation contexts, it is used to recover deleted files, examine user activity, and document digital evidence in a manner that supports its use in legal proceedings or internal reviews.
Computer forensics is the process of examining a computer or digital device to find out what happened on it, who did it, and when. Investigators use specialized tools to recover files, review browsing history, and document activity that may not be visible through normal use. The goal is to produce reliable, documented findings that can be presented to attorneys, employers, or courts.
A spouse suspects their partner has been hiding communications or financial activity on a shared home computer, and they need documented evidence before filing for divorce. An employer believes a former employee copied proprietary files to an external drive before resigning, and needs to determine what was accessed and transferred. A business owner discovers that company devices may have been used to send fraudulent communications to clients, and needs a record of that activity for litigation purposes.
Licensed private investigators can legally conduct computer forensic examinations on devices they have been given proper authorization to examine, such as devices owned by the client or devices surrendered with written consent. Examining a device without legal authorization, such as a computer owned solely by another party, may violate federal and state computer access laws including the Computer Fraud and Abuse Act. Legal standards for authorization and admissibility vary by state, so clients are encouraged to consult with an attorney before initiating an examination.
How long does a computer forensics examination take, and what will I receive when it is complete?
The time required depends on the size of the device, the volume of data, and the specific scope of the examination, but most standard examinations take between a few days and two weeks. At the conclusion of the process, clients typically receive a written report documenting the findings, along with a forensic image of the device and copies of relevant recovered files. The report is prepared to support use in legal or HR proceedings, though admissibility is ultimately determined by the relevant court or authority.
Can computer forensics recover files or messages that were intentionally deleted?
In many cases, deleted files can be partially or fully recovered depending on how long ago they were deleted and whether the storage space has been overwritten by new data. Forensic tools can often retrieve fragments of documents, images, chat logs, and browser history even after standard deletion. However, recovery is not guaranteed, and the condition of the device and its storage media directly affects what can be found.
