OVERVIEW

With the rise in availability of free and low cost photo editing software packages, the editing of images is more prominent than ever before. Authentication by a Forensic Imagery Expert can detect edits and manipulations made to photos from a variety of sources, including mobile phones, cameras and social media.



Types of cases

We perform authentication of photos in all sectors including for use in criminal and civil trials, family court, workplace disputes and private matters.

As our duty is to the court and not the instructing party we can perform work on the instruction of both prosecution and defence, and can offer rates that meet those of the Legal Aid Agency accordingly.


Types of Photos

We can perform authentication examinations on all digital photos, regardless of the capture method or format, including:

  • Photos taken with a digital camera

  • Stills from CCTV video recordings

  • Mobile phone photos (from all models, including iPhone, Samsung, Nokia)

  • Stills from Body Worn Camera video recordings (for example those worn by Police or Bailiffs)

  • Social media photos

types of manipulation


As we use a variety of techniques, each devised to identify a different trace left by the photo editing / photoshopping process, we can detect a variety of manipulations, including:

  • Deleted sections / Removal of sections

  • Cloned sections

  • Replaced sections

  • Photos purported to be from a different device

  • Changes to capture date
