For evidence-collection purposes, it makes sense that iPhones and email would be commonly expected to be acceptable forms of data acquisition since they are so heavily utilized in our modern society. However, sending images from iPhones is not always a forensically sound method for collecting image data, no research has been published specifically testing the validity of collecting digital evidence from Apple iOS via the native Mail application. Furthermore, because this method has not been targeted for forensic investigation, there has been a knowledge gap in this area in the scientific community.This research was therefore conducted to fill this knowledge gap in the forensic field. Images were collected from various iPhone models and emailed via the Mail application native to Apple iOS. All image data originating on the phones were extracted for analysis, along with the emailed images that were sent from these devices.Some analysis results were mostly inconclusive due to limiting factors, and further research is suggested. However, stream hash analysis and metadata analysis were completed so that conclusions could be made. These conclusions were that only the Actual image size email option could be relied upon as a forensically sound delivery method for images. Images sent as Actual size could be considered digital clones of the original images and can therefore be trusted when collected as evidence. This statement is contingent upon these images having the same image capture settings selected on the iPhones at the time of their capture as utilized in our testing environment. Any modifications to the camera settings could still alter images deeming them evidentiarily useless even if still emailed as Actual size.
