SM-920C Thumbnail Image file  

New Member

I am working on a Samsung SM-N920C device that I was able to collect data from the phone using Cellebrite (Physical Extraction).

I am trying to investigate some pictures, which are in thumbnails. The pictures are not available elsewhere?

The pictures locations are "Media/0/DCIM/.thumbnails/1512492855362.jpg"

I need to know from where this pictures came from?

The picture is taken by Camera or not? No metadata is available, Second can we define any relationship between original picture and thumbnail picture?

i means is there any chance to get original picture name and timestamp.

Does anyone have any thoughts on the picture and its location?

I'll try to help


1) Media/0/DCIM

This is the default storage area for images taken by the device camera.


Once an image taken by the camera is taken and is stored in the default location the Android OS creates a Thumbnail of the image in the above path (Media/0/DCIM/.thumbnails/)

The thumbnail is given a UNIX epoch time stamp (milliseconds) name

as in 1512492855362.jpg

This converts to 05/12/2017, 165415 GMT

If the original images has been deleted or moved the thumbnail will remain in the thumbnail folder(Media/0/DCIM/.thumbnails/)

However without the original Image this is a very basic interpretation of the remaining data

Kind regards

You original file was deleted, renamed or moved. Do it the other way around, carve for all images, even if partial, then do a match on the time stamps to figure the original file. I would also check the content of any memory cards used in the device, if available )
