There are many more advantage of using JPEGSnoop which I will come out explaining in a post soon. Overall an excellent software which you can download from here and check anytime if claimed original images are actually original.

MOV – QuickTime Movies, QTVR (Virtual Reality / 360 Panoramic).

THM – Thumbnail for RAW Photo / Movie Files.

In case the image is edit you can add that too. In case the image compression is not determined because the camera is pretty new, you can always update the data from the tool.

JepgSnoop Indicates if Original image was edited Original Image taken from canon 850 This is one of the result sample when I tried it on original image. Thus if the compression signature doesn’t match against Camera signature but photoshop compression signature you know that it might have been tampered. JEPGSnoop is a free software which has a huge internal database that compares an image against a large number of compression signatures. This way a lot of factors can be determined including the camera from which it was taken ( using EXIF data ). The trick is every time an image is saved using a software a signature is also saved along with the image. Many a time if you find an image which is claimed to be taken from a camera and being displayed without any editing or tricks ( which can be done by using photoshop like software ), JPEGSnoop can find if it is original or not.
