imagetamperingdetection

An Image Tampering Detection and Localization using MATLAB. Here image tampering is majorly detected by ELA (Error Level Analysis) by identifying the areas where there are different compression levels. Original Picture is roughly at same compression level but a digitally modified image is at different compression levels. Using Lowpass filter that is weiner2 noise is removed from ELA output and using tophat and bothat contour of tampered is region is reconstructed by Morphological structuring.

metadata_mapping_exif_data-475-2151_rojas_schoenfeld

Mostly all pictures, videos, documents taken with a smartphone, or created with a computer will have metadata associated with it.  Some of this metadata allows us to create maps and timelines of where these pictures were taken.  Using ExifTool, we can scrape out GPS coordinates from pictures and documents then using an API we can plot these coordinates in Google Maps or some similar mapping program.  This can help forensic investigators and law enforcement identify the location of interesting places in an investigation or show the origin in which a file was created.
