Veryfi'a Fraud API accepts images and inspects them in seconds for detection of traces of forgeries. The API returns a color code and a confidence score.
Response Color codes
Image has not been tampered with
Image "might be" tampered with so treat this one with caution
Image IS tampered with
Under the Hood Inspections
EXIF Data Check
eg. Every image contains EXIF information and any abnormalities (eg. Missing EXIF) are a sign of potential image tampering.
Grain Detail Inspector
Compression artifacts, inconsistencies in geometry (skews),
Eg. area changed will be flat while other areas will be skewed, inconsistent color palette in a squared area.
Remnants of deleted objects or jagged edges around the changed area eg. when magic wand is used.
Inspects arrangement of typefaces, point sizes, line lengths, line-spacing (leading), letter-spacing (tracking) & s[ace between pairs of letters (kerning).
Using a large data set of what a manipulated image looks like, Veryfi will make an assessment whether the image you submit fits that range.
