This software enables the authentication of an image captured by the camera and can determine whether or not it has been altered since capture. Image data can be used as a critical link in the chain of evidence for verifying image authenticity by law enforcement and government agencies, the media, insurance companies and for a variety of other business applications. The software enables verification of JPEG, TIFF and NEF (RAW) data taken using a Nikon digital SLR compatible with the authentication function.
