don't know where to post this, mods please move elsewhere if non relevent..

my client needs a software that could check authenticity of a digital photo sourcing from digital cameras. i'm not familiar with even one. i found veripic.com but is there anything that is already available locally?

the authenticity check should detect if the image had been photoshoped or tampered.. this is for a high level of security.. involving court evidence, police reports..

anybody knows about the exifr98?

The Exif image file format standard was established with the aim of realizing a common format for the image files used with digital still cameras and other related equipment, making these products more convenient for end users.

With the rapidly growing popularity of digital still cameras, there are increasing demands for file interchangeability, which will allow images captured on one camera to be viewed on another, or output directly to a printer. ExifR98 is a set of compatibility recommendations designed to meet such needs, by strictly defining the range of Exif application, and by setting out detailed rules for recording and playing image files not specified in the Exif format.
