The first comprehensive and detailed presentation of techniques for authenticating digital images.Photographs have been doctored since photography was invented. Politicians have manipulated photos for short-term political gain. Dictators have erased people from photographs and from history.
Today, powerful and low-cost digital technology makes it relatively easy to alter digital images, and the resulting fakes are difficult to detect. Altering photographs in the predigital era required time-consuming darkroom work. The field of photo forensics--pioneered in Hany Farid's lab at Dartmouth College--restores some trust to photography.
In this book, Farid describes techniques that can be used to authenticate photos. He provides the intuition and background as well as the mathematical and algorithmic details needed to understand, implement, and utilize a variety of photo forensic
