Digital tampering
Digital tampering , from to tamper , is a technical term for analog and digital photo manipulation . The expression is derived from the criminal offense of influencing the court (jury tampering), so it means in general a deliberate influence on the judgment.
Digital tampering has been raised in the public's awareness through the manipulated images of the 2006 Lebanon war distributed by the Reuters agency. For this reason, the agency took 920 digital recordings from a freelancer from the mailing list.
There are several methods of determining image forgery. The simplest is the image comparison, in which, however, the still unchanged templates or comparable image sources must be available.
Other methods examine the digital pixel distribution using statistical methods and thus track down the forgery.
