| description | Developing methods aiming at identification of digital images integrity violation is an important problem of complex system of information security. Cloning method, realized in the most of graphic editors, is often used to compromise the integrity of the image related to unauthorized changes. Therefore, the task of cloning identification is a relevant one. In addition to the cloning identification it is also important to clarify the contours of the cloned area. In this paper we propose a polynomial comprehensive method to identify areas of cloning as a falsification of the digital image. It allows to locate the cloned areas with a higher precision compared to modern analogues. Complex method is based on two modern clone detection techniques, using a common approach to the analysis of the state and technology of the information system functioning. It includes two stages: “fast rough” cloning area identification and a “slow” identification of the contour of the cloning area using a limited image subarea containing a clone. The method proposed can be adapted for the digital video. |
