Analysis Method of Digital Forgeries on the Filtered Tampered Images
— Digital forensics is the emerging research field for determining digital forgeries. Key issues of the tampered images are to solve the problems for detecting the interpolation factor and the tampered regions. This paper describes a method to detect the interpolation factors and the forged maps using the differential method and fast Fourier transform (FFT) along the horizontal, vertical, and d...
متن کاملCSCI 6270 COMPUTATIONAL VISION PROJECT Exposing Digital Forgeries in Complex Lighting Environments
The increase in sophistication of image manipulation software such as Adobe Photoshop, coupled with improvements in imaging algorithms, has given rise to digital forgeries that are very hard to detect. My project here is based on the paper ’Exposing Digital Forgeries in Complex Lighting Environments’ [4], wherein the authors detail a technique to identify digital forgeries via inconsistencies i...
متن کاملDetecting timestamp forgery in NTFS file system using logfile
In the current era of digital world, user and investigator are more dependent on digital data. Digital data are very vast in size and also stored in various formats. So, the major problem is identification of upcoming data as true or false by the user or investigator. To overcome this problem different methods and techniques are adapted. Forensic method is used for validation of data. A compute...
