Smartphone Camera Identification from Low-Mid Frequency DCT Coefficients of Dark Images

Smartphone Camera Identification from Low-Mid Frequency DCT Coefficients of Dark Images

Camera sensor identification can have numerous forensics and authentication applications. In this work, we follow an identification methodology for smartphone camera sensors using properties of the Dark Signal Nonuniformity (DSNU) in the collected images. This requires taking dark pictures, which th...
