Smartphone camera identification from low-mid frequency dct coefficients of dark images

HIGHLIGHTS

• who: Adriana Berdich and Bogdan Groza from the Faculty of Automatics and Computers, Politehnica University of Timisoara, Timisoara, Romania have published the Article: Smartphone Camera Identification from Low-Mid Frequency DCT Coefficients of Dark Images, in the Journal: Entropy 2022, 24, 1158. of /2022/
• what: The analysis showed that the blue channel provided the best separation which is in contrast to previous works that have recommended the green channel for its higher encoding power. Since CMOS sensors are low power and less expensive than CCD sensors , the majority of smartphones are equipped with CMOS sensors . . .
