1. A method for detecting JPEG compression comprising: selecting a bitmap image; performing JPEG compression with a Q-Factor (QF) of 100 on the bitmap image; selecting AC JPEG coefficients from the compressed bitmap image; computing a 1 st digit distribution of the AC JPEG coefficients; analyzing the AC JPEG coefficients to determine whether the AC JPEG coefficients satisfy a predetermined distribution; determining the bitmap image as JPEG compressed when the JPEG coefficients do not satisfy the predetermined distribution; and determining the bitmap image as at least one of not JPEG compressed and JPEG compressed with a QF=100 when the JPEG coefficients satisfy the predetermined distribution.
