The increasing attention to continuous auditing in practice has demonstrated its significance as an important field of scholarly inquiry. This research takes the two wellknown continuous auditing systems, embedded audit module (EAM) and monitoring and control layer (MCL), to explore the key factors of successfully implementing a

In order to improve the capability of scrambling encryption and anti-aggressive, we extended the two-dimensional Arnold transformation to three-dimensional, and designed one kind of new diffusion equation of the digital image pixel gray value, then introduced a novel digital image encryption algorithm based on them. The large number of simulation results and analysis have both shown that the proposed scheme is a very effective encryption algorithm.
