It will be appreciated that the memory module 13 may record data generated by the computer running in real time, for example, the composition data of the monitoring programming software (such as java, c language). The storage module 13 may also obtain the operation flow codes so far according to the operation commands of the user, and generate corresponding trace files. For example, the operation sequence of the user through mouse selection function and software, keyboard typing and the like is recorded and converted into a corresponding text expression or video expression file (namely the trace file), so that the review of the user is facilitated, particularly the course teaching in a computer laboratory is facilitated, the trace file is generated, the later autonomous review of the user is facilitated, and the classroom teaching efficiency is improved.
Referring to fig. 2, the preset program further includes:
the image code scanning module 100 is configured to scan the corresponding two-dimensional code to obtain a corresponding two-dimensional code image;

It can be understood that, due to the interference effect of the wave between the photosensitive element of the camera and the display, a picture obtained by copying the image on the screen of a computer or a mobile phone will have obvious color fringes, which are called "moire fringes", and the moire fringes are high-frequency interference fringes appearing on the photosensitive element of a digital camera or a scanner, and are high-frequency irregular fringes which can make the image appear in color. The moire usually appears at the edge of the image, which causes the pixel gradient of the image in the region where the moire appears to be changed greatly, i.e. causes the non-linear change of the gradient value of the image surface. The reverse-copying module 200 may perform copy detection based on the pixel gradient of the image surface, for example, by extracting the statistics of the gradient feature of the image surface, and design an image classifier based on LibSVM to distinguish the copied image from the natural image. For another example, whether the current image is copied or not can be identified based on the surface features of the identification image, that is, whether the direct identification image has moire features or not.
