According to an embodiment of the present application, there is provided an image verification method and apparatus, an electronic device and a computer-readable storage medium, which can be applied to the technical field of network security and the field of image processing and recognition. The image verification method includes: displaying a first image portion and a second image portion, the first image portion being rotatable with respect to the second image portion, the first image portion and the second image portion being obtained by cropping an original image and rotating the cropped first image portion with respect to the second image portion; receiving an operation for rotating the first image portion; rotating the first image portion based on the operation; and determining whether an angle of the first image portion relative to the second image portion matches with the original image, in response to determining that the operation is ended.

The present invention discloses a method for detecting random access of User Equipment (UE), applicable to a mobile communication system consisting of at least one Base Station (BS) and a group of UEs; wherein the BS and the group of UE use a set of N (N is a positive integer) orthogonal or quasi-orthogonal pseudo-random sequence codes for UEs' random access. The method comprises: BS receiving a random access signal, and making correlation operation of the received signal with each pseudo-random sequence code in said code set successively to obtain a corresponding correlation result window; finding the maximum correlation peak in the correlation result window, and then dividing a correlation peak window and the front-side and rear-side windows thereof; setting one or more thresholds and comparing them with correlation results in the correlation peak window or in the correlation peak window and the front-side and rear-side windows; when conditions are satisfied, determining that the pseudo-random sequence code involved in the above correlation operation is the pseudo-random sequence code selected by the UE randomly accessed at the moment; thereby, detecting each randomly accessed UE.
