Abstract: The present disclosure provides a security verification method and a relevant device, to increase the difficulty of cracking. The method includes: receiving, from a verification requester, a request for pulling a sliding verification code; acquiring the sliding verification code which includes a slider and a second endpoint image obtained by performing filter processing on a first endpoint image; and returning the sliding verification code to the verification requester. The first endpoint image and the slider are generated from the same original image, and the slider and the second endpoint image are returned to the verification requester finally. The second endpoint image is obtained by performing image processing on the first endpoint image, and after the image processing, in an area outside the slider placement area, pixel values of pixels in the second endpoint image are different from pixel values of corresponding pixels in the original image.

Abstract: Provided are a display panel and a display device. The display panel includes a light-transmissive region, a display region at least partially surrounding the light-transmissive region, and a non-light-emitting region located between the light-transmissive region and the display region. In the radial direction of the light-transmissive region, the difference in the size of the non-light-emitting region located around the light-transmissive region is ?D, where 0 ?m?|?D|?10 ?m.

Abstract: Embodiments of this application disclose a website attack detection and protection method and system performed by a computing device, applied to the field of information processing technologies. In the method in the embodiments, the computing device calculates a parameter value of an information aggregation degree parameter corresponding to each field included in a header of a request for accessing a website, and then determines, according to the parameter value or a variation degree of the parameter value of the information aggregation degree parameter of the field, whether the website suffers a Challenge Collapsar attack.
