Abstract: An order processing system is provided, including a first client (100), a second client (110), an order server (120), a resource manager (130), and a resource transfer server (140). The order server communicates with the resource transfer server through the resource manager according to a received order preprocessing request to complete transfer of a prepaid resource. Then the order server performs order settlement according to a received order settlement request or order cancellation request.

Abstract: An electronic transaction processing method, including: receiving a self-verification request, sent by a payee terminal, for an order transaction; and determining whether transaction verification information carried in the self-verification request matches verification information of the order transaction, wherein the verification information of the order transaction is sent to an associated payer account when the order transaction is successful; and if both match, not carrying out reversal processing.

Abstract: Disclosed are a service data processing method including: obtaining a first ordered dictionary tree and a second ordered dictionary tree, converting data of each of leaf nodes of the first ordered dictionary tree and the second ordered dictionary tree into binary data, and performing a comparison operation on the binary data of the leaf nodes at corresponding positions of the first ordered dictionary tree and the second ordered dictionary tree to obtain a difference between the service data of the first object and the second object.

Abstract: In a face detection method, preprocess an image, and extract corners from the preprocessed image. Then, filter and combine the corners to obtain a connected component for the corners. Extract a centroid from the connected component of the corners, and match the centroid with a facial template. Then, calculate a matching probability of the centroid with the facial template, and identify a region formed by centroids having a matching probability greater than or equal to a predetermined value as a candidate face region. With the method described above, the accuracy and efficiency of face detection can be improved. In addition, the present invention provides a face detection system and a computer storage medium.
