The invention relates to a continuous data protection method based on a jump recovery chain, which belongs to the technical field of computer storage and aims at reducing the data recovery time of continuous data protection and improving the performance of writing operation and data recovery. The algorithm includes a write operation algorithm and a data recovery algorithm, and adopts the jump recovery chain technology to ensure that the system can recover to any point in time before the failure in a short period of time without inserting a snapshot, that is, the data recovery time and recovery point time The span is irrelevant, effectively solving the problem of fast recovery of long-term data; at the same time, data buffering technology is used in the write operation algorithm and data recovery algorithm to improve the write operation performance and data recovery performance of the jump recovery chain.

A malicious URL detection method, apparatus, and storage medium are provided. The method includes rolling back a virtual machine to an initiating state in response to detecting a trigger event of the virtual machine. In the initiating state, page content of a target URL is loaded using the virtual machine. Using the virtual machine, an application program linked to the page content is run. A system snapshot file of the virtual machine is obtained in at least one state of the initiating state, a state in which the loading of the page content is completed, or a state in which the application program is being run. Malicious URL detection is performed on the target URL based on the obtained system snapshot file.

The invention discloses a motor vehicle snapshot method, a motor vehicle snapshot device and a computer storage medium, and the method comprises the steps: obtaining a real-time monitoring image, obtaining motor vehicle information and non-motor vehicle information in the real-time monitoring image, extracting motor vehicle key points of a motor vehicle based on the motor vehicle information, and storing the motor vehicle key points in the computer storage medium; non-motor vehicle key points of the non-motor vehicles are extracted based on the non- And when the position relationship between the motor vehicle key point and the preset motor vehicle snapshot line meets a first snapshot condition and the position relationship between the non-motor vehicle key point and the preset non-motor vehicle snapshot line meets a second snapshot condition, capturing a motor vehicle image in the real-time monitoring picture. According to the motor vehicle snapshot method, the snapshot line is preset on the real-time monitoring picture, the target motor vehicle in the real-time monitoring picture is subjected to real-time snapshot according to the relative distance relation between the key point positions of the motor vehicle and the non-motor vehicle and the snapshot line, and the snapshot effect of high capture rate and accuracy can be achieved.

The present disclosure relates to a distributed transaction processing method and device, and a computer storage medium. The processing method of the distributed transaction includes: receiving a business request initiated by a user, and the business request includes multiple write operation requests; creating a global transaction according to the business request, and assigning a first identifier to the global transaction; encapsulating each write operation request into a branch transaction, and assign a second identifier to each branch transaction; for each branch transaction, from the database corresponding to each branch transaction, query the original data before executing each branch transaction, and generate the corresponding original data in memory of the first snapshot data; for each branch transaction, in memory, execute each branch transaction on the first snapshot data to generate the second snapshot data; in response to the request initiated by the user to submit the global transaction, the The second snapshot data is written into a database corresponding to each branch transaction.
