Abstract

The invention discloses a file scanning method, device and system, and relates to the technical field of information security. The file scanning method, device and system aim at achieving the efficient cloud engine electronic file searching and killing. According to the main technical scheme, when a file to be scanned is uploaded to a cloud server so that searching and killing can be conducted, a client-side can upload a segment, containing the file type, of the file first according to the indication of the cloud server, the cloud server analyses the segment to determine the type of the file, the position of the file segment uploaded by the client-side is determined according to the type of the file, the client-side is indicated to only send the file segment which may contain security problems to the cloud server according to the indication of the cloud server so that searching and killing can be conducted, and security of the file is confirmed. The file scanning method, device and system are mainly used for the cloud searching and killing process of the file.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a file scanning method, device and system. Background technique [0002] With the popularization of computer use, a new type of file - electronic file was born. Electronic files are generated and processed by electronic computers, and their information is recorded and expressed in binary digital codes, which are recorded in code form on magnetic tapes, magnetic disks, optical disks and other carriers, rely on computer systems for access and can be transmitted on communication networks. The security of electronic documents is of paramount importance. At present, the scanning and killing engines for electronic files are generally divided into local engines and cloud engines. Wherein, the local engine scans the electronic file locally; the cloud engine needs to upload the file to the cloud server, and the cloud server scans the electronic file. When using the cloud e...
