Embodiment Construction

[0054]An embodiment of the present invention provides a method for downloading a file, which includes: when a user end initiates a file download, first submitting a Uniform Resource Locator (URL) to a server. The server looks up the content identification of the file corresponding to the URL in the mapping table according to the URL, then judges whether the file is a compound file according to the content identification, if not, obtains the security information of the file through the content identification, and if so, obtains the security information of the file from The content identifiers of the subfiles included in the file are obtained from the subfile mapping table, and the security information of all subfiles is obtained through the obtained content identifiers, and the files are downloaded according to the security information.

[0055] Such as figure 1 As shown, the embodiment of the present invention is a method for reporting security information, which specifically ...

Abstract

The invention discloses a method for downloading a file and a system thereof, and aim at solving the problem that security information provision is incomplete in the prior art. A method for providing the security information comprises the following steps: a server terminal receives a uniform resource locator submitted by a user terminal at file downloading, obtains a content identification of the file according to the uniform resource locator, then acquires the security information of the file according to the content identification, and finds out the security information of a subfile which is contained in a composite file according to the content identification when the file is the composite file, and finally provides the security information of the file and the security information of the subfile to the user terminal. The scheme provided by the invention can help a user to acquire the security information of all files before downloading the files.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method for providing file security information and a security information processing system. Background technique [0002] At present, files available for download on the Internet include ordinary files and compound files. A compound file is also called a pan-compressed file, specifically referring to a large file formed by organizing several files together according to certain rules. In the process of organizing compound files, there may be a series of operations such as compression and reorganization. For example, compressed files, installation packages, etc., all belong to the compound file type. [0003] When a user is downloading a file, many server providers often pre-store information on whether the file is safe on the server. For example, for file A, the server stores the security information of A, and when the user requests the server to download file A, the ser...
