Problems solved by technology

[0002] At present, Flash is widely used in webpage design, webpage animation production and webpage video playback, etc. Most video websites, including live broadcast websites, use Flash as their video player, and most webpage games, most mailboxes, etc. Web applications use Flash to develop some functions. The specific file used for Flash is a SWF (ShockWave Flash) file. Flash has considered cross-domain from a security point of view at the beginning of its design (cross-domain refers to accessing another website under a website domain name. domain name data), because cross-domain access to some files or resources has the risk of movement, this process exceeds the scope of the website itself, and the security of resources outside the website cannot be audited
