Description

technical field [0001] The invention relates to the technical field of information security, in particular to a light-weight image file disk encryption system and method. Background technique [0002] An image file is actually an independent file. Unlike other files, it is made from multiple files through burning software or image file creation tools. Image files have a wide range of applications, and the most common application is data backup (such as floppy disks and CDs). With the popularization of broadband networks, some download websites also have files in ISO format for downloading, which facilitates the production and delivery of software CDs. Mirror files can save and back up our videos, pictures, files, etc., so that when the files themselves are damaged, the same files as the original files can still be copied to prevent the loss of important files. But also because of this advantage of the image file, it can copy the content in the image file under certain cond...

AI Technical Summary

Problems solved by technology

But also because of this advantage of the mirror file, it can copy the contents of the mirror file under certain conditions, which also makes the security performance of the source file itself have certain security risks.

For example, the audio of a singer’s original album is the most common case. Criminals often use special means to tamper with the audio of their original album, burn it into a pirated CD, and then sell it at a low price, which seriously affects the normal distribution of genuine CDs. , so that the sales of singers and record companies are seriously affected

What is more common is that in order to save important files, the company will back up important files, and this backup file is easy to be stolen and used by criminals, and then the important files inside the company will be leaked, leading to serious consequences
