Website tamper-proof system and a method based on a block chain

Abstract

The invention discloses a website tamper-proof system and a method based on a block chain. The method comprises the following steps: all web page files of a website are calculated by using a hash fingerprint generation algorithm to obtain a corresponding hash fingerprint; the hash fingerprint and the web page files are respectively written into a source data preservation module based on a block chain; the source data preservation module stores the hash fingerprint and the web page files in a block chain form; and the web page files are automatically written into a web site directory of a web server; periodically polling the web site directory, obtaining the web page file and the hash fingerprint of the web page file from the web site directory and the source data preservation module respectively, utilizing the obtained web page file and the hash fingerprint and the tamper determination algorithm to determine whether the web page file is tampered with or not; If tampered with, notify the publisher to get the correct web page file from the source data security module and write it to the site directory. The invention effectively improves the safety and reliability of the webpage, andensures the safety of the personal information and the property of the user.

Description

technical field The invention relates to the fields of computer technology and cyberspace security, in particular to a blockchain-based anti-tampering system and method for a website. Background technique Website refers to a collection of related webpages displaying specific content on the Internet, usually responsible for information release, administrative approval, public service, e-commerce, social networking and other functions, and is the entrance of a series of information systems. A single web page is a plain text file containing HTML tags in Hypertext Markup Language format. Web pages are generally divided into static web pages and dynamic web pages. Static web pages, whose content is predetermined and stored on the web server or local computer / server; dynamic web pages, are pages created based on the parameters provided by the user and based on the data stored in the background database. Modern webpage production often uses scripting languages ​​such as PHP, Rub...

Problems solved by technology

However, since the digital watermark itself is plain text, the watermark itself is easily tampered by attackers during storage and transmission without being noticed. Once the watermark is modified, the tamper-proof system will be completely invalid.

In addition, there is an anti-tampering method for webpages based on the operating system kernel, that is, based on the control of the operating system on the process to prevent other processes from operating on the target directory, but such protection measures depend on the operating system and are not easy to cross-platform, and tampering is easy to be done by someone. However, the traditional anti-tampering system for web pages only supports international cryptographic algorithms and is not compatible with domestic cryptographic algorithms

To sum up, the traditional anti-tampering system of web pages has certain security risks, and information security needs to be improved
