Problems solved by technology

Due to the reasons of the HTTP communication protocol itself, in the method of preventing hotlinking, judging the header information cannot truly prevent hotlinking

Embodiment 1

[0012] 1. Use MyEclipse as a development tool, use the database management tool MySQL to build the database and tomcat server required by the system.

[0013] 2. On two servers, one acts as a front-end server for external access, and encrypts the access address according to the access content; the other deploys the source program, and acts as a response server to decrypt the access content.

[0014] 3. After the front-end server receives the access information, it first encrypts the access address, and then submits it to the response server.

[0015] 4. On the responding server side, first decrypt the received access address and restore the access information. At this time, it is necessary to judge whether it is legal or expired.

[0016] 5. If it is illegal or expired, it will return to the front-end server, prompting illegal access, otherwise, it will return the content actually accessed by the user.

Abstract

The invention relates to a method for encrypting a URL (uniform resource locator) address in order to prevent a public network user from counterfeiting a URL address, preventing an unauthentic Frontend Server from counterfeiting an address and preventing overdue URL address accessing. Various methods for preventing content hotlinking such as pictures in a website are provided, and the most common method is that an access source is judged according to HTTP (hyper text transport protocol) access head information; readers understanding TCP / IP (transmission control protocol / internet protocol) communication all know that HTTP head information processing is executed on an application layer of an OSI (open system interconnection) model, so that some pieces of false HTTP head information are compiled and sent to a server without special technologies or tools. Prevention of hotlinking according to the HTTP head information is a typical method for preventing a gentleman not a black man, and the security problem can be thoroughly solved by URL address encrypting only.

Description

technical field [0001] The invention relates to a URL address encryption method. The invention belongs to the field of computer technology. Background technique [0002] An "interesting" URL exploit has been discovered by spammers for a long time, but now the "KB" (Knowledge Base) spoof and the article published in Crypto-Gram in February have allowed URLs to do more thing. Although most Internet users associate WWW addresses or FTP with URLs, Uniform Resource Locators (URL, Uniform Resource Locator) are more commonly used. A resource server can not only be exposed to the public network environment, but also ensure that it only accepts and processes trusted http access requests. The WEB content facing the network is public, and in most cases, there is no need to consider hotlinking. If you want to restrict certain content, only for browsing by a specific group of users, you can use CGI for user authentication. For example, SNS, forums, and WEB mailboxes all have this fu...
