A Method of Concealing Email Address Based on Cryptographic Algorithm

Abstract

The invention discloses an email address concealing method based on a cryptographic algorithm. An email address together with inherent features of the email address are encrypted by using a Web / Servermode and the Playfair cryptographic algorithm, so that the encrypted ciphertext obtained after encryption is a string of characters, the inherent feature of the email address is not stored at all, thereby achieving the purpose of concealing the email address and effectively preventing the email address from being crawled. According to the email address concealing method disclosed by the invention, the manner of improving the intermediate Server can be adopted, the Serve maintains a mapping table from the email address of a user to the corresponding ciphertext, and when user registers the email address, the email address and the corresponding ciphertext are stored, thereby improving the communication efficiency. The method disclosed by the invention is simple and easy to use, low in cost and high in security.

Description

technical field [0001] The invention belongs to the technical field of information security and relates to a method for concealing mail addresses, in particular to a method for hiding mail addresses by using a Playfair password mechanism. Background technique [0002] Email is an indispensable means of communication, and email addresses can be posted to the Internet by individuals. In the use of email mailboxes, it is necessary to prevent web crawlers and reduce spam; it is also easy to recognize by human eyes without affecting normal use. Spam generally refers to any mail sent to a user's mailbox without the user's permission. People's email addresses are published on the Internet, and there are many crawler programs that can be used to crawl email addresses. Once they are crawled, many spam emails will appear in the mailbox. [0003] At present, there are mainly two ways to effectively reduce spam: one is to block from the end, such as: honeypot, Bayesian spam filtering ...

AI Technical Summary

Problems solved by technology

This method can effectively fight against web crawlers, but it is not conducive to plain text editing and modification

[0005] It can be seen that the problem with the existing means of resisting web crawlers from crawling email addresses is that the algorithm is too simple and retains the inherent characteristics of email addresses, which provides convenience for web crawler technology to identify email addresses, and it is difficult to effectively fight against web crawlers
