System and method for protecting original text of E-mailer during circulation of E-mail

Abstract

The invention provides a system and a method for protecting the original text of an E-mailer during circulation of an E-mail. The method includes: when an E-mail sending terminal receives the E-mail sent by a sender, N GUIDs (global unique identifiers) are generated according to number N of the receivers of the E-mail; one E-mail copy is generated for each receiver, and the N GUIDs are respectively copied and pasted to the generated E-mail copies; original text protection is set for each E-mail copy with the unit identifier; the E-mail copies with the unique identifiers are respectively sent to the E-mail receiving terminals of the corresponding receivers, and the unique identifiers and the information of the receivers of the E-mail copies corresponding to the unique identifiers are stored in a data center; when the receivers forward the received E-mail copies, the original E-mail text cannot be copied and modified by the receivers. The method has the advantages that the novel cloud E-mail using a dialog mode to display the related information set of E-mail circulation is used, a cloud calculation method different from the circulation modes of traditional E-mails is used, data redundancy generated during E-mail circulation is reduced effectively, the original text of the E-mailer can be protected, and the authenticity of the original text of the E-mailer is protected.

Description

technical field [0001] The invention relates to the technical field of e-mail security, in particular to a system and method for protecting the original text of an e-mail author during e-mail circulation. Background technique [0002] At present, email, as the most important information communication tool on the Internet, has been widely used. However, the following problems exist in the current network: when sending and receiving emails, a new email will be generated every time the circulation of emails with the same subject is sent and received, resulting in data redundancy. [0003] The existing e-mail protection is that the sender needs a password to access when sending to the recipient, and the recipient needs a password to access the e-mail. After entering the password, the e-mail content can be forwarded and modified, and the sender cannot control whether the original text is Copy changes. [0004] Therefore, it is very important to design a method and system for pr...
