Abstract

The invention discloses a method and a device capable of verifying e-mail sending time. The method capable of verifying e-mail sending time comprises the following steps: sending an e-mail to at least one e-mail receiving client, requesting to acquire trusted timestamp of a third timestamp server, judging whether the trusted timestamp is acquired, if yes, signing the trusted timestamp through a digital certificate of an e-mail sending client and adding the signed trusted timestamp to a header of the sent e-mail. With adoption of the method, accuracy and reliability of the e-mail sending time are guaranteed, and verification is facilitated.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device capable of verifying the sending time of an email. Background technique [0002] At present, e-mail has become an inseparable communication tool in work and life, especially various work e-mails, and the content in e-mail has also been used as a kind of electronic evidence in various litigation cases. Commonly used email client software such as Microsoft Office Outlook, Tencent QQ mailbox and Foxmail automatically read the user's computer time as the sending time of the email, and the sending time of the email is the time of the sender's computer or mobile terminal. Every time the system operates on the mail, it only adds a standard time with a small error, such as the read network time. The sender or recipient of the email can modify it at will, that is to say, the sending time of the email is unverifiable and untrustworthy. The encryption behavior of...
