Problems solved by technology

Even if some addresses and domain names have been set accordingly, in many cases, some recipients do not explicitly reject emails that do not comply with SPF or DKIM settings. Therefore, it is still difficult to confirm the identity of the email sender with these mechanisms alone. believable

Embodiment Construction

[0189] The first embodiment of the present application provides a method for identifying the identity of an e-mail sender. The method is used to identify whether the e-mail sender has a real identity. When an e-mail is transmitted between two different e-mail systems , the recipient system needs to screen and verify the authenticity of the domain name identity of the sending address of the received mail to determine whether the received mail is indeed from the email system authorized by the domain name owner, or to determine whether the Whether the received email is sent from the email sending IP address authorized by the domain name owner, further this method can identify suspicious emails sent by forging or pretending to be someone else's domain name.

[0190] Among them, the e-mail system is a separate system, which has its own server. Multiple domains can be set up in the e-mail system, and multiple users can be set up in each domain. For example, if you buy a The commerci...

Abstract

The invention discloses a method and device for discriminating an identity characteristic of an e-mail sender. According to the method, a preset characteristic matching model is established; matching condition judgment is carried out on an extracted to-be-discriminated characteristic in a preset characteristic set by taking the preset characteristic matching model as a judgment basis; and when the corresponding characteristic in the preset characteristic set satisfies a characteristic matching condition, it shows that an to-be-discriminated identity of an e-mail sender is true and credible. According to the method provided by the invention, the email sender does not need to carry out setting of any aspect, email sending behavior information is collected and compared, and the identity characteristic of the e-mail sender is matched and discriminated according to the information. Through application of the method, whether the identity of the sender is true and credible or not can be accurately confirmed.

Description

technical field [0001] The present application relates to the technical field of email systems, and in particular to a method and device for identifying identity characteristics of email senders. Background technique [0002] Due to the development of network technology, traditional communication methods are almost replaced by network communication methods. For example, the emergence of email has gradually replaced traditional letter transmission. In the era when the Internet is popular, users are more inclined to use email as a transmission method to transfer files and information no matter in life or work. [0003] According to the e-mail protocol, when an e-mail is transmitted in the same e-mail system, both the receiver and the sender need to use passwords and other methods for identity authentication when logging in for the receiver and sender to use the same e-mail system , Therefore, if the receiver and the sender use the same system, the sender needs to pass the ide...
