Description
Technical Field
The invention relates to the field of electronic evidence, in particular to an electronic mail data processing method and device, which are mainly used for solidifying electronic evidence.
Background
In the internet era, electronic data is increasingly used as evidence for dispute cases. However, in most litigation cases, electronic evidence is stored and provided by the parties themselves, and since electronic data can be tracelessly tampered, falsified and forged, the authenticity of the electronic data is often questioned during court trial and certified, and thus cannot be trusted.
The e-mail is an important communication mode in electronic commerce and daily communication of people, is one kind of electronic evidence, and has the characteristics of easiness in fading, tampering and damage and the like. In legal practice, when a party submits an email as evidence to a court after a dispute occurs, it is difficult to identify and adopt the email because a judge cannot confirm whether the content of the email downloaded by the party is changed. Meanwhile, due to factors such as low counterfeiting technical threshold, network environment and the like, the notarization department can not ensure the objective authenticity of the certified email and can not accept the certification of the email in many times. Once disputes occur, such as loan, announcement, and confirmation of matters in the online transaction process, the email in the mailbox is simply used as evidence and is easily questioned, and the proof power of the email originally used as a convenient communication tool cannot be exerted. The eleventh article of the contract law in China determines that the e-mail carrying the character symbol content is in the form of a book certificate, but the e-mail is used as the book certificate and should be submitted as the original or lacks evidence effectiveness. The notarization mechanism is used as a third-party mechanism to conduct certain notarization behaviors on the electronic mails and fix the notarization behaviors as written notarization materials, and the problem that the electronic mails are used as carriers to be shown is solved. However, only relying on the operation of notary, on one hand, the efficiency is low and the labor cost is high; on the other hand, there are problems such as artificial errors and blind spots.
How to fix the evidence with safe and effective electronic evidence to realize effective notarization of the e-mail, so as to improve the credibility of the electronic evidence and effectively guarantee the legal rights of electronic business parties and other netizens is a problem to be solved urgently.
