Method and system for constructing electronic evidence

Abstract

The invention relates to a method for constructing an electronic evidence. The method specifically comprises the following steps: generating a unique length-fixed digital abstract for electronic data of an applicant, and constructing a Merkle tree of an electronic evidence block chain system; constructing the electronic evidence block chain system with a timestamp; and setting an index number for a block by the electronic evidence block chain system, and returning the index number, the generated digital abstract and the timestamp to the applicant together. According to the method and the system disclosed by the invention, all participating parties can construct jointly, maintain jointly and supervise jointly, thereby meeting the right to know and the supervision right of each party; the identification cost of the electronic evidence is reduced, the identification efficiency is improved, and the objectivity and the reliability of the electronic evidence are enhanced.

Description

technical field [0001] The invention relates to a method and system for constructing electronic evidence on the Internet, in particular to a method and system for constructing electronic evidence based on block chains and time stamps. Background technique [0002] One type of electronic data is to prove the "objective existence of electronic data". As a kind of "objective existence", this type of electronic evidence needs to effectively prove the existence of "who", "when" and "what content". With the rapid development of people's use of the Internet and information consumption, electronic evidence is increasingly being used as recognized evidence in court trials or among the people. When it is necessary to prove the existence of a certain electronic data, such as proving the ownership of the original copyright of a certain electronic version of music, the ownership of the original copyright of a certain electronic version of a monograph, etc., people need to choose a credib...

Problems solved by technology

[0005] The "single center" online service method of the existing solution is easy to cause: if the network of the single center fails, the application cannot be served; the capacity of the single center network is limited, and many applications cannot be quickly confirmed

[0006] The "single-center" scheme is difficult to prevent the risk of its (or its staff) "doing evil". Chat records, other institutions and individuals in a subordinate position cannot find out, let alone provide strong evidence

[0007] This kind of system is opaque, and it is difficult for the government's regulatory responsibility to play its due role in it.

Even if there are regulations that require off-site backup of the "trusted timestamp", its credibility will inevitably be questioned because it originates from a unique institution

Also because it is opaque, the organization's CA (Certification Authority) certificate may expire or be revoked, and it is difficult for users and regulators to find out
