The embodiment of the invention discloses a verification method and device based on a block chain network. A verification server receives the verification request, constructs a first Merkel identity tree at least according to at least two first blind keys in the verification request, and whether the at least two pieces of identity information belong to the user is determined according to the rootof the Merkel identity tree of the user and the root of the first Merkel identity tree in the block chain network, and the Merkel identity tree of the user is constructed through the first blind key corresponding to each piece of identity information of the user. The root of the Merkel identity tree of the user in the blockchain network is combined, and the first blind key corresponding to the atleast two pieces of identity information is used for verifying the at least two pieces of identity information, so that the identity information of the user can be prevented from being provided for the verification server, and the security of the identity information of the user is improved.
Description
technical field [0001] The present invention relates to the technical field of financial technology (Fintech), in particular to a verification method and device based on a block chain network. Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field. The traditional financial industry is gradually transforming into financial technology (Fintech), and blockchain technology is no exception. However, due to the security and real-time requirements of the financial industry , Financial technology has also put forward higher requirements for blockchain technology. [0003] At this stage, different application servers usually require users to use the same identity information to log in to each application, such as the user's ID card number, mobile phone number, etc. Identity information in the application server to determine whether it is the same user. However, since the same user uses the same ident...
