授信文件的获取方法、索引服务器、查询服务器和介质Acquisition method, index server, query server and media of trusted documents

技术领域technical field

本发明涉及网络通信技术，尤其涉及一种授信文件的获取方法、索引服务器、查询服务器和介质。The invention relates to network communication technology, in particular to a method for acquiring a credit authorization file, an index server, a query server and a medium.

背景技术Background technique

随着互联网的逐步发展，行业短信在营销方面呈现出越来越普遍以及逐年递增的趋势，但同时对用户的骚扰和投诉也呈现逐年递增的趋势。With the gradual development of the Internet, industry SMS marketing is becoming more and more common and increasing year by year, but at the same time, harassment and complaints to users are also increasing year by year.

为了防止营销类短信对于用户的骚扰，包括信管局、运营商在内对于营销短信的管理，一直采取用户授信的方式，即商户如果想对用户进行营销，需要获得用户的授信。用户授信一般采用文件的方式，并将授信文件存储于区块链节点，以确保用户的授信文件不被篡改。In order to prevent marketing text messages from harassing users, the management of marketing text messages, including the Information Administration Bureau and operators, has always adopted the method of user credit, that is, if merchants want to market users, they need to obtain user credit. User credit generally adopts the form of files, and the credit files are stored in blockchain nodes to ensure that the user's credit files are not tampered with.

现有授信文件的查询只能通过用户手机号等已经预先设定好的字段进行查询。因此，在实际提取授信文件的过程中，只能查询出来用户在区块链节点上所有存储的授信文件，并需要用户对所有授信文件逐一比对后，才能确定最终的授信文件。可见，授信文件的查询效率较低。The query of the existing credit documents can only be queried through the pre-set fields such as the user's mobile phone number. Therefore, in the process of actually extracting credit documents, all the credit documents stored by the user on the blockchain node can only be queried, and the final credit document can only be determined after the user compares all the credit documents one by one. It can be seen that the query efficiency of credit approval documents is low.
