Abstract

The embodiment of the invention provides a method and a device for outsourced data query verification, electronic equipment and a readable storage medium, which can solve a problem of query verification under outsourced Key-Value storage and can solve a problem of being difficult to construct a query verification object under a condition of protecting data privacy. The method comprises the following steps: sending a key query request to a key server according to a query range, acquiring a key query result returned back by the key server, wherein the key query result comprises a verification object, a key data record set and a random number set corresponding to the key data record set; sending a value query request to a value server according to the random number set, acquiring a value query result returned back by the value server, wherein the value query result comprises a value data record set and a digital signature of each value data record in the value data record set; and according to the verification object and the digital signature of each value data record in the value data record set, verifying the key data record set and the value data record set.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method, device, electronic equipment and readable medium for outsourced data query verification. Background technique [0002] In recent years, the Internet has exploded. While enjoying the fun and convenience that the Internet brings to life, people also generate massive amounts of data. Data outsourcing can not only free data owners from heavy data management tasks, so that they can pay more attention to the value of the data itself, but also the professional and efficient management mechanism of third-party service providers can greatly reduce the management cost of unit data. With the rapid development of cloud computing and cloud storage, data outsourcing will become the main service mode of data storage management in the future. [0003] However, because third-party service providers and data owners are at different market levels, and there are intertwined market inte...
