Embodiment Construction
[0049] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0050] The invention provides a data calling method. Reference figure 1 As shown, it is a schematic flowchart of a data calling method provided by an embodiment of the present invention. The method can be executed by a device, and the device can be implemented by software and / or hardware.
[0051] In this embodiment, the data calling method includes:
[0052] S1. Receive a data set input by a user, and store the data set in a node of the data calling system.
[0053] Preferably, the data calling system may be based on blockchain technology or other distributed storage system technologies, etc. The data calling system is a new type of data management based on computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. system. For example, in a fi...

The invention relates to a basic operation and maintenance technology. The invention discloses a data calling method. The method comprises the steps of receiving a data set input by a user, storing the data into a node of a data calling system; receiving a calling request of the data set, calculating commitment values of the nodes; dividing the data into a plurality of sub-data sets, calculating asubset commitment value based on the sub-data set, solving based on the subset commitment values to obtain a total commitment value; if the total commitment value is different from the commitment value, determining that the commitment value is not the same; and if the total commitment value is greater than the commitment value, refusing the call request, if the total commitment value is the sameas the commitment value, calculating a commitment-evidence value pair corresponding to the sub-data set, judging whether the commitment-evidence value pair meets a preset condition based on a range proving method, and if the commitment-evidence value pair meets the preset condition, responding to the call request and finishing data call. The invention further provides a data calling device and a computer readable storage medium. According to the invention, an efficient data calling function can be realized.
Description
Technical field [0001] The present invention relates to the technical field of basic operation and maintenance, and in particular to a method, device and computer-readable storage medium for data calling. Background technique [0002] Data recall is to take out and use the corresponding data stored in the preset location in advance. For sensitive data, such as user identity information, it is also necessary to verify the security of the requester of the data call or decrypt the encrypted sensitive data taken out. However, with the continuous increase of data call requests, the existing processing methods greatly reduce the efficiency of data call. Therefore, how to achieve efficient retrieval of data is an urgent problem at this stage. Summary of the invention [0003] The present invention provides a data calling method, device and computer-readable storage medium, the main purpose of which is to call data according to a user's calling request. [0004] In order to achieve the a...
