Server-side personal privacy data protecting method in network information system

Abstract

The invention discloses a server-side personal privacy data protecting method in a network information system. The server-side personal privacy data protecting method provided in the network information system is capable of supporting various types of common text query, high query performance and high safety. By paving intermediate software between a client side and a server side of the network information system to implement the provided server-side personal privacy data protecting method to realize two functions: one is storing personal privacy data inputted by the client side of the system into a background database of the server side of the system after the personal privacy data is encrypted and guaranteeing safety of personal privacy information at an incredible server side; the other is building proper indexes for the personal privacy data so as to support common text queries including accurate query, similarity query, range query and the like and guaranteeing efficiency of cryptograph query.

Description

technical field [0001] The invention relates to the technical field of network personal privacy information protection, in particular to a server-side personal privacy data protection method in a network information system. Background technique [0002] With the rapid development of network technology and information technology, network information system has been more and more widely used. However, with the continuous advancement of the informatization process, a large amount of personal privacy data has been collected in the background database of the network information system, such as ID number, personal name, personal phone number, bank account number, etc. Obviously, these data information is very sensitive and private, if it is accidentally leaked, it will inevitably pose a serious threat to the security of personal privacy data. [0003] figure 1 Shows the overall framework structure of the network information system, in which the client of the network information ...
