Problems solved by technology

From the attacker's point of view, the individuals in each equivalence class cannot be distinguished from each other, so it is impossible to determine the sensitive attribute value of the individual

Embodiment Construction

[0035] Below in conjunction with accompanying drawing and embodiment describe in detail:

[0036] 1. System

[0037] 1. Overall

[0038] like figure 1 , the privacy information anonymous publishing system 10 includes a private information database 11, a fuzzification processor 12 and an information publisher 13;

[0039] Its connection relationship is:

[0040] The privacy information database 11, the obfuscation processor 12 and the information publisher 13 are connected in sequence.

[0041] The privacy information database 11 stores the individual privacy information in the form of a table; the fuzzification processor 12 obtains the individual privacy information form from the privacy information database 11, adopts the optimal fuzzification method to fuzzify the privacy information form, and blurs the The transformed form is sent to the information publisher 13; the information publisher 13 releases the blurred form to the outside.

[0042] 2. Function block (structur...

Abstract

The invention discloses a fuzzy method for individual information in an anonymous publishing system of private information, and relates to the anonymous publishing system of private information on the Internet. This system is: the privacy information database, the fuzzy processor and the information publisher are connected in sequence; the private information database stores the individual's private information in the form of a table; the fuzzy processor obtains the individual's private information form from the private information database, and uses The optimal fuzzification method fuzzifies the private information form, and transmits the fuzzy form to the information publisher; the information publisher releases the fuzzy form to the outside. Compared with the existing technology, the method is simple and significantly improves the fuzzing efficiency of the fuzzing processor; it is suitable for publishing data with personal private information in a private information anonymous publishing system.

Description

technical field [0001] The invention relates to an anonymous publishing system for private information on the Internet, in particular to a method for fuzzifying individual information in the anonymous publishing system for private information. Background technique [0002] In order to meet actual needs, data holders often need to release certain data information to the outside world. Under normal circumstances, these data will be legitimately used by certain organizations or institutions. In special cases, due to the openness of data release, the data can also be obtained by attackers, which may lead to information leakage. Taking these two factors into consideration, the published data should guarantee both accuracy and security. The basic way to balance these two aspects is to apply some degree of anonymity to the data. A simple anonymity method is to remove the identifying attribute of each individual. However, subsequent studies have shown that only removing the iden...
