Embodiment Construction

[0039] In order to facilitate the understanding and implementation of the present invention by those skilled in the art, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, but not to limit it. this invention.

[0040] Differential privacy is a privacy protection technology based on data distortion. It blurs the data by adding noise, while keeping the data attributes unchanged, ensuring the statistical characteristics of the data after adding noise. Differential privacy defines a strict attack model. , even if the attacker has mastered all records except one piece of information, it is still impossible to infer the privacy properties of that piece of information.

Abstract

The invention discloses a differential privacy histogram publishing method, system and device based on binary fission. The method comprises the steps of privacy budget division, middle histogram generation, histogram sorting, histogram division through binary fission, grouping and averaging, differential privacy histogram generation, histogram publishing and the like. Aiming at the problem that an existing histogram publishing technology is not high in availability, the accuracy of a grouping division stage is improved, then the availability of published data is improved, the publishing efficiency is improved, and data publishing errors can be reduced while it can be guaranteed that privacy removal is conducted on the data; and the whole histogram publishing process is safer and more efficient.

Description

technical field [0001] The invention belongs to the technical field of histogram data privacy protection, relates to a histogram data release privacy protection method, system and device, in particular to a differential privacy histogram release method, system and device based on binary splitting. Background technique [0002] With the continuous development of society, enterprises will generate a large amount of user data all the time, and these user data often have huge potential. In order to make better use of this data, discover its value. Often companies collect this data and release it to third-party agencies for research. At the same time, the direct release of these data to the outside world also brings some security risks. For example, attackers can easily obtain the user's privacy by launching a maximum background knowledge attack on the histogram data released therein, thereby causing harm to users. actual loss. Therefore, the privacy protection of data is immi...
