A Gini Coefficient Measurement Method of Income Distribution Gap Based on Privacy Protection

Abstract

The invention discloses a privacy protection-based income distribution gap Gini coefficient measurement method, which adopts a privacy protection-based income distribution gap Gini coefficient measurement system; the system includes a cloud server CS, a user terminal CR, a trusted third-party institution TI, and a scientific research institution SRI; first, system initialization, generate public key and private key data, encrypt private data, and send the encrypted private data to the cloud server, the cloud server aggregates and averages the encrypted data, and uses economic principles to calculate the Gini coefficient For ciphertext data, the cloud server sends the calculated ciphertext data to the scientific research institution, the scientific research institution decrypts the ciphertext data, calculates the Gini coefficient according to the decrypted data and the definition of the Gini coefficient, and finally the scientific research institution obtains the income data gap of n individuals Gini coefficient. The invention enables other individuals and institutions to complete the measurement of the Gini coefficient of the distribution gap of personal income under the condition of ensuring the privacy of personal income.

Description

technical field [0001] The invention belongs to the technical field of information security, relates to a privacy-preserving personal income gap and a privacy protection method in a Gini coefficient measurement scheme of personal income distribution gap, and particularly relates to the characteristics and personal income data in the field of research on the measurement of personal income distribution gap in economics The need for privacy protection and the need to detect the Gini coefficient of the income distribution gap of enterprise employees, through the combination of homomorphic encryption algorithm and economic technology, a privacy-protected Gini coefficient measurement method for the personal income gap of enterprise employees. Background technique [0002] The disparity in personal income distribution in the field of economics research affects the growth of the economy and the stability of the country. Maintaining a moderate and reasonable income distribution gap w...

Problems solved by technology

Maintaining a moderate and reasonable income distribution gap within and among enterprises can have a positive stimulating effect on economic growth and at the same time promote resource allocation, thereby stimulating and accelerating rapid economic growth and forming a material for improving income distribution. However, an excessive income distribution gap will also have a negative impact on the social economy, damage economic stability and efficiency growth, thereby undermining the stability and unity of the country, and eventually lead to social unrest
