Abstract

The invention discloses a generalized linear regression method under privacy protection, aiming to solve the problem of low efficiency and low precision of generalized linear regression under encryption when the cloud is untrustworthy when computing outsourcing in the prior art. In combination with encryption algorithm, linear regression method and gradient descent method, the generalized linear regression after data set encryption is realized, that is to say, when the cloud is untrustworthy, data processing can still be performed under encryption protection, etc., realizing real computing outsourcing , realizing the mutual correspondence between the calculation of plaintext and the calculation of ciphertext, and overcoming the technical problems of low accuracy and slow calculation speed of the traditional gradient descent method under ciphertext iteration; this application is applicable to the related fields of vector homomorphic calculation.

Description

technical field [0001] The invention relates to the related field of vector homomorphic calculation, in particular to a generalized linear regression method under privacy protection. Background technique [0002] Today, with the explosive growth of data, using machine learning and data mining technology to maximize the output value of data has become the actual demand of people. However, due to the extremely limited computing resources, international IT giants such as Google, Microsoft, and IBM are developing their own cloud computing platforms for commercial use. However, cloud security has always been a bottleneck in the development of cloud computing. Eight Internet giants in the United States jointly opposed the U.S. government surveillance project, which once again brought the security issues of cloud computing to people's attention. However, it is far from enough to protect cloud security only from the policy point of view, and it cannot dispel people's concerns abou...
