Embodiment Construction

[0026] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure, and to fully convey the scope of the present disclosure to those skilled in the art.

[0027] Secure multi-party computing is used to solve the collaborative computing problem of protecting privacy among a group of participants who do not trust each other. Multiple business platforms can act as participants, and use secure multi-party computing to realize collaborative computing of business data without disclosing their respective business data.

[0028] Generally, secure multi-party computing can be divided into tw...

Abstract

The invention discloses a data processing method, device and equipment, and a storage medium; the method is applied to a first electronic device, and the first electronic device and at least one second electronic device jointly participate in secure multi-party computing, and the method comprises the steps of obtaining to-be-processed service data; generating a first random number matrix and a second random number matrix, and generating a third random number matrix according to a preset encoding mode, the first random number matrix and the second random number matrix, the number of elements ofthe random number matrix encoded by the preset encoding mode being smaller than the number of elements of the random number matrix before encoding; and encrypting the service data in a secure multi-party computing process according to the first random number matrix, the second random number matrix and the third random number matrix. According to the invention, the generation efficiency of the matrix multiplication triad can be improved, and the encryption efficiency of service data in secure multi-party calculation is further improved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a data processing method, device, equipment and storage medium. Background technique [0002] In some business scenarios, multiple business platforms collect their own business data. For example, browser platforms collect users' web browsing data, and online shopping platforms collect users' online shopping data. These business data are very valuable and are usually kept as private information of the business platform. Each business platform does not expect to share business data in raw form with other business platforms. However, in some requirements, multiple business platforms expect to perform collaborative computing without disclosing the business data of all parties to improve business processing capabilities. For example, browser platforms and online shopping platforms expect to use web search data and online shopping data to build more accurate recommendation models. B...
