Distributed one-hot coding method and device, electronic equipment and computer storage medium

The invention provides a distributed one-hot coding method and device, electronic equipment and a computer storage medium, and the method comprises the steps: obtaining a local class feature set of each participant, the local class feature set being a class feature set obtained after the local data of each participant is de-duplicated; generating a global encoder according to the local category feature set; and sending the global encoder to each participant, wherein the global encoder is used for carrying out one-hot encoding on local data of each participant. The server collects a local category feature set, so that the privacy and security of data transmission among all parties can be protected. Besides, all the participants perform coding according to the global encoder, so that all the participants use the same coding mode to code local data, the situation that one-hot coding vectors after data coding of all the participants are inconsistent or conflicted can be avoided, and data unification and managemen
