Provided are a correlation coefficient acquisition method, an electronic device, and a non-transitory computer readable storage medium. The implementation scheme is as follows: first original data is acquired, the first original data is homomorphically encrypted by using an associated key to determine first transmission data, where the associated key is jointly agreed by the first participation node and a second participation node; the first transmission data is sent to an auxiliary node so that the auxiliary node receives the first transmission data and performs a homomorphic operation on the first transmission data and second transmission data to obtain correlation coefficients between the first original data and second original data, where the second transmission data is determined by the second participation node homomorphically encrypting the second original data by using the associated key; and the correlation coefficients fed back by the auxiliary node is received.
