5. The data processing method according to claim 1 , wherein in the first raw data of the first provider providing the first user data and the second raw data of the second provider providing the second user data, in case that identification information used for data alignment processing is of a target type, the first user data and the second user data are obtained by:

on a side of the first provider providing the first user data, performing offline encryption hash processing on the identification information of the first raw data based on a first cryptographic key to obtain the first user data; and

on a side of the second provider providing the second user data, performing noise addition processing on the identification information of the second raw data based on a second cryptographic key and noise information to obtain noise-added data, and sending the noise-added data to the first provider, and after receiving encrypted data obtained by performing encryption processing on the noise-added data based on the first cryptographic key from the first provider, performing denoising processing on the encrypted data based on the noise information, and performing a hash processing on the denoised data to obtain the second user data, wherein the first cryptographic key correspond to a private key and the second cryptographic key correspond to a public key used in asymmetric encryption.

6. The data processing method according to claim 1 , wherein the first time window and the second time window are initialized to a same length.

7. The data processing method according to claim 1 , wherein data alignment is performed based on identification information in the first data and the second data.
