Abstract: The invention relates to a multi-platform data sharing method and device and a computer readable storage medium. The multi-platform data sharing method comprises the following steps: unifying the length of key fields of shared data, wherein the shared data is the data that is expected to be shared among multiple platforms; encrypting the key fields of the shared data provided by each platform in the multiple platforms to obtain encrypted data, and transmitting the encrypted data to a data sharing pool; re-encrypting the encrypted data provided by other platforms in the multiple platforms in the data sharing pool separately to obtain re-encrypted data; and sending the re-encrypted data to the data sharing pool, so that the data sharing pool connects the shared data with the same encrypted field, thereby realizing data sharing among multiple platforms. According to the invention, exchangeable encryption is performed on the key fields of the shared data, so that each platform can obtain more comprehensive data information; therefore, the utilization and integrity of the shared data is improved, and the effect that the key field information of the shared data is not disclosed is ensured.
