A method performed by a computing system. Embodiments of the method include shifting source data by a shift amount and encrypting the shifted data with an encryption key to produce encrypted data. An encryption package is produced by removing a portion of the encrypted data. Decryption data is generated that includes the shift amount, the encryption key, the location in the encrypted data from which the data was removed, and the data that was removed. Copies of the encryption package are sent to remote client computing devices and the system waits until a decryption time. At the decryption time, copies of the decryption data are sent to the client computing devices, which are each configured to decrypt the encryption package using the decryption data to obtain the information of the source data at substantially the same time.
