Abstract: A method and a system of secured data storage and recovery are provided. First, a secured key and an encrypted user password of a storage device are obtained by using a controller of a storage device. Then, the secured key is encrypted by using the encrypted user password to generate a first private key, the encrypted user password is encrypted by using the secured key to generate a second private key, and data to be stored is encrypted by using the secured key. Finally, the encrypted data, the first private key, and the second private key are transmitted to a remote device for storage through a host. Thereby, the security of data storage is enhanced and data recovery mechanism is provided when the storage device is damaged or lost.
