A method is provided for encrypting data to be stored in a data storage medium. The method includes encrypting the data using a special key associated with the electronic device. One example of the special key is a barcode of the electronic device. The encrypted data then is stored in the data storage medium. When the data stored in the data storage medium is decrypted, only the electronic device has the special key i.e., the barcode, can reproduce the encrypted data. When the data storage medium is lost or stolen, the encrypted data cannot be decrypted by another electronic device because the barcode of current electronic device is different from the original electronic device. Therefore, the encrypted data stored in the data storage medium is prevented from being read out by other electronic devices.
