20090077391 | Method and apparatus for protecting data during storage/retrieval - For protecting data during transmission between a host device and a data storage device, the host device encrypts command-related information and sends the encrypted command-related information to the data storage device. The data storage device decrypts the encrypted command-related information, interprets the decrypted command-related information to generate interpreted commands, and executes the interpreted commands. | 03-19-2009 |
20140205093 | METHOD AND SYSTEM FOR GENERATING A RANDOM NUMBER - For generating a seed, such as for a random number, a plurality of data storage location identifiers, such as sectors, can be combined. A random number can be calculated using the seed. The selection of the data storage location identifiers can be time varied based on commands received from a host. The seed that is generated can have enhanced unpredictability and complexity for secure data cryptography. | 07-24-2014 |

20090173679 | BIOLOGICAL REMOVAL METHOD OF PHOSPHORUS AND NITROGEN USING GRANULATED METHAN-OXIDIZING BACTERIA AND APPARATUS THEREFOR - A biological removal method of phosphorus and nitrogen includes supplying a mixture gas into a gas holder. Inflow water and return water are supplied into the gas holder to make the mixture gas dissolved in the inflow water and the return water. The return water was provided from a granulation biological reaction tank. The inflow water and the return water including the dissolved mixture gas are transported to the granulation biological reaction tank. A nitrogen-based component is removed from the inflow water and the return water using methan-oxidizing bacteria granulated in the granulation biological reaction tank. Treated water without the nitrogen-based component is transported to an anoxic tank for treatment, and discharged from the anoxic tank. | 07-09-2009 |
