20090164779 | FILE SYSTEM FILTER AUTHENTICATION - A software entity on a host device attempting to access protected content in a secure memory device must be authenticated using a challenge/response authentication mechanism before the secure file system can be accessed. A file system filter determines whether requested content is protected. If the content is protected, the file system filter provides a challenge to the software entity and generates a file system filter response using the same challenge. The software entity must then send a software entity response using the challenge to the file system filter. If the file system filter determines that the software entity response matches the file system filter response, the software entity is allowed to access the protected content through a secure file system installed on the host device for the memory device. | 06-25-2009 |

20090182919 | Media Card Command Pass Through Methods - Methods for transmitting application specific or extended commands between a host and a memory card are disclosed. Commands for an extended card protocol are embedded in messages, along with a marker, in the data or command portion of a base card transmission protocol that is used to communicate between the host and the memory card. This allows for the transmission of application specific commands that lack a corresponding command in the base card protocol. The method can be implemented on the host side at the device driver level or the file level. In order to implement a read command in the extended card protocol, a write command in the base card protocol with an encapsulated read command in the extended protocol is first sent to a logical address, followed by a read command to the same logical address. Message set identifiers associate embedded commands and data received in separate transmissions. | 07-16-2009 |

The set of code is used to control access to the peripheral device from the host device. The set of code also contains one or more subsets of code that can be used by software entities on the host device for access to the peripheral device. A software entity on a host device must be successfully authenticated with the set of code installed on the host device. Once the software entity is successfully authenticated, the set of code will provide access to the one or more subsets of code specific to the software entity. The one or more subsets of code can be used by the software entity to access the peripheral device. | 11-26-2009 |

20100048169 | Memory device upgrade - Technology for replacing a first storage unit operatively coupled to a device is provided. Content of the first storage unit is sent to a new storage unit that serves as the replacement of the first storage unit. In one embodiment, the content is first sent to a trusted third-party server and then transferred from the server to the new storage unit. A portion of the content on the new storage unit is adjusted in one embodiment to maintain content security features that were implemented in the first storage unit. The upgrading can be performed under the control of a software entity that is installed on the device. In various embodiments, the first storage unit may be bound to a third storage unit prior to the upgrade process. In such cases, the process can include measures to bind the new storage unit to the third storage unit. | 02-25-2010 |
20100050241 | Accessing memory device content using a network - A first storage unit is bound to a second storage unit based on a binding type associated with content on the first storage unit, the first storage unit being operated through a first host device, and the second storage unit being operated through a second host device. When content on the first storage unit is requested in the first host device, the first host device will calculate an account identifier based on the binding type associated with the requested content and send the account identifier to a server. The server will send the account identifier to the second host device, and the second storage unit will use the account identifier to calculate a credential. The credential will be sent to the first host device through the server. The credential can be used to access the requested content if the credential is valid. | 02-25-2010 |
20100153672 | CONTROLLED DATA ACCESS TO NON-VOLATILE MEMORY - A method of controlling data access to non-volatile memory is disclosed. The method includes storing a data file in a non-volatile memory. The non-volatile memory includes a memory array including a plurality of address ranges one or more of which corresponding to a protected portion of the memory array and one or more of which corresponding to an unprotected portion of the memory array. The method also includes communicating to a host device an indication that a memory request with respect to the protected portion of the memory array is denied.

20110131421 | METHOD FOR INSTALLING AN APPLICATION ON A SIM CARD - A method of installing an application on a SIM card is disclosed. A host agent in a host device installs an application on a Subscriber Identity Module card from a non-volatile storage device. The host agent coordinates mutual authentication between the non-volatile storage device and a Subscriber Identity Module card in the host device. If the mutual authentication is successful, the host agent reads an application from the non-volatile storage device and installs the application on the Subscriber Identity Module card, wherein installing the application enables the Subscriber Identity Module card to execute the application. The application may be protected from tampering or unauthorized copying during the host agent transfer by creation of a secure communication channel or transferring encrypted applications. The Subscriber Identity Module card may verify the signature associated with an application before installation to prevent the installation of unauthorized or tampered applications. | 06-02-2011 |
