20150101020 | METHOD AND APPARATUS FOR CREATING CONDITIONAL WINDOWS PROCESS TOKENS - A system and method for taking control of process token creation in the Windows operating system to create conditional process tokens that define access to system resources for process running on a Windows computer. The system includes an LSA shim layer that intercepts standard Windows requests for authentication and authorization and an authentication agent that determines context for each request. A custom authentication and authorization (A&A) store determines authentication success and the amount of authorization based on context and supplied credentials. Once the custom A&A store determines a successful log-on and defines authorization for the user, it passes the elements of authorization through the authentication agent to the LSA shim layer, which passes them on to the LSA module, which in turn uses them to request a Windows process token from the Windows kernel. The Windows kernel assigns the token to a user's session on the computer, defining the level of resource access available to processes the user launches. | 04-09-2015 |
20150106906 | METHOD AND APPARATUS FOR TRANSMITTING ADDITIONAL AUTHORIZATION DATA VIA GSSAPI - A system and method for using a GSSAPI security token to transport additional non-GSSAPI data that includes authorization data used by third-party software.

When a client process requests a security context from the GSSAPI, the hook intercepts the security token the GSSAPI provides for the client process. The hook checks to see if there is additional authorization data to transport, adds the additional data to the security token, then gives the token to the client process. The client process sends the security token to the server process, which submits the token to the GSSAPI for evaluation. A hook on this computer intercepts the security token, removes additional data added earlier, gives the added authorization data to a version of the third-party authorization software, then passes the now-unaltered security token to the server process which uses the security token to finish establishing a security context with the client process. | 04-16-2015 |
20150106917 | METHOD AND APPARATUS FOR CREATING SWITCHABLE DESKTOPS WITH SEPARATE AUTHORIZATIONS - A system and method for creating switchable desktops each with its own authorization. The system provides a custom authentication and authorization data store that defines permission sets called roles, and lists which roles each user may assume. The system also provides a custom virtual desktop manager that creates new virtual desktops using the permissions defined by roles allowed for each user. When a user requests a new virtual desktop and role from the desktop manager, the manager requests new virtual desktop components from the operating system. The desktop manager intercepts a request by the operating system to the Local Security Authority module for permissions to grant the new virtual desktop. The manager substitutes the user's requested role permissions (if the user may assume the rule) for the permissions granted by the LSA module. The LSA module and operating system grant those role permissions to the user's activities in a newly created virtual desktop. | 04-16-2015 |

20100146162 | Apparatus and Method to Maximize Buffer Utilization in an I/O Controller - An apparatus and method for maximizing buffer utilization in an I/O controller using credit management logic contained within the I/O controller. The credit management logic keeps track of the number of memory credits available in the I/O controller and communicates to a chipset connected to the I/O controller the amount of available memory credits. The chipset may then send an amount of data to the I/O controller equivalent to or less than the communicated available amount of memory credits to reduce the occurrence of a “retry” event. The amount of available memory credits is determined by comparing the available memory in each buffer within the I/O controller and designating that the “available” amount of memory for the I/O controller is an amount equivalent to the amount of memory contained in the buffer with the least amount of available memory. This “available” amount of I/O controller memory may then be converted into memory credits and communicated to the chipset. | 06-10-2010 |

20080281783 | SYSTEM AND METHOD FOR PRESENTING MEDIA - One embodiment of the present invention may permit retrieving and presenting media resources and/or providing online chat functionality. The embodiment may include a communication toolbar. The communication toolbar may be an interactive user tool that allows a user to retrieve and display document and media files, website/pages links, and/or conference links. The communication toolbar may also aid users in facilitating an on-line chat between one another. Another embodiment of the present invention takes the form of a media retrieval and display module that may show any and all retrieved search results to the user. Each search result may include a text description of the media record file, such as a title, a link to the media record file and a time bar associated with the media record file. The time bar may include at last one graphic indicator corresponding to a time in the media file where the search term is used. | 11-13-2008 |
