Simple, secure login with multiple authentication providers
A secure distributed single-login authentication system comprises a client and a server. The client collects a user name and password from a user and tests that user name and password at a variety of potential authentication servers to check where the login is valid. It combines the password with a time varying salt and a service specific seed in a message digesting hash and generates a first hash value. The client sends the hash value along with the user name and the time varying salt to a currently selected server. The server extracts the user name and looks up an entry under the user name from the selected server's database. If an entry is found, it retrieves the password and performs the same hash function on the combination of the user name, the service specific seed, and the retrieved password to generate a second hash value. Then, it compares two hash values. If these two values match, the user is authenticated. In this way, the system never sufficiently reveals the password to authentication agents that might abuse the information. |

System and method for improving the navigation of complex visualizations for the visually impaired
The present invention relates to a system and method for improving the navigation of complex visualizations on a computer display for the visually impaired persons to toggle between objects or nodes. An object or node may be a square, a circle or other object which a display screen may show. The objects or nodes have characteristics which may include a name which indicates the name of the node, a direction which indicates the direction of the next node to progress to (along an arc), priority which indicates the priority that the node has with respect to other nodes, properties which indicates the certain properties of the node, and operation which indicates the operation to be performed. The system has a user indicator for indicating to the visually impaired user the characteristics of the objects or nodes which are connected by arcs. The node or object characteristics are informed to the user by the indicator to allow the user to toggle from one node to the other along the arc route. The system has a control center which has a receiver for receiving the toggle commands and node characteristics from each node. The toggle command moves a selector (which selects which object is being acted upon—sometimes, for visually unimpaired people, the selected object is shown in bold or a distinct color) to the next node according to the characteristics. The receiver also passes the node characteristics to a parser. The parser parses the node characteristics and passes it on to the director for determining the next step. The director examines the characteristics, such as name, direction, properties, and operations, and indicates to the user the characteristics of the node—generally by audible means but not so limited. This allows the visually impaired user to ascertain where he/she on the display. This is generally done by way of an audible device but could be accomplished in other ways. |

Managing web tier session state objects in a content delivery network (CDN)
Business applications running on a content delivery network (CDN) having a distributed application framework can create, access and modify state for each client. Over time, a single client may desire to access a given application on different CDN edge servers within the same region and even across different regions. Each time, the application may need to access the latest “state” of the client even if the state was last modified by an application on a different server. A difficulty arises when a process or a machine that last modified the state dies or is temporarily or permanently unavailable. The present invention provides techniques for migrating session state data across CDN servers in a manner transparent to the user. A distributed application thus can access a latest “state” of a client even if the state was last modified by an application instance executing on a different CDN server, including a nearby (in-region) or a remote (out-of-region) server. |

Sub-threshold stimulation to precondition neurons for supra-threshold stimulation
In order to generate the smallest phosphenes possible, it is advantageous to selectively stimulate smaller cells. By hyperpolarizing the somas of the large cells selectively with sub-threshold anodic ‘pre-pulse’ stimuli (making them more difficult to stimulate) and then selectively depolarize the smaller cells one can selectively stimulate smaller cells. Alternatively, one can hyperpolarize the dendrites of the cells with larger dendritic fields by applying sub-threshold anodic currents on surrounding electrodes and then depolarizing the smaller cells in the center. Further, one can manipulate the phases of an individual biphasic wave to affect selective stimulation resulting in more focal responses. It is possible to increase resolution with the ‘pre-pulse’ described above. One can also effect resolution by modifying the pulse order of the cathodic and anodic phases. Further, one can isolate the effect of the phases by separating them in time (long inter-phase interval) or by making one of the phases long and low amplitude—always keeping equal total charge for the two phases. As an example, one can preferentially stimulate smaller ganglion cells by providing a longer sub-threshold anodic pulse balanced with a shorter supra-threshold cathodic pulse. Preferentially stimulating the smaller ganglion cells will allow stimulation of different brightness levels while maintaining high spatial resolution. |

Signaling gateway for multihop-relaying a signaling message
If interaction between signaling gateways frequently occurs, it is possible that extended processings are executed redundantly on a path of signaling messages. To avoid such a redundancy, a consistent method is necessary for deciding a signaling gateway to execute an extended processing from among the signaling gateways. The signaling gateways, each time they receive a signaling message, calculate information about a path through which it is transferred. By passing the path information in addition to the signaling message to an extended processing program, the signaling gateways decide whether to execute the extended processing on the signaling gateways, on a session basis. A signaling gateway that has executed an extended processing adds information indicating a processing status to the signaling message to notify other signaling gateways of it. |

Method and apparatus for automatic inter-domain routing of calls
A method and apparatus for inter-domain routing of calls in a network, where the network represents a first wide area network. A routing node of the network advertises its access to a range of addresses in a second wide area network and a cost for access to the range of addresses to all adjacent nodes in the network. Each of the adjacent nodes inserts an entry in its own routing table associating access to the range of addresses in the second wide area network with the network address of the routing node and the cost for access. Each adjacent node then modifies the cost for access by adding its own cost and advertises its access to the range of addresses in the second wide area network and the modified cost for access to all of its adjacent nodes. When a call addressed to a destination address in the range of address in the second wide area network is received at each node of the network, then the node searches for the entry in its routing table corresponding to the range of addresses in the second wide area network having the lowest cost for access and connects the call to the adjacent node associated with the entry having the lowest cost. The routing node can also advertise one or more protocol types which it can support, where the protocol types are associated with the routing node in the routing table in each adjacent node and a call having a given protocol type is also routed at each node of the network based upon its protocol type. |
