The invention relates to a computerized method for processing a graph containing a set of nodes processing a graph containing a set of nodes, wherein forest of trees is provided corresponding to a directed acyclic graph containing a set of nodes, each of said nodes having a type chosen from a set of types; a depth for each node in said forest of trees is determined; in a breadth-first traversal manner, the depth and type of each node in said forest of trees is compared to a predefined matrix, said matrix defining for each depth and type combination one of the following actions to be carried out: no action, creating a new sub-tree, triggering exception handling.

Method for processing a graph containing a set of nodes

Various embodiments for maintaining security and confidentiality of data and operations within a fraud detection system. Each of these embodiments utilizes a secure architecture in which: (1) access to data is limited to only approved or authorized entities; (2) confidential details in received data can be readily identified and concealed; and (3) confidential details that have become non-confidential can be identified and exposed.

Confidential fraud detection system and method

For providing a service-centric approach to allocating computing service power to users in a heterogeneous distributed computing environment such as a grid, a grid service broker comprises a central service broker and distributed service brokers. Service power is measured in resource-independent service units defined and used by the service broker. The central service broker uses meta-scheduling for distributing service requests to the distributed service brokers, based on projected service units needed to process the service requests.

Providing computing service to users in a heterogeneous distributed computing environment

The present invention discloses a system and method for configuration of access rights to sensitive information handled by a sensitive Web-Service. In a case of requested configuration changes initiated by the client system the Web-Server system provides a configuration data file to the client system preferably using a SOAP-communication protocol. The changes of the configuration data file are exclusively performed offline at the client side and the updated configuration data file is signed with authentication information and sent as a part of a SOAP-request to the Web-Server system. The Web-Server system provides a filter component for identifying and discarding non-SOAP requests as well as an access control manager for providing authentication examination for incoming SOAP-requests. After successful passing these components the SOAP-request is used for updating the existing configuration data file.

System and method for secure configuration of sensitive web services

A method and apparatus provide security for a network-connected vehicle (or other networked environment) in which a predefined set of permitted operations relating to protected resources can be initiated remotely from elsewhere in the network, while security is maintained for the protected resources (for example, an engine performance optimization control unit or air conditioning control unit within a vehicle) by preventing remote initiation of any other operations on a data processing unit which is connected to the protected resources. One of a pair of gateway components runs on each of two data processing units within the vehicle (or other environment), the first processing unit being connected to the vehicle's device control units and the second processing unit being connected to the external network. The gateway components control the types of communications which can be passed from the network-connected side to the first processing unit such that only permitted operations can be requested and no unauthorized operations can be initiated remotely.

Security for network-connected vehicles and other network-connected processing environments

The present invention discloses a system and method for counting Web-Services by means of a Resource-Counter Service offered as an own, independent Web-Service based on a SOAP communication protocol as well as a system and method for billing Web-Services using the result of the Resource-Counter Service for calculation of a charge. The Resource-Counter Service may be accessed by all Service-Provider having service description of the Resource-Counter Service. The service description for the Resource-Counter Service may be preferably created and published by the Service-Provider, categorized by the Service-Broker, and can be found and used to invoke the Resource-Counter Service by all Service-Provider using a charging model for their Web-Services. The Resource-Counter Service mainly provides the functionality to create all necessary data allowing calculation of the charge for the use of a Web-Service. The final calculation of the charge itself may be done by a separate specific accounting and bill presentment component.

A processor unit for a data-processing-aided electronic control system in a motor vehicle, in which the processor unit operates in real-time and contains within its functional structure a scalable computing unit and a vehicle interface unit, as well as (preferably) a communication coprocessor as separate structural components.

An integrated circuit chip (110) adapted to provide interconnect capability and an AC interconnect test method therefor. Test and control data are scanned in the scan-path of latches (114 and 115) to initialize the AC interconnect test. Subsequently the functional system mode is simulated by applying the functional-system clocks via lines (118 and 128).

A test pattern generator includes a random pattern generator and a shift register. The random pattern generator generates a series of digits which are input to the shift register and stored therein. Each digit output by the random pattern generator has a probability of having a first value, such as representing '1'. The output probability of the random pattern generator is adjustable. The shift register has a plurality of outputs for outputting a test pattern comprising the stored digits. The shift register includes a series of latches and at least a first logic circuit connecting the output of the random pattern generator to the input of a first latch, or connecting the output of a latch to the input of a next adjacent latch. In a first state, the logic circuit has an output probability which is independent of the output probability of the random pattern generator. In a second state, the logic circuit has an output probability which is dependent on the output probability of the random pattern generator.
