20080256357 | METHODS AND APPARATUS FOR ACCESS CONTROL IN SERVICE-ORIENTED COMPUTING ENVIRONMENTS - Improved access control techniques for use in a service-oriented computing environment are disclosed. For example, one method for authenticating a client in a service-oriented environment, wherein the service-oriented environment includes a plurality of services, includes the following steps. At least one service of the plurality of services is invoked. State information is associated with the at least one service invoked. The state information is used to authenticate a client with at least one service. Further, a method for access control in a service-oriented environment, wherein the service-oriented environment includes a plurality of services, includes the following steps. A rule specification language is provided. At least one rule is specified using the rule specification language. A verification is performed to determine whether or not the client satisfies the at least one rule. The client is granted access to a service when the client satisfies the at least one rule. | 10-16-2008 |
20090100504 | Methods and Apparatus for Adaptively Determining Trust in Client-Server Environments - Techniques are disclosed for adaptively determining trust in client-server environments. By way of example, a method for assigning a trust level to a client in a client-server environment including at least one client communicating with a plurality of servers includes the following steps. Information associated with a server s | 04-16-2009 |
20090177841 | Methods and Systems for Consistently Replicating Data - Techniques for maintaining consistent replicas of data are disclosed. By way of example, a method for managing copies of objects within caches, in a system including multiple caches, includes the following steps. Consistent copies of objects are maintained within the caches. A home cache for each object is maintained, wherein the home cache maintains information identifying other caches likely containing a copy of the object. In response to a request to update an object, the home cache for the object is contacted to identify other caches which might have copies of the object. | 07-09-2009 |
20100114620 | Service Description Refinement Based on Actual Service Use - Techniques are disclosed for generation and refinement of service descriptions based on records of invocations of the services, i.e., service description refinement based on actual service use. For example, a method for describing one or more services in a service-oriented environment comprised of one or more clients invoking the one or more services comprises the following steps. An initial description is established for at least one of the one or more services. Information is collected from one or more service invocations including at least one of a client identity, a value of at least one parameter, a return value, and an execution time. The information is analyzed to refine the description. | 05-06-2010 |
