| 20100153695 | DATA HANDLING PREFERENCES AND POLICIES WITHIN SECURITY POLICY ASSERTION LANGUAGE - Whether user-side privacy preferences and service-side privacy policies are matched is determined utilizing an extended security policy assertion language. Both privacy policies, i.e. how data recipients promise to treat data, and privacy preferences, i.e. how data providers expect their data to be treated, are expressed with the same language. Decisions are made through evaluation of queries based on preference and policy assertions. | 06-17-2010 |

| 20090119672 | Delegation Metasystem for Composite Services - A delegation metasystem for composite services is described, where a composite service is a service which calls other services during its operation. In an embodiment, the composite service is defined using generic descriptions for any services (and their access control models) which may be called by the composite service during operation. At run time, these generic descriptions and potentially other factors, such as the user of the composite service, are used to select actual available services which may be called by the composite service and access rights for the selected services are delegated to the composite service. These access rights may subsequently be revoked when the composite service terminates. | 05-07-2009 |
| 20100017602 | Ad-Hoc Trust Establishment Using Visual Verification - Methods for ad-hoc trust establishment using visual verification are described. In a first embodiment, a visual representation of a shared data is generated on two or more devices and the visual representations generated can be visually compared by a user. This method can be used to verify that the correct devices are involved in a negotiation, when pre-existing trust relationships do not exist between the devices. The visual representation may, for example, comprise a picture with a number of different elements, each representing a part of the shared data. In another embodiment, a method of secure key exchange is described in which, before sharing the keys, the parties exchange information which encapsulates the key. This information can be used subsequently to check that a party has not changed the key that they are using and prevents a man in the middle attack. | 01-21-2010 |
| 20100082989 | Storing Composite Services on Untrusted Hosts - A method of storing a composite service on an untrusted host without enabling the untrusted host to access resources called by the composite service is described. In an embodiment, the delegator provides a delegatee with credentials to enable verification of the composite service and to enable access to the resources. The credential which is provided to enable access to the resources may be a credential which can be used to decrypt access credentials for each of the resources. These access credentials are stored in encrypted form in a credential store. The delegatee downloads the composite service and the encrypted access credentials and executes the composite service once it has been verified. | 04-01-2010 |

| 20110283335 | HANDLING PRIVACY PREFERENCES AND POLICIES THROUGH LOGIC LANGUAGE - A logic language model for handling of personal data by specifying users' preferences on how their personal data should be treated by data-collecting services and the services' policies on how they will treat collected data is provided. Preferences and policies are specified in terms of granted rights and required obligations, expressed as declarative assertions and queries. Query evaluation is formalized by a proof system for verifying whether a policy satisfies a preference is defined. | 11-17-2011 |

| 20120100214 | Sustained-Release Tablet and Process for Preparing the Same - A method for producing a sustained-release tablet having improved stability and content uniformity is provided. The method involves first preparing a core tablet by granulating, drying, milling, blending, and compressing a mixture of active and inactive ingredients. Four coating layers are applied to the core tablet: an inner layer, an enteric coating layer, an active layer, and an outer layer. The active ingredient may be a tetracycline, such as doxycycline. A sustained-release tablet prepared according to the method is also described. | 04-26-2012 |

| 20080282171 | System and method for production of online magazines - A computer system for supporting inclusion of continuously updated content into web publications, the computer system including an input unit for obtaining content from a plurality of sources of continuously updatable content at independent locations over a network, and a selection unit for representing the plurality of sources to a user, allowing the user to select from the plurality of sources using the selection unit, thereby building content from the selected sources into a web publication produced online by the user. Related apparatus and methods are also described. | 11-13-2008 |

| 20110170647 | Method and apparatus for controlling charged particles - An apparatus and method for controlling charged particles. The charged particles comprise electrons and positive ions. A magnetic field having only point cusps is used to confine energetic injected electrons and so to generate a negative potential well. Positive ions injected into or created within the negative potential well are trapped therein. The magnetic field is generated by current-carrying elements arranged at positions spaced from but closely adjacent and parallel to edges of a polyhedron which has an even number of faces surrounding each vertex or corner. The current-carrying elements must be spaced apart at their corners (the vertices of the polyhedron) so as not to touch, and the containing structures for the current-carrying coils of the magnetic-field-providing system are conformal to the fields so produced. | 07-14-2011 |
