Patent number: 8738779Abstract: The present invention relates to a context-based service look up, wherein a service instance, having a scope includes at least one service instance data set having a hierarchy of levels. A service consumer data set, having a hierarchy of levels is received from a service consumer, having a situation. Comparisons are made of each service consumer data set with each service instance data set, for the same level. Dependent on results of the comparisons, it is determined whether said situation of said service consumer matches said scope of said service instance.Type: GrantFiled: June 6, 2008Date of Patent: May 27, 2014Assignee: International Business Machines CorporationInventors: Carl Binding, Francois Bernard Dolivo, Reto Josef Hermann, Christian Hoertnagl, Andreas Schade

Patent number: 8271424Abstract: A method of preserving privacy and confidentiality in a system where information is associated with an existing web page having an address. The method includes receiving a store command from a first user system, the store command including at least a database key and information to be associated with the web page, wherein the database key was created by performing a cryptographic hash function on the address of the web page; storing the information at a location in a storage database; associating the location with the database key; receiving a retrieve command from a second user system, the retrieve command including the database key calculated by the second user system; retrieving stored information from one or more locations in the database associated with the database key; and transmitting the stored information to the second user system.Type: GrantFiled: May 15, 2008Date of Patent: September 18, 2012Assignee: International Business Machines CorporationInventors: Daniela Bourges-Waldegg, Christian Hoertnagl, James F. Riordan

Patent number: 8266140Abstract: A method of acquiring tags using web search includes receiving a search query in a search engine, processing the search query and returning a list of candidate resources corresponding to the search query, determining a candidate resource out of the list of candidate resources, extracting tags from the search query, and tagging the candidate resource with the extracted tags.Type: GrantFiled: March 13, 2009Date of Patent: September 11, 2012Assignee: International Business Machines CorporationInventors: Daniela Bourges-Waldegg, Christian Hörtnagl, James F. Riordan, Andreas Schade

Patent number: 8166306Abstract: A method is provided for adding intended meaning to digital signatures. A message, being base content, is received to be signed. Assertions, ontologies, and description of a reasoner are adjoined to the message. Ontologies are a formal specification of vocabulary and rules used to state the assertions. The reasoner validates the assertions against the corresponding ontologies. A compound message is formed including the message, the assertions, the ontologies, and the reasoner. The compound message is signed using a cryptographic digital signature, where the assertions indicate an intended meaning of the digital signature. During verification of semantic signatures, a digital signature is received for a compound message, where the compound message includes assertions, ontologies, and reasoner. The digital signature is verified, and the compound message structure is checked for semantic signature conformance.Type: GrantFiled: June 18, 2008Date of Patent: April 24, 2012Assignee: International Business Machines CorporationInventors: Christian Hoertnagl, James F. Riordan, Daniela Bourges-Waldegg

Publication number: 20090319530Abstract: A method is provided for referencing content by generating a bound uniform resource locator. Content is selected, a fragment identifier is calculated for the content, and the content is normalized. A content digest of the normalized content is calculated. A content binding document is assembled in which the content binding document comprises: an original URL to the content, the fragment identifier, the name of a method for normalizing the content, the name of a method for calculating the content digest, and the content digest. A content binding document digest is calculated. A bound universal resource locator is generated that contains the content binding document digest and the name of the method that was used to calculate the content binding document digest. The content binding document is stored using its digest as a file name or database key, and the content binding document can be retrieved using the bound universal resource locator.Type: ApplicationFiled: June 18, 2008Publication date: December 24, 2009Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Christian Hoertnagl, James F.

Publication number: 20060247937Abstract: The present invention relates to a context-based service look up, wherein a service instance, having a scope (O), comprises at least one service instance data set (b) having a hierarchy of levels. A service consumer data set (a), having a hierarchy of levels is received from a service consumer (1), having a situation (S). Comparisons are made of each service consumer data set with each service instance data set, for the same level. Dependent on results of the comparisons, it is determined whether said situation (S) of said service consumer (1) matches said scope (O) of said service instance.Type: ApplicationFiled: April 28, 2005Publication date: November 2, 2006Applicant: International Business Machines CorporationInventors: Carl Binding, Francois Dolivo, Reto Hermann, Christian Hoertnagl, Andreas Schade
