A method, system, and computer program product for automatically generating service definitions for application clients of a message broker is provided. The method includes retrieving a trace of interactions between different application instances and corresponding message queues in a message brokering system. Thereafter, messages in the trace can be analyzed to identify the application instances and related message exchange data. Finally, a service definition document can be generated for each identified application instance using the related message exchange data to describe computational services provided by the identified application instance.

Automated generation of service definitions for message queue application clients

In an approach for providing navigational assistance to a target location in a vehicle parking facility, a processor accesses stored vehicle registration numbers each mapped to a location of a vehicle in a parking facility in a database. A processor associates a user with a target vehicle registration number. A processor receives input of a reference vehicle registration number from a mobile user device at a current location of the user using an input component of the mobile user device and references the database of vehicle registration numbers. A processor identifies a current location in the parking facility by look up of the reference registration number; identifies a user's target location in the parking facility by look up of the target registration number associated with the user; and generates dynamic navigational instructions from the current location to the user's target location for sending to the mobile user device.

Providing navigational assistance to target location in vehicle parking facility

A method is disclosed including receiving a request for changing a privilege of a peer of the public blockchain network, in response to receiving the request for changing the privilege, automatically submitting a trust query to a trust verification entity, receiving from the trust verification entity, a trust score associated with the peer, comparing the received trust score to a pre-determined threshold, determining, based on the comparison, that the trust score is greater than the pre-determined threshold, in response to determining that the trust score is greater than the pre-determined threshold, automatically voting that the request be granted, receiving votes of other privileged peers of the public blockchain network, determining that a number of the votes for granting the request is sufficient to grant the request, and in response to determining that the number of votes is sufficient, automatically executing the requested changing of the privilege of the peer.

Building trusted public blockchain networks based on participants' digital social behavior

Management of parking spaces in a parking area comprising a plurality of zones. A ticket is provided to an individual associated with a vehicle parked in the parking area, and the ticket is associated with the vehicle. Also, a first zone in which the vehicle is parked is identified. Responsive to the individual validating the ticket, it is determined that the vehicle associated with the ticket will be leaving the identified first zone, and there is provided an indication that a parking space of the identified first zone is to become available.

Management of parking spaces

Techniques are disclosed for performing a computer-implemented processing of slide presentation videos to automatically generate index locations corresponding to particular slides within a slide presentation video. In embodiments, a slide presentation video is uploaded to a video processing system. The video processing system performs an image analysis to identify each slide within the slide presentation and determine a time window for each occurrence of each slide. An audio analysis is performed to adjust the time window to the start of a sentence that precedes the introduction of the slide. A user interface includes one or more selectable links associated with each slide that link to a corresponding location within the slide presentation video. Similarly, a processed slide presentation video includes selectable links to index to the corresponding slide of the presentation.

Correlation of recorded video presentations and associated slides

Disclosed embodiments provide techniques for managing luggage within a premises such as an airport. A group identifier is established that includes multiple travelers. Each traveler in the group has one or more pieces of luggage that are being checked at a destination airport for a flight. When the travelers arrive, the luggage is reclaimed at the baggage claim area of the arrival airport. The group identifier is associated with each piece of luggage belonging to the group. Thus, any member of the group can properly remove luggage belonging to the group from the baggage area, thereby simplifying the airport exit procedure.

Luggage management system

For communication pattern recognition, an apparatus is disclosed. The apparatus includes a baseline analysis module that samples predefined sources associated with a user and generates a baseline fingerprint for the user. The apparatus includes an active analysis module that re-samples the predefined sources associated with the user after a predefined time interval and generates an active fingerprint for the user. The apparatus includes a verification module that compares the active fingerprint to the baseline fingerprint and determines whether the active fingerprint closely matches the baseline fingerprint. If the active fingerprint closely matches the baseline fingerprint, then the verification module replaces the baseline fingerprint with the active fingerprint. If the active fingerprint does not match the baseline fingerprint, then the verification module performs a predefined action to rectify differences between the baseline fingerprint and the active fingerprint.

Communication pattern recognition

Control of message delivery from publisher devices to a subscriber application of a messaging system is provided. The subscriber application has a subscription registered with a broker application of the messaging system and is only permitted to receive messages relating to a topic of the subscription from a predetermined set of one or more publisher devices. The method includes: altering a topic identifier of a message from a publisher device to a modified topic identifier, and altering a subscription identifier from a subscriber application to a modified subscription identifier; analyzing the modified topic identifier and the modified subscription identifier to determine if the message is to be communicated to the subscriber application, and if so, information is removed from the modified topic identifier to form a reverted topic identifier, and the message and reverted topic identifier are communicated to the subscriber application.

Message delivery in a message system

A message server includes a query store for storing query requests, value data for the query requests, and response time data for the query requests. A message is received, a query request is determined from the message and sent to a query server. A timeout period is determined from response time data stored in the query store. If no response to the query request is received within the timeout period, a value is determined from the value data for the query request stored in the query store. Alternatively, if a response to the query request is received within the timeout period, a value is determined from the response, value data for the value is stored in the query store, and response time data is stored in the query store. An action in response to the message is determined and the action is performed.

Processing a message received by a message server

Method and system are provided for updating data at a shared resource in a concurrent user environment. The method includes: a first client application carrying out the steps of: pulling data from a shared resource for update wherein the data includes a timestamp of a last update; requesting a lock on the data only allowing updates from the first client for a set period of time; working on the data whether or not a lock is in place for the first client application. Wherein when a first client application applies to update the data, a check is carried out to compare the timestamp of the data updated by the first client application with the current timestamp of the data, and if these do not match, the update fails.
