An embodiment sends, at a first time, from a boundary server to a client system in response to a challenge request, a challenge specifying a computational problem to be solved by the client system, the boundary server specified in a challenge list sent to the client system. An embodiment receives, at a second time, at the boundary server, a challenge response from the client system, the challenge response comprising a solution to the computational problem. An embodiment generates, at the boundary server, a certificate encoding an elapsed time between the first time and the second time, the certificate usable by the client system to prove a location of the client system. An embodiment sends, from the boundary server to the client system, the certificate.

Client-server response time based computer system geolocation

An embodiment of the invention may include a method, computer program product and system for processing a natural language query. An embodiment may include receiving text of the natural language query. An embodiment may include extracting a set of features from the text through natural language processing. An embodiment may include generating a structured query based on the set of features. An embodiment may include normalizing the text to create a normalized natural language query. An embodiment may include executing a search of a corpus via the structured query and the normalized natural language query. An embodiment may include returning results of the search.

Increasing pertinence of search results within a complex knowledge base

A lock base attached to a computer housing has a controller in circuit communication with a processor of the computer. A cable socket comprising a flash memory locks onto the lock base, two ends of an internal wire of the cable form a closed electric circuit loop with the lock base through the entirety of the body of the cable, and the controller performs a handshake with the processor of the computerized device and the flash memory that generates a checksum key stored on the flash memory, the computerized device requiring access to the checksum key on the flash memory for access to data on a memory device of the computerized device. Absent a keyed unlocking, the controller erases the checksum key from the flash memory in response to a break in the circuit loop or dislocation of the cable socket from the lock base.

Cable lock with confidential data protection

A solution is proposed for controlling usage of one or more perishable products. A corresponding method comprises storing an indication of one or more package events that may affect a duration of the perishable product being sensed by one or more sensors associated with the package; receiving an interrogation signal from a smart portable device of a user of the perishable product; retrieving package information being stored in association with the control unit in response to the interrogation signal, the package information comprising the indication of at least part of the package events; and transmitting the package information to the smart portable device for use by the smart portable device to control the usage of the perishable product according thereto.
