Abstract: A method and an apparatus for identifying sensitive information identifier in a privacy-protection manner are provided. The method is performed at a first computing entity which is configured to access a set of license plate numbers and to communicate with a second computing entity which is configured to obtain a license plate number that is captured by one of one or more license plate recognition (LPR) devices distributed in a certain geographic area. The method comprises: receiving a first hash value of the license plate number from the second computing entity; determining that the first hash value matches a second hash value of a plurality of hash values in an association relationship; and generating a notification of an identified license plate number. The association relationship maps a respective one of the plurality of hash values to a corresponding license plate number in the set of license plate numbers.

Abstract: A method of requesting access through a door by a mobile computing device may involve: receiving a Uniform Resource Locator (URL); directing a web browser application of the mobile computing device to a webpage based on the received URL; receiving an access code from an access-control system, the access code associated with access rights of a user of the mobile computing device; and transmitting an access request to the access-control system, the access request comprising data representing at least an identifier of the door and the access code.

Abstract: A method of requesting access through a door may involve: causing a mobile computing device to receive an identifier of the door; and causing the mobile computing device to transmit an access request to an access-control system, the access request comprising data representing at least the identifier of the door and an access code. A method of controlling access through a door may involve: receiving an access request from a mobile computing device, the access request comprising data representing at least an identifier of the door and an access code; and in response to the request, allowing access through the door. Systems are also disclosed.

Abstract: A video management server is connectable to a communication network and includes a processor, an interface and a memory operatively coupled to the processor and comprising computer-readable instructions executable by the processor.

Abstract: A method for closely protecting materials (10) sensitive to contamination by airborne contaminating agents and placed on a work surface (P). At least one decontaminated gas stream (1, 2) is fed from either side towards the materials in a direction substantially parallel to the work surface, and each gas stream (3) leaves the work surface in an intermediate area between the edges of the work surface and in a direction substantially perpendicular thereto. Alternatively, at least one gas stream is fed towards the materials from above the work surface at an intermediate area between the edges thereof, and in a direction substantially perpendicular thereto, and each gas stream leaves the work surface in a direction substantially parallel thereto and on either side of the materials.
