  • Publication number: 20200274718
    Abstract: A device and a method for authenticating an application in an execution environment in a trust zone are provided. The method includes executing a client application (CA) in a normal world, receiving, in the normal world, a request for receiving a service of a trusted application (TA) of a secure world from the CA, acquiring, when the request is received in the normal world, source information of the CA loaded in a memory of the device, acquiring, in the normal world, first hash information from the source information, providing, to the secure world, the first hash information together with signature information and a sub certificate included in the CA, and authenticating the CA based on the sub certificate and a root certificate of the TA in the secure world.

  • Patent number: 10643026
    Abstract: Disclosed is a method for identifying an action performed by a user in a third party system. Information associated with a form is received by an online system. For instance, hashed values of a plurality of form fields provided by a user and a description of the plurality of form fields are received by an online system. A form is identified based on the received information. Additionally, a determination whether one or more of the received hashed values correspond to stored values by the online system is made. If the received hashed values correspond to stored values in the online system, a user of the online system is identified based on the stored values corresponding to the one or more received hashed values. An identification of an action associated with the identified form and performed by the user in the third party system is stored.

  • Patent number: 10581991
    Abstract: An online system receives tracking requests from client devices interacting with a website. The online system analyzes user interactions with websites using the tracking requests. The online system predicts an accurate label for the web page that caused the tracking request to be generated. The online system uses the accurate label for generating reports describing user interactions with the website. The online system predicts the label of a web page received by the client device based on metadata extracted from markup language documents by the client device and provided to the online system via tracking requests. Examples of metadata extracted from markup language documents include labels and description of widgets in the web page that triggered the tracking request from the client device. The online system generates reports describing the quality of the tracking requests.

  • Patent number: 5665277
    Abstract: Method and apparatus for making nanoparticles of a material having a diameter of 100 nanometers or less wherein the material to be formed into nanoparticles is evaporated to form a vapor plume therein, a non-reactive entrainment gaseous atmosphere suitable for evaporation conditions is introduced to a first chamber, a gaseous jet is directed through the vapor plume in a direction to carry nanoparticles formed by quenching of the vapor plume through a flow restriction orifice between the first chamber and a second chamber downstream of the first chamber, recirculation of the gaseous jet and nanoparticles entrained therein from the second chamber to the first chamber is substantially prevented to thereby provide a second stage of the gaseous jet downstream of the orifice and substantially isolated from said first chamber for flow to the second chamber, and collecting the nanoparticles from the second stage of said gaseous jet in a collection chamber downstream from the orifice.
