  • Publication number: 20180374124
    Abstract: Many mobile devices such as smart phones can generate content ranging from text and audio, to images and videos that are taken with their cameras. These devices are also equipped with wireless radios and magnetometers that can be used to obtain position and orientation information. It is possible to allow the user of the mobile phone to add the position and orientation information of the mobile and date/time to the content that the mobile generates. Thus, emails, Short Message Service (SMS) messages, blog entries, audio recordings, and pictures/video that are generated with the mobile can be geotagged with the mobile's position and orientation, as well as the date and time. This information can then be used by a location-based contextual advertising server to provide more relevant on-line ads.

  • Publication number: 20180349727
    Abstract: A positioning server is connected to a collection of access points, base stations, NFC stations, and image or video cameras and the collected data is used for positioning objects. A plurality of electronic devices are paired with an object by tracking the position of the object based on imaging and the position of electronic devices based on RF signals in vicinity of the object. Once a device is paired with an object, the propagation channel profile measured through the electronic device is used to develop and tune a database of channel profiles versus location. This database is used based on signature/profile matching and correlation for positioning devices and objects that do not have pairing or have poor image-based positioning accuracy or reliability. When a device is detected that cannot be paired with any object, or a device that is unpaired from a previously associated object, a theft or loss alert is generated.

  • Publication number: 20180343253
    Abstract: A security device may be utilized to provide security measures to an electronic device that may incorporate the security device or be coupled to it. The security measures may comprise authentication (e.g., authentication of devices, users, or activities), and/or encryption measures (e.g., encrypting or decrypting exchanged data). A transaction or access via the security device may be authenticated by communicating an authentication request by the security device to an authentication server, which may generate, in response, a sequence of information requests that are sent to the security device. The security device may then generate, in response, a sequence of responses that are sent to the authentication server, with the sequence of responses comprising a sequence of reported values each of which are unique. The authentication server may then authenticate the security device based on comparing of the sequence of reported values with a sequence of expected values that identifies the security device.
