Secure pairing of computing devices, such as a field tool and a battery-powered device (BPD), may include generating by the BPD a challenge message including a randomly-generated challenge, and receiving at the field tool a challenge message from the BPD via a Bluetooth low-energy (BLE) advertisement message. The challenge message can include a randomly-generated challenge and can be issued in a scannable undirected advertising message. The challenge key can be calculated via a secure hash algorithm (SHA) to obtain a response solution. The response solution can be sent by the field tool to the advertising device in response to the challenge message. The response solution can be verified by the BPD using a cryptographic message authentication code such as an HMAC, and the BPD sends a confirmation message to the field tool indicating that the response solution is verified as correct.

A system for processing information requests associated with mobile devices comprises an evaluation module configured to determine at least one performance measure for each of a plurality of information documents using at least data in one or both of a requests database and events database. The at least one performance measure includes at least one of an impression-based performance measure, a click/call-based performance measure, and an off-line site-visit-based performance measure. The system further comprises an information server configured to select a first information document for transmitting to a first mobile device to fulfill a first request. The information server includes a volume control unit configured to derive an off-line site visit projection in response to the first document being selected based at least in part on an off-line site-visit-based performance measure and having been impressed on the first mobile device, and to adjust a budget associated with the first document using the off-line site visit projection.

Tracking devices can be associated with safe zones, smart zones, and high risk zones. Safe zones correspond to regions where a likelihood that a tracking device is lost within the safe zone is lower than outside the safe zone. High risk zones correspond to regions where a likelihood that a tracking device is lost within the high risk zone is higher than outside the high risk zone. Smart zones correspond to an expected tracking device, mobile device, or user behavior. Home areas are geographic regions in which a user resides, and travel areas are geographic regions in which a user does not reside. A tracking device can be configured to operate in a mode selected based on a presence of the tracking device within a safe zone, a smart zone, a high risk zone, a home area, or a travel area.

The disclosure relates to technology for determining locations of approaching recipients of online pre-requested or pre-ordered goods/services. Physical waiting queues and/or wait-lists are managed so that the goods/services will be provided without excessive wait times or unacceptably long wait lines or inferior quality in the provided goods/services. Resolution of location determination becomes finer and finer in one embodiment as the recipients get closer to the provisioning spot. If there is a change of plans, the recipients are notified ahead of time so as to avoid last minute surprises or disappointments.

Physical waiting queues and/or wait-lists are managed so that the goods/services will be provided without excessive wait times or unacceptably long wait lines or inferior quality in the provided goods/services. Resolution of location determination becomes finer and finer in one embodiment as the recipients get closer to the provisioning spot. If there is a change of plans, the recipients are notified ahead of time so as to avoid last minute surprises or disappointments.

Methods and systems for content management are described. If programming content is distributed to viewers, signals are transmitted with the programming content to indicate a segmentation in the programming content. If a user device sees the signal indicating the advertisement break, the use device may make a request to an advertisement server. The advertisement server may receive the request and determine an identifier associated with the request and an identifier associated with an advertisement break. A binder may bind the identifier associated with the request and the identifier associated with the advertisement break.

A system and method for sales promotions via a text-messaging with deferred text-to-call interaction comprising a call-to-action link, generated via a script contained in the header of a webpage, which reduces the number of steps needed to obtain a sales promotion via a website. The call-to-action link triggers a prepopulated text message on a user's mobile device. User response to this message initiates a routing protocol to connect the user to a seller or agent associated with the advertising company for voice-based interaction. A pre-authorization message may be sent by the chatbot with a request for authorization to access private data. In some embodiments, a deferred text-to-call feature is implemented which allows the user to make an audio connection with an advertiser at a future time.

Systems, methods, and apparatus are described herein for determining a location from anonymous data. For example, a computing device may receive anonymous data associated with a browser session initialized by a user via a browser on a user computing device. The computing device may determine that the user has not been assigned a unique identifier. The computing device may determine whether the user opted-in to location tracking. If the user opted-out of location tracking, the computing device may determine a latitude coordinate and a longitude coordinate of the user computing device during the browser session. The computing device may identify a physical address for the user based on the latitude coordinate and the longitude coordinate, for example, using a map application programming interface (API). The computing device may assign the unique identifier to the user. The computing device may associate the unique identifier to the physical address.

A live image providing system according to an embodiment of the present disclosure provides a real-time live image of each specific location. The live image providing system includes a plurality of image provider terminals transmitting real-time image data containing an external view of a specific location and location information on the specific location, a live image service user terminal requesting for the real-time image data on the specific location, and a platform server transmitting to the live image service user terminal real-time image data of an image provider terminal having location information corresponding to the specific location when receiving a message requesting for the real-time image data on the specific location from the live image service user terminal.
