Abstract: Aspects of the disclosure relate to generating or updating an access point model. The model may be generated based in part on access point model data, e.g., collected scan information from devices that travel through an indoor space. The wireless access point model may include an indoor map of a location or building. At some point, it may be determined that the access point model data may not meet a predetermined quality threshold. For example, the data may be outdated or inaccurate. A request is generated and transmitted to a client device within a predetermined distance of the access point associated with the access point model. In response to the request, the device travels to the indoor space associated with the access point to collect scan information. The scan information is used to update or otherwise modify the access point model.

Abstract: A staged camera traversal for navigating a virtual camera in a three dimensional environment is provided. The staged camera traversal can include a launch stage and an approach stage. During the launch stage, the tilt angle can be decreased towards zero tilt (i.e. straight down) with respect to the vertical. During an approach stage, the tilt angle of the virtual camera can be increased from about zero tilt towards the tilt angle associated with a target location. In certain implementations, the staged camera traversal can further include a traversal stage occurring between the launch stage and the approach stage. The tilt angle of the virtual camera can be maintained at about zero tilt during the traversal stage. The approach path of the virtual camera can be aligned along a view direction associated with the target destination during the approach stage.

Abstract: Systems and methods of cryptographically protecting location data transferred between servers via a network to tune a location engine are described herein. A first encryption module determines a first hash value for each location determination, encrypts the first hash value for each location determination using a first encryption protocol to generate a first encrypted data set, and transmits the first encrypted data set to a server. The first encryption module receives, from the server, a second encrypted data set with second hash values generated by a second encryption module of the server using a second encryption protocol. The first encryption module creates a first double encrypted data set from the second encrypted data set. A tuner compares the first double encrypted data set with a second double encrypted data set received from the server to adjust the location engine.

Abstract: Embodiments relate to censoring audio data. A censoring system receives audio data including a song tag and amplitude data as a function of time. The amplitude data represents spoken words occurring over a duration, as well as non-spoken word sound overlapping with some of the spoken words during the duration. The system accesses a set of song lyrics and processes the set of song lyrics and the amplitude data together to identify timestamps in the amplitude data. These timestamps indicate a time during the duration when one of the words from the lyrics begins in the amplitude data. The system compares the words in the set of song lyrics to a blacklist and adjusts the amplitude data at the timestamps of blacklisted word occurrences to render the audio at the blacklisted words incomprehensible. The system outputs the adjusted amplitude data.
