Abstract: A map-based graphical user interface for a social media application displays to social media activity information based on submission of geo-tagged social media items to the platform. Geographical distributions of social activity is displayed on a map forming part of the application. A heatmap can represent posting density or unusualness.

Abstract: Techniques and systems for the dynamic generation of a map interface include generating temporal activity models by representing individual social media postings as having respective density distributions in time. Each posting's temporal density distribution spans multiple sequential time windows centered on the posting's timestamp, with density contributions decreasing in value for time windows further from the timestamp. The temporal models may be combined with spatial density distributions to generate comprehensive geo-temporal representations of social media activity. A graphical user interface displays an interactive map with overlay elements determined based on calculated activity attributes, including detected temporal patterns and anomalies identified by comparing current activity models against historical baselines. The modeling approach enables improved visualization of activity patterns while providing inherent privacy protection through probabilistic representation of individual posts.

Abstract: Systems and methods for generating and serving stylized map tiles for a social media platform's map-based graphical user interface. Multiple earth imagery tiles corresponding to a geographical area are retrieved, each comprising a photographic image of a corresponding portion of the Earth's surface. Based on the earth imagery tiles, multiple stylized map tiles are generated. In response to receiving a request from a user device for display of a target area in the map-based GUI, a set of stylized map tiles corresponding to the target area is retrieved and transmitted to the user device. The generation of stylized map tiles may include retrieving a target earth imagery tile together with neighboring tiles, generating an expanded earth imagery tile, stylizing the expanded tile, and cropping to produce the final stylized map tile. Different neural networks may be used for stylizing tiles at different zoom levels.

Abstract: Systems, devices, media, and methods are presented for device independent secure messaging. The systems and methods generate an encrypted message by encrypting message content, designated for a specified recipient, with an encryption key. The systems and methods select a set of recipient keys, associated with the specified recipient, from a plurality of member keys. For each recipient key, the systems and methods encrypt the encryption key to generate a set of encrypted keys and transmit the encrypted message and an encrypted key of the set of encrypted keys to one or more client devices associated with the specified recipient. The systems and methods then receive an acknowledgement indicating a termination status of the encrypted message.

Abstract: A server system for a map-based social media platform maintains user location information to enable the rendering of friend icons on a map at a corresponding display locations. The system maintains a per user access control list (ACL) that lists all users whose icons can be viewed by a requesting user. The ACL can include a designation of respective display granularity levels for different friend users.

Abstract: In a graphical user interface (GUI) for a social media platform, social media content is surfaced with variable visual attributes based on activity metrics. In a GUI for a social media platform, where the GUI provides access to posted social media items, an activity metric is determined for the underlying social media activity associated with each of multiple collections of social media items. The GUI displays user-selectable interface elements, such as icons, corresponding to these collections, with each icon having a visual attribute that varies depending on the activity metric. This results in visual differences between collection icons based on differences in their corresponding activity metrics.

Abstract: A map-based graphical user interface for a social media application displays to special social media activity information based on submission of geo-tagged social media items to the platform. For users and or submitted items that need predefined location fuzzing criteria, such activity is represented in the graphical user interface at an intentionally inaccurate position.

Abstract: Among other things, embodiments of the present disclosure improve the functionality of electronic messaging and imaging software and systems by determining the current activities of users based on location sensor information from the users' computing devices and generating customized media content items based on their activities. The media content can be generated for a variety of topics and shared with other users. For example, media content (e.g., images or video) can be generated and displayed on a user's computing device, as well as transmitted to other users via electronic communications, such as short message service (SMS) or multimedia service (MMS) texts and emails.

Abstract: A tracking system is provided that tracks user browsing activity while maintaining user privacy. It is determined whether a cookie is stored in local storage of a client device. If the cookie is not stored: a tracking identification (ID) is generated; the tracking ID, a cookie rotation timestamp, and a failed request counter in a generated cookie is stored; and the generated cookie is copied and attached to a transmitted event. If the cookie is stored: it is determined whether a time indicated by a stored cookie rotation timestamp is in the past; if the time is in the past, a flag requesting a new cookie value is set for a transmitted event; and if the time is not in the past, the stored cookie is copied and attached to a transmitted event.

Abstract: Systems, devices, media, and methods are presented for retrieving authentication credentials and decryption keys to access remotely stored user-generated content. The systems and methods receive a first authentication credential and access a second authentication credential based on receiving the first authentication credential. The system and methods generate an authentication token and an encryption token. Based on the authentication token, the system and methods access a set of encrypted content and an encrypted content key. The systems and methods decrypt the encrypted content key using the encryption token and decrypt the set of encrypted content using the decrypted content key. At least a portion of the content is presented at the user device.
