Abstract: In some aspects, a computing system is configured to use graph-based techniques to detect synthetic identities. The computing system can generate a collection of graphs based on account data and transaction data for online entities. The collection of graphs includes multiple graph communities, each graph community including nodes and edges. Each node represents a user and an edge between a first node and a second node indicates a user represented by the second node is an authorized user of the user represented by the first node. The computing system can identify a clique graph community in the collection of graphs and compare the identified clique graph community with a known clique graph community that includes synthetic identities. The computing system can determine nodes in the identified clique graph community to be synthetic identities based on determining that the identified clique graph community is equivalent to the known clique graph community.

Abstract: A system may have an exterior display. The exterior display may display symbols that correspond to intended actions for the system or instructions for nearby viewers. The exterior display may include an array of light-emitting diodes, a collimator, a one-way filter to prevent sunlight from washing out the display, and a cover layer. The one-way filter may include a microlens array and a masking layer. The collimator is configured to collimate light from the array of light-emitting diodes and provide the collimated light to the one-way filter. The microlens array receives the collimated light and focuses the collimated light through a plurality of holes in the masking layer. In this way, the majority of display light is passed through the one-way filter towards a viewer. However, the majority of ambient sunlight is blocked by the masking layer, thus preserving a high contrast for the exterior display even in bright sunlight.

Abstract: In some aspects, a computing system can detect synthetic identities based on attributes associated with online entities. The computing system can generate entity links between primary entity objects and a secondary entity object. The secondary entity object identifies a target consumer as a secondary entity for accounts identified by the primary entity objects. Attributes of the secondary entity object and attributes of the primary entity objects can be calculated and compared to determine an inconsistency between a combination of a name attribute value and an address attribute value of the secondary entity object as compared to the primary entity objects. A fraud warning indicating that the target consumer is likely to be a synthetic identity can be generated based on the inconsistency and other attributes of the target consumer, such as an inquiries attribute, a terminations attribute, a duration attribute, and so on.

Abstract: To enable a display to display different content to different viewers, a display may include a time-sequential directional backlight unit. The backlight unit may emit light in different directions in different configurations. In a first state, the backlight unit emits light at maximum brightness in a first direction. In a second state, the backlight unit emits light at maximum brightness in a second direction that is different than the first direction. The backlight unit may repeatedly and rapidly switch between the different states. The first direction may be towards a first viewer whereas the second direction may be towards a second, different viewer. Therefore, each viewer receives backlight in one of the configurations and does not receive backlight in the other configuration. In synchronization with the backlight unit, the liquid crystal display panel may repeatedly switch between displaying content for the first viewer and displaying content for the second viewer.
