Multi-tenant hosting of inverted indexes for text searches is implemented. Text search requests are routed to different index nodes that cache inverted indexes for different user accounts. Updates to inverted indexes are routed to index nodes that have acquired a lock on an inverted index. The index nodes have access to a common data store that persistently stores the inverted indexes.

A system and method for performing image-based authentication requires users to enter an image-based password in order to access a secure system or network. A user may identify at least one password image, and may enter the system or network if he or she selects each of the password images shown in a group of images on the display. Additionally, the user may designate specific locations for multiple password images on a user interface, and a user may enter the system or network if he or she locates each of the password images in its designated location on the user interface.

A computing resource service provider may operate a build service configured to store data object on behalf of a customer of the computing resource service provide. The build service may receive a stream of data objects including object objects that reference one or more other data objects. A Bloom filter may be used to determine whether a one or more referenced data objects have been previously processed by the build service. This may enable the build service to reorder processing of the data object based at least in part on whether the one or more referenced data objects have previously been processed by the build service.
