A user provides an identification (ID) signal (e.g. a biometric ID signal like a self-snapshot) to a trusted cloud-based provider. When the user attempts to authenticate with the cloud-based provider, a similar ID signal (e.g. another self-snapshot) for the user is captured and provided to the cloud-based provider. The cloud-based provider then obtains a secondary ID signal, or a combination of secondary ID signals, and utilizes the secondary ID signal, or signals, to identify a subset of user records to be searched for the ID signal. The subset of the records, rather than all of the user records, can then be searched for the ID signal. The cloud-based provider can then authenticate the user based on the results of the search of the subset of the user records. 用户向受信任的基于云的提供方提供标识(ID)信号(例如，如自拍的生物ID信号)。当用户尝试向基于云的提供方进行认证时，针对用户的类似ID信号(例如，另一自拍)被捕获，并且被提供给基于云的提供方。然后，基于云的提供方获取第二ID信号或多个第二ID信号的组合，并且利用一个或多个第二ID信号来标识用户记录的子集，该用户记录的子集要针对ID信号而被搜索。然后可以针对ID信号搜索记录的子集而不是所有用户记录。然后，基于云的提供方可以基于用户记录的子集的搜索的结果来认证用户。
