Protecting personal information upon sharing a personal computing device

摘要

In particular embodiments, a temporary user is able to use another's personal computing device in shared mode for a short period of time while experiencing a personalized user interface. An indication is detected that a personal computing device associated with a primary user is to be shared with a temporary user. Access to local personal information associated with the primary user is disabled if it is stored on the personal computing device. Access to remote personal information of the primary user that is accessible from the personal computing device is disabled. A personalized user interface incorporating personal information associated with the temporary user is presented on the personal computing device for the temporary user. Personal information of the primary user is not accessible by the temporary user, and vice versa. When shared mode is to be terminated, all personal information of the temporary user is deleted.

主权项

1. A method comprising:
detecting, by a personal computing device associated with a primary user, an indication that a temporary user is about to log in to the personal computing device; disabling, by the personal computing device, access to local personal information associated with the primary user that is stored on the personal computing device; disabling, by the personal computing device, access to remote personal information associated with the primary user that is accessible from the personal computing device; receiving, by the personal computing device, authentication information provided by the temporary user; by the personal computing device, in response to receiving the authentication information:
logging the temporary user in to the personal computing device based at in part on the provided authentication information; andretrieving, from a server, based at least in part on the provided authentication information, remote personal information associated with the temporary user; presenting, by the personal computing device, a personalized user interface on a screen of the personal computing device for the temporary user, wherein the personalized user interface comprises at least a portion of the retrieved personal information; detecting, by the personal computing device, an indication that access to the personal computing device by the temporary user is to be disabled; disabling, by the personal computing device, access to local personal information associated with the temporary user that is stored on the personal computing device; disabling, by the personal computing device, access to the remote personal information associated with the temporary user; detecting, by the personal computing device, authorization from the primary user to restore access to the local and remote personal information associated with the primary user; restoring, by the personal computing device, access to the local personal information associated with primary user; and restoring, by the personal computing device, access to the remote personal information associated with the primary user.
