Abstract: An internet of things (“IoT”) device is disclosed that can be authenticated on a wireless local area network (“WLAN”) without human intervention. The IoT device can also authenticate itself with a network service without human intervention. In order to enable this functionality, data identifying a service set identifier (“SSID”) used by the WLAN, a digital certificate for use in authenticating on the WLAN, and a digital certificate for use in authenticating with a network service are stored in the IoT device at the time it is manufactured. The digital certificate for authenticating on the WLAN is stored at an authentication server and information about the digital certificate for use in authenticating with the network service is stored at the network service. The IoT device can use the SSID to connect to the WLAN and use the digital certificates to authenticate with the authentication server and the network service, respectively.

Abstract: A device analyzes text messages, email, and/or other data for the purposes of suppressing the display of sensitive content on a lock screen. For example, a device may prevent a lock screen from displaying a notification indicating the arrival of a message containing sensitive information. Alternatively, the device may filter any sensitive information from a notification indicating the arrival of a message. The techniques disclosed herein improve the security of a device by preventing the display of sensitive information on a lock screen, while also improving the usability of lock screen notifications by allowing other information to be displayed. The techniques disclosed herein also improve the security of other systems using the device as part of a multi-factor authentication process.
