Abstract: Passive display devices such as a passive magnifying device (e.g., a screen magnifier) or a projector (e.g., a built-in mobile phone projector) are useful in enlarging photos, documents, videos, etc. for view for small-sized small-screen device screens. However, optimal content resolution for the small-screen device screens may not be optimal for the passive display devices. Particularly, when a small-screen device receives content from a remote computing device, the initial content resolution may not be optimal even for the small-screen device screen because of low transmission speed and/or low bandwidth of a connection with an original data source. Content resolution adjustment may be performed by determining distance between the passive display device and the small-screen device, calculating magnification ratio for the passive display device, and adjusting the content resolution based on the calculated magnification ratio.

Abstract: A system and method for providing multifactor authentication. A disclosed method includes receiving a request at a server to launch a new session for an application on a client device, generating a plurality of codes, each of the plurality of codes associated with a respective identifier, and forwarding the plurality of codes via a short messaging service (SMS) message to a user associated with the client device. The method further includes sending the respective identifier associated with a given code of the plurality of codes to the application and receiving a submitted code entered into the application from the client device. Once received, the method compares the submitted code with the given code associated with the respective identifier and authenticates the user in response to the submitted code matching the given code.

Abstract: Methods and systems for content resolution adjustment for passive display devices are described herein. Passive display devices such as a passive magnifying device (e.g., a screen magnifier) or a projector (e.g., a built-in mobile phone projector) are useful in enlarging photos, documents, videos, etc. for view for small-sized small-screen device screens. However, optimal content resolution for the small-screen device screens may not be optimal for the passive display devices. Particularly, when a small-screen device receives content from a remote computing device, the initial content resolution may not be optimal even for the small-screen device screen because of low transmission speed and/or low bandwidth of a connection with an original data source. Content resolution adjustment is provided in this disclosure by determining distance between the passive display device and the small-screen device, calculating magnification ratio for the passive display device, and adjusting the content resolution based on the calculated magnification ratio.

Abstract: Described embodiments may provide transferring a file to a mobile device via scanning quick response codes displayed via a display output device. A media device in communication with a server may receive a request to access a file on the server. A file converter of the media device may encode the file obtained from the server into a plurality of quick response (QR) codes. The media device may display the plurality of QR codes via a display output device. A mobile device may scan each of the plurality of QR codes displayed on the display output device. A file downloader of the mobile device may interpret each of the scanned plurality of QR codes to form a file on the mobile device.

Abstract: Described embodiments provide systems and methods for provisioning disk images on remote devices. Described is a device configured to connect to a pre-configured network upon device start-up, transmit a request to a server at a pre-configured network address, receive a response containing a disk image for the device, and populate a memory component of the device with the disk image received. Described is a server configured to, responsive to receiving a request from a device, authenticate the request, identify a disk image corresponding to the device, and transmit the disk image to the device. These systems and methods are well suited for improving security and integrity of deployed special-purpose devices, e.g., as may be used for an “Internet of Things” deployment.

Abstract: Methods and systems for enhanced QR code security are described herein. A computing platform may generate a QR code that includes an information code and a server code. The computing platform may split the QR code into first and second portions, where the first portion includes at least the server code. The computing platform may send, to a QR display device, the first portion for display. The computing platform may receive, from a user device, authentication credentials and a request for the second portion, sent to the computing platform based on identification of the computing platform through scanning, by the user device, the server code at the QR display device. The computing platform may send, based on validating the authentication credentials and to the user device, the second portion, where the user device is configured to re-assemble the QR code based on the first and second portions.
