A method, an apparatus, and a computer program product are provided. The apparatus may be a UE. The UE has a screen display. The UE displays a first image of a first application on the screen display. The UE receives a selection of a first area of the screen display. The UE retains a first image section of the first image displayed in the first area. The UE receives a second image of a second application. The UE displays the first image section on the screen display at a second area of the screen display. The UE displays the second image in areas of the screen display other than the second area.

Retaining user selected screen area on user equipment

Methods, devices, systems, and non-transitory process-readable storage media for using secure elements to authenticate a data source device for providing reporting data to a recipient device via local point-to-point communications. An embodiment method includes operations performed by a secure processor of a recipient device that include generating a random token, a data encryption key, and a control register, encrypting the generated data using a shared encryption algorithm and a secret key associated with a unique identifier of the data source device, decrypting data re-encrypted by the data source device and sent within a response message using the shared encryption algorithm and the secret key, determining whether decrypted data matches the random token, and identifying the data source device is authenticated in response to determining that decrypted data matches the random token. The unique identifier and secret key may be pre-loaded on the recipient device.

Using secure elements to authenticate devices in point-to-point communication

A method for switching a Universal Integrated Circuit Card (UICC) transmission protocol includes: setting an operational mode of the UICC to an ISO 7816-12 USB UICC transmission protocol mode (USB mode); and in response to a user input, enabling the UICC to fallback from the USB mode to an ISO 7816-3 T=0/T=1 transmission protocol mode (ISO mode).
