A method provides device access security via use of periodically changing Quick Response (QR) codes. The method includes: generating () a first authentication QR code and assigning () the generated QR code as the current authentication mechanism for accessing the device. Contemporaneously with the generation of the QR code, at least one QR code validity parameter is established () to define when access to the device can be provided to a second device that provides the correct authentication QR code along with the access request. The method includes, in response to a pre-defined trigger () of the QR code validity parameter: generating () a new authentication QR code, different from a previously generated authentication QR code; assigning () the new authentication QR code as the current authentication mechanism for accessing the device; and enabling access to the first device to only second devices that provide the current authentication QR code.

Device security utilizing continually changing QR codes

A device-to-device (D2D) pairing assembly comprises: a first and a second device detecting and communicating (DDC) component communicatively coupled to each other and to a microprocessor that executes a device pairing parameter exchange (DPPE) utility, which configures the D2D pairing assembly to: detect a communicative coupling of a first user device to the first DDC component; receive from the first user device at least one first pairing parameter, which first pairing parameter enables another device to connect to and participate in a pairing session with the first user device; detect a communicative coupling of a second user device to the second DDC component; and communicate the at least one first pairing parameter to the second user device, via the second DDC component, to trigger the second user device to connect to and participate in a pairing session with the first user device via a direct device-to-device communication channel.

An electronic device () includes a control circuit () that is operable with a memory or storage device (). The electronic device includes an RFID tag () having a second memory (). The RFID tag can be read from, or written to, by a RFID communication device () when the electronic device is OFF. Device personalization can be achieved when the control circuit accesses the second memory to retrieve the device configuration data during a boot sequence and configures the electronic device in accordance with the device configuration data retrieved from the second memory during the boot sequence. Device information can be made available when the electronic device is OFF by writing the device information to the second memory.

A first user equipment (UE) includes a display, at least two communication mechanisms that respectively supports a first and a second communication mode, and a processor communicatively coupled to the display and the communication mechanisms. The first UE further includes a failed pairing notification (FPN) utility that configures the first UE to: initiate communication with a second UE via a first communication mode; and in response to a trigger condition indicating that the first communication mode is not supported at either the first UE or the second UE, generate a notification alerting a user of the first UE that (1) a different communication mode is required for the first UE to communicate with the second UE and (2) an authorization QR code is required to be exchanged between the first UE and the second UE as an authentication mechanism before the communication can be established via the different communication mode.
