Provided is a video playback system based on approval of a playback approver. A decryption key that can decrypt an encrypted and stored recorded video is generated only when video playback is approved by a playback approver using an appointed playback approval method and transmitted to the video recording device so that it is possible to prevent leakage of the recorded video with sensitive personal information.

A method and apparatus for secure multimedia transfer provides an encrypted data transfer system that makes transferring multimedia content from a client to any incompatible system or to a system outside the location of the client very difficult.

A system and method for securely delivering and updating media using portable storage. In one embodiment, field-modifiable storage presents itself to the host system as a read-only standardized media player, where the user adds, replaces, or updates media onto that storage. A further embodiment establishes encrypted streaming from field-modifiable storage directly into the graphics processor of the viewing host, bypassing the general-purpose computing infrastructure.

Aspects of the subject disclosure may include, for example, a user device that attaches to a radio access network of a mobile network and requests services. The user device creates a virtual network function on the device to support the service. The virtual network function may include a user plane virtual network function, a control plane virtual network function, or both. Other embodiments are disclosed.

To appropriately perform connection between information processing devices. The information processing device is an information processing device including a communication unit and a control unit. The communication unit is configured to perform image transmission to a first information processing device by using wireless communication. The control unit is configured to temporarily suspend the first information processing device and perform an authentication process with a second information processing device having a different role from the first information processing device if the second information processing device is newly connected when transmitting the image to the first information processing device.

Aspects of the subject disclosure may include, for example, predicting opportunities for a mobile communication device to access a network via available pathways during a first time period according to a history of network connectivity of the mobile communication device, selecting a first pathway of the available pathways according to the opportunities that are predicted for the mobile communication device to access the network via the available pathways during the first time period, and directing transmission of first data to the mobile communication device via the first pathway during the first time period, wherein a presence of a second data at the mobile communication device enables an application to access the first data at the mobile communication device. Other embodiments are disclosed.
