Secure Place-Shifting via Mobile Security Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multimedia content processing devices and place-shifting systems lack sufficient security to protect premium content from unauthorized access and do not allow secured access to premium content from remote or place-shifted locations.
Innovation Solution
A system that uses a mobile end user communication device to create security binding and upload application software to a temporary hosting device, establishing a secure place-shifting session bound to the portable device, enabling secure remote access to protected digital material from a personal or private network, with authentication via user PIN and secure data tunnel management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If place-shifting features are implemented to allow remote access to multimedia content, then accessibility and convenience are improved, but security and protection of premium content deteriorate
Solution Approach 1:
Security binding information is created and stored on the portable communication device before the user travels to a remote location. This preliminary establishment of security credentials enables the device to automatically authenticate and establish secure connections when accessing content at remote locations, resolving the contradiction by preparing security measures in advance rather than attempting to establish them during remote access.
Solution Approach 2:
A portable communication device serves as an intermediary carrier that transports security binding information between the home location and remote locations. This intermediary device holds the security credentials and uses them to authenticate the user and establish secure sessions, thereby enabling remote access while maintaining content protection through the mediating security layer.
2Reliability
If security binding information is stored on a portable communication device to enable secure remote access, then security and content protection are improved, but device complexity and security management overhead increase
Solution Approach 1:
The portable communication device automatically uses the stored security binding information to authenticate itself and establish secure sessions without requiring manual security configuration by the user. The device self-manages the security credentials, performing automatic authentication and session establishment, which reduces the perceived complexity for users while maintaining robust security.
Solution Approach 2:
The portable communication device serves multiple functions: it acts as a universal carrier for security binding information, an authentication credential, and a session manager across different remote locations and devices. This multi-functionality consolidates security management into a single device, reducing overall system complexity despite the enhanced security capabilities.

AI summary
A method, system and device for providing secure access to multimedia content received by a networked digital storage device, such as a set-top box. A mobile device, such as a mobile telephone, obtains appropriate security binding information and application software when coupled to the networked digital storage device at its end user location. The mobile device uploads the security binding information to a randomly located temporary hosting device at its place-shifted location when coupled thereto and, through a logical binding with the temporary hosting device, enables a secure, remote session. The secure binding and transfer of appropriate keys allow the remote hosting device to securely access premium or protected digital material/services available at the networked digital storage device. After completion of the secure, remote access session, termination occurs and the security binding information and the computing activity residue can be removed from the mobile device and the temporary hosting device.
