Portable Security Device for Secure Internet Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network security solutions are inadequate for providing secure Internet access to user devices operating in unsecure network environments, such as public Wi-Fi, where they are vulnerable to eavesdropping and malware threats like browser hijacking and keylogging.
Innovation Solution
A portable security device establishes a first secure direct wireless connection with the user device and a second secure connection to a security server, functioning as an Internet gateway, using protocols like VPN to encrypt data and provide secure Internet access, while also managing user authentication and dynamically adjusting security settings based on network and device characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If known security solutions (firewalls, antivirus, cloud detection) are used, then basic security protection is provided, but sufficient security in unsecure network environments is not achieved
Solution Approach 1:
The patent introduces a portable security device as an intermediary between the user device and the unsecure network. This device establishes secure connections (VPN tunnels) to act as a mediator that protects data from eavesdropping and malware while allowing network access. The security device intercepts and encrypts traffic before it reaches the unsecure network, resolving the contradiction by adding a protective layer without blocking necessary network functionality.
2Ease of operation
If user devices connect directly to unsecure networks for Internet access, then network accessibility is achieved, but data transmitted is exposed to eavesdropping and malware
Solution Approach 1:
The portable security device serves as an intermediary that maintains network accessibility while protecting data. It establishes secure VPN connections that allow Internet access to continue functioning normally, but all data traffic is encrypted and routed through the security device, preventing exposure to eavesdropping and malware on unsecure networks.
Solution Approach 2:
The security device performs preliminary security actions by establishing encrypted connections before data transmission occurs. It proactively creates secure tunnels and implements security measures in advance, preventing data exposure before eavesdropping or malware attacks can occur, thus protecting information while maintaining ease of network access.
3Reliability
If security connections are established through additional network modules and protocols, then secure Internet access is provided, but device complexity increases
Solution Approach 1:
The patent segments the security function into a separate portable security device that can be independently deployed. Instead of integrating complex security modules into every user device, the security functionality is segmented into a dedicated device that handles encryption, VPN connections, and security protocols, thereby providing secure connections without burdening the user devices with increased complexity.

AI summary
Disclosed herein are systems, methods and computer program products for providing secure Internet access to a user device in an unsecure network environment, such as a public wireless network. The system includes a portable security device configured to establishing a first secure direct wireless connection with the user device and a second secure network connection through the public wireless network to a security server, which provides Internet access. The security device provides Internet browser and e-mail application, which can be used instead of unsecure applications of the user device to access Web resources through the first and second secure network connections. In addition, the security device includes a secure keyboard, which can be used by the device user instead of the unsecure keyboard of the user device to enter user authentication data for accessing the desired Web resources.
