Anti-virus Chip Isolates Boot Sector Viruses via Pre-Transmission Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anti-virus software is ineffective in preventing the spread of boot-type viruses, as they can infect electronic devices through external devices connected to a connection port, and existing solutions fail to eliminate such viruses once the device is infected.
Innovation Solution
An anti-virus chip with connection terminals, a detection unit, and a processing unit is integrated between the connection port and the system circuit of an electronic device, which performs a virus-scan on external devices before establishing a transmission path, preventing the spread of viruses by not connecting infected devices to the system circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the operating system automatically connects to external devices and reads all files, then data access efficiency is improved, but the risk of virus infection increases
Solution Approach 1:
The patent introduces an anti-virus chip as an intermediary component between the connection port and the system circuit. This chip performs virus detection on external devices before allowing data transmission, thereby blocking virus infection while maintaining efficient data access. The anti-virus chip acts as a mediator that filters harmful content while permitting legitimate data flow.
Solution Approach 2:
The patent implements preliminary virus detection before establishing data transmission paths. The anti-virus chip scans external devices for viruses prior to allowing the operating system to access files, preventing infection before it can occur. This preliminary security check ensures that subsequent data access operations remain efficient and safe.
2Measurement precision
If anti-virus software is installed on the operating system, then virus detection capability is improved, but the ability to prevent boot-type viruses is reduced
Solution Approach 1:
The patent segments the virus protection function into two distinct layers: the anti-virus software running on the operating system for general virus detection, and the anti-virus chip at the hardware level for preventing boot-type viruses. This segmentation allows each layer to specialize in different types of threats, with the hardware chip providing reliable protection against boot-sector infections that software cannot prevent.
Solution Approach 2:
The anti-virus chip serves as a hardware intermediary between the connection port and system circuit, performing virus detection independently of the operating system. This hardware-based detection mechanism is particularly effective against boot-type viruses, as it intercepts and analyzes data before it can reach the system's boot sector, providing protection that software-based solutions cannot achieve.
3Speed
If a transmission path is established immediately upon connection, then data transfer speed is improved, but virus spread risk increases
Solution Approach 1:
The patent implements preliminary virus detection before establishing the transmission path. The anti-virus chip scans the external device for viruses immediately upon connection, and only after confirming the device is safe does it enable the transmission path between the connection port and system circuit. This approach ensures rapid data transfer speeds while eliminating virus spread risk.
Solution Approach 2:
The anti-virus chip acts as a controllable intermediary that manages the transmission path. It monitors data flow between the connection port and system circuit, dynamically enabling or disabling the path based on virus detection results. This intermediary control mechanism maintains high data transfer speeds for legitimate devices while blocking virus transmission.
Data Source
AI summary
An anti-virus chip includes a first connection terminal, a second connection terminal, a detection unit and a processing unit. The first connection terminal and the second connection terminal are respectively coupled to a connection port and a system circuit of an electronic device. The detection unit detects whether the connection port is connected to an external device via the first connection terminal. When the detection unit detects that the connection port is connected to the external device, the processing unit performs a virus-scan program on the external device to determine whether a virus exists in the external device. When determining that a virus does not exist in the external device, the processing unit establishes a first transmission path between the first connection terminal and the second connection terminal. When determining that a virus exists in the external device, the processing unit does not establish the first transmission path.
