Overcoming Limitations Of Signature Scanning -Applying Triz To Improve Anti-Virus Programs, Umakant Mishra Jan 2012

Overcoming Limitations Of Signature Scanning -Applying Triz To Improve Anti-Virus Programs, Umakant Mishra

Umakant Mishra

A virus signature is a sequence of bytes that may be found in a virus program code but unlikely to be found elsewhere. Signature scanning is a method of detecting a virus by scanning a target program to detect the presence of any virus signature. If the signature is found then the target program is deemed infected, otherwise the target program is deemed uninfected.

Signature scanning is the most popular method of virus scanning and is adopted by all anti-virus programs. Signature scanning is capable of detecting more than 80% of viruses. It uses a simple logic and uses less …


Improving Speed Of Virus Scanning- Applying Triz To Improve Anti-Virus Programs, Umakant Mishra Jan 2012

Improving Speed Of Virus Scanning- Applying Triz To Improve Anti-Virus Programs, Umakant Mishra

Umakant Mishra

As the number of viruses increases the amount of time to scan for those viruses also increase. This situation is worsened because of the increasing number of files typically stored in a computer system. Besides more complex tests are required to detect the modern day’s intelligent viruses. Thus a combination of all these factors makes a full virus scan very lingering and resource consuming. With thousands of types of viruses and gigabytes of storages, a typical virus scanning may take several hours. Because of this reason many users don’t like to virus scan their computers unless so required.

Detecting Boot Sector Viruses- Applying Triz To Improve Anti-Virus Programs, Umakant Mishra Jan 2012

Detecting Boot Sector Viruses- Applying Triz To Improve Anti-Virus Programs, Umakant Mishra

Umakant Mishra

The boot sector virus infects the boot record of the hard disk or floppy disks. It gets loaded onto the memory every time the computer is booted and remains resident in the memory till the computer is shut down. Once entered it alters the boot sector of the hard disk and remains in the hard disk permanently until the system is totally damaged and fails to boot.

While analyzing the problem from TRIZ prospective we try different possibilities to avoid boot sector viruses, such as, Can we do away with boot record? Can we avoid booting from floppies? Can we …

Constructing New Technology: The Crop Circle Gps Cart In Pictures, Gregory Keith Bartley Jr., Brandon J. Horvath

Gregory Keith Bartley Jr.

The crop circle spectrometer represents a breakthrough in unbiased sensor data. Unlike traditional passive sensors, it pulses light at a speed of 20,000 times per second. With this comes the ability of these filters to discern reflectance measurements from that of natural sunlight, allowing it to be used in environments of sun, shade, and even darkness. From these various reflectance values at different wavelengths, we get measurements of plant health known as vegetation indices. And different vegetation indices can tell us different things about the health of a plant. Couple this with the recent advances in GPS technology, we can …

An Introduction To Virus Scanners, Umakant Mishra

Umakant Mishra

The main functions of an anti-virus program are, (i) Virus prevention and file protection, (ii) Virus scanning and detection, (iii) Removing virus from infected files, and (iv) Recovering damaged files and objects.

An anti-virus program employs various methods to detect and remove viruses. The two popular methods of detecting viruses are signature scanning and behavior monitoring. However each of these methods has its strengths and weaknesses.

As the detection gets more sophisticated so are the virus programmers. The virus programmers also try to go one step beyond the anti-virus mechanism and create intelligent viruses which pose more and more difficult …


Methods Of Virus Detection And Their Limitations, Umakant Mishra Aug 2010

Methods Of Virus Detection And Their Limitations, Umakant Mishra

Umakant Mishra

An anti-virus program typically employs various strategies to detect and remove viruses. The popular methods of detecting virus are signature scanning, heuristic scanning and integrity checking. However each of these methods has its own strengths and weaknesses.

Signature scanning (or searching of known virus patterns) is the most common method of virus detection. But it cannot detect viruses whose signatures are not available in the virus database. The other popular method is to use a heuristic algorithm to find viruses based on common behaviors. This method can be complex, but it has the ability to detect unknown or new viruses. …

Leading Firms As Knowledge Gatekeepers In A Networked Environment, Deogratias Harorimana Mr

Dr Deogratias Harorimana

This chapter introduces the role of the knowledge gatekeeper as a mechanism by which knowledge is created and transferred in a networked environment. Knowledge creation and transfer are essential for building a knowledge based economy. The chapter considers obstacles that inhibit this process and argues that leading firms create a shared socio-cultural context that enables the condivision of tacit meanings and codification of knowledge. Leading firms act as gatekeepers of knowledge through the creation of shared virtual platforms. There will be a leading firm that connects several networks of clients and suppliers may not interact directly with one another, but …

Using Triz For Maximizing Information Presentation In Gui, Umakant Mishra

Umakant Mishra

The modern software tools provide numerous graphic elements in their GUI, which demand more and more screen space. As the size of a display screen cannot be extended beyond a limit, it is typically seen as a constraint in a graphical user interface.

Looking from a TRIZ perspective, the computer screen should display all the information that the user needs (Ideal Final Result). There are various methods of addressing the problem of screen space, some of which are, ”using icons for windows”, “the desktop metaphor”, “the large virtual workspace metaphor”, “multiple virtual workspaces”, “overlapping windows” and “increasing dimensions” etc.

Using Triz To Improve Navigation In Gui, Umakant Mishra

Umakant Mishra

A typical user interface consists of several buttons, menus, windows, trees and other type of controls. The increased number of GUI elements and complexities of the GUI controls necessitate the user to acquire certain level of skill and efficiency in order to operate the GUI. There are many situations which further make the navigation difficult. Ideally the user should face no difficulties in navigating through the user interface. Any operation in the graphical user interface should require minimum pointer operations from the user (Ideal Final Result). This objective of a graphical user interface has led to several inventions trying to …


Using Triz For Minimizing Cursor Movements In Gui, Umakant Mishra Oct 2008

Using Triz For Minimizing Cursor Movements In Gui, Umakant Mishra

Umakant Mishra

Although a GUI is a revolutionary development over its predecessors, it suffers from a typical shortcoming that it requires a lot of pointer movements. As pointer movement is a slow process it affects the overall performance of a GUI operation. Besides too much pointer movement can frustrate a user. Hence, it is desirable to reduce the pointer movements while performing any action through a typical GUI. Ideally the user need not move the pointer to initiate a GUI based operation. In other words the pointer itself should automatically move onto the desired location on the graphical user interface (Ideal Final …

Inventions On Improving Visibility Of Gui Elements, Umakant Mishra

Umakant Mishra

The evolution of computing technology has witnessed tremendous growth in the processing power of the computer. The memory and storage capabilities are also increasing year after year. In contrast to the above, the display area of a PC monitor remains the same. This inhibits the productivity of a computer, as the user does not just have enough view area to interact with the computer. Ideally the display screen should accommodate all required data, objects and GUI elements for user interaction. If some data or object is hidden behind or remaining beyond the display area, it should automatically come to the …
