A New Security System On Captcha Technology Essay

Biometrics technology aims at utilizing major and distinctive characteristics such as behavioral or biological, for the sake of positively indentifying people. With the help of a combination of hardware and specific identifying sets of rules, a basic human attribute, automated biometric recognition mimics to distinguish and categorize other people as individual and unique. But the challenges surrounding biometrics are great as well.

The authentication process is a necessity for safeguarding systems against various forms of security threats, such as password-cracking tools, brute-force or wordbook attacks, abuse of system access rights, impersonation of attested users, and last but not least reply attacks just to name a

Mathematical CAPTCHA- This CAPTCHA provides the user with a simple or complex mathematical equation, to proceed further in the process the user has to solve and answer the question. It is highly difficult for a computer to solve a mathematical equation by itself.

With the world becoming more advanced and more and more devices being conceived, ie. Smartphones, Smart car, and Smart house, along with a growing dependence on, them even on the level of the government, we need to protect our privacy and safety. It has been statistically shown that our safeguards against hackers and foreign threats is severely lacking. Still, this a worldwide problem, and with the technological revolution, people don’t know how to keep their information safe, so it is our job as part of the government to protect our citizens even from digital

Security is the most significant factor in authentication scheme. Our participants were enquired about how they often change their passwords and whether they have different passwords for different accounts, their answers were that they do not do that often; therefore, this would increase possibility of attacks. Here we briefly introduce some of the possible attacks which could break the Picture Pass Doodle system.

During this time Richard has showed himself as a promising young specialist and researcher. His major specialization is Applied Mathematics and Computer Science, but as an exception for academic achievements, Alex was allowed by our faculty to write his projects and degree thesis in the field of Cryptography under Computer Security and Applied Algebra Department.

The Internet is undoubtedly one of the most provocative sociological and psychological phenomena. Often the Internet says that it links all those fallen communicators who cannot cope in the real world. Socializing and surfing online space does not pass without leaving a trace. Each user provides information about themselves, sometimes as a condition to be able to access the required application, when consciously accedes to it, sometimes exchanging information with other members of the network, unaware that the network "remembers everything", that data remains deposited even when its removed profile. However, more often we are faced with data theft and identity by criminal hacker groups. Cyber security is a challenge that will have to be resolved

We live in a world today, in which technology moves at a very rapid pace. Many of these technological advances can be used to make our everyday lives easier and safer. One of these new technologies is Biometrics. Biometrics is the process of measuring a person’s physical properties. This would include measuring things like fingerprints, retinas, odor, vein structure on the back of the hand and many other things. Biometrics is a very important topic because it would create better security precautions for certain places that need to be secure. Biometrics will make our society safer by only allowing authorized people out of secure facilities and by keeping the unauthorized people out. Throughout the rest of this

I personally believe that one of the greatest challenges facing computing today is security. Nowadays, we have seen a tremendous growth in the usage of computer, whether it is for education, work, communication, science, or for any other reason. However, as our society becomes more computer oriented, the issue of security raises with it. Some people have made their first priority to use the Internet to hurt both individuals and/or organizations. These people have developed techniques to

An authentication method based on face recognition is designed for restricting access of incoming call for un-authorized entity. It will take the image of person (who wants to be registered as an authorized entity) during the registration process, once the registration is complete, it will monitor the entity while call receiving. Therefore the user can not receive the call unless the application will grant him as an authorized entity. For this purpose application has to monitor the call status and as the call status goes to incoming call, application has to restrict the receiving of call and take a photo of claimed entity by the same camera of mobile on which the call is coming. Once the image is captured, it will go through the

The concept of artificial intelligence was first labeled by a man named Alan Turing in 1950, he believed that the future would hold the possibility for man to communicate with computers and sustain a conversation (Atkinson, Solar 1). Although, we have reached the point where it is possible to hold a simple preprogrammed conversation with a computer and give them the ability to learn, there is still a long way to go in making computers fully artificially intelligent. Atkinson and Solar continue to describe some real world applications of artificial intelligence such as, “Data mining technologies, fraud detection, and industrial-strength optimization” (8). In these examples, forms of artificial intelligence like cognitive reasoning abilities are already being used making the demand for them higher.

Two-factor authentication (2FA) essentially adds another level of authentication for your log-ins. Instead of using only your username and password, you need

You have seen biometric technology in the films Mission: Impossible and Gattaca. The technology has also graced the covers of many weekly news magazines. But many people, even though the technology has been widely talked about for the last half decade, are still surprisingly unaware of what biometrics are and why the technology is so important for computer security and personal identification.

We are living in an information-driven world today that requires us to protect what and how we share this information. To access the guarded data or information we want to protect requires either a password or a pin. A password is a string or group of combined characters precise in length. Passwords and pins are suppositional, and more consideration is seriously required. They are the primary defense against intrusion. However, they can be easily captured and deciphered by cyber criminals. The security in this area is challenging due to the ineffectiveness of the creation of passwords and pins. Kirushnaamoni (2013) elicits that making logging in straightforward and convenient for users and trying to prevent password cracking is problematic. Cyber criminals will continue to persist and target the vulnerabilities in this area. Therefore, personally, financial, health and

Biometric technologies are getting better and finely tuned. The rate of false readings and errors has sharply fallen. However it still requires careful consideration and planning to implement a biometric identification system. They are most costly and complicated to implement as compared with other authentication systems. A proper evaluation of the system is important before purchasing any biometric system. A thorough risk analysis is necessary. In many cases biometrics may be overkill. Biometrics must be used if there is high level of risk involved. Customer acceptance is also important when logging on to company websites. Home users might not be ready to install biometrics on home computers for online banking.
