Abstract—Because of the drawbacks of the text based authentication systems, graphical passwords are the most preferable type of authentication mechanism , where users click on images for the authentication purpose. The main goal of an authentication system is to help users for selecting the better password. If the password is created by the user , then it is easy to guess by an attacker and if the passwords is assigned by the system, then it is difficult for the user to memorize. So modern researches conclude that graphical passwords are most preferable authentication system. A graphical password uses images or representation of images as passwords. Human brain can easily recollect the graphical image secret word compare to Text secret word.. …show more content…
In early days, text based passwords are used for authentication . Text based password authentication uses alphanumeric letters for creating passwords . Here, users always creates password which is easy to remember but these passwords are easy for attackers to break. For provide more security, users use strong system assigned passwords which will be difficult for users to remember. Biometric and tokens [9] are used as an alternative to text based passwords. But it also has its own drawbacks such as it requires extra hardware for its implementation, so such methods are costly. As an alternative to all these methods, graphical passwords are used because psychological studies shows that human brain can recognize images better than the text.Graphical password uses images or representation of an image as a …show more content…
Users can shuffle the random characters until they find memorable password.
Basically PTP is a user-chosen text secret code system which helps user to build their password more secure.
IV.PROPOSED SYSTEM
The proposed system is based on click based graphical password system that not only helps the user for password selection but also encourages the user to select more random distributed password.
In this system, user clicks on a sequence of five images. At the login time images appear as per the random sequence. In the registration phase, user selects 5 images from the image pool.
Based on the image selection server generate the signature during registration. While users coming to login phase, select images from the image pool based on image selected by registration phase and then the server generate the new signature based on this selected images. If both the signatures are same, then a Pixel based CAPTCHA and OTP are generated and sent to the user’s mail by server. Otherwise abort the user. This proposed system provides three-way authentication and also provides higher security than
How would you feel if everything you did on the internet, every text you sent, and every call you made was seen by someone? That is what the NSA is doing right now. According to Wikipedia, the National Security Agency is a national-level intelligence agency of the United States of Defense, under the authority of the Director of National Intelligence.[1] They have been a controversial topic since the 1970s when it was revealed that they had been wiretapping Americans’ telephones. Their surveillance has only grown since then, even though most Americans disagree with it. [2] The NSA’s domestic surveillance is unconstitutional, ineffective, and a violation of privacy that needs to be stopped.
The aftereffects of the September 11, 2001 attacks led to Congress passing sweeping legislation to improve the United States’ counterterrorism efforts. An example of a policy passed was Domestic Surveillance, which is the act of the government spying on citizens. This is an important issue because many people believe that Domestic Surveillance is unconstitutional and an invasion of privacy, while others believe that the government should do whatever is possible in order to keep the citizens safe. One act of Domestic Surveillance, the tracking of our phone calls, is constitutional because it helps fight terrorism, warns us against potential threats, and gives US citizens a feeling of security.
The NSA is a U.S. intelligence agency responsible for providing the government with information on inner and foreign affairs, particularly for the prevention of terrorism and crime. The NSA maintains several database networks in which they receive private information on American citizens. The agency has access to phone calls, emails, photos, recordings, and backgrounds of practically all people residing in the United States. Started in 1952 by President Harry Truman, the NSA is tasked with the global monitoring and surveillance of targeted individuals in American territory. As part of the growing practice of mass surveillance in the United States, the agency collects and stores all phone records of all American citizens. People argue that this collected information is very intrusive, and the NSA may find something personal that someone may not have wanted anyone to know. While this intrusion's main purpose is to avoid events of terrorism, recent information leaks by Edward Snowden, a former NSA contractor, show that the agency may actually be infringing upon the rights of the American citizen. Whether people like it or not, it seems that the NSA will continue to spy on the people of the United States in an attempt to avert acts of terrorism. Although there are many pros and cons to this surveillance of American citizens, the agency is ultimately just doing its job to protect the lives of the people. Unless a person is actually planning on committing a major crime, there is no real reason for citizens to worry about the NSA and it's invasion of our privacy. The agency is not out to look for embarrassing information about its citizens, rather, only searches for and analyzes information which may lead to the identification of a targe...
We all have heard the quote “Life, Liberty, Land, and the Pursuit to Happiness” and that is the promise of a life here in America. As Americans we pride ourselves on these freedoms that allow us to live everyday. We are one of the only countries that have this promise and it is what draws people from all of over the world to come here. Our founding fathers of the United States of America wrote these words, having no idea the impact that they would have for the rest of this countries history. Those words were the foundation for government, and it wasn’t perfect at first but slowly it matured into what we have today, strong and powerful. To other nations America is seen as the World Power, and a somewhat perfect nation to live in. Unfortunately corruption, scandals and controversies have tainted our once golden glow, and other nations are weary of watching their steps. One of the most controversial elements to our government is the NSA. Hidden in the shadows from American and global knowledge is what the NSA is actually doing and watching out for. Only very recently has the NSA been ripped from the shadows and brought to light what exactly is going on inside those walls. They are “spying” on not only America’s personal data, but foreign leaders as well. The NSA says it’s for the safety for everyone against terrorism and attacks. However, it has gone way to far and violates a constitutional right, privacy. The NSA has overstepped their boundaries, and spying doesn’t seem to make a difference in safety.
Whether to arm the police is a contentious subject. While some supporters maintain that unarmed police are unable to protect law-abiding citizens, opponents reject this notion on the grounds that it could lead to a surge of violence in society.
Cameras go way back to the year 1879, and have advanced greatly throughout the years. They used to be huge and bulky with all kinds of attachments and stands. Now they are so small and thin that they are put in everyday items that we use, for instance, cell phones and laptops. Backs then cameras were less than $40 and they were made with glass that was 6.5 by 8.5 inches thick (Patti). Now in this time of age, cameras can go from a few hundred bucks to thousands of dollars depending on the camera, and they are much smaller with clearer pictures now. In 1912 Kodak came out with the Vest Pocket camera, which sold for only six dollars. It had a glass lens of 2 1/4 by 3 1/4 inches thick, which is much
Biometric and encryption sounds are not too fresh, for most users, any of each technology alone is not enough to make you feel excitement. However, If we develop a new study or a new technology, which combine the biometrics and encryption. We can find that the technology combining these two techniques are very amazing.
Biometrics is described as the use of human physical features to verify identity and has been in use since the beginning of recorded history. Only recently, biometrics has been used in today’s high-tech society for the prevention of identity theft. In this paper, we will be understanding biometrics, exploring the history of biometrics, examples of today’s current technology and where biometrics are expected to go in the future.
Is it public knowledge that the Secret Service protects most of the important political figures? Is it public knowledge that the Secret Service works many of the secret missions that the army cannot? The Secret Service makes a commendable amount of compensation ("Secret Service Agent Salaries"). The service also has responsibilities among the strongest ("The American Presidency"). The qualifications for the Secret Service include many tests both mentally and physically (Lawi.us). The Secret Service has large compensation, strong responsibilities, and many qualifications. The Secret Service is one of the hardest but well paying jobs.
Biometric is a device that can recognize someone 's unique physical trait, for example fingerprints, eyeball, face, or voice and it uses them as a means of authentication to gain access to something. Hackers can never gain access to someone’s privacy who uses biometric as a means of gaining access to his/her privacy. Biometric is the surest thing that can never be compromised, if it’s being done correctly because it is attached to the natural inbuilt quality of the user. In order for hackers to use it, they must go through an extra ordinary mile which could lead to other crimes like kidnapping or
A security certificate is like a special deportation warrant in which the Canadian government can deport any “non-Canadians” who they feel are a threat to Canada and its citizens. An example of this would be anyone that the Canadian government feels is involved with a terrorist group or organization will be deported using a security certificate. Some pros to the security certificate are it will help the Canadian government better protect Canada by deporting anyone who poses a serious threat to Canada, and its citizens. Another pro is it limited in use as security certificates have only been used 27 times since 1991, meaning the powers of the security certificates have not been abused as of yet. It is somewhat fair to the person a security certificate
There has always been surveillance of the general public conducted by the United States government, the usual justifications being upholding the security of the nation , weeding out those who intend to bring harm to the nation, and more. But the methods for acquiring such information on citizens of the united states were not very sophisticated many years ago so the impact of government surveillance was not as great. As a result of many technological advancements today the methods for acquiring personal information - phone metadata, internet history and more - have become much simpler and sophisticated. Many times, the information acquired from different individuals is done so without their consent or knowledge. The current surveillance of people
The term biometrics is commonly known as the field of development of statistical and mathematical methods applicable to data analysis problems in the biological sciences. Though, even more recently it has taken on a whole new definition. Biometrics is an amazing new topic referring to “the emerging field of technology devoted to the identification of individuals using biological traits, based on retinal or iris scanning, fingerprints, or face recognition”. Biometrics has already begun using applications that range from attendance tracking with a time clock to security checkpoints with a large volume of people. The growing field of biometrics has really been put on the map by two things, the technological advances made within the last 20 years, and the growing risk of security and terrorism among people all over the world. In this paper I will focus on: the growing field of biometrics, why it is important to our future, how the United States government has played a role in its development and use, the risks involved, the implications on public privacy, and further recommendations received from all over the science and technology field.
When the entire body of knowledge concerning passwords is evaluated a few things become abundantly clear. First, passwords are going to be around for some time yet. There simply are no present alternatives that are cost competitive with passwords or that users can adopt in a successful manner. While it is certainly a noble effort to explore replacements for passwords, we cannot refuse to acknowledge their continued existence in the foreseeable future.
Biometrics can be used as a method of identification for accessing a computer, room, or anything where identity needs to be provided to access information or equipment. Some people resist biometrics because of the concerns in which their privacy will be invaded or they think technology is getting too intrusive on people personal lives. Biometrics is not flawless and does have some privacy related issues. There are mechanism that can be put in place which could mitigate these problems and concerns. Some biometrics may not meet due to undue resistance from potential users and may be recommended to the manager to use password-based access controls instead.
