...However, they are mostly vulnerable to shouldersurfing. In this paper, we propose a Scalable ShoulderSurfing Resistant Textual-Graphical Password Authentication Scheme (S3PAS). S3PAS seamlessly integrates both graphical and textual password schemes and provides nearly perfect resistant to shoulder-surfing, hidden-camera and spyware attacks. It can replace or coexist with conventional textual password systems without changing existing user password profiles. Moreover, it is immune to brute-force attacks through dynamic and volatile session passwords. S3PAS shows significant potential bridging the gap between conventional textual password and graphical password. Further enhancements of S3PAS scheme are proposed and briefly discussed. Theoretical analysis of the security level using S3PAS is also investigated. is vulnerable to shoulder-surfing, hidden-camera and spyware attacks. Graphical password schemes have been proposed as a possible alternative to text-based schemes, motivated partially by the fact that humans can remember pictures better than text [8]. In addition, the possible password space of a graphical password scheme may exceed that of textbased schemes and thus presumably offer higher level...

...Medical Applications of EEG Wave Classification Wanli Min and Gang Luo Medical Background D id you know your brain continuously emits electric waves, even while you sleep? Based on a sample of wave measurements, physicians specializing in sleep medicine can use statistical tools to classify your sleep pattern as normal or problematic. Brain-computer interfaces (BCIs) now being developed can classify a disabled person’s thinking based on wave measurements and automatically execute necessary instructions. This type of research is exciting, but conducting it requires knowledge of medicine, biology, statistics, physics, and computer science. Electroencephalogram (EEG) is the recording of electrical activity through electrode sensors placed on the scalp. The electricity is recorded as waves that can be classified as normal or abnormal. Measuring EEG signals is not an intrusive procedure; it causes no pain and has been used routinely for several decades. Different types of normal waves can indicate various states or activity levels. Abnormal waves can indicate medical problems. Two important applications of EEG wave classification are diagnosis of sleep disorders and construction of BCIs to assist disabled people with daily living tasks. Sleep, which takes up roughly one-third of a person’s life, is indispensable for health and well-being. Nevertheless, onethird of Americans suffer from a sleep problem. For example, one in five American adults has some...

...Performance analysis of Substitution Cipher Based Cryptographic Algorithm Mihir Sanghavi 11MCA48, Student, MCA Programme, Institute of Technology, Nirma University, Ahmadabad Email: 11MCA48@nirmauni.ac.in Abstract Cryptography is the study of Encryption techniques related to aspects of information security, such as confidentially or privacy, data integrity and entity authentication. Today’s world, for secure data transmission via Internet or any public network, there is no alternative to cryptography. The role of Cryptography is most important in the field of network security. The main goal of cryptography is Confidentiality, Integrity, Authentication, Non repudiation. Cryptography is widely used by governmental and intelligence agencies around the world to safe transmission of any format of messages online or offline. In cryptography, a substitution cipher is a method of encryption by which units of plaintext are replaced with cipher text, according to a regular system; the "units" may be single letters, pairs of letters, triplets of letters, mixtures of the above, and so forth. The receiver deciphers the text by performing an inverse substitution. Caesar cipher is an example of substitution cipher method. In this paper substitution cipher based cryptography algorithms are compared and performance is evaluated. Keywords Cryptography, substitution cipher, cryptanalysis, Caesar cipher, monoalphabetic cipher and Polyalphabetic cipher. Introduction A substitution...

...Sams Teach Yourself C in 24 Hours Previous | Table of Contents | Next Hour 1 - Getting Started A journey of a thousand miles is started by taking the first step. —Chinese proverb High thoughts must have high language. —Aristophanes Welcome to Teach Yourself C in 24 Hours. In this first lesson you'll learn the following: What C is Why you need to learn C The ANSI standard Hardware and software required in order to run the C program What Is C? C is a programming language. The C language was first developed in 1972 by Dennis Ritchie at AT&T Bell Labs. Ritchie called his newly developed language C simply because there was a B programming language already. (As a matter of fact, the B language led to the development of C.) C is a high-level programming language. In fact, C is one of the most popular general-purpose programming languages. In the computer world, the further a programming language is from the computer architecture, the higher the language's level. You can imagine that the lowest-level languages are machine languages that computers understand directly. The high-level programming languages, on the other hand, are closer to our human languages. (See Figure 1.1.) Figure 1.1. The language spectrum. High-level programming languages, including C, have the following advantages: Readability: Programs are easy to read. Maintainability: Programs are easy to maintain. Portability: Programs are easy to port across different computer platforms. The...

Better file management systems will help to eliminate ambiguous file names, mysterious file contents, unknown creation dates and odd filing locations can make finding computer files a pain. 3. What are some factors you should consider when deciding whether to use Access or Excel to manage data? * Access is better for storage, Excel for analysis * Access copes better with large quantities of data * Excel is better at numbers than text * Access is better at data entry * Access copes better with sharing data * Access allows users to connect to several different data sources, and edit the data therein * Excel is better at what-if analysis * Excel is better at interactive analysis using tools such as PivotTable reports * Excel is better at conveying information visually * Not everyone has Access, not everyone knows how to use it 4. Describe the power of a relational database. Relational databases use a set of tables to store the data and a set of relationships to link the tables together. It creates a more logical representation of the data and allows faster access and powerful manipulations of the data stored in the database. However searching, updating or generating reports based on data in flat files are really harder...

This text talks about the great virtue of hard work possessed by Delia, who continually “breaks her back” to make ends meet for her family. This text associates Delia’s character with the symbol of virtue and purity which is evident in her religious commitment to church. The text also describes Delia’s struggle and pain inflicted by her husband Sykes and likens this to the universal motif of the struggle between “good and evil” where good always triumphs over evil. In my opinion this source correctly categorizes...

...ac.uk doi: 10.1111/jasp.12148 Abstract Video game developments allow players to design their own personalized avatars. Previous research has shown that this capability increases levels of aggression within socially acceptable forms of violence. Using the general aggression model (GAM), the current study examined the effect of avatar personalization on behavioral aggression within a violent video game. Participants who played a violent video game and designed their own avatars were significantly more aggressive than those who played the same violent video game with a generic avatar, and were also more aggressive than those who played the nonviolent video game, regardless of whether or not they designed their own personalized characters. Limitations and directions for future research are discussed. Games present opportunities to behave in ways that are exhilaratingly wicked and dangerous—out of reach in real life. Freedom from consequences, and hence a feeling of escaping, is appreciated most keenly where there is violence. (British Board of Film Classification [BBFC], 2010) Research and anecdotal evidence supports the notion that playing violent video games increases levels of cognitive, affective, and behavioral aggression and decreases levels of prosocial behavior (Anderson & Carnagey, 2009; Anderson & Dill, 2000; Carnagey & Anderson, 2004; Greitemeyer &...

...RENA FANDRICH UNIVERSITY OF CALIFORNIA, SANTA BARBARA FEBRUARY 2003 ACKNOWLEDGMENTS The authors wish to convey their sincere appreciation to a number of individuals who have played important roles in supporting and facilitating this research. At UCSB, Charles Mullin directed the videotaping effort that captured over 1,000 programs for analysis with diligence, dedication, and careful precision, as he has done consistently over the years in his work on this project. Emma Rollin generously assisted in this effort, assuming primary responsibility for several of the channels studied. The staff at UCSB’s Institute for Social, Behavioral, and Economic Research accomplished all of the financial aspects of the study helpfully and expertly. Tim Schmidt, Jan Jacobson, Jan Holtzclaw, Monica Koegler-Blaha, and Nicole DuBois all contributed to the success of this study with their “can do” approach to the many challenges posed by administrative bureaucracies. At the Kaiser Family Foundation, Vicky Rideout has been an invaluable partner since the outset of this ongoing project tracking sexual messages on television. Her vision of a benchmark analysis that could be repeated over time to track industry trends seemed incredibly ambitious when we first started our work. Now that this vision has been genuinely realized with our third report, it is impressive to see the accumulated knowledge that has resulted, and inspiring to observe its application in policy debates and social responsibility...

...Headnote This two-part exploratory study utilized a social cognitive theory framework in documenting gender portrayals in teen movies and investigating the influence of exposure to these images on gender-based beliefs about friendships, social aggression, and roles of women in society. First, a content analysis of gender portrayals in teen movies was conducted, revealing that female characters are more likely to be portrayed as socially aggressive than male characters. Second, college students were surveyed about their teen movie-viewing habits, gender-related beliefs, and attitudes. Findings suggest that viewing teen movies is associated with negative stereotypes about female friendships and gender roles. Research examining the effects of media exposure demonstrates that media consumption has a measurable influence on people's perceptions of the real world, and, regardless of the accuracy of these perceptions, they are used to help guide subsequent attitudes, judgments, and actions. For example, these results have been yielded for viewing media representations of race,1 the mentally ill,2 and the elderly.3 Past research additionally indicates that watching televised gender portrayals has an effect on individuals' real-world gender-based attitudes, beliefs, and behaviors.4 Based on this research, and the tenets of social cognitive theory, it would be expected that consumption of teen movies would have an analogous influence on audience members' gender-based attitudes and beliefs...

...'): changeChannelTo(143) The snippet calls the function predefined by us to change the channel specified. The app accepts the voice input. The sentence is first morphologically analyzed. The purpose of this stage in language processing is to break strings of language input into sets of tokens corresponding to discrete words, sub-words and punctuation forms. The tokens derived may contain Inflective, derivative and compound sense. They are split into sub-tokens. For example “switch” is obtained from the word “switching”. The output from the morphological processing phase is a string of tokens which can then be used for lexicon lookup. The next stage would be the syntactic and semantic analysis. The purpose of syntax analysis is to check whether a string of words is well formed or not and to break it up into a structure that shows the syntactic relationships between the different words. A syntactic analyser (or parser) does this using a dictionary of word definitions (the lexicon) and a set of syntax rules (the grammar). For example, for the sentence “Turn the television on”, the syntactic and semantic structure can be constructed using Grammar lexicon combination as in Figure 2. The next stage would be semantics. Here the sentence is analysed for its basic meaning. For example, the words “start” and “begin” is translated as “on” which is predefined. The Pragmatics stage involves specifying where the action has to be carried...
