The effectiveness of intersection attack countermeasures for graphical passwords
No full textRecognition-based graphical passwords are one of several proposed alternatives to alphanumerical passwords for user authentication. However, there has been limited work on the security of such schemes. Often authors state a possible attack combined with a proposed countermeasure, but the efficacy of the counter measure is not always quantitatively examined. One possible attack which has been discussed without this examination is an intersection attack. If we can establish which countermeasures for this attack are effective, this will provide insight which will make it possible to select the appropriate countermeasure for the level of security required by a given system. Our approach involved creating a simulation of intersection attacks using each of five possible counter measures. The number of attacks which had to be performed before success for each approach was noted and compared to a control where no counter measure was implemented. Our results show that for three of the five countermeasures there was a significant increase in the number of attacks before success, one showed a significant decrease and the other did not show any statistical significance. We show that it is not decisive that using dummy screens when an incorrect image is selected will increase the number of attacks required. We also show that increasing the number of challenge screens reduces the number of attacks required before success as the number of challenge screens approaches the size of the passimage set. Our results allow one to make a more reliable choice of countermeasure to reduce intersection attacks
The Forgotten: NYC and School Segregation
No full textSchool segregation is an issue of the past and present. Generations of Black and Brown Americans have attended schools that were inadequate and unequal to their white counterparts. This inequity in access to quality education has caused issues with diversity in professional fields, like the medical and legal fields. The lack of diversity in these fields are the results of decades of school segregation due to the government’s failure to eradicate the dual system of education. Since the landmark case of Brown v. Board of Education, little progress has been made in providing Black and Brown children in metropolitan cities adequate or equal education to their white counterparts. New York City is just one example of how school segregation in metropolitan cities has decreased a minority’s chance at success in obtaining higher education and, as such, entering the professional work force. The diversity issues that are seen in these professional fields starts on the first day a child is enrolled into kindergarten. The chances of a Black or Brown child achieving success decreases with every year they continue to receive a separate and unequal education

Intertextuality and deja lu Salinger's and Dostoevsky's reminiscences in Wahei Tatematsu's A Sexual Apocalypse
No full textdeja luとは「すでに読んだことがあるという認識」である。テクストを読む「わたくし」が,作品Bのなかに作品Aに似た何かを発見するとき,「わたくし」が作品Aをかつて読んだことがあるというまさにそのことが事態の本質をなしている。つまり生きられた体験としての間テクスト性を観察するとき,その中核をなすのがdeja luという概念なのである。本論では立松和平『性的黙示録』にあらわれる夜汽車の場面が,サリンジャー『キャッチャー・イン・ザ・ライ』におけるホールデンとミセス・モロウとの出会いに酷似しているという発見を糸口に,deja luが間テクスト的読解へと展開していく過程を考察する。そのさい,ある種の理論家が唱える理念的な「読者」概念と生身の「わたくし」の経験の落差を記述する,という手法をとる。標準的なロシア文学研究者が『性的黙示録』のなかに認めるdeja luはドストエフスキーの諸作品の痕跡であると考えられるが,生身の「わたくし」が体験したdeja luはサリンジャー作品の上記の場面なのである。そしてサリンジャーと立松を対比させながら読むという営為もまた,両作家の作品の意義の解明に通じていることを示す。The aim of this study is to examine the relationship between intertextuality and deja lu. An intertextual reading consists of a recognition of something already read, i.e.deja lu. As Jonathan Culler puts it, an intertextual code is nothing more than this. The author of this study juxtaposes a scene from Wahei Tatematsu's magnum opus Seiteki Mokusiroku [A Sexual Apocalypse], which is yet to be translated into other languages, and one from J.D. Salinger's The Catcher in the Rye. In Tatematsu's novel, Koji, having finished an 8-year term in jail for murdering a woman, takes a night train and encounters an ugly middle-aged lady with a heavy northern Kanto dialect. Lying that he is a priest with a mysterious prophesy, he compells her to confess that she had her two babies aborted in her past. This scene somehow resembles Holden's encounter with his classmate's mother Mrs. Morrow on the night train bound for New York. Holden also lies that his name is Rudolph Schmidt and tells Mrs. Morrow that her son is a decent nice boy, which is not the case. When the author of this study came across the scene of Koji's encounter with an ugly lady, he experienced a strong feeling of deja lu, although details from both novels do not fully coincide. While an average student of Russian literature would find that Tatematsu's novel is full of Dostoevsky's reminiscences, the deja lu of the author of this study suggests that a comparison with The Catcher in the Rye is also of great use to elicit the traits of Tatematsu's novel. Thus, if one wishes to depict an intertextual reading as a lived experience, one has to juxtapose one's own deja lu and what Michael Rifaterre's "arch-reader" would find in the novel.E10KJ00005049269論文Articl
Towards a metric for recognition-based graphical password security
No full textRecognition-based graphical password (RBGP) schemes are not easily compared in terms of security. Current research uses many different measures which results in confusion as to whether RBGP schemes are secure against guessing and capture attacks. If it were possible to measure all RBGP schemes in a common way it would provide an easy comparison between them, allowing selection of the most secure design. This paper presents a discussion of potential attacks against recognition-based graphical password (RBGP) authentication schemes. As a result of this examination a preliminary measure of the security of a recognition-based scheme is presented. The security measure is a 4-tuple based on distractor selection, shoulder surfing,
intersection and replay attacks. It is aimed to be an initial proposal and is designed in a way which is extensible and adjustable as further research in the area develops. Finally, an example is provided by application to the PassFaces scheme
With the Same Motion: A Personal History of Belonging
No full textLillian Deja Snortland, an African American transracial adoptee, unearths fragments of matrilineal family-making myths buried amongst revelatory media and epistolary text, including postcards sent to her nineteen-year-old adoptive mother while sequestered in an unwed-mother’s home in Arizona. Roe v. Wade was argued Dec 13, 1971, approximately a year and two months after her adoptive mother would give birth and place her son up for adoption—a history Snortland discovers by accident as an adult.
In 1972, the National Association of Black Social Workers made the statement: “We affirm the inviolable position of Black children in Black families where they belong”. Snortland was part of a closed adoption in 1996, in Kansas City in the aftermath of reconstruction, redlining, and oppression, when racial assimilation was being equated with erasure. Her successful adoption by a white Irish Catholic family in Eugene, Oregon adds nuance to the concept of ideal restoration for the next generations of Black children.
In the wake of an estimated 50 million transracial adoptions in 2010 in the United States, policies around freedom of information and conversations have changed drastically to incorporate new understandings of the harmful psychology of difference for adoptees, the consequences of familial separations, and an increased emphasis on mental health and multicultural belonging. Snortland’s story traces questions posed by sociologists, social workers, and mental health advocates, as well as those interested in research like The Adoption History Project through the Department of History at the University of Oregon.
With the Same Motion explores cross-generational intimacy, interracial lineage, and the liberatory importance of choice as the author purposefully reshapes familial boundaries. The manuscript follows an adoptee researching her adoptive family, rather than her biological one, to understand how choice is a powerful familial tether, and complicate the idea that motherhood, sisterhood, or daughterhood should subsume a woman’s autonomy
