Since the key is user-specific, multiple templates for the same user biometric can be generated by using different keys (allowing diversity). Also in case a template is compromised, it is easy to revoke the compromised template and replace it with a new one generated by using a different user-specific key (allowing revocability). Key generating biometric cryptosystem Advantages (1) Since it is hard to recover the original biometric template even when the key is compromised, this scheme provides better security than the salting approach. (2) Diversity and revocability can be achieved by using application-specific and user-specific transformation functions, respectively. 1 18 3 4 Information Systems Security Advantages This approach is tolerant to intrauser variations in biometric data and this tolerance is determined by the error correcting capability of the associated codeword. Biometric Template Security Salting 16 Limitations The main drawback of this approach is the trade off between discriminability and noninvertibility of the transformation function. BIOMETRIC SYSTEM VULNERABILITY Ratha et al proposed and analyzed three noninvertible transforms for generating cancelable fingerprint emplates. The three transformation functions are cartesian, polar and functional. Limitations It is difficult to generate key with high stability and entropy. one-way function Limitations Matching has to be done using error correction schemes and this precludes the use of sophisticated matchers developed specifically for matching the original biometric template. This can possibly lead to a reduction in the matching accuracy. In general, biometric cryptosystems are not designed to provide diversity and revocability. However, attempts are being made to introduce these two properties into biometric cryptosystems mainly by using them in conjunction with other approaches such as salting. The helper data needs to be carefully designed; it is based on the specific biometric features to be used and the nature of associated intrauser variations.

Sincematching takes place in the transformed domain, the salting mechanism needs to be designed in such a way that the recognition performance does not degrade, especially in the presence of large intrauser variations.

Transcript: Assessing the Maritime Students’ Perceptions and Preparedness of Coastal Resilience: A Descriptive Correlational Study BSMT SII-BRAVO (GROUP1) OBJECTIVES: The sole purpose of the descriptive correlational study is to investigate fundamental research inquiries through a comprehensive assessment of the level of awareness, perception, and readiness among maritime students about coastal resilience. The chapter presents the findings from the data gathered. The chapter is organized into themes that go along with the sub-themes obtained through thematic analysis which is also derived from the research questions. The result is hereby integrated with the information gathered from the interviews. To examine the extent of maritime students' awareness of coastal resilience and its importance. To investigate the opinions of maritime students regarding coastal hazards and theirpossible impact on many elements of maritime activity. To evaluate the preparedness of maritime students in implementing coastal resiliencemethods within their field focuses on assessing their readiness. To recommend practical suggestions for enhancing the education and training ofmaritime students within the framework of coastal resilience and monitoring systems. CONCLUSION: 1. The extent of maritime students' awareness of coastal resilience and its importance is very pivotal in achieving success. 2. The opinions of maritime students regarding coastal hazards and their possible impact on many elements of maritime activity differs from their educational backgrounds, views, opinions, and perspectives that can be seen from positive and negative statements. 3. The preparedness of maritime students in implementing coastal resilience methods within their field focuses on assessing their readiness. 4. The recommended practical suggestions for enhancing the education and training of maritime students within the framework of coastal resilience and monitoring systems will be a great leap towards total quality achievement. RECOMMENDATIONS: 1. School administrators may support the development of practical suggestions for enhancing the education and training of maritime students within the framework of coastal resilience and monitoring systems. 2. Strengthen or maintain development programs for maritime students that nurture the development of their personal life and professional role. 3. The education and training of maritime students within the framework of coastal resilience and monitoring systems may be reviewed, refined, and later used to guide researchers. 4. Future researchers may use this study as a reference for further study on variables that were not explored in this study. This descriptive correlational study evaluated maritime students' views of and readiness for coastal resilience in order to prevent problems in the near future. The purpose of this study was to determine how good the maritime students were in understanding the ideas of coastal resilience and how equipped they were to handle issues that may arise along the coast. The findings showed that most of the participants had awareness and comprehension about the topic. While most of them also agreed that it is still dangerous for reducing the effects of climate change and natural disasters. Findings also revealed that there were differences in their level of practical readiness to deal with these problems since they differ from aspects as observed in their demographic profiles. This study which is a qualitative research provided themes and subthemes, through thematic analysis of the concept the focuses on the information and solicited opinions of the female participants. Findings from the data analysis have been organized by themes, with each theme referencing several sub themes and codes from the analysis

Transcript: Wisdom does not flow like water Plato’s Critique of Pederasty Pederasty Background Symposium Pederasty My Project Pausanias' Speech Pausanias' Speech Two Aphrodites Uranian Heavenly Pandemos Common Text Text Pictures Pictures "Here, Socrates, lie down alongside me, so that by my touching you, I too may enjoy the piece of wisdom that just occurred to you while you were in the porch. It is plain that you found it and have it, for otherwise you would not have come away beforehand." Agathon and Socrates “It would be a good thing, Agathon, if wisdom were the sort of thing that flows from the fuller of us into the emptier, just by our touching one another, as the water in wine cups flows through a wool thread from the fuller to the emptier. For if wisdom too is like that, then I set a high price on my being placed alongside you, for I believe I shall be filled from you with much fair wisdom. My own may turn out to be a sorry sort of wisdom, or disputable like a dream; but your own is brilliant and capable of much development, since it has flashed out so intensely from you while you are young; and yesterday it became conspicuous among more than thirty thousand Greek witnesses." "You are outrageous, Socrates," Agathon said. "A little later you and I will go to court about our wisdom, with Dionysus as judge, but now first attend to dinner." how water flows Principle at play When they do engage in a contest about love Timeline YEAR Alcibiades' Speech Socrates, he claims, is like “those silenuses that sit in the shops of herm sculptors, the ones that craftsman make holding reed pipes or flutes; and if they are split in two and opened up they show they have images of gods within.” (215b) Alcibiades' Speech You, in my opinion,' I said, 'have proved to be the only deserving lover of mine; and it seems to me that you hesitate to mention it to me. Now I am in this state: I believe it is very foolish not to gratify you in this or anything else of mine—my wealth or my friends—that you need; for nothing is more important to d me than that I become the best possible; and I believe that, as far as I am concerned, there is no one more competent than you to be a fellow helper to me in this. So I should be far more ashamed before men of good sense for not gratifying a man like you than I should be before the many and senseless for gratifying you.' Seduction Scene 'Really, my dear Alcibiades, you're no sucker if what you say about me is really true and there is some power in me e through which you could become better. You must see, you know, an impossible beauty in me, a beauty very different from the fairness of form in yourself. So if, in observing my beauty, you are trying to get a share in it and to exchange beauty for beauty, you are intending to get far the better deal. For you are trying to acquire the truth of beautiful things in exchange for the seeming and opinion of beautiful things; and you really have in mind to exchange "gold for bronze." But blessed one do consider better: Without your being aware of it—I may be nothing. Thought, you know, begins to have keen eyesight when the sight of the eyes starts to decline from its peak; and you are still far from that.' Conclusion conclusion If Socrates were to have sex with Alcibiades, he would perpetuate: 1) the idea that people can make each other wise. impact: prevent Alcibiades from realizing his ignorance about wisdom 2) Alcibiades belief that his physical attractiveness is the most important thing about him impact: the belief could harm Alcibiades as he begins to decline from his physical peak, when “Thought begins to have keen eyesight.” (219a) 3) Socrates would be no better than the sophists who cannot acknowledge the ways in which they are ignorant, and thus, risk self-deception. Advantages Advantages to my account: -Fits with the well-known picture of a Socrates who: 1) proclaims his own ignorance. 2) critiques the Sophists for i. both not acknowledging what they do not know ii. exchanging money for wisdom -Makes explicit the way Plato critiques the customs of his time -Throws into question a vision of Socrates as someone who consistently denies bodily urges -Makes clear that the container model is supposed to function in opposition to the image of pregnancy and birth. Accounts of “Plato’s Appropriation of Reproduction” run these two images together.
