For more secure authentication, a 3-D password is proposed that combines multiple authentication factors into a 3D virtual environment. The user navigates and interacts with virtual objects to construct their password. This multi-factor approach includes textual passwords, graphical passwords, and biometrics within a 3D space. The environment design and included objects determine the large key space size, making passwords difficult to crack compared to traditional methods. However, 3D passwords also require more sophisticated technology and programming.
Users nowadays are provided with major password stereotypes such as textual passwords, biometric scanning, tokens or cards (such as an ATM) etc. Mostly textual passwords follow an encryption algorithm as mentioned aboveBiometric scanning is your "natural" signature and Cards or Tokens prove your validity. But some people hate the fact to carry around their cards, some refuse to undergo strong IR exposure to their retinas(Biometric scanning). Mostly textual passwords, nowadays, are kept very simple say a word from the dictionary or their pet names, girlfriends etc. Years back Klein performed such tests and he could crack 10-15 passwords per day. Now with the technology change, fast processors and many tools on the Internet this has become a Child's Play.

The 3-D password is a multifactor authentication scheme that combines these various authentication schemes into a single 3-D virtual environment. The virtual environment can contain any existing authentication scheme or even any upcoming authentication schemes by adding it as a response to actions performed on an object. Therefore, the resulted password space becomes very large compared to any existing authentication schemes.

Pattern Recognition in Multiple Bike sharing Systems for comparabilityAthiq Ahamed
Bikesharing is a sustainable short-term bicycle rental service that enhances the urban public transport options. The major issue for the providers of bikesharing is the disproportions in the distribution of bikes. Ensuring reliable provisioning of bikes and docks at the bike stations is significant for the bikesharing system. This thesis presents a novel comparability model that provisions to improve the bikesharing systems design. The comparability model was developed by analyzing widespread operational data from multiple bikesharing systems to derive bike activity patterns. Thedatausedforanalysisisrecordedautomaticallybythebikesharing systems. Hence, advanced Geo BI and Data Mining techniques are used to clean the data and gain insights of the bike activity patterns. These techniques gained insights from the complex bike activity pattern from multiple bikesharing systems. The insights from the patterns lead to a better understanding of complex bikesharing systems. The patterns are then proved interesting, with several hypotheses. As a result, multiple bikesharing systems are proved comparable, that lead to the development of a novel comparability model (NyDc). The NyDc model helps in determining the trip purpose using spatio-temporal distributions of bike trips. NyDc, reveals the disproportion in the distribution of bikes in multiple systems and helps in understanding the systems better. NyDC could serve as a benchmark for comparability analysis. NyDc consists of useful metadata that could be utilized for future comparability research. Hence, NyDc could be used for improving or enhancing the design, planning, and management of the existing bikesharing systems or a new bikesharing system in another city.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. Basic Identification Methods of password
Possession Knowledge
(“something I have”) (“something I know”)
•Keys •Password
•Passport •PIN
•Smart Card
Biometrics Recognition
(“something I am”) (“something I recognise”)
•Face • Graphical
•Fingerprint Password
•Iris
3. PASSWORD
• It is basically a encryption algorithm
• Usually 8-15 characters or slightly more than that
• Can be meaningful words from dictionary, pet names,
name of friends etc
• Easy to break and vulnerable to Brute force attack
4. PASSPHRASE
• Enhanced version of password
• Combination of words or simply a collection of passwords
in proper sequence
• Length is about 30 – 50 characters or more than that also
• Creates ambiguity to remember if there is no proper
sequence
5. GRAPHICAL PASSWORDS
• Based on the idea that users can recall and recognize
pictures better than words.
• Require a long time to be performed
• Have a password space that is less than or equal to the
textual password space
• Vulnerable to shoulder surfing attacks
6. BIOMETRICS
• Automatethe identification or verification of an individual
based on human characteristics or body organs.
• Physiological: Face, fingerprint, iris
• Behavioral: Hand-written signature, voice

• (10, 24, 91) Action = Close the office door;
• (4, 34, 18) Action = Typing, “F”;
• (4, 34, 18) Action = Typing, “A”;
• (4, 34, 18) Action = Typing, “L”;
• (4, 34, 18) Action = Typing, “C”;
• (4, 34, 18) Action = Typing, “O”;
• (4, 34, 18) Action = Typing, “N”;
• (10, 24, 80) Action = Pick up the pen;

schemes
•It is the task of the system administrator to design the environment and
to select the appropriate object that reflects the protected system
requirements
• Designing a simple and easy to use 3D virtual environment is a factor
that leads to a higher user acceptability of a 3D password system.
