Aadhaar: It's time to encrypt all biometric data with password

By
All biometric data should be encrypted. During authentication, the user needs to provide both aadhar number and password.

So only the user can decrypt and access the biometric data. Biometrics of the little finger can be kept in the unencrypted form, to remove duplicates.

In case you forget the password:
One has to submit the aadhaar number and little finger biometrics to obtain another.
The ciphertext of aadhaar number should be replaced with new ciphertext (obtained from new password)

In case you lost both (Password and Aadhaar Number):
The person must come under scrutiny and old aadhaar number should be removed by using his/her little finger, and new aadhaar number can be given.

To change the password:
Enter the old password and aadhaar number, match the ciphertext with your fingerprint and then replace the ciphertext with new password.

All the steps should be done in aadhaar center.

The python code:

from Crypto.Cipher import AES obj = AES.new('Aadhaar No:1234567891012', AE…

Universal Basic Income and Education: A beginning to a continued resilient human ecosystem

By

Universal Basic Income is a welfare regime in which all citizens (or permanent residents) of a country receive a regular, liveable and unconditional sum of money, from the government.

The central claim that UBI tries to solve is the end of poverty and financial insecurity by the indsicriminatory supply of free money which can be exchanged to buy your basic need requirements.

But the problem lies with execution and design that nullify the damaging possibilities speculated by the critics.

Speculation:
It disincentivizes people to work, so can create an adverse condition for wealth creation.

A proposed elaborative solution:

Morally, the basic required need for survival such as food, clothing, shelter are not incentives. Its a fundamental right of the people. But biologically, these are the incentives to pacify our hunger or appetite.
Food, clothing, shelter are basic needs for survival, but we need lot more for thriving. One of the essentials to thrive is education that nourishes our memor…

Explaining true experiment to a 13-year-old

Let's start with a Twitter Joke:
Conversation over breakfast.
ME: Whoa, you lost another tooth?
A: Yes!
ME: Why didn't you tell me?
A: I'm conducting an experiment. If I lose a tooth and don't tell anyone, will the tooth fairy still come? If not, then I know the tooth fairy isn't real.
ME: ...
HUSBAND: 😮

A small introduction to true experiments True experiments involve changing one variable and then measuring another. A variable is any factor, trait, or condition that can exist in differing amounts or types.

The two main variables in an experiment are the independent and dependent variable.

An independent variable is a variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable.

A dependent variable is a variable being tested and measured in a scientific experiment.

Independent variable: Cause
Dependent variable: Effect
The researcher is looking for the possible effect on the dependent variable that might be caused by c…

What happens when you limit the voicing of these two important words?
1) Nescience : (Ignorance is a lack of knowledge)
Our eyes and senses are limited by many ways. We are adapted to view the world perfectly only at a particular zooming level. The world becomes blurred when we increase or decrease the zooming level. We can't know what is happening in another country just by our senses. Increasing and decreasing the zooming level requires indirect measurements that are tedious and sophisticated. You need to learn the outcomes of the research, and techniques to make measurements by bringing it down to texts and tools that are compatible with our zooming level.
Without sharing these texts, using and adapting it, our knowledge will be limited to our zooming level and will…

Higher education must immediately stop obsolete blackboard teaching. Higher ed requires mentor and collaboration.


What is obsolete blackboard teaching?
[Lecturing is the] best way to get information from teacher’s notebook (mouth)
to student’s notebook without touching the student’s mind.                                                                                         — George Leonard Patterns for bad practices of teaching, what is done in higher education, even best colleges.

So, how this can be solved?
This is how colleges must run when there is the shortage of skilled teachers:
1) Give students compilation of pedagogically right content (such as videos, MOOCs, books, magazines etc.)

If all scientific discovery relies on peer review for validation, why not assessment be done through peer review?

All scientific discovery relies on peer review for validation,
Why not the assessment of schools and colleges be done through peer review?




Peer Review definition:
evaluation of scientific, academic, or professional work by others working in the same field.

In case of open peer review, the reviewer reports are published which can again go through auditing.

Benefits of open peer review:
1) Feedback to the students
After a test, feedback to the student becomes a crucial part of their learning. Feedback can be in many forms such as detailed corrections of the answers, making their misconceptions corrected for a particular concept, identifying their specific problems and asking them to take necessary steps to improve.
2) Time-saving of teachers
As this can be done in a collaborative manner, it will give freedom to any teacher from the respective subjects to annotate the assessments, the burden is no more to the individual teacher, it will be shared among the country or world. The burden of ev…

Importance of educational videos and solving its limitation by teachers assistance

By
Image
Many technologies have promised to revolutionize education, but so far none has. With that in mind, what could revolutionize education?


Why educational videos don't work?
1) Procrastination: Educational videos give freedom of anytime learning, but this can lead to procrastination. According to Parkinson's Law: "Work expands to fill the time available for its completion". But in case of video lectures or MOOCs there is no limit of time, so usually, we procrastinate. Limiting time to complete the MOOCs is also a bad idea, as it takes away its advantage of any time and anywhere learning.
2) Lack of a social interaction: We share emotions, feelings, discuss with the teacher, friends that come to our mind just like a true social animal and classroom brings a social two-way interaction, but it doesn't happen in case of MOOCs.
3) Answerability: No one is there to keep you accountable for finishing the course, no outward push, everything lies with intrinsic motivation or …
