Alternatives to Passwords
Are online passwords a thing of the past? Remembering a lot of different passwords can be tedious business. Most of us use multiple internet services like Facebook, Twitter, Google etc. and we have an account on every one of these sites and passwords. An average person has about 5-15 online accounts and expecting people to remember different passwords for all of them is unrealistic. Keeping one password is dangerous too as if one site is hacked, then all of your online accounts and maybe even your Credit Card information could be compromised. Most passwords are either too difficult to remember or too easy to guess. They are vulnerable to hackers too. A security breach showed that out of 32 million passwords, 290,000 were as simple as 123456 and abcd123.
Biometric Identification
One possible solution is using fingerprints. As every individual has unique thumbprints, they can be used to identify a person and hence be used in place of passwords.
A very futuristic seeming idea is to swallow a special pill which when inside the stomach, sends out an electric signal. This electric pulse has a code in it that unlocks the account. The acid in the stomach acts like the acid in a battery and provides the power required to project the electric pulse. Although this seems promising, but there are certain problems with this technique as well. The
The idea of biometric identification has its merits too. Devices equipped with cameras and microphones can use facial or voice recognition to identify users. But the problem with this is that biometric data cannot be changed. If passwords are hacked, you may get a new password, but if hackers have access to your biometric information then you will be vulnerable forever. fingerprint identification system can be fooled. One possible way of circumventing such a security system is to make a dummy with the thumbprint of the victim imprinted on it. The thumbprint identification system will not be able to differentiate between the dummy and the actual finger and in this way security can be compromised.
Electronic Tattoo![]()
Another possible way of getting passwords out of the way is to use an electronic tattoo. Each person has a unique tattoo which contains a code and an aerial. This setup sends a signal that can be used to login to your accounts. Many companies including Google are spending millions of dollars on research about these possible solutions to forgo passwords so it may be reasonable for you to expect to be beyond the era of passwords in a few years time.

Pornography Censorship: Myths and Realities
Internet Pornography is a major concern of parents and many adults as well. The subject is a taboo to some extent and there are a lot of myths that shadow our minds regarding this.
The quantity of the explicit material
It is often believed that adult websites must be among the top most visited sites. But to surprise and please many of us, only 7 adult content websites make it to the top 100 most visited sites.
According to an academic research, only 4% of the websites on internet are porn sites. The research was carried out on the top one million sites. But this figure is of course debatable due to many reasons.
Is the objectionable material only restricted to some specific sites?
Another interesting perspective that drifts in mind is that can we actually say that only the porn sites contain explicit material? The answer is a sure negative. Many ‘safe’ sites are flooded with adult content. For example, YouTube has a massive database of such objectionable material. Similarly, many social media websites like Facebook also have pages and groups that cater to the adult market. But these sites are never labeled and are considered safe.
Pornography Censorship
Many governments, including the British Government, around the world look into Pornography censorship very seriously so as to save the young minds from corrupting. But the question remains that whether reliable and effective censorship possible?
After being said that many safe sites could also be explicit, effective censoring would mean visiting and checking each and every page on the cyberspace. But this is not humanly possible owing to the fact that there are billions of websites.
Using an automated algorithm or software might seem like a solution but this would result in blocking of many safe sites and allowing access to many undesirable sites due to the quality of material that they offer. Hence, this remains a blunt tool!
Saving the kids
The conclusion is that the only possible way to save children from view adult content is constant supervision. No other way could possibly block the content. Proper training, good guidance and a hawk eye upon the children can fruitfully save their innocence!

Benefits of Using IT in Medical Field
Diagnosis and IT
There are many benefits of using IT in medical field. The modern IT provides many tools, aide and assistance in solving problems quickly and efficiently. Powerful computers have the ability to organize and present data in a tidy manner so that it is easy to draw conclusions from a set of raw facts. This can help medical personnel detect certain patterns of ailments in their patients which can lead to their spotting progression of diseases in a society. Doctors can also take some help from information technology in recognizing symptoms and locating the origins of the symptoms using the experiences of other doctors who have had patients with similar problems. Similarly, they can use others' experience while suggesting possible solutions to the diseases and deciding whether surgery is necessary or medications will be sufficient.
Data Management
Information Technology can also be helpful for doctors to keep track of their patients' medical history. The medical history, efficiently stored and presented, can help the doctor determine the medications that would suit the patient. It may also help him recognize if certain dangerous patterns are forming in the recurrence of a certain disease.
Most can made out of the potential of Information Technology if the medical personnel share their experiences in curing different diseases with others so that the other doctors can look up similar cases and know from the formers' experience the likely result of a certain suggested cure. But of course precautions have to be taken so that personal information of the patients is not made public. There are certain things that have to remain between the doctor and the patient. These details must not be compromised.
IT Professional in Medical Field
Doctors themselves cannot be expected to keep up with all the latest technological innovations and the new ways to share data. So it is the responsibility of the medical institutions to hire IT experts who can guide the institution into using IT efficiently and fulfill the promise of Information Technology. These IT people can collaborate with the medical staff to make sure that all the useful information is available to be used by others looking for the very same kind of information.
Information Technology has loads of opportunities and new ways to communicate and share information. Medical fields must also cash in on these prospects to the benefit of the society and the community as a whole.
Use of IT in medical field is increasing day by day and simplifying doctor's day to day work.
