Is EVM hacking possible?

Elections results are out and BJP has made a tremendous victory in UP and Uttrakhand. But the opposite party has taken out new excuse to mark their existence. EVM HACKED! Is it so?

Earlier we use to make use of ballot paper for casting vote but as the population of India increased counting in the tradition way became difficult. Here came the need of EVM. EVM was first used by Kerala in 1982 at some polling booth and after 2004 EVM was mainstream. EVM machines are manufacture at 2 places in India, first is Bharat Electronic Limited located in Bangalore and second is Electronic Corporation India limited which is located in Hyderabad.

Both of them produce exactly same machine comprising of two part, first is balloting unit which is in front of voter at the time of vote and other  is at the operator end who give command to cast a new vote. EVM machine can hold 16 different parties name and we can maximum connect 4 machines in parallel making the total count of 64 different parties. After all votes are cast, these machines are sealed and finally open at the time of counting.

It seems like that it is tempers prove but still there are some loopholes. There are 2 ways to hack it, first is by changing the display with new display embedded with Bluetooth so that we can alter the screen count through Bluetooth device and other is to directly rewrite memory but as these machines have no ports, therefore for the purpose of rewriting memory you have to open machine. However, both the ways require physical presence of machine with you and imagine manipulating thousands such machines will take how much time.

Now, do you think were the EVM hacked?

Election commission is planning a new system known as Voter Verified Paper Audit Trail where voter can see to whom they have cast vote by checking the confirmation receipt and later on this paper can be used as audit. It was used at 8 places in 2014 election and expected to use everywhere in 2019 election.

How fingerprint sensor works?

There are plenty of sensors present in our smartphone and fingerprint sensor is one of the most prominent sensor in them.

The password formed by the combination of letter and word can be guessed with the knowledge of computer programming or by hit and trial method. So there was a need of much stronger security, hence fingerprint sensor came into the picture.

There are three different kind of pattern namely Arch, Loop and Whorl which make each fingerprint unique. Fingerprint sensor analyze them for better security and block unauthorized access. Optical fingerprint sensor and Capacitive fingerprint sensor are two major classification of fingerprint sensor.

As one taps his finger from different angle while registering fingerprint for the hardware, Optical fingerprint sensor take snap of finger from different angle and prepare a map removing a common area. This map is stored in the memory and whenever a user tries to open the device with his fingerprint, optical fingerprint sensor makes sure that it is matched with the previous map present in memory. On matching it grant access to use otherwise denied. Map is prepared by taking care of key information of finger like ridges bifurcation, smaller ridges and ridges end. It also takes valley i.e. the gap between two ridges in account to prepare map.

Another kind of fingerprint sensor, i.e. capacitive fingerprint sensor makes use of capacitor of very small size which is placed on the fingerprint sensor. When a user presses his finger on the sensor while registering, ridges area gets activated and capacitor present in the valley region didn’t get activated, and thereafter it prepares a map for the same which is recalled and matched when a user tries to unlock hardware with his fingerprint.

As optical fingerprint sensor takes snap of finger from different angles, so it can be fooled by presenting a copy of fingerprint in front of it, whereas capacitance fingerprint sensor makes use of capacitor and work on ON-OFF concepts so it can’t be fooled easily.

Acceptance rate i.e. how quickly and accurately it identifies fingerprint. Normally the acceptance rate is 90% which make sure that no unauthorized person accesses the account.

Why do my eyes glow red in photos?

You may have encountered the red eye option in every photo editing software  and sometime you too have encounter these magical red eyes in yours  photos, if not, go and click a photo in dark. So,  what actually are these red eyes?

The blame for this  go to the bright flash of camera, and how your eyes adapts to changes in light. Your eyes are basically fluid filled orbs that can detect light and sense messages to your brain, so you can see images. Light passes through a thin membrane called cornea, then a hole called the pupil, and then a lens so it can be focused and absorbed by photoreceptor cells in the back of your eyes. Your pupil filled by this muscles filled structures called the iris, which is the colored part of your eye. You don’t consciously move these muscles, but they control how big your pupil is, and how much light can in.

When it’s dark your iris make the pupil wider to let more light into your eyes and when it’s bright your pupil get contracted.  So, the Red Eye Effect usually happens in a dark environment when your eyes are widen enough. Normally, all the light that enters your eye is absorbed by photoreceptors, or by a pigment called Melanin in a tissue layer in the back of your eyes-the same pigment that influences the color of your skin, hair and iris. And since your eyes absorb all colors, make pupils look black. But if there is sudden a bright camera flash and all that light floods into your eyes, before your eyes have time to contract. Some of it might reflect off the blood vessels in back of your eyes, making it glow up.

So, how to fix them? To fix such problem, there are camera with multiple flash i.e. before glowing actual flash, they glow demo flash which help your eyes to adjust. You can also skip from red eye effect, either by not directly focusing on camera or by shifting the focus of light to nearby object.

Is there nano GPS chip in new 2000Rs notes?

New notes are about to come in the market and people are talking about GPS technology in these new notes of 2000Rs. With this GPS you can be tracked down if there is a huge collection of notes in your house even if you buried them deep in the ground. Your WhatsApp may be popping up with the message of having nano GPS chip in upcoming new notes, now if I say that there is also a fingerprint scanner in these note so that no one else can use your note and these note will slap you if you misuse it, you will laugh rolling on the floor. Actually, there is no such nanochip in these upcoming new notes, rumors are saying that nano chip embedded in notes will receive and reflect signal coming from the satellite and too that this chip needs no power. Just think that how the signal will be able to maintain their strength all way down to Earth, and if some how this may be possible then to embedded chip will not be able to reflect back it completely to satellite. Now just think if we kept these notes in the metal box, then signal can't  track it due to faraday cage which will be formed.

Beside this fake news of GPS, there are really some new features like Mangalyan and Red Fort on 2000 and 500 notes respectively, Bharat is also written on security thread and the too amount of note is written in 15 different languages.

Myths that you still believe about TECHNOLOGY-

With the advancement of technology, myths about technology are also growing. Let’s have a look at them-

1. File deleted from recycle bin cannot be restored-  Actually, it is not so, even the file deleted from recycle bin can be restored, until its memory location is overwritten by any other file. So, even if you deleted a file by mistake, it can be restored.

2. More bar on a cell phone means better signal- Another most common myth is related to the number of signal bar i.e. Signal strength is directly proportional to the number of bars. Signal bands only depict your closeness to server antenna. Signal strength depends on crowd on that server and weather conditions.

3. Apple system are not vulnerable to Virus- Another most common myth is related to effect of virus on Apple Systems. Even they too are vulnerable to Virus but as there are more Windows users than Mac, therefore virus developers focus on harming Windows rather than Mac.

4. Internet and www are same-www is a subset of the Internet and not a synonym for it. Internet comprise of www, college networks, industry network and different other networks.

5. Expensive HDMI cables are better-HDMI cables transfer digital signal, so even if you buy gold plated cable of Rs1400 or non-gold plated HDMI cable of Rs.350, there will be no difference in picture quality. So, spend wisely.
