Face Recognition Based Attendance System For Exams

Problem Statements :-

Currently in India in exams such as NEET and JEE attendance is taken in many ways firstly the sheet is circulated to the students for signing and then there is a guy with video camera who records the video by going to each and every student and recording the Face of each  and every student. In this process there is a overhead of time , as firstly exam is very difficult and students have been assigned with very limited me to solve the paper and in that time they are also supposed to sign the attendance and be ready for video recording in this scenario if there is a problem in some identification issue of student or there are several instances where this methods might break the flow of students and might reach in some difficulty  for solving paper.

Solution :-

Basically by introducing this kind of state-of-the-art technology we can automate the attendance process in this high profile exams.
Step 1:
The face data of the student will be collected at the time of registration for exam and it will be stored in the  central database system.

Step 2:
This face data then will be used to mark present/absent for particular student on the exam date.

Step 3:
The attendance for this exams will be marked 10mins prior to the exam, once all the students are rest seated. They would have to face towards the camera for marking their attendance .

Additions :
 We may also implement an algorithm to trace real time video detection for assuring exams to be fair and copy free.

HOW TO HIDEFILESAND FOLDERS INSIDE IMAGE FILES.



There are many ways to hide and secure your sensitive information. Sometimes hiding sensitive information in plain sight can be the best way to hide it. And since there’s probably a lot of images on your computer, why not use them to hide text, without affecting the images and raising suspicion? Yes, it is possible to hide your text, files, and folders inside image files.
How To Hide Files and Folders Inside Image Files?
To hide files inside image files, you will need to have either WinZip or WinRAR installed on your computer. You can download either of these two off the Internet and use them without having to pay anything. Here are the steps for creating your hidden stash:
Step 1: Create a folder on your hard drive, i.e. C:\hide and put in all of the files that you want to hide into that folder. Also, place the image in the same folder that you will be using to hide the files in.
Step 2: Now select all of the files that you want to hide, right-click on them, and choose the option to add them to a compressed ZIP or RAR file. Only select the files you want to hide, not the picture. Name it whatever you want, i,e. “Hidefiles.rar”.

 Step 3: Now you should have a folder that looks something like this with files, a JPG image, and a compressed archive

Step 4: Now open command prompt. (Press Window + R to open Run, type CMD and Press ok)

Step 5: Type CD \ in command prompt to open root directory. Type cd hide to open your folder that contains Hidefiles.rar file and JPG image.

Step 6: Now type copy /b technotification.JPG + hidefiles.rar technotification.jpg and Enter.
Step 7: Now the files are successfully hidden inside the image technotification.jpg .
Now if you open the hide folder once again, you will see all the files there as it was before. You can delete them all if you want except the image because the 3 files that you compressed are placed inside the image. The image will look normal, nobody can know that there are 3 files hidden inside the image.

How to show hidden files inside a image?

If you want to retrieve those files back to normal. You’ll have to open the image with Winrar or Winzip software.

RUMOURS..ABOUT SAMSUNG GALAXY S9...(MUCH AWAITED PHONE)

Samsung Galaxy S9: release date, news and price rumors
The Samsung Galaxy S8 only hit stores earlier this year, but we're already hearing rumors of the Samsung Galaxy S9, with one report claiming the phone is already in the first few stages of production.
The rumors are now coming thick and fast for what the new phone will look like, especially as we've now seen the Samsung Galaxy Note 8 and the iPhone 8 is imminent, so we've rounded up the best of them here - as well as answering some key questions.

What's the new Samsung Galaxy S9 news?

The latest leaks suggest the Samsung Galaxy S9 will support modular accessories but without a fingerprint built into the screen (sadly, still around the back). It'll have the new powerful Snapdragon 845 chipset powering things but it will stick with 4GB of RAM, rather than 6GB as other modern smartphones have.

What will the Samsung Galaxy S9 price be?

We're expecting £639 / $725 / AU$1200 based on current projections, as we're expecting the Galaxy S9 to come in around the same price as its predecessor. Given we're not expecting massive design changes, we doubt too high a price rise.

What's the Samsung Galaxy S9 release date?

We're expecting a March 2018 launch. While the recent rumors suggest the S9 will launch in January, that's too early given people are locked into contract cycles. 

Samsung Galaxy S9 price and release date

We so far know nothing about when the Samsung Galaxy S9 will be announced, so we'll just have to go off what Samsung has done in the past.
Samsung announced the Galaxy S8 in late March, so we'd expect it will follow up with the Galaxy S9 roughly a year later, at the end of March 2018. 
But it was late in announcing the Galaxy S8 in 2017 - the company waited about a month longer than normal, so it's possible that the S9 will land around the end of February, in which case it might be launched at Mobile World Congress 2018, as that's likely to take place at that sort of time.
Recent rumors state that - due to the fact the OLED screens that are likely to be used in the phones are being created earlier than usual - the Galaxy S9 will launch in January, but that would be far too early for many reasons, not least because people wouldn't be eligible to upgrade to it right away.
What we can safely predict is the Samsung Galaxy S9 is sure to be expensive, as the Galaxy S8 launched at $720, £689, AU$1,199.

Samsung Galaxy S9 news and rumors

Not much is known about the Samsung Galaxy S9, but some sources claim the company has already started work on producing its next flagship phone.
The Bell reports unnamed industry sources saying that Samsung has been hard at work on the display panels for the Galaxy S9 since late March 2017. If Samsung has started work on the S9’s display panels that’s apparently about 6 months earlier than usual.
That doesn't come as a massive surprise, as many companies start work on their phones before one generation has even been announced, but it's good to get the rumors flowing already about the next Samsung phone.
Samsung and Qualcomm have also started working on a new mobile chip according to The Investor. The chip is apparently likely to be called the Snapdragon 845 - up from the Snapdragon 835 found in some versions of the Galaxy S8 - and is supposedly going to be used in the Samsung Galaxy S9.
The Snapdragon 845's use has again been rumored, this time by a reasonably reliable source, so it's looking likely.
So far we don't know anything about the power or performance of the Snapdragon 845 chipset, but we'd wager it won't be the only one Samsung uses, with a new Exynos chip likely headed to S9 handsets in some parts of the world.
And speaking of a new Exynos chip, Samsung has revealed that it has developed LTE modems for the next generation of its chips. Why should you care? Because these modems support theoretical download speeds of 1.2Gbps - faster than any other phone, meaning you could potentially download an HD movie within just 10 seconds.
However, it seems unlikely that we'll get 6GB of RAM inside, which is what many smartphone brands (especially Asian ones) are doing - with Samsung set to stick with the much-more-sensible 4GB spec instead.
It seems one of the big chipset developments may allow the company to include a much bigger battery too. A new report suggests Samsung will now use Substrate-like PCB tech that will allow the Exynos chipset manufacturer to include a bigger battery without increasing the size of the processor.
It may mean the extra battery won't be on the Qualcomm Snapdragon toting Galaxy S9, but it could mean big improvements for those who get the Exynos version. 
One of the big issues with the Samsung Galaxy S8 was the fact the fingerprint sensor was shoved to the back of the phone, after rumors abounded that the reader was supposed to go under the display's glass but it just didn't work.
However, the new Qualcomm Fingerprint Sensor can sit below quite thick displays, and OLED technology (used in Samsung flagship phones) was specifically mentioned.
All that points to the Samsung Galaxy S9 having fingerprint-sensing technology below the glass... and if Apple integrates that into the iPhone 8, then Samsung will have to follow suit.
Then again, one tipster claims an in-screen scanner isn't in the cards, so don't count on that feature just yet.
And the Galaxy S9 is sure to get some new features too, one of which could be a modular design, with magnets on the back letting you attach hardware accessories (which could take the form of battery packs, zoom lenses or any number of other things), a bit like Motorola's Moto Mods.
Only one source has mentioned this possibility so far, so we'd take it with a huge pinch of salt, but it could be a key selling point of the S9 if true.
Aside from that, in late 2016 Samsung licensed a new glass coating technology that makes water bounce off your smartphone screen. Samsung plans to include this tech in an upcoming phone, so it may mean the Galaxy S9 is much easier to use in the rain. Watch the video below to see how the technology works.

Samsung Galaxy S9: what we want to see

The Samsung Galaxy S8 is still the new shiny, but we've had a brainstorm about the improvements we'd like to see on the Galaxy S9.

1. A foldable screen

Rumors of the Samsung Galaxy X - a phone with a foldable display - have been building for the past few years.
A Samsung executive has told the media that the company doesn't plan to launch a fully foldable phone until at least 2019, but plans may change in the coming months.
For Samsung to build the first truly foldable phone and sell it in 2018 would be a major boost to the South Korean company, and may change the way we use our phones forever.

2. A smaller version

Samsung doesn't offer an Android alternative to the iPhone SE. Instead the company has the Galaxy S8 and Samsung Galaxy S8 Plus for the mid-sized and larger phone lovers out there.
We'd like to see Samsung embrace a smaller display on the Galaxy S9, or offer up a third version that includes a smaller screen instead.

3. A fingerprint sensor under the screen

It's clear Samsung wanted to move the fingerprint sensor under the screen for the Galaxy S8, but didn't have enough time to make it work.
Instead Samsung included a touch-sensitive home button under the display, which is useful, but we'd like to see the company go the full way and include a fingerprint sensor below the screen

4. A lower price

Samsung has had to increase the price for the Galaxy S8, making it one of the most expensive flagship phones on the market.
If you're buying it as part of a two-year deal it's not as expensive as you'd expect, but we'd like to see Samsung reduce the price for next year's phone if at all possible.
  • VERDICT;
IT's WOTH WAITING TILL NEXT YEAR FOR THIS PHONE....

LENOVO K8 PLUS..FULL DETAILED SPECS UNLEASHED..

·         Lenovo is teasing the smartphone on social media
·         Flipkart is also teasing the launch of the smartphone
·         Lenovo K8 Plus said to bear a dual rear cameras, stock Android
Lenovo recently launched the K8 Note to bolster its K series of smartphones along with a major step to ditch its Vibe Pure UI for the stock Android interface. Ahead of its launch, Lenovo was also reported to be working on another K series smartphone, dubbed K8 Plus, that got listed on a benchmark listing website. Lenovo India has now confirmed the launch of K8 Plus on Twitter. Besides, Flipkart has officially announced that the smartphone will be unveiled on September 6, and exclusively sold on the e-commerce website in India.
On Tuesday, Lenovo India posted a teaser video of K8 Plus on Twitter, showing a dedicated media button on the left side of the smartphone. The tagline that accompanies the video teaser reads, "Do you look at your smartphone and always #KraveForMore? It's time to end that with the new and powerful #LenovoK8Plus. Coming soon!".
The upcoming Lenovo K8 Plus is going to be a mid-range smartphone, Flipkart said in its release - however the exact price will only be revealed at the time of launch. Lenovo will also be going ahead with its latest move to ship stock Android to this smartphone, with the latest Nougat version. Moreover, Flipkart says that the smartphone is also expected to sport a dual rear camera setup, as per a social media teaser posted by Lenovo that shows Bokeh effect in action. However at the time of writing, we could not find such a post on Lenovo's social handles. The Lenovo K8 Note bears dual rear cameras, and so it does seem likely that another smartphone in the same series has the same feature.
As we mentioned, the Lenovo K8 Plus was spotted on popular benchmarking website, Geekbench, where some of its specifications were revealed. The smartphone can be expected to come with Android 7.1.1 Nougat, powered by a 1.7GHz octa-core MediaTek Helio P25 (MT6757CD) SoC. The benchmark listing of the Lenovo K8 Plus also disclosed that it might sport 3GB of RAM, in addition to aforementioned specs.



Hands on: Samsung Galaxy Note 8 review-(The world’s best phone, but bigger and more powerful....)

OUR EARLY VERDICT

The Samsung Galaxy Note is almost dull in its predictability – it's a hugely powerful phone that's great for multi-taskers, has a mind-blowing screen and an improved dual camera, and costs an absolute fortune.

FOR

  • So much power
  • Strong camera
  • Beautiful screen

AGAINST

  • SO expensive
  • Easily-smudged rear
·         Let’s get this out the way now: if the Samsung Galaxy Note 7 hadn’t been so prone to explosions the Note 8 would have been a slam dunk of a phone, so impressive is this new handset at first sight.
·         Well, it very much still is – there’s very little wrong with the Note 8 if you’re a fan of the phablet – but the spectre of last year's debacle is still hanging over its shiny body.
·         As with the Galaxy S8, Samsung has promised that its rigorous battery checks will prevent such incendiary incidents from happening again – and that’s clearly the case with the Note 8 too.
·         As such, you can disregard the issues from last year if you go for this new and powerful handset from Samsung... apart from the inevitable questions / mocking you’ll have to put up with when you pull it out for the first time.
·         As mentioned, you’ll have to be a fan of Samsung’s phablets specifically to be drawn towards the Note 8 over the Galaxy S8 Plus, for instance, because despite having more power and a larger and sharper screen than anything Samsung has launched before, it's got a smaller battery than the S8 Plus and is more expensive too.

Samsung Galaxy Note 8 release date and price

The Samsung Galaxy Note 8 is available to pre-order on August 23 in the UK, Thursday, August 24 in the US and Friday, August 27 in Australia. It’ll be in US stores on Friday, September 15, in Australia on September 22, and around those key across other key territories, such as the UK.
In terms of price – get ready for a very expensive phone. In the UK it’s going to be £869 SIM-free, and Note 8 deals will start at around £60 per month if you want a free phone – very much at the pricey end of the scale.
In the US, it costs $930 for a Note 8 unlocked through Samsung, while carrier like Verizon are charging a hefty $40 a month. T-Mobile is only charging $30 a month... with a $210 downpayment. Luckily, there will be Note 8 deals in the US.
You can order the Note 8 in the US through Samsung, AT&T, Verizon, T-Mobile and Sprint as well as smaller carriers like C Spire, Cricket Wireless, Straight Talk, US Cellular and Xfinity Mobile. Best Buy, Walmart and Target will also carry it.
In Australia, the Note 8 is easily the most expensive Galaxy phone to date, with an RRP of AU$1,499 — that's a good $150 dearer than even the Galaxy S8 Plus, which sells for AU$1,349. 
The good news is that pretty much every major Australian telco is carrying the device, with the cheapest plans starting at around $80 per month on a 24-month contract. If you're looking to pick up the handset down under, our Aussie deals team has a round-up of the best Australian Note 8 plans on offer.

More screen than ever before

The big thing about the '8' series of Samsung phones is the Infinity Display, which is Samsung's name for the edge-to-edge, bezel-less display that adorns the front of the handset.
And the Galaxy Note 8 has the biggest version of this display yet seen, with a 6.3-inch QHD+ offering that just looks sublime. You're really just picking up a screen with the phone attached somewhere on the back.
The quality of the screen hasn't been updated a huge amount from the Galaxy S8 and S8 Plus – it's still the same Super AMOLED technology with HDR support baked in, but that's no issue, as we consider Samsung to be making the best phone displays in the world right now.
It's brighter and more colorful than anything we've seen before - although we're awaiting the lab tests to confirm this - making it the best phone to watch movies on again if so.
The design of the phone complements the display well, with the slightly rounded edges on the back having a touch of sharpness about them to make the phone easier to grip.
It was interesting to note (sorry...) that we tended to pick up the phone more in the middle of the display, rather than cradling it from the bottom – this made finding the buttons and the rear fingerprint scanner easier to hit (more on that later).
The buttons all protrude well enough to be easily clicked, and weirdly for a phone of this size it didn't feel too cumbersome in the palm. It was even possible to reach the full width of the screen with a thumb, although you can forget hitting the corners.
It's got three flavors of internal storage: 64GB, 128GB and 256GB. On top of that there's a microSD slot (up to 256GB supported) and with an S Pen port too, there's a lot to pack into the Galaxy Note 8, and Samsung has done well to put it all together in a package like this (especially as it’s IP68-rated for water and dust resistance).
However, the Gorilla Glass 5 still feels lightweight, and still borders on feeling a little like plastic. This does save weight, and the overall construction feels premium, but there's a tactility to metal – or even ceramic – that we miss here.

Fingerprint mistakes are repeated

However, when it comes to design choices, we're disappointed that Samsung has maintained its stance of putting the fingerprint scanner on the back next to the camera.
We'd assumed that last-minute design changes had meant the Galaxy S8 had to have the biometric unlocking method put on the rear, and that this issue would be solved with the Note 8.
Samsung's executives will tell you that they use iris scanning to unlock their phones most of the time, but in our testing of the Galaxy S8 we didn't find this accurate enough... and that still seems to be the case here.

Double take

The camera on the Samsung Galaxy Note 8 is probably one of the biggest upgrades over anything else in the South Korean brand's range, with dual 12MP sensors on the rear.
As on Apple's iPhone 7 Plus, one of these is telephoto, so you can zoom in 2x to your subject with no loss in clarity. You can also use the two sensors together to create a background blur effect, either when taking a photo or after you've shot it.
However, this feature needs some work. In our testing we noted (dammit, again...) that the Note 8 didn't do a very good job of working out which elements to blur in the live preview very well, with subjects with detailed outlines, such as plants, proving especially problematic.
We'd also question whether being able to blur the image post-shot is a good idea. What Apple does well is keep things simple, and a 'background defocus' mode that did just that would have been a better idea here. 
Perhaps give users a 'geek-out' mode where they can enable tuning, but the average user is presented with a lot of options on the Note 8 camera, which always feels like something of a danger.
What you won't find an issue with is the picture quality. It's as excellent as ever, and combined with the Super AMOLED screen your snaps always look brilliant – even if taken quickly, such is the speed of autofocus.
With one sensor on the rear taking wide-angle, f/1.7 images and one taking zoomed f/2.4, you should be able to get good low-light performance from the Note 8, as well as being able to take a wide range of styles of photo.
That said, in our low-light comparison with the iPhone 7 Plus, the results from Apple's setup looked brighter, albeit with more noise. We're not going to pass judgement on that though, as it needs more of a look.

Paired up

Another small update that came with the Galaxy Note 8 was the pairing of apps. This is pretty much as it sounds: swipe from the edge of the screen in any mode and you'll be able to see pairs of apps that you use regularly.
Play music every time you turn on maps in the car? Have both in split screen with a single tap.
It's not the most exciting feature in the world, but does push the point of Samsung's split screen capabilities better than anything.
Whether it comes to the Galaxy S8 and S8 Plus remains to be seen - but it would be a neat feature to bring across.

The most useful S Pen ever made

The S Pen is – along with the raw power inside – the thing that defines the Note series, and the new version of the stylus is better than ever. Its 4,096 levels of pressure sensitivity, a more flexible tip and nice weight make it a pleasure to use. 
Samsung, once again, has wheeled out the idea that 'this feels like writing on paper' and while it utterly doesn't (because this is rubber on glass) it's closer than ever before, and highly accurate.
The new features offered, such as the option to create an animated GIF from your doodles, and to translate more words in a single swipe, are among the most useful that Samsung has offered with the S Pen.
We never felt that being able to snip out parts of pictures was a great tool to have, but the Galaxy Note 8 feels more useful to the millennial generation than ever.
Bixby bursts forth
The Galaxy Note 8 should really be known as the phone that brings Bixby, Samsung's digital assistant, to the fore, with the full suite of features enabled from launch.
That means that alongside the Bixby Home screen (which is still more perfunctory than amazing as a feature) and Bixby Vision (which has a long way to go to convince us it's any use) we'll have Bixby Voice on board, offering the full range of ways to interact with your phone.
·         Bixby Voice: everything you need to know
It'll mean you'll be able to press the physical Bixby button and have the phone perform all manner of tasks – and in the demo we've seen, it's incredibly accurate and powerful for a voice assistant.
It won't mean a lot right now, even to Samsung phones, but where we derided Bixby's presence on the Galaxy S8 at launch, the Note 8 will offer far more functionality.

Battery

There’s always a worry with any phone when you don’t see an industry-leading number in the battery spec column, and that’s the case with the Samsung Galaxy Note 8.
The 3300mAh power pack just feels too small for a phone that has these specs. More RAM (6GB), a powerful CPU (either the Qualcomm Snapdragon 835 or the Exynos 8895), and a wider range of functionality means people will be using the Note 8 a heckuva lot.
It's a smaller battery than the Galaxy S8 Plus (which offered a 3500mAh option), and this could be an issue for Note users. 
Yes, Samsung has optimized its software well, and yes, there needs to be space for the S Pen – but we expect the best of the best from the Note range, so we'll have to wait and see how well the device performs in our usual battery (sorry, again, sorry...) of tests.

Anything else I need to know?

One of the things Samsung is keen to promote in its new range of phones is the DeX desktop experience, where you plug the phone into the dock and have a full desktop experience if there's a monitor, mouse and keyboard handy.
This seems more in keeping with the Samsung Galaxy Note 8 than the Galaxy S8, as the Note is designed to be more of a productivity tool.
The demo we were shown did show off an improved DeX, with a more fluid desktop experience and more full-screen Android apps that can be used effectively with a keyboard and mouse, but we saw nothing to convince us that this was a complete desktop replacement.




Biometrics still need sorting

Samsung still hasn't solved the issues around the biometric unlocking of its phones – at least going on what we could see in our limited testing.
The iris scanner failed on a couple of occasions, despite being in the right lighting conditions, and while we didn't test out facial recognition we didn't see anything that suggested Samsung has solved the issue of these options being slightly inaccurate and erratic.



Early verdict

Samsung didn't have to do much to make a decent Note 8, such was the impressive nature of the Galaxy S8 and S8 Plus.
Essentially, this is just a beefed-up version of those phones with a fancier camera – more options, but overall still the same quality underneath.
The power will attract some users who want 6GB of RAM alongside the latest CPUs on the market, but they won't really change the performance for most users.
In reality we can see people buying this phone for the larger display and improved S Pen – and despite the higher price, that could attract a large audience indeed.
As long as the Note 8 doesn't run into any similar issues to last year, we're going to be treated to an epic battle between Samsung and Apple this year to see which brand can offer the most impressive handset.
