ransomwareWannaCry Ransomware.

It has been 5 months since the WannaCry ransomware took down thousands of computers across the globe, and yet, the hackers behind it have not been found. the ransomware infected computers over the network by encrypting files and asked victims to pay between $300 to $600 in bitcoins (a cryptocurrency) to decrypt the files for future use.

The attackers further concealed their identity by converting the bitcoins into another virtual currency called Monero -an open source private untraceable currency that is considered to be more anonymous than the bitcoins as it require no account details to sign up. Monero can be used for making purchases in the deep web (part of web which cannot be detected by any standard search engine).

More than 3,00,000 computers were attacked in over 100 countries, the worst hit was Britain’s national health service, affecting 36 hospitals across the country. Globally companies that were affected include Nissan motors,FedEx , China National Petroleum, Renault SA, Hitachi, Sberbank of Russia and Russian interior ministry. Most of the companies were using the older version of Windows Software thus the threat around WannaCry ransomware increased, India was the third worst hit country.

Incidents were reported from some part of Kerala and Gujarat, in Odisha a government run hospital was affected, The West-Bengal electricity        distribution company and the Southern Railway divisions suffered glitches.bitcoin

The damage could have been worse had Marcus Hutchins , a 22-year old cyber security researcher, not activated a kill switch. His ‘accidental ‘ discovery stopped the attack from further spreading, he named his ‘kill switch’ contrary to WannaCry ‘WannaHappy; researchers were able to work on recovering the data to some extent.

As per the bot watching the bitcoin wallets tied to the ransomware attack , as on May 22 the perpetrators collected 48.86 bitcoins- estimated to be worth $104,436. According to IBM and Ponemon Institute’s Cost of Data Breach Study 2017 , the average cost of data breach for Indian companies surveyed is ’11 crore ; whereas, globally, the average cost of data breach in 2017 is $3.62 million.

The experts said “the main motive was not extortion of money but something more. An attack of such high caliber , was designed to asses the preparedness , and the impact of what such an attack could create”. perhaps the worst is yet to come and the world should be ready for it.

How Google is using AI to Prevent Blindness in Diabetics

google ai to prevent Blindness in Diabetics

Artificial Intelligence is in its development stage, and at many times we find it hard to find the best application of the technology for the betterment of human society. I think it is similar to the situation faced by us 70 years back from now when we didn’t know that what to use a computer for.

Many companies including Google are trying to find ways in which AI can be utilized in the best way possible to help simplify the challenging problems faced worldwide.

This story was recently featured on the homepage of Google. It shares a story about how a team at Google is using AI to help doctors prevent blindness in diabetics.

Google research scientist Varun Gulshan started this project in his home country India.

The Problem

diabetic

With seventy million folks with diabetes, India encompasses a growing drawback with diabetic retinopathy. It creates lesions within the back of the membrane that may result in total visual impairment.

Eighteen per cent of diabetic Indians already suffer from it. With 415 million diabetics in danger for visual impairment worldwide, it may be a world concern.

But the great news is that permanent vision loss isn’t inevitable. For those that square measure diagnosed early enough, medications, therapies, exercise and a healthy diet square measure extremely effective treatments for preventing additional harm.

The Tricky Part

AI diabetic retinopathy

If Google’s artificial intelligence may facilitate build designation diabetic retinopathy easier by accurately deciphering retinal scans, then maybe the visual modality of millions may be saved.

The difficult half was making a data set for the AI model to train on a task that involves grading and labelling all the scans one by one for various grades of severity.

Finding that downside would eventually need an outsized team of ophthalmologists whose grading of the scans would inform the AI model. And the team also requires quality data to provide more accurate information.

Training the model

The team was assisted by ophthalmologists at Aravind and Sankara Nethralaya to label the membrane pictures. when a couple of short months, the model was trained to spot key markers of diabetic retinopathy, like nervous tissue injury, swelling and haemorrhaging.

And with a bigger knowledge set, Gulshan was positive that they might build the model even additional correct.

They were successfully able to train the model and make a device from it.

How the Google AI Model Works to Detect Diabetic Retinopathy

  1. Over 50 ophthalmologists have manually reviewed more than 1 million anonymous retina scans, rating each for the level of diabetic retinopathy present.

  2. Each scan is reviewed multiple times and is graded manually on a scale of 1 (no diabetic retinopathy signs present) to 5 (extreme signs present).

  3. Each scan is reviewed multiple times and is graded manually on a scale of 1 (no diabetic retinopathy signs present) to 5 (extreme signs present).

  4. Once the algorithm has been trained, it can be used to power an application called an Automated Retinal Disease Assessment (ARDA). ARDA allows a user to upload a retina scan for instant analysis of diabetic retinopathy.

Verdict

Getting a diabetic retinopathy diagnosis will cause higher outcomes overall. ‘If you notice retinal unwellness at associate degree early stage after they don’t would like treatment’, Dr. Cuadros says, ‘it’s still a chance for the patient to know that polygenic disorder is starting to have an effect on their body.

This was just one of the ways in which artificial intelligence could be used to solve compelling problems faced by millions of people. Visit Google stories for more such stories.
