"Ministers have paused a planned update to the NHS Covid-19 app after Apple and Google blocked it from their stores over privacy violations. The app, which aids contact tracing in England and Wales, uses technology built by the Silicon Valley companies to track interactions between users with their bluetooth signals and venue "check-ins"."

"When you take a photo, your smartphone or digital camera stores "metadata" within the image file. This automatically and parasitically burrows itself into every photo you take. It is data about data, providing identifying information such as when and where an image was captured, and what type of camera was used."

"Bitcoin is stored on software known as a digital wallet that is secured through encryption. A password is used as a decryption key to open the wallet and access the bitcoin. When a password is lost the user cannot open the wallet. The fraudster had been sentenced to more than two years in jail for covertly installing software on other computers to harness their power to "mine" or produce bitcoin. When he went behind bars, his bitcoin stash would have been worth a fraction of the current value. The price of bitcoin has surged over the past year, hitting a record high of US$42,000 in January. It was trading at US$37,577 on Friday, according to cryptocurrency and blockchain website Coindesk."

"Personal information of more than 243 million Brazilians was exposed for more than six months thanks to weakly encoded credentials stored in the source code of the Brazilian Ministry of Health's website. The data leak exposed both living and deceased Brazilians' medical records to possible unauthorized access. The incident was the second reported by Brazilian publication Estadão and among several others recently affecting South America's largest nation's healthcare system."

"Users post violent and hateful content to Facebook and Twitter all the time, they argued - and no one was demanding those platforms get the boot from the app stores."

"Apple and Google's tougher enforcement could preclude such apps from becoming realistic alternatives to the mainstream social networks. They now face the choice of either stepping up their policing of posts - undercutting their main feature in the process - or losing their ability to reach a wide audience."

"This is called a supply-chain attack, because it targets a supplier to an organization rather than an organization itself - and can affect all of a supplier's customers. It's an increasingly common way to attack networks. Other examples of this sort of attack include fake apps in the Google Play store, and hacked replacement screens for your smartphone."

"The bionic leaf is an outgrowth of Nocera's artificial leaf, which efficiently splits water into hydrogen and oxygen gas by pairing silicon - the material that makes up solar panels - with catalyst coatings. The hydrogen gas can be stored on site and used to drive fuel cells, providing a way to store and use power that originates from the sun."

"DO YOU WANT YOUR PALM STORED IN THE CLOUD?"

"The Joker malware circumvents the Google Play app vetting process through a combination of code tweaks, execution method variation, and changes to how it downloads the payload allowing it to function, steal information, and trigger the WAP service sign-ups. Google has removed the 16 infected apps from the Play Store and disabled them on devices where they are installed, thought to be in the region of 120,000 devices. "

"Before we go deeper, it's important to note that there are two approaches to facial - or any biometric - authentication: "match on server" and "match on device." The former approach shares some of the risky aspects of facial recognition technology because it stores the details of one's most personal features-your face or your fingerprint-on a server, which is inherently insecure. There are some well-publicized examples of biometric databases being hacked, which is why so many companies are committing to only do on-device biometrics."

""The attraction for jihadists of these platforms is that the developers of these decentralised platforms have no way of acting against content that is stored on user-operated servers or content that's shared across a dispersed network of users, " BBC Monitoring senior jihadi specialist Mina Al-Lami said. "It's really all about privacy, freedom and encryption."

"KUALA LUMPUR: Facial recognition technology today is increasingly being used by law enforcement agencies, banks, hotels, airport and now convenience stores to detect and arrest criminals quickly. Kuala Lumpur Police chief Datuk Seri Mazlan Lazim said by the installation of facial recognition closed-circuit television (CCTV) cameras in convenience stores the faces of criminals can be clearly recorded to trace their identities."

"The app, called Care19, and produced by a company called ProudCrowd that also makes a location-based social networking app for North Dakota State sports fans, generates a random ID number for each person who uses it. Then, it can "anonymously cache the individual's locations throughout the day," storing information about where people spent at least 10 minutes at a time, according to the state website. If users test positive for the coronavirus, they can provide that information to the North Dakota Department of Health for contact-tracing purposes so that other people who spent time near virus patients can potentially be notified."

""Somehow the little brats worked out that if enough users gave the app a one-star review it would get booted off the App Store. Tens of thousands of reviews flooded in, and DingTalk's rating plummeted overnight from 4.9 to 1.4. The app has had to beg for mercy on social media: 'I'm only five years old myself, please don't kill me.'""

"These ranged from the mundane (Facebook may change its terms of service at any time) to a reminder that Facebook may store and process your data anywhere in the world, meaning it might be subject to different data protection laws. When scanning license agreements from Google, Do Not Sign told me the company reserves the right to stop providing its services at any time and that its services are used at the users' sole risk."

"Once it's verified, the transaction's information, plus both your digital signature and your friend's digital signature, are stored in a block alongside many other transactions like it. Once the block is full, it gets a hash, which is a unique code that sort of acts like its nametag. It also stores its position on the chain and the hash of the previous block on the chain. (Here's an example block to illustrate what kind of information is stored there.) "

"Many services retain the data they harvest indefinitely, and some have been caught storing (and losing) the data without encryption: for example, in 2017 the Greater Manchester Police were found to have lost data from victims of violent and sexual crimes, which had been stored unencrypted on DVDs and sent through the post."

"Teslas are incredibly data-hungry, storing massive troves of data about their owners, including videos of crashes, location history, contacts and calendar entries from paired phones, photos of the driver and passengers taken with interior cameras, and other data; this data is stored without encryption, and it is not always clear when Teslas are gathering data, and the only way to comprehensively switch off data-gathering also de-activates over-the-air software updates for the cars, "
