Verum, Wickr and Threema: next generation secured messengers

Still using WhatsApp and Facebook Messenger? Think Telegram is completely reliable? Or maybe you still can’t give up trying to talk normally in Viber? Then we have a serious conversation with you.

The 21st century has given us access to communication, instant communication with each other, no matter where we are in the world. But at the same time, we all became vulnerable — personal information was in plain sight, it was easy for us, we were simply controlled. Conversations are no longer private. “You have to pay for everything. This is the price of an affordable connection”, someone might say. No, we disagree with this statement. Everyone has the right to the confidentiality and secrecy of their data. We present you the top 5 most secure messengers of the new generation.

Verum

You don’t even need a SIM card to use Verum messenger. No phone tethering. The app has built-in VPN and end-to-end encryption. When you first get to know the application, you will create an individual key pair and you will have a unique identifier. And the Verum developers have solved our eternal problem — if someone takes a screenshot in the chat, you will immediately find out about it. Checkmate! No more leaked correspondence. You can add up to 10,000 people to a group chat, and the app is translated into 15 languages. No one, except the recipient, can view your correspondence, no matter what it contains — photo, video, audio. And even if you suddenly lose your phone, no one but you will be able to enter the application. To do this, you can set a password for the entrance or require it to be entered after a certain time. And so that you are completely calm about the confidentiality of communication, the Verum developers have provided the ability to automatically delete all correspondence after the time you set. The interface is minimalistic and stylish. Verum is currently only available for download on IOS. It can be purchased from the App Store for $12,99. Yes, it is paid, like some of the ones below, as these are the best messengers in terms of security. But, believe me, those «free» applications that are on your phone also have a price — you pay for them with your personal data.

Wickr

Time-tested anonymous messenger. Even if you have never come across it face to face, you are sure that you have heard this name for sure. As with Verum, you do not need to have a SIM card in order to attach the app. When registering, you create an ID and password. Transferring files to third parties is impossible, as well as a screenshot of the correspondence. If you decide to erase the entire communication history, there is no way to restore it. The developers have equipped the Wickr feature with a temporary image and text that will automatically disappear after the recipient has viewed them. It is very convenient that the messenger can be installed on a PC, as well as by the standard — available for IOS and Android. Wickr is available in a free version (Wickr me) and also in a paid version (Wickr pro / Wickr ent) for corporate communication. Due to this interface, the application is a little more complicated than that of other messengers.

Threema

Application servers are located in Switzerland, which in itself, you must agree, is already a guarantee of quality. Just like the previous applications — Verum and Wickr — Threema does not require you to bind to a phone number. And we like this trend, as it has long since lost its relevance. Something like a place of registration, isn’t it? Instead of a number, you will be given keys — private and public, according to the scheme you are already familiar with. It is also possible to password-protect individual chats. The information is not saved in the application, but on your phone. Messages are deleted immediately after you or your interlocutor read them. Everyone began to discuss Threema after the messenger refused to give out encryption keys to Roskomnadzor. After this incident, the number of users of the application increased significantly. Threema can be downloaded on IOS and Android for about 3$.

Confide

A very interesting, in our opinion, application for safe communication. The peculiarity of this messenger is that messages are displayed closed, in the form of rectangular shapes. In order to read the text, you will need to slide your finger over it. This feature protects you from annoying peeping at the phone screen. Until you make sure that no one is standing behind you, the message will be impossible to read. True, Confide requires binding to your mail. Here, too, it will not be possible to take a screenshot, since you simply cannot then open it or send it to someone. The app is free, but there are paid features.

Signal

To install this application, you will already need your phone number and contact list. Despite this breach of anonymity, the messenger is still pretty safe. Developers used open source encryption, making it available to their own research of various problems that may arise when working on different operating systems. Unlike WhatsApp, Signal will not collect data about your preferences, after which you are usually offered an advertisement for the product you just hinted at in a conversation. Before starting a conversation, you can double-check the security of your conversation thanks to the additional two-way session verification. The developers have also not forgotten about the function of disappearing messages. You can set a password to sign in to Signal, or you can use the face and fingerprint recognition system. The application is free and available for all operating systems.

You Can Watch an Exclusive Avatar: Fire and Ash Scene on TikTok Right Now

Disney and TikTok partner on an immersive content hub for James Cameron’s latest movie about the alien Na’vi.

If you’re not quite ready to head to the theater to watch Avatar: Fire and Ash, an exclusive scene preview might sell you on the visual spectacle. As part of a new collaboration with the social media giant, Disney is posting snippets of its new movie to its TikTok account.

This scene isn’t part of any trailer and won’t be posted to other social media accounts, making TikTok the only place you can view it — unless you buy a movie ticket. A first look at the new movie’s scenes isn’t the only Avatar-related bonus on the social media platform right now, either. TikTok has partnered with the house of mouse to bring an entire «immersive content hub» to the app.

A special section of TikTok includes quizzes and educational videos that explore the alien world of Pandora shown off in the movies. On TikTok, you can take a personality quiz to find out what Na’vi clan you most closely align with and unlock a special profile picture border to use on your account.

Science and fiction blend together with a series of videos from real doctors who explain the basis for some of Avatar’s world-building. If you want to learn about exoplanets or how realistic the anatomy of the movie’s alien animals is, these videos will feed your brain while still providing entertainment value.

Perhaps the most enticing part of Disney’s latest social media collaboration is the opportunity for fans to win prizes and trips. TikTok creators who make edits with the #TikTokAvatarContest hashtag are entered into a competition to win Avatar merchandise. The biggest winners will be able to take a trip to visual effects studio Wētā Workshop in New Zealand or visit Avatar director James Cameron’s Lightstorm Entertainment Studio in Los Angeles.

Avatar: Fire and Ash is the third installment in director Cameron’s cinematic passion project. While the first Avatar movie was released in 2009, Cameron didn’t release another entry in the franchise until 2022. In total, there is a five-movie arc planned for the indigo alien Na’vi on the moon of Pandora.

The Avatar movies are known for pushing the boundaries of CGI visual effects in cinema. They are also historically big winners at the box office: the original Avatar is the highest-grossing film of all time, earning $2.9 billion across its theatrical releases. Its sequel, Avatar: The Way of Water, is the third-highest-grossing film of all time, trailing Avengers: Endgame. You can stream those movies on Disney Plus.

It remains to be seen whether Avatar: Fire and Ash will financially live up to its predecessors. The film currently has mixed reviews from critics on Rotten Tomatoes.

Brain-Inspired Algorithms Could Dramatically Cut AI Energy Use

A new study dives into a major redesign for AI architecture.

One major issue facing artificial intelligence is the interaction between a computer’s memory and its processing capabilities. When an algorithm is in operation, data flows rapidly between these two components. However, AI models rely on a vast amount of data, which creates a bottleneck.

A new study, published on Monday in the journal Frontiers in Science by Purdue University and the Georgia Institute of Technology, suggests a novel approach to building computer architecture for AI models using brain-inspired algorithms. The researchers say that creating algorithms in this manner could reduce the energy costs associated with AI models.

«Language processing models have grown 5,000-fold in size over the last four years,» Kaushik Roy, a Purdue University computer engineering professor and the study’s lead author, said in a statement. «This alarmingly rapid expansion makes it crucial that AI is as efficient as possible. That means fundamentally rethinking how computers are designed.»

Most computers today are modeled on an idea from 1945 called the von Neumann architecture, which separates processing and memory. This is where the slowdown occurs. As more people around the world utilize data-hungry AI models, the distinction between a computer’s processing and memory capacity could become a more significant issue.

Researchers at IBM called out this problem in a post earlier this year. The issue computer engineers are running up against is called the ‘memory wall.’

Breaking the memory wall

The memory wall refers to the disparity between memory and processing capabilities. Essentially, computer memory is struggling to keep up with processing speeds. This isn’t a new issue. A pair of researchers from the University of Virginia coined the term back in the 1990s.

But now that AI is prevalent, the memory wall issue is sucking up time and energy in the underlying computers that make AI models work. The paper’s researchers argue that we could try a new computer architecture that integrates memory and processing.

Inspired by how our brains function, the AI algorithms referred to in the paper are known as spiking neural networks. A common criticism of these algorithms in the past is that they can be slow and inaccurate. However, some computer scientists argue that these algorithms have shown significant improvement over the last few years.

The researchers suggest that AI models should utilize a concept related to SNNs, known as compute-in-memory. This concept is still relatively new in the field of AI.

«CIM offers a promising solution to the memory wall problem by integrating computing capabilities directly into the memory system,» the authors write in the paper’s abstract.

Medical devices, transportation, and drones are a few areas where researchers believe improvements could be made if computer processing and memory were integrated into a single system.

«AI is one of the most transformative technologies of the 21st century. However, to move it out of data centers and into the real world, we need to dramatically reduce its energy use,» Tanvi Sharma, co-author and researcher at Purdue University, said in a statement.

«With less data transfer and more efficient processing, AI can fit into small, affordable devices with batteries that last longer,» Sharma said.
