As technology progresses, and sentiments against invasive techs grow, the tech community, together with the academe, has been developing new alternatives to existing systems that are more palatable to the people. One example of this technology is the latest AI trained in China that can detect and survey people just by using echolocation.
A Chinese researcher has found a way to balance security and privacy through artificial intelligence that can allow computers to echolocate. By training AI to sift through signals from arrays of acoustic sensors, the system can gradually learn to parse your movements—standing, sitting, falling—using only ultrasonic sound.
According to Dr. Xinhua Guo at the Wuhan University of Technology, the newly developed system can be more palatable to privacy advocates, as it is not as invasive as cameras or facial recognition software. As artificial intelligence relies on echolocation and ultrasonic sounds, similar to the technology that allows people to navigate in the dark, it does not invade privacy since it does not record any video or audio. This means that it only tracks motion and not the person per se.
“Human activity recognition is widely used in many fields, such as the monitoring of smart homes, fire detecting and rescuing, hospital patient management, etc. Acoustic waves are an effective method for human activity recognition,” Dr. Xinhua Guo wrote in his study.
“In traditional ways, one or a few ultrasonic sensors are used to receive signals, which require many feature quantities of extraction from the received data to improve recognition accuracy.”
The system uses a two-dimensional acoustic array and convolutional neural networks. A single feature quantity is utilized to characterize the sound of human activities and identify those activities.
For those who are adamant about the accuracy of the system, the results of the tests conducted by the researcher show 97.5% for time-domain data and 100% for frequency-domain data. This level of accuracy surmounts the accuracy rate of using facial recognition software. Aside from facial recognition, the new system was said to outperform other motion tracking technologies like k-nearest neighbor and support vector machines.
However, Guo admits that the system can better identify static motions such as sitting or standing still rather than movements per se. This is expected, explained the authors, because falling and walking introduce individual differences in how people move, making it harder for computers to figure out a general acoustic pattern. But with future studies, the researcher aims to resolve this gap in his development.
It could potentially be used in many applications
As the new system could improve over time through further research, it could be used in a plethora of different applications from health, to home security, to law enforcement operations. The system could allow caretakers to monitor elderly folks who live alone for falls inside their house or track patient safety inside hospital rooms.
The possibility and the potential for this system are endless. It could be installed in public spaces to monitor motions in trains, sidewalks, and public utility vehicles to guard people against sexual harassment or violence similar to how satellites are used to capture heat images of the sea to patrol for sunken ships, maritime collision, and other nautical incidents.
However, since the system only records motion, there is no potential for identification – unlike facial recognition and surveillance cameras. A feature that experts believe could be the perfect balance between safety and privacy in technology. The system doesn’t even generate blob-like body shapes that grace US airports’ body camera screens.
The clamor against facial recognition
This could be good news for privacy advocates and people in general. Clamor has since been loud regarding the potential for privacy violations by facial recognition software. And the scientific community is in tune with advocates in saying that facial recognition technology is a juvenile technology that needs regulation as it tramples the rights of people to privacy.
Only recently, reports reveal that law enforcement agencies have been using facial recognition technologies to solve crimes – sometimes in creative ways. A police station has been feeding images of celebrities who they think could look like their suspect. And arrests have been made. But it seems like this strategy is only accurate less than half the time; which lead to incidents of wrongful detention in many cases.
Because of the intensifying opposition of the scientific community and people in general of facial recognition technology, San Francisco became the first city to outlaw the use of facial recognition techs in police operations and by other city agencies to serve as a model for other cities to follow through.
Lenovo Patches Security Flaw Exposing 36TB Of Financial Data In The Wild
The compromised data include sensitive financial information like card numbers and financial records.
A recent breach that has exposed more than 36TB of data owned by users of specific network-attached storage devices has been confirmed by the computer tech giant, Lenovo, and said that a vulnerability in some of their products “could allow an unauthenticated user to access files on NAS shares via the API.”
Security researchers from Vertical Structures, who made the discovery, said that they found “about 13,000 spreadsheet files indexed, with 36 terabytes of data available. The number of files in the index from scanning totaled to 3,030,106.” Worse, these data include sensitive financial information like card numbers and financial records.
According to a security notification from Lenovo, the breach affected both Iomega and LenovoEMC NAS products. Vertical Structures was able to track down the source, a legacy Iomega storage product acquired by EMC and co-branded Lenovo-EMC in a joint venture. They added that it is “trivially easy” to exploit that application programming interface (API) and allow attackers to access the data stored upon any of several Lenovo-EMC network-attached storage (NAS) devices.
Discovery was verified by WhiteHat Security
Researchers from Vertical Structures said they commissioned the help of WhiteHat Security, a security firm known to have patched up network-related vulnerabilities in the past, to verify their discovery because “of its world-renowned reputation in helping secure applications, to work together to verify the vulnerability found.”
“Verifying vulnerabilities is a very important step in securing applications, networks, and devices. After all, on an average day, WhiteHat scanners discover hundreds upon hundreds of new potential vulnerabilities,” they added.
After the team has notified Lenovo of their discovery of the said vulnerability, they said that the company swiftly responded and took measures to mitigate the impacts of the vulnerability.
When asked for comments regarding the problem, Simon Whittaker, cybersecurity director at Vertical Structures, said that “this is definitely a huge problem but one which we see every day.”
“Many organizations fear change and are cautious about retiring old devices. If they can’t replace devices, then they should be using threat modeling techniques to consider how better to protect them and ideally removing them from internet access completely,” he added.
In order to let their users utilize their services, Lenovo pulled three of its old versions out of retirement and brought them back to life while they are patching the said vulnerability. Lenovo then pulled old software from version control to investigate any other potential vulnerabilities to fix and release updates.
“High” severity problem
In a security advisory that Lenovo released, they said that vulnerability has “high” severity and they advised their users to “update to the firmware level (or later) described for your system in the Product Impact section,” and if update is not feasible, “partial protection can be achieved by removing any public shares and using the device only on trusted networks.”
In the advisory, Lenovo lists the products that were impacted by the said flaw. They include:
- px12-350r and ix12-300r, version 184.108.40.206808
- HMND (Home Media Network Hard Drive) Cloud Edition, version 220.127.116.11221
- StorCenter ix2-200, Cloud Edition, version 18.104.22.168221 StorCenter ix4-200d, Cloud Edition, version 22.214.171.124221 StorCenter ix2-200, version 126.96.36.199227
- StorCenter ix4-200d, version 188.8.131.52227
- StorCenter ix4-200rl, version 184.108.40.206227
For their security advisory, Lenovo disclaims that “the information provided in this advisory is provided on an “as is” basis without any warranty or guarantee of any kind” and advised users to “please remain current with updates and advisories from Lenovo regarding your equipment and software” for more recent and updated information about the problem.
As part of their report, Verticle Structures said that there are a lot of things tech companies can learn from what happened in Lenovo. They characterized Lenovo’s approach to the problem as “professional” and hoped that other companies experiencing similar problems could learn from them.
“Not only did they have a clearly stated vulnerability disclosure policy on their site with contact information, but they responded quickly and worked with WhiteHat and Vertical Structure to understand the nature of the problem and quickly resolve it,” said Vertical Structures.
“In sharing this story, both WhiteHat and Vertical Structure hope companies are inspired to always keep cybersecurity top of mind to keep up with the constant barrage of new vulnerabilities and exposures,” they added.
This Free Service Detects And Blocks Suspicious Behaviors Of Android Apps
This service is still on the beta phase but they promise to release improvements and expand their territorial reach.
As a smartphone owner, you can have a plethora of apps available for download via Google Play Store or Apple App Store. However, not all of these apps are secured and are safe to be installed on your devices. Some of them are either fake apps posing as a legitimate version of another app, or worse; they could be carriers of infectious malware that could potentially put your device or yourself in harm’s way.
Amid the risk of threat actors and hackers invading someone’s phone or tablet, leading tech company, Upstream, launched an online index that screens, catalogs, and blocks suspicious Android apps in the market around the world.
“The information on the Secure-D Index, currently in beta, allows anyone to easily find what apps pose a threat to their privacy and pocket, in one place, for free. Data is openly available to the whole mobile industry, from app developers, ad networks and publishers, to media, advertisers and mobile network operators that all fall prey to mobile ad fraud.”
The Secure-D Index is still in beta and is currently being tested. Nonetheless, the company and the platform promise to help resolve the problem of malicious apps that serve as a trojan horse for a more significant and more destructive attack against people’s privacy.
Currently, the platform included an aggregate list of suspected malicious Android Apps, and the index is growing every day as the platform continue to scan the internet to flag these unwanted applications. For each app, the Secure-D Index center features pertinent information such as the number of downloads, market infection rate, and markets where the app is active.
The data is available to 17 regions, and they are working on expanding their reach shortly. They are available in countries like the US, Russia, India, Germany, South Africa, and Egypt, covering up to 1.3 billion mobile data subscribers.
The number of the listed apps in the platform is currently at 1,500, with malicious apps estimating to 13.5 billion downloads. The platform allows users to check whether the apps are available on Google Play, have been removed from Google Play, or are distributed through third-party app stores.
Furthermore, along with the entry of each malicious app, the index also includes data such as the developer’s website, whenever the information is available.
“Secure-D leads the fight against malware, an ever-growing threat for mobile security worldwide. We believe a crucial part of this fight is awareness, which mobile users and, surprisingly, a large part of the industry lacks,” Dimitris Maniatis, Head of Secure-D at Upstream said
“At Upstream, we have been steadily and openly sharing Secure-D’s proprietary findings on suspicious and fraudulent apps in an effort to eliminate digital mobile fraud. The publication of these findings through our Secure-D Index highlights the level of awareness we aim to achieve and the transparency we believe is required to more effectively target the shady practices of threat actors that prey on a whole ecosystem.”
The platform is available for everyone where the Index is available, and it is free of charge, according to the press release of the company. Users can access the top 20 most active malware from the previous day and register for free to access full data — either global or country-specific — see historical data, or search for a specific app.
In 2018 alone, Secure-D having processed over 1.8 billion mobile transactions, detected and blocked over 63,000 malicious apps in 16 countries. They added that the platform is currently processing and blocking an average of 170 malicious applications every day.
Earlier this year, Secure-D reported on the suspicious background activity of 4shared, a popular file-sharing app, Vidmate, a video downloader, and Weather Forecast a preinstalled app on Alcatel devices. They said that all these apps were previously available at Google Play Store and had more than 600,000 downloads before their platform was able to flag their suspicious behavior. The company said that in these three cases alone, Secure-D detected and blocked near 250 million suspicious mobile transactions
“By providing information on suspicious apps freely to the public via Secure-D Index, Upstream aims to further protect mobile subscribers, operators, and advertisers from the ever-growing threat of mobile ad fraud, whose value is currently estimated at $40 billion,” they added.
‘User Data Are Not Transferred To Russia,’ Says FaceApp
The popular photo-manipulation app, Face App, has taken social media platforms like Facebook, Twitter, and Instagram by storm. And with “by storm,” it means that a lot of people, including celebrities and famous individuals, have jumped on the bandwagon to see how they would look like when they grow old.
There are a lot of things interesting about the app; it can manipulate a photo that a user submits to make a realistic version of the picture as the face ages. There is no surprise as to why Face App has gained popularity among young users around the world.
There is a problem though: you need to submit your photo to the app. This means that providing the chosen selfie, FaceApp will have access to your photo at their disposal. That’s why concerns were raised by security experts and data privacy advocates regarding the implication of sending a photo to an app.
One thing that concerns advocate and experts the most is the fact that the company that built and developed the app is from Russia. It is owned by a Russian company named Wireless Labs and has been downloaded by more than 100 million people via Google Play on the Android platform, and by over 50 million people across other platforms including Apple’s iOS.
The Russia issue
Many advocates have cited the human rights record of Russia, as well as the heightened citizen surveillance they have in their country. The fears of advocates and experts are amplified after the privacy terms and conditions for the app reveals that it sneakily includes a clause that would “grant FaceApp a perpetual, irrevocable, nonexclusive, royalty-free, worldwide, fully-paid, transferable sub-licensable license to use, reproduce, modify, adapt, publish, translate, create derivative works from, distribute, publicly perform and display your User Content and any name, username or likeness provided in connection with your User Content in all media formats and channels now known or later developed, without compensation to you [the user or the owner of the photo].”
The polarizing opinions about FaceApp have opened the discussion on how people are carelessly sharing their photos on social media platforms and smartphone apps without a thorough understanding of the implications of such action. In an article published by Wired, they said that what FaceApp is doing is rather common than new.
They said that the same thing is happening when someone uploads a photo on Facebook and Instagram. Instead of demonizing FaceApp and singling it out, the article encourages users to be more vigilant with the data they share across all platforms.
However, security experts and advocates still press on the idea that FaceApp could be used by the Russian government in its surveillance and technology-versus-people agenda. However, FaceApp is strong in its position that it is protecting the privacy of their users, saying that they “perform[s] most of the photo processing in the cloud. We only upload a photo selected by a user for editing. We never transfer any other images from the phone to the cloud.”
“We might store an uploaded photo in the cloud. The main reason for that is performance and traffic: we want to make sure that the user doesn’t upload the photo repeatedly for every edit operation. Most images are deleted from our servers within 48 hours from the upload date. We don’t sell or share any user data with any third parties,” they added.
They also countered the claims that they can be used as Russia’s trojan horse and said that “even though the core R&D team is located in Russia, the user data is not transferred to Russia.”
Furthermore, they clarified that they don’t require users to log in their app for them to use it and while they ask for device permission to access the phone’s camera and photo roll, they only access those that are selected by the users for editing.
“You can quickly check this with any of network sniffing tools available on the internet,” they said.
