A Credit Score For Your COVID-19 Risk? USC Gets Federal Funds to Create a Location-Based Mobile App

Researchers at the University of Southern California, Emory University and the University of Texas Health Science Center have received a federal research grant to create a mobile app for contact tracing the novel coronavirus that hopes to track a person's real-time location and symptoms "for quarantine and decontamination." The project would use collected data to calculate a type of credit score of your COVID-19 risk and uses that to help calculate an aggregate risk score for locations like your neighborhood grocery store over time.


As part of the National Science Foundation Rapid Response Research award, created for situations like the ongoing pandemic, USC's Cyrus Shahabi, a professor of computer science, electrical engineering and spatial sciences, and chair of the Computer Science Department was granted $67,185. The project, entitled "REACT, for REAal-time Contact Tracing and risk monitoring via privacy-enhanced tracking of users' locations and symptoms" is a multi-university with researchers at Emory University and the University of Texas Health Science Center, with total funding at $151,477. Work officially begins on Friday.

The universities hope to have a working mobile app by August, in time for the start of the fall semester, Shahabi said.

It's yet another digital twist on contact tracing, a pillar of public health and infectious disease control that can be onerous detective work. It involves identifying those who have been in contact with infected persons to help isolate and limit spread of a virus, especially during epidemic — or, in this case, pandemic conditions.

Enabling such efforts have become a recent focus by governmental entities and organizations. In California, Gov. Gavin Newsom has said that contact tracing capacity and expanded testing are crucial measures that need to be in place before stay-at-home orders can be loosened. That includes establishing a contact tracing "workforce" and developing a statewide training academy to train 10,000 workers to do contact tracing.

Shahabi envisions a use case where people with higher personal risk scores might decide to stay home or get tested for COVID-19, and where areas that are deemed high-risk because people are later known to be infected, like a particular supermarket, might be avoided. Policymakers could warn the public to avoid an area that's known to be a potential hotspot of infection.

The main problem with contact tracing is that it relies on human memory, in this case over as long as a 14-day period, which can be especially faulty, Shahabi said. It also has a built-in delay between when an infected person is identified and when those who have been exposed are notified. Immediate isolation is only possible with digital contact tracing, he said.

A recent Science research report found that SARS-CoV-2, which causes the disease COVID-19, is spreading "too fast to be contained by manual contact tracing, but could be controlled if this process was faster, more efficient and happened at scale" using digital methods like a mobile app.

While companies like Apple and Google who have engaged in a rare collaborative effort to create an "exposure notification API" that would be utilized to inform people via bluetooth signals on their phone that they may have been near an infected person -- allegedly without jeopardizing privacy.

Shahabi said that Apple and Google's proposed method could provide many false positives or negatives, because it doesn't take into account factors like whether a person is wearing a mask or how close they are. For those who are warned, it could be unclear as to what to do about it, and eventually people may become inured to alarm bells that are raised because of it, he said.

Countries such as South Korea or China have used location-based digitized contact tracing. However, it has only been successful because citizens are forced to download it, opt into location monitoring, and regularly check in or otherwise be visited by enforcement authorities, according to Dr. Jeffrey Klausner, a professor of medicine in the division of infectious diseases at the David Geffen School of Medicine at UCLA who has worked in contact notification for 25 years in areas like HIV in the United States.

"In that setting where there's 100% mandated compliance, it's been shown it can work, in our setting in the United States, I don't see that really happening," Klausner said. "We have enough problems with governors issuing orders and denying free personal movement, that the idea that people are going to be ordered to download apps to monitor their movement is highly unlikely and probably not constitutional."

Privacy advocates have repeatedly raised alarms over efforts by governments in China, South Korea, Israel, and other areas in the world to stop the viral spread through surveillance, and have warned about ensuring that any privacy tradeoffs are narrow and time-limited.

"There's several red flags," said Bennett Cyphers, a staff technologist with the Electronic Frontier Foundation, a nonprofit digital rights advocacy group. That includes the fact that GPS, when you're not in an area with tall buildings, provides accurate information roughly down to 15 feet. Precise location data isn't accurate enough to do reliable contact tracing. If people choose to limit the specificity of their location data, then it will be even worse.

"Even if I just stay in my house all day, there are probably hundreds of people within a thousand feet of me that I never interact with," Cyphers said.

Shahabi has repeatedly brought up concerns about privacy implications of the work in an interview with dot.LA and in the grant itself, stating that "such use also heightens concerns on individual privacy and data abuse" and that there needs to be "a careful balance or privacy protection with public health benefits."

The app would enable users to control and refine how frequently their data is captured and how detailed it is, the grant states. The grant would also investigate "privacy-preserving" ways to share collected data for further research studies.

Shahabi would aggregate the risk scores for individuals using AI to calculate risk scores for community areas as part of what he wants to call his pandemic tool kit, or Pandemic Risk Evaluation Platform (PREP). He believes that this aggregation would somewhat alleviate individual privacy concerns for public use of the data by policymakers and others, and is also less potentially problematic than the Apple and Google method.

Cyrus Shahabi, USC professor of computer science, electrical engineering and spatial sciences, and chair of the Computer Science Department.

Shahabi said he is working on getting some raw location data from an outside company to begin doing some risk analysis work.

For privacy advocates like Cyphers, the concern is if user location data is ultimately collected and stored by a single entity, it ups the privacy risk to people who participate. And the privacy risks are still "massive" even with low-resolution data, he said. The data can give a general idea of where a person lives and works, plus when the person arrives there and elsewhere. Such cell-site data is used by police to make cases regularly.

Risk scores could also become problematic if a school or employer requires students or workers reveal them as a condition of receiving a benefit, entering a building or returning to their office, Cyphers said. How the scores are created, whether users are informed about what makes them up, and how they're used are all crucial questions that need to be transparently answered.

"When you introduce 'scoring' that takes other factors into account, it complicates everything, and increases the risk that users will be misinformed or discriminated against due to factors beyond their control," Cyphers said.

In China, the government has used Alipay Health Code, giving citizens a QR code inside the app that's colored red, yellow or green to indicate your health status, with the color green enabling you to travel freely. Law enforcement authorities were involved in the app's development, according to China's state-run media.

Klausner, the epidemiologist, said "we generally feel that voluntary notification where we educate people and empower them with tools to do the notification themselves is the most effective (way) and we've built digital tools for them to use over the past few decades," including a new one that lets you notify people swiftly and directly via text or email immediately and directly.

He added: "It's going to be difficult to get Americans to agree to involuntary surveillance" and to agree to download or opt into such location tracking on a basis large enough to be effective.

Here’s Why Streaming Looks More and More Like Cable

Here’s Why Streaming Looks More and More Like Cable
Evan Xie

The original dream of streaming was all of the content you love, easily accessible on your TV or computer at any time, at a reasonable price. Sadly, Hollywood and Silicon Valley have come together over the last decade or so to recognize that this isn’t really economically viable. Instead, the streaming marketplace is slowly transforming into something approximating Cable Television But Online.

It’s very expensive to make the kinds of shows that generate the kind of enthusiasm and excitement from global audiences that drives the growth of streaming platforms. For every international hit like “Squid Game” or “Money Heist,” Netflix produced dozens of other shows whose titles you have definitely forgotten about.

The marketplace for new TV has become so massively competitive, and the streaming landscape so oversaturated, even relatively popular shows with passionate fanbases that generate real enthusiasm and acclaim from critics often struggle to survive. Disney+ canceled Luscasfilm’s “Willow” after just one season this week, despite being based on a hit Ron Howard film and receiving an 83% critics score on Rotten Tomatoes. Amazon dropped the mystery drama “Three Pines” after one season as well this week, which starred Alfred Molina, also received positive reviews, and is based on a popular series of detective novels.

Even the new season of “The Mandalorian” is off to a sluggish start compared to its previous two Disney+ seasons, and Pedro Pascal is basically the most popular person in America right now.

Now that major players like Netflix, Disney+, and WB Discovery’s HBO Max have entered most of the big international markets, and bombarded consumers there with marketing and promotional efforts, onboarding of new subscribers inevitably has slowed. Combine that with inflation and other economic concerns, and you have a recipe for austerity and belt-tightening among the big streamers that’s virtually guaranteed to turn the smorgasbord of Peak TV into a more conservative a la carte offering. Lots of stuff you like, sure, but in smaller portions.

While Netflix once made its famed billion-dollar mega-deals with top-name creators, now it balks when writer/director Nancy Meyers (“It’s Complicated,” “The Holiday”) asks for $150 million to pay her cast of A-list actors. Her latest romantic comedy will likely move over to Warner Bros., which can open the film in theaters and hopefully recoup Scarlett Johansson and Michael Fassbender’s salaries rather than just spending the money and hoping it lingers longer in the public consciousness than “The Gray Man.”

CNET did the math last month and determined that it’s still cheaper to choose a few subscription streaming services like Netflix and Amazon Prime over a conventional cable TV package by an average of about $30 per month (provided you don’t include the cost of internet service itself). But that means picking and choosing your favorite platforms, as once you start adding all the major offerings out there, the prices add up quickly. (And those are just the biggest services from major Hollywood studios and media companies, let alone smaller, more specialized offerings.) Any kind of cable replacement or live TV streaming platform makes the cost essentially comparable to an old-school cable TV package, around $100 a month or more.

So called FAST, or Free Ad-supported Streaming TV services, have become a popular alternative to paid streaming platforms, with Fox’s Tubi making its first-ever appearance on Nielsen’s monthly platform rankings just last month. (It’s now more popular than the first FAST service to appear on the chart, Paramount Global’s Pluto TV.) According to Nielsen, Tubi now accounts for around 1% of all TV viewing in the US, and its model of 24/7 themed channels supported by semi-frequent ad breaks couldn’t resemble cable television anymore if it tried.

Services like Tubi and Pluto stand to benefit significantly from the new streaming paradigm, and not just from fatigued consumers tired of paying for more content. Cast-off shows and films from bigger streamers like HBO Max often find their way to ad-supported platforms, where they can start bringing in revenue for their original studios and producers. The infamous HBO Max shows like “The Nevers” and “Westworld” that WBD controversially pulled from the HBO Max service can now be found on Tubi or The Roku Channel.

HBO Max’s recently-canceled reality dating series “FBoy Island” has also found a new home, but it’s not on any streaming platform. Season 3 will air on TV’s The CW, along with a new spinoff series called (wait for it) “FGirl Island.” So in at least some ways, “30 Rock” was right: technology really IS cyclical.

As TikTok Faces a Ban, Competitors Prepare to Woo Its User Base

As TikTok Faces a Ban, Competitors Prepare to Woo Its User Base

Another day, another update in the unending saga that is the potential TikTok ban.

The latest: separate from the various bills proposing a ban, the Biden administration has been in talks with TikTok since September to try and find a solution. Now, having thrown its support behind Senator MarkWarner’s bill, the White House is demanding TikTok’s Chinese parent company, ByteDance, sell its stakes in the company to avoid a ban. This would be a major blow to the business, as TikTok alone is worth between $40 billion and $50 billion—a significant portion of ByteDance’s $220 billion value.

Clearly, TikTok faces an uphill battle as its CEO Shou Zi Chew prepares to testify before the House Energy and Commerce Committee next week. But other social media companies are likely looking forward to seeing their primary competitor go—and are positioning themselves as the best replacement for migrating users.

Meta

Last year, The Washington Post reported that Meta paid a consulting firm to plant negative stories about TikTok. Now, Meta is reaping the benefits of TikTok’s downfall, with its shares rising 3% after the White House told TikTok to leave ByteDance. But this initial boost means nothing if the company can’t entice creators and viewers to Instagram and Facebook. And it doesn’t look promising in that regard.

Having waffled between pushing its short-form videos, called Reels, and de-prioritizing them in the algorithm, Instagram announced last week that it would no longer offer monetary bonuses to creators making Reels. This might be because of TikTok’s imminent ban. After all, the program was initially meant to convince TikTok creators to use Instagram—an issue that won’t be as pressing if TikTok users have no choice but to find another platform.

Snap

Alternatively, Snap is doing the opposite and luring creators with an ad revenue-sharing program. First launched in 2022, creators are now actively boasting about big earnings from the program, which provides 50% of ad revenue from videos. Snapchat is clearly still trying to win over users with new tech like its OpenAI chatbot, which it launched last month. But it's best bet to woo the TikTok crowd is through its new Sounds features, which suggest audio for different lenses and will match montage videos to a song’s rhythm. Audio clips are crucial to TikTok’s platform, so focusing on integrating songs into content will likely appeal to users looking to recreate that experience.

YouTube

With its short-form ad revenue-sharing program, YouTube Shorts has already lured over TikTok creators. It's even gotten major stars like Miley Cyrus and Taylor Swift to promote music on Shorts. This is likely where YouTube has the best bet of taking TikTok’s audience. Since TikTok has become deeply intertwined with the music industry, Shorts might be primed to take its spot. And with its new feature that creates compiles all the videos using a specific song, Shorts is likely hoping to capture musicians looking to promote their work.

Triller

The most blatant attempt at seducing TikTok users, however, comes from Triller, which launched a portal for people to move their videos from TikTok to its platform. It’s simple, but likely the most effective tactic—and one that other short-form video platforms should try to replicate. With TikTok users worried about losing their backlog of content, this not only lets users archive but also bolsters Triller’s content offerings. The problem, of course, is that Triller isn’t nearly as well known as the other platforms also trying to capture TikTok users. Still, those who are in the know will likely find this option easier than manually re-uploading content to other sites.

It's likely that many of these platforms will see a momentary boost if the TikTok ban goes through. But all of these companies need to ensure that users coming from TikTok actually stay on their platforms. Considering that they have already been upended by one newcomer when TikTok took over, there’s good reason to believe that a new app could come in and swoop up TikTok’s user base. As of right now, it's unclear who will come out on top. But the true loser is the user who has to adhere to the everyday whims of each of these platforms.
