Genetic Surveillance based on Stray DNA

Leave a reply

Everywhere they go, humans leave stray DNA. Police have used genetic sequences retrieved from cigarette butts and coffee cups to identify suspects; archaeologists have sifted DNA from cave dirt to identify ancient humans. But for scientists aiming to capture genetic information not about people, but about animals, plants, and microbes, the ubiquity of human DNA and the ability of even partial sequences to reveal information most people would want to keep private is a growing problem, researchers from two disparate fields warn this week. Both groups are calling for safeguards to prevent misuse of such human genomic “bycatch.”

Genetic sequences recovered from water, soil, and even air can reveal plant and animal diversity, identify pathogens, and trace past environments, sparking a boom in studies of this environmental DNA (eDNA). But the samples can also contain significant amounts of human genes, researchers report today in Nature Ecology & Evolution. In some cases, the DNA traces were enough to determine the sex and likely ancestry of the people who shed them, raising ethical alarms…Similarly, scientists have for decades analyzed the genetic information in fecal matter to reveal the microbes in people’s intestines—the gut microbiome, which plays dramatic roles in human health and development.

The power to extract personal data from eDNA and microbiome samples will continue to increase, both groups of authors warn. That raises concerns about misuse by police or other government agencies, collection by commercial companies, or even mass genetic surveillance, says Natalie Ram, a law and bioethics scholar at the University of Maryland Francis King Carey School of Law. In the United States, she says, researchers and funding agencies should make greater use of federal Certificates of Confidentiality. They prohibit the disclosure of “identifiable, sensitive research information” to anyone not connected with a study, such as law enforcement, without the subject’s consent….

“Which companies and governments are going to pay and license to have poop-based surveillance technology?” he asks. “Imputing people’s identity based on their poop is compelling and interesting, for a number of reasons, and most of them are all the wrong reasons.”

Tesla as Catfish: When China Carps-Tech CEOs Fall in Line

Leave a reply

Many countries are wrestling with how to regulate digital records. Some economies, including in Europe, emphasize the need for data privacy, while others, such as China and Russia, put greater focus on government control. The U.S. currently doesn’t have a single federal-level law on data protection or security; instead, the Federal Trade Commission is broadly empowered to protect consumers from unfair or deceptive data practices.

Behind China’s moves is a growing sense among leaders that data accumulated by the private sector should in essence be considered a national asset, which can be tapped or restricted according to the state’s needs, according to the people involved in policy-making. Those needs include managing financial risks, tracking virus outbreaks, supporting state economic priorities or conducting surveillance of criminals and political opponents. Officials also worry companies could share data with foreign business partners, undermining national security.


Beijing’s latest economic blueprint for the next five years, released in March 2021, emphasized the need to strengthen government sway over private firms’ data—the first time a five-year plan has done so. A key element of Beijing’s push is a pair of laws, one passed in June 2021, the Data Security Law,  and the other a proposal updated by China’s legislature in Apr0il 2021. Together, they will subject almost all data-related activities to government oversight, including their collection, storage, use and transmission. The legislation builds on the 2017 Cybersecurity Law that started tightening control of data flows.

The law will “clearly implement a more stringent management system for data related to national security, the lifeline of the national economy, people’s livelihood and major public interests,” said a spokesman for the National People’s Congress, the legislature. The proposed Personal Information Protection Law, modeled on the European Union’s data-protection regulation, seeks to limit the types of data that private-sector firms can collect. Unlike the EU rules, the Chinese version lacks restrictions on government entities when it comes to gathering information on people’s call logs, contact lists, location and other data.

In late May 2021, citing concerns over user privacy, the Cyberspace Administration of China singled out 105 apps—including ByteDance’s video-sharing service Douyin and Microsoft Corp.’s Bing search engine and LinkedIn service—for excessively collecting and illegally accessing users’ personal information. The government gave the companies named 15 days to fix the problems or face legal consequences….

Beijing’s pressure on foreign firms to fall in line picked up with the 2017 Cybersecurity Law, which included a provision calling for companies to store their data on Chinese soil. That requirement, at least initially, was largely limited to companies deemed “critical infrastructure providers,” a loosely defined category that has included foreign banks and tech firms….Since 2021, Chinese regulators have formally made the data-localization requirement a prerequisite for foreign financial institutions trying to get a foothold in China. Citigroup Inc. and BlackRock Inc. are among the U.S. firms that have so far agreed to the rule and won licenses to start wholly-owned businesses in China…

Senior officials have publicly likened Tesla to a “catfish” rather than a “shark,” saying the company could uplift the auto sector the way working with Apple and Motorola Mobility LLC helped elevate China’s smartphone and telecommunications industries. To ensure Tesla doesn’t become a security risk, China’s Cyberspace Administration recently issued a draft rule that would forbid electric-car makers from transferring outside China any information collected from users on China’s roads and highways. It also restricted the use of Tesla cars by military personnel and staff of some state-owned companies amid concerns that the vehicles’ cameras could send information about government facilities to the U.S. In late May 2021, Tesla confirmed it had set up a data center in China and would domestically store data from cars it sold in the country. It said it joined other Chinese companies, including Alibaba and Baidu Inc., in the discussion of the draft rules arranged by the CyberSecurity Association of China, which reports to the Cyberspace Administration…

Increasingly, China’s president, Mr. Xi, leaned toward voices advocating greater digital control. He now labels big data as another essential element of China’s economy, on par with land, labor and capital.  “From the point of view of the state, anti-data monopoly must be strengthened,” said Li Lihui, a former president of state-owned Bank of China Ltd. and now a member of China’s legislature. He said he expects China to establish a “centralized and unified public database” to underpin its digital economy.

Genomic Surveillance

Leave a reply

The use of DNA profiling for individual cases of law enforcement has helped to identify suspects and to exonerate the innocent. But retaining genetic materials in the form of national DNA databases, which have proliferated globally in the past two decades, raises important human rights questions.

Privacy rights are fundamental human rights. Around the world, the unregulated collection, use, and retention of DNA has become a form of genomic surveillance. Kuwait passed a now-repealed law mandating the DNA profiling of the entire population. In China, the police systematically collected blood samples from the Xinjiang population under the guise of a health program, and the authorities are working to establish a Y-chromosome DNA database covering the country’s male population. Thailand authorities are establishing a targeted genetic database of Muslim minorities. Under policies set by the previous administration, the U.S. government has been indiscriminately collecting the genetic materials of migrants, including refugees, at the Mexican border.

Governments should reform surveillance laws and draft comprehensive privacy protections that tightly regulate the collection, use, and retention of DNA and other biometric identifiers .They should ban such activities when they do not meet international human rights standards of lawfulness, proportionality, and necessity.
