US scientists develop edible security tags to thwart drug counterfeiters

edible security tags

Researchers at Purdue University have created a small edible tag that can be embedded into medicines in order to prevent the counterfeiting of drugs.

In a paper published in the journal Nature Communications, scientists from the institution explain that drug counterfeiters would need to decipher complicated patterns not fully visible to the naked eye to get round the new security system.

The edible tags serve as digital fingerprints for individual pills and capsules, and are intended to help pharmacists verify the legitimacy of their stock before dispensing it to patients as well as being a method to discourage the counterfeiting of medicines.

According to the researchers, their invention uses an authentication technique called physical unclonable functions (PUF) that generate a different response each time they are stimulated, meaning that even drug manufacturers would not be able to recreate tags.

Taking the form of a transparent film made of silk and fluorescent proteins, the tags are easily digestible, meaning they can be consumed by patients when they take their mediation.

Commenting on the new technology, Jung Woo Leem, a postdoctoral associate in biomedical engineering at Purdue, said in a statement: “Our concept is to use a smartphone to shine an LED light on the tag and take a picture of it. The app then identifies if the medicine is genuine or fake.”

The tags currently last for at least two months before the proteins start to degrade, but Leem and his team are working on extending their life so as they can last until the expiry date of the drugs they are intended to protect.

As well as holding a security key that can verify the authenticity of medication, the tags could also hold other information, such as dosage instructions.

Leem has made two patent applications to protect the tags through the Purdue Research Foundation Office of Technology Commercialisation.

According to a report published by the World Health Organisation (WHO) in November 2017, 10% of all pharmaceutical products circulating in low and middle-income countries at that time were either fake or of substandard quality.

The WHO said the trade in illicit pharmaceuticals is controlled by major organised crime networks who often channel their profits into other forms of illicit activity.

In March of last year, Europol revealed that a crackdown it had led on the sale of illicit pharmaceuticals across 16 countries in 2018 resulted in the seizure of some 13 million doses of counterfeit or smuggled medicines.

Crooked vendors exploiting flaw in eBay’s feedback system to con buyers into purchasing bogus and dangerous items

crooked vendors exploiting flaw in eBay’s feedback system

Buyers on eBay are being duped into purchasing substandard and counterfeit products due to a flaw in the online auction platform’s seller feedback system, according to an investigation conducted by UK consumer group Which?

The watchdog found that dishonest vendors can take advantage of these flaws by linking positive reviews of genuine products manufactured by companies such as Apple and Samsung to fake and low-quality items.

Which? found that crooked sellers are able to link thousands of positive reviews to eBay listings they have nothing to do with.

The organisation discovered that real reviews can be associated with fake products that are potentially dangerous, such as counterfeit mobile phone chargers that can pose a fire risk.

Sellers are able to do this by using “product IDs” associated with genuine items when adding their products to eBay, subsequently benefitting from the positive reviews those items have attracted.

The system is intended to make the process of listing products on eBay quicker and easier by allowing sellers to pull information from similar items that have a linked product ID.

As part of its investigation, Which? purchased 20 bogus Apple and Samsung accessories such as chargers and USB cables that were supposed to be official and shared the same reviews as products manufactured by the two technology firms

Calling for online ecommerce platforms to be held accountable for flaws in their seller feedback systems that allow dishonest vendors to pull the wool over buyers’ eyes, Head of Home Products and Services at Which? Natalie Hitchins said: “Our investigation has uncovered yet another example of online reviews being manipulated to mislead people.

“eBay’s product review system is confusing for consumers and could even direct them towards counterfeit or dangerous products sold by unscrupulous sellers.

“Online reviews influence billions of pounds of consumer spending each year.

“The [UK Competition and Markets Authority] must now investigate how fake and misleading reviews are duping online shoppers, taking the strongest possible action against sites that fail to tackle the problem.”

Responding to the findings of Which?’s investigation eBay said in a statement: “The research does not fully consider that there are distinctions between product reviews (which provide buyers with a holistic review of the same product), and seller feedback (which can be used to see specific reviews of a seller’s performance and may reflect the item’s condition).”

Earlier this month, Bloomberg reported that US politicians had called on lawmakers to hold ecommerce companies such as eBay and Amazon to account if they fail to prevent third-party vendors selling counterfeit or substandard products on their platforms.

Major ‘lover boy’ prostitution gang broken up by coalition of European law enforcement agencies

major ‘lover boy’ prostitution gang

A Romanian human trafficking and prostitution network that used the “lover boy” method to entrap young women before forcing them into sex work has been broken up a coalition of European law enforcement agencies.

The lover boy method, also known as the “Romeo pimp” method, involves young men seducing victims with the objective of coercing them into prostitution.

Lover boy traffickers groom their victims to believe they have entered into a serious romantic relationship before using emotional, psychological and sometimes physical abuse to intimidate them into working in the sex services industry.

Investigators from Spain, Romania, the Czech Republic and several other European nations were involved in the operation that resulted in the dismantling of the gang, which is said to have groomed and exploited at least 10 young women by forcing them to work as prostitutes.

The operation resulted in the arrest of 14 people in Romania and Spain, the safeguarding of 10 trafficking victims, and the confiscation of a number of items, including a quantity of cash, jewellery, expensive vehicles and several electronic devices.

In total, the agencies taking part in the effort raided 16 properties in the Czech Republic, Romania and Spain.

Having groomed their victims, Romanian members of the network would develop manipulative dependent relationships with the young women they targeted before forcing them into sex work.

Once under the traffickers’ control, victims would be abused and drugged before being sold onto other members of the network for as much as €6,000 ($6,632) each.

The women would then be moved between locations and countries on a regular basis as part of the gang’s efforts to avoid the attention of police.

Profits made by the network were laundered through the purchase of property, expensive jewellery and high-value cars.

Ongoing investigations into the network’s activities are focussed on the theory that it was working in cooperation with another gang.

Enquires have already resulted in the identification of more than 40 additional women who fell victim to the two criminal organisations.

In a statement, Europol said: “Europol facilitated the information exchange between the participating countries, provided coordination support and analysed operational information against Europol’s databases to give leads to investigators.

“Europol conducted a financial analysis based on the information provided which highlighted the extension of the criminal activity of the group and the presence and flow of illicit profits to other jurisdictions.”

Taking cocaine will not cure people struck down with the coronavirus, French government warns public

taking cocaine will not cure people infected with coronavirus

Authorities in France have been forced to inform the public that taking cocaine will not cure people infected with the coronavirus.

Taking to Twitter on Sunday, the French Ministry for Solidarity and Health told its followers that cocaine is not only ineffective when it comes to fighting the coronavirus, but is also a highly addictive drug that can cause serious harm to users’ health.

The government department was seeking to counter fake news circulating on social media that taking the drug could cure or prevent the virus, including doctored news stories that appeared to confirm the drug’s effectiveness at fighting the disease.

The ministry’s Twitter post included a link to a government information page that provided further guidance on disinformation circulating about the coronavirus outbreak.

As well as encouraging those worried about the coronavirus to start taking cocaine, online trolls have also suggested that bleach can also help fight the disease.

In a post on Twitter that has attracted many thousands of engagements, @Jordan_Sather_ told his followers: “Would you look at that. Not only is chlorine dioxide (aka ‘MMS’) an effective cancer cell killer, it can wipe out coronavirus too.

“No wonder YouTube has been censoring basically every single video where I discuss it over the last year.”

In August of 2019, the US Food and Drug Administration issued a warning about that dangers of consuming bleach, noting: “Drinking any… chlorine dioxide products can cause nausea, vomiting, diarrhoea, and symptoms of severe dehydration.”

As well as warning about cocaine’s inability to fight the coronavirus, the French government has also told members of the public that spraying bleach or alcohol on their bodies will not neutralise viruses they have already been infected with.

Elsewhere, US Vodka maker Tito’s Homemade was last week forced to urge people not to make DIY hand sanitiser out of its products.

Responding to one of its customers who said they had done just that, the company said on Twitter: “Per the CDC [Centres for Disease Control and Prevention], hand sanitizer needs to contain at least 60% alcohol. Tito’s Handmade Vodka is 40% alcohol, and therefore does not meet the current recommendation of the CDC. Please see attached for more information.”

For its part, the World Health Organisation, which today officially categorised the coronavirus as a pandemic, has published a webpage dispelling misinformation about the disease, noting that the virus cannot be killed of avoided by taking a hot bath or using hand dryers.
