Tag and Trace: How Blockchain Is Improving Security

14 June, 2022

Blockchain tech is already being used in the food, fashion, and pharmaceutical industries to improve supply chains and its potential doesn’t end there.

Blockchain is changing the game and a wealth of industries are already utilizing its track and trace capabilities to enhance efficiencies. Companies including Walmart, Microsoft, and Amazon are currently exploring blockchain applications, and investment in the nascent technology is growing steadily.

Read on to discover the main industries taking notice of blockchain, as well as how LOX is set to use blockchain and microdot technology to better track and trace wireless devices. 

The food industry 

Back in 2018, Walmart leveraged blockchain to increase the safety of its food supply. Now, Walmart has an automated system for managing invoices and payments, with the ability to track over 500 food items from farm to store. This lets retailers determine exactly which batch of products to recall when an issue appears. It’s predicted that lots of food companies will begin to utilize blockchain technology in the near future, with major retailers Sainsbury’s, Co-op, and Nestlé all running blockchain trials and initiatives over the past 18 months.

The fashion industry

The clothing supply chain is complicated, often spanning many countries and multiple factories. Blockchain has the potential to allow supply chains to be managed and tracked, as well as keep manufacturers in the loop with timings and cost projections. 

The counterfeit fashion industry is worth over a billion dollars and can reduce the value of designer fashion brands. By using blockchain for tracking and tracing goods and products, fashion brands can register their clothing, which makes counterfeiting almost impossible. Burberry has taken the first step in investing in blockchain technology, asking IBM interns to create a prototype blockchain-based protocol late last year. 

The pharmaceutical industry 

Pharmaceuticals are also interested in blockchain technology and its ability to track and trace products. Similar to the food and fashion industries, pharmaceutical companies are looking to utilize the blockchain to record and create an audit trail for drugs from production to purchase. Pharmaceutical giants including Quest Diagnostics and Pfitzer are currently exploring blockchain tech for this purpose.

Nano security tagging to improve wireless device security and traceability

Similarly to how blockchain has aided the food, fashion, and pharmaceutical industries, it can also revolutionize wireless device security. Currently, phone security relies on three factors: 

IMEI. All mobile phones are identified through their unique International Mobile Equipment Identity (IMEI) number. When reporting a phone as lost or stolen to your cell phone carrier, they use your IMEI number to block your phone from their mobile network—this is what’s known as IMEI blacklisting. 

Serial Numbers. A serial number is a unique number assigned by the manufacturer to identify an individual device, like a phone, tablet, or TV. For example, your phone’s serial number will be unique to every other phone made from the same manufacturer. The serial number makes it simpler to organize and keep track of your device. 

IP Address. An IP address stands for “Internet Protocol” and it’s a unique address that identifies a device on the Internet. It acts as an identifier that allows information to be sent between devices on a network, containing location information and making devices accessible for communication. 

In its present state, there are significant security issues with the current identifier model. For one, many wireless items—including smartwatches, speakers, and home pods—do not contain identifying data and are vulnerable to theft and loss. What’s more, despite being able to identify and blacklist some wireless devices, it’s still relatively difficult to retrieve them once lost or stolen. 

This is where LOX’s innovative Nano Security Tagging technology comes in.

LOX’s Security Tagging technology

Nano Security Tagging is an invisible method for tagging and tracing items using Microdot Technology. This involves attaching Microdots onto your devices to provide a unique identifier that registers an item to its owner.

Impressively, Microdots are not visible to the naked eye, and criminals are unaware that the stolen device is being tracked and traced. By tagging your wireless devices with Microdots, then registering them on the LOX Network your undisputed ownership of an item is publicly claimable. This also makes returning lost and stolen wireless devices far easier than under the previous security model, as it’s always traced back to you.  

Transforming wireless device security with LOX Nano Security Tagging

There are significant issues with the current methods of tracking and tracing wireless devices. However, by introducing Nano Security Tagging, devices can be better tracked and traced. This makes it more likely for owners to be reunited with their devices, as well as making it more difficult for criminals to successfully resell stolen devices.
