Diageo Launches AI Authentication Seal to Combat Counterfeit Spirits in Brazil

Diageo, the owner of brands such as Johnnie Walker and Smirnoff, has introduced a digital authentication seal called Selo Drink Seguro to combat the counterfeiting of distilled spirits in Brazil. Developed in partnership with Securetrace, the technology allows consumers to use a smartphone camera to scan a seal on the bottle. An artificial intelligence system then analyzes a unique microscopic fingerprint to verify the product's authenticity. According to Securetrace, the technology uses the same security standards found in the Brazilian passport and the 100 reais banknote, offering over 27 trillion possible combinations and a 99.99 percent success rate in preventing copies.

The initiative follows a public health crisis in 2025 involving methanol poisoning from adulterated drinks. Ministry of Health data indicates that 73 people were intoxicated and 25 died during that period. Additional cases have been reported in 2026, with 17 confirmed and 23 under investigation between January and August. The seal is currently being implemented across 49 items, including whiskies, vodkas, gins, tequilas, and liqueurs, though it excludes Ypióca and ready to drink products like Smirnoff Ice.

Paula Lindenberg, CEO of Diageo in Brazil, stated that while the technology aims to restore consumer confidence, it cannot stop counterfeiting alone. She called for stronger laws and joint action with public authorities to criminalize falsification. A study by Euromonitor International, commissioned by the Brazilian Distilled Beverages Association (ABBD), estimates that counterfeiting accounts for 4.7 percent of the total distilled spirits market in Brazil.

Outlets with a center lean framed the story as a corporate investment in technology and a call for legislative reform. In contrast, center left outlets emphasized the event as a direct response to a severe public health crisis and a failure of safety that necessitated industry action.
