Le problème de la #surveillancepricing a touché #SNCF @groupeSNCF
Hier, j'ai consulté le site web de SNCF : le billet de train coûtait 44 €.
Aujourd'hui, je suis retourné sur le même site, le prix avait doublé à 88 €.
J'ai essayé d'effacer les cookies, même prix. J'ai essayé d'utiliser un VPN, même prix.
J'ai essayé un autre navigateur web, et le prix est redescendu à 44 €. Ils utilisent donc l'empreinte digitale du navigateur pour augmenter dynamiquement les prix.
Surveillance pricing is different. Where dynamic pricing responds to market conditions, surveillance pricing responds to the individual. It draws on browsing history, device, postal code, purchase frequency and inferred income to predict a person’s willingness to pay.
"Parliament voted down a motion on April 15 to ban a practice most Canadians have never heard of, but that retailers are already rolling out: surveillance pricing.
"Also called algorithmic personalized pricing, the practice uses personal data to estimate how much consumers are willing to pay, then adjusts the price accordingly. Two shoppers, same store, same item: two different prices, generated by data neither of them can see."

Dynamic pricing seems to ask: “What are the conditions right now?” Surveillance pricing asks: “Who are you, and how much can we extract from you?”

I feel like this piece in @thetyee is close to @pluralistic 's heart
#Maryland Is First to Ban #AI #Grocery #PriceGauging
A #state #law that goes into effect in October prohibits grocery stores & third-party delivery services from using consumer data to boost #prices.
The practice — supported by #ArtificialIntelligence & known as #DynamicPricing or #SurveillancePricing — can lead to 2 consumers paying different amounts for the same item from the same retailer, at roughly the same time.

How surveillance pricing raises the prices for all of us.
Just received you pay-check? Breakfast can be more expensive.
A health problem or urgent travel requirement? Up goes the price for medicines or travel.
They analyse your needs and profit accordingly.

If you want to piss me off, it's easy: just breezily assert that our tech regulation problems are the result of the fast pace of technological change racing ahead of the plodding speed of governmental action:pluralistic.net/2026/04/22/ube…
