Sony has filed a patent that could change how competitive games deal with smurfing on PS6 — the practice of experienced players using secondary accounts to face lower-ranked opponents. The document, filed in April 2025 and published on November 5, 2026, describes a system that identifies a player by how they play, not by the account name.
How detection works
The idea is to treat controller habits as a kind of fingerprint. The system collects interaction data — which buttons are pressed, for how long, the interval between presses, and even how the player navigates menus — and uses an artificial intelligence model to compare these patterns with those of other accounts. When the similarity passes a set threshold, the system issues an alert indicating that the two accounts probably belong to the same person.
According to the patent description, the alert can be sent to the platform or to the game's developer, which would then have the option to restrict the secondary account's access to ranked matches or even ban the account. The system could also estimate a player's real skill level from just a few matches.
Risks and limits
There are important caveats. The patent provides no accuracy figures, and a misidentification could flag, for example, a sibling who used the same controller or a friend who tried the console. The document mentions storing data in region-specific databases to comply with privacy rules, but says little about consent. In addition, the examiner's first review rejected the claims as filed — something considered routine at this stage, usually followed by amendments.
A patent is not a confirmation
And, like any patent, there is no guarantee the technology will reach a product. Sony has not confirmed that the feature will be part of the PlayStation 6, and companies routinely patent concepts that never leave the drawing board. The interest here is the signal: the fight against smurfing on PS6 could gain a behavior-based tool, not just player reports.
