At the Black Hat security conference, Roblox engineering manager Hao Zhang and principal privacy software engineer Yiwen Luo spoke about the company’s approach to operational privacy and data deletion.
One user request to delete data could trigger over 600 subtasks that need to be tackled by different teams and systems. According to Zhang, the entire system is complex and requires close collaboration between hundreds of systems; one of the biggest challenges was figuring out where exactly the data about the user is stored.
Luo added that per the privacy policy, Roblox collects and stores most information about the user for as long as the account is active on the platform.
The topics range from chat content, audio and video data, device information, and demography, to email and phone number, government ID and selfie for voice chat and other restricted content, payment information, and username, date of birth, and password. Roblox has experienced a 3.5X growth in year-over-year privacy-related user data requests.
The new federated management system aims to handle such requests in a more efficient system-wide manner across the company’s systems and data platforms, as well as the third-party ones storing user data.
Roblox is using artificial intelligence and other technologies to improve moderation, safety, and privacy on its platform. The company’s system, called Sentinel, is designed to detect harmful content and messages using machine learning algorithms.
Roblox also relies on a combination of human moderation and automated tools to review and filter game catalogs, chat content, and other materials. It implements preventive algorithms and age-estimation solutions as a part of its safety measures.
However, the growing use of tracking systems, tools, and the controversy around the age-verification laws in over half of the U.S. states have sparked debates regarding data privacy and potential risks to users’ safety and data privacy.
The expansion of Roblox’s operations has also led to increased scrutiny from regulators. After the games containing violent and extremist content were leaked, and the lawsuits regarding the company’s alleged role in facilitating predation and grooming were filed, Roblox’s moderation capabilities and safety tools have come under the magnifying glass.
The Roblox Sentinel documentation reveals that roughly 1,200 potential child-endangerment reports had been reviewed.
Still, there was no information about how many of those had been confirmed as actual cases.
While the new federated security system allows Roblox to have more visibility and control over where the data about its users is stored and how does the company handles data deletion requests, its transparency around the matter is limited by the amount of data the company stores about its users and the extent to which it monitors its platforms.
