Please add systemInfo integrity checks to improve Bedrock safety

I would like to request the addition of integrity checks for systemInfo in Minecraft: Bedrock Edition.

Currently, the client‑provided systemInfo is not verified for authenticity. Because of this, modified or spoofed device information can bypass server‑side checks, which reduces the safety of Realms and general multiplayer environments.

Why this is a problem • systemInfo can be easily spoofed on unsupported or modified devices • Servers cannot reliably identify the client’s real environment • Safety features that rely on systemInfo become ineffective

Why legitimate players would not be negatively affected • Older devices such as Android 8 or iPhone 8 are already below minimum requirements or non‑recommended • Rooted devices and custom ROMs are not officially supported • MDM‑managed devices are not intended for gaming use → Therefore, the number of legitimate players impacted by integrity checks would be extremely small

What I am requesting • Add basic integrity verification for systemInfo • Validate consistency between device model, OS version, and hardware capabilities • Detect and flag clearly impossible or modified combinations

Expected benefits • Stronger protection for Realms and multiplayer • Reduced spoofing and impersonation • Better safety for children and general players

This is not a bug report but a feature request focused on improving player safety. Thank you for considering this.

  Additional note: This suggestion focuses on improving safety for Realms and general multiplayer. It does not negatively affect legitimate players because unsupported or modified devices are already outside official requirements.

  Additional explanation:
  The current Bedrock system works like a country where the “passport” (systemInfo, permitted, etc.) can be easily forged. Even if the information is fake, servers often accept it without verification, which allows unauthorized players to join servers very easily.
  In contrast, Java Edition works more like a country with strict identity verification. Before accepting a player, the server can verify:
  “Are you really this player?” (via signed data and public key verification)
  “Is the UUID valid?”
  “Is the client information legitimate?”
  Only when all checks pass does the server allow the player to join.
  This is why adding systemInfo integrity checks to Bedrock Edition is important. It would give servers a reliable way to confirm whether the client information is genuine, improving safety without affecting legitimate players.
