【安全加密】设备指纹：多开检测的关联识别

---设备指纹的组合采集
function DeviceFingerprint.collect()
    local fp = {
        cpu = sysinfo.cpuModel,
        gpu = sysinfo.gpuModel,
        mem = sysinfo.totalMemory,
        disk = sysinfo.diskSerial,
        mac = sysinfo.macAddress,
    }
    local fpHash = md5str(table.concat({ fp.cpu, fp.gpu, fp.mem, fp.disk, fp.mac }, "|"))
    return fpHash
end

---同设备多账号的检测
function DeviceFp.multiOpen(deviceFp)
    local accounts = deviceAccounts[deviceFp] or {}
    if #accounts >= 5 then
        local allSameGuild = checkSameGuild(accounts)
        if not allSameGuild then
            QF_RiskAlarm("设备多开", deviceFp, #accounts)
        end
    end
end
