Devices are pre-deployed with an app security mechanism to ensure that apps that are downloaded onto the device do not cause data loss, data leakage, or other harm to the device. A user can start using the device and downloading apps in a conventional or typical manner and be assured that security measures are being taken to minimize potential harm for unsecured and secured apps. An app security enforcement layer or engine operates with, for example, a Type 2 hypervisor on the device, and ensures that any calls by the apps to the operating system of the device are generally safe. Measures such as enhancing or modifying the call, obfuscating the call, or terminating the app may be taken to protect the operating system. These actions are taken based on a policy that may be either interpreted or compiled by the enforcement engine with respect to app execution. The security measures are generally transparent to the user of the device.

The invention relates to a garbage burning fly ash sintering harm-eliminating resource-utilization treatment technology. According to the invention, garbage burning fly ash is mixed with premixed coal and auxiliary materials; the mixture is granulated and shaped; and the material is dried and is sintered in a rotary kiln. During the sintering process, when the temperature is increased and a coal ignition point is reached, the premixed coal is spontaneously combusted. Therefore, external coal dose can be reduced. Initial combustion of the premixed coal can provide a reductive atmosphere, such that dechlorination and detoxification of dioxin in fly ash can be benefited. Large amount of gas is produced by subsequent combustion, such that dust pores and holes are produced on inner and outer parts of the sintered body, and heavy metal volatilization can be promoted, and fly ash sintered body with low heavy metal content and leaching amount can be obtained. The sintered body has no potential harm to the environment, such that fly ash harm-eliminating and resource-utilization are sufficiently realized. During the processing process, smoke and secondary fly ash production amounts are low, and heavy metal and acidic component contents are high. In deacidification and heavy metal stabilization processes, agent utilization rate is improved. Compared with a traditional original fly ash curing/stabilizing process, a landfill amount can be reduced by 80-90%, such that pressure caused by serious landfill space shortage can be effectively relieved.
