Estudo de estratégias de detecção de trapaças em jogos online

Abstract

As in software in general, security is also relevant to online games quality. One of the faced problems is the use of cheats, which can cause economic loss for companies, as well discourage online product consumers. One of these cheats consists on modifying the game client source code and/or running a third party application over the game that allows the user to change client information, or even adulterations to access sensitive game states that usually are not available to the player. These problems can be corrected with the use of different strategies and tools, which can be optimized to specific scenarios or become unworkable due to over-processing. This work presents a study of different methods of validating existing messages, running some of the methods on a game prototype and analyzing their characteristics. The results of using SSIP proved to be efficient at run time, while the verifier with symbolic execution was considered inefficient, in addition to showing difficulties to verify massive messages.
