Question

How to prevent memory hacking in game's score?

Hi,

I'm building a java mobile game and i need to prevent people from hacking the score via the memory. I thought of maybe like this,

-Instead of using numbers in the score's main variable, we use Alphabets like 1=AG, 2=RE
-So the canvas or display just reads the score's alphabets and translate it to a number.

Will this work? If no, do you any better idea?

Hi Melwong,

I believe your solution will work, and I'm not a java expert to propose a better sollution (may be, something with a fancy asymmetric key encryption, or something which stores the score on the servers of mobile operator or the game author?) just have a question: why?

As I understand the situation, people download games to their mobile phones and don't use to borrow the phones to somebody [...evil, who'll intimidate the phone owner by impressively hacked score...] for playing games... They don't get any "free minutes" bonus for playing this games also.

So, if they feel happy to hack into the memory of the mobile and change the score, why they shouldn't?

BR,
