imagine have game, need save data every user level, highscore, gold,... if saved of these locally (on user´s device) aren´t safe , modified user rooted device , bit of skill. (as discussed here ) so need put them on database on server - i´d connect webservice , json. but realized isn´t safer: if can apk, can decompile it, code used post highscore, , either edit post 1,234,567 (and compile again) or extract , post highscore. in case of highscore, it´s not big problem - this, it´s possible get/post that´s used in app. how can protect app/database against this? my ideas: encrypt post: can´t work, encryption happens on device encrypt post seed db: "hacker" can seed aswell, not safer generate key every connection: same first in 1 sentence: long "hacker" can mirror behaviour of app, there way of ensuring connection db opened app , not else? you need change approach this. if don't want user change data, don't put on device. se
