A Way to save Vars

[projectigi]

Hi,

so i had the idea of doing untouchable vars

double saved(in 2 subvars)
in a format like
this.34klj66$&!$j5lkj325j^!"5623#152#5jlkjkrqewklj rw.varname
and second
this.fjklsdfjlk24jkl152lk4j6jl1tö3jlk1l34jk16jkl4 35lkj324jlk152.varname
so noone can access it easily, since they wont be able to find out the varname with the getdynamicvarnames and getvarnames functions disabled

now, my problem is, i wanna keep these vars after logout of the player, but i dont wanna save em to a file, npc or client./clientr. strings because then they get easily modified :/

any idea how i could save em?
