    While encryption might be a solution, my idea is that you should thry to read/understand a bit about access by user/group/world to files.
    You most probably have created both users in the same group (default is users) and also by default when a user creates a file, it is made readable by the group and even by the world. It is the responsability of each user to protect his/her files. Thus either a user could change his/her umask in e.g. .profile such that all he/she creates is not made accessible by any others, or he/she should change the access to those individual files that must be kept secret (using chmod or his/her favorite file manager).

    When you, as system manager, create new users, you should also allways have a policy if that new users should go in a different or the same group as other users you have allready. Classical example is of course that users of the finance department are in the same group and those in the manufacture department go into another. This seems to be a bit overdone in a home system, but this is how Unix/Linux works.

    Encryption is not a solution for this problem, because when one user is
    logged in, the other one can read those files. The permissions have to be
    changed, as you say.
