How to create a table with hidden/profiled columns

I want to create a table, some of the columns shouldn't be included in a SELECT * statement. Follows an example:

SQL> create table temp

2 (

3 c1 number,

4 c2 number,

5 c3 number

6 );

Table created.

SQL> insert into temp values (1,2,3);

1 row created.

SQL> select * from temp;

C1 C2 C3

---------- ---------- ----------

1 2 

I want C3 to be a "hidden" column and while selecting like 

select * from temp;

expected output is...

C1 C2

---------- ----------

1 2 

My main target is, C3 column should not display in SELECT * statement, but column with data should be there in table. The best would be profiling the inclusion of C3 in the SELECT * stm depending on grants owned by the user.
