Encryption / Protection in SPSS v17

[Brad Kirby]

Hi,

Is it possible to encrypt a specific variable only in an SPSS data file in v17?

Is it possible to encrypt an SPSS data file in v17?

Something similar to this

Although this is for v16 and im not even sure if it was officially released
globally?

Thanks
Brad

since the 1970s I have "encrypted" (hidden) string variables e.g.,
social security numbers by something like this untested syntax. (the
file specs and the random number functions have changed but that should
make little difference in this application.)
get file...
compute rannum = uniform(2e31).
sort cases by rannum.
compute ranid=$casenum.
xsave outfile = 'd:\project\job123 key.sav'/keep= ranid, ssn.
save outfile = 'd:\project\job123 clean.sav'/drop=ssn.

I have been using version 16 for a while and just started with 17.
I have a curious error .

I often use the menus to build my syntax.
Recently I have found that  when  I use the FILE    -> OPEN  ->DATA menu and
specify  a .SAV file and then attempt to paste this command into my syntax, the system opens up  the file
import wizard and "thinks" that I am trying to import a text file.

Although this has happened several times it does not always happen so it is difficult to document the chian of events
 but once this happens I cannot open any spss save files other than through syntax.


Has anyone else run into this?

thanks
