If that is the case I'd suggest using a hash to encode your username
with a "salt" that you only know, for example:
import hashlib
salt = "my secret passphrase"
hash_info = hashlib.sha256('%s%s' % (username, salt)).hexdigest()
Under this scenario, assuming that usernames are unique, for user
"john" the hashed URL "part" would be:
print hash_info
'4c481672be4c3c245ad47ebcdf8cb48330fd18b70117a5353db8fe0841ab8dee'
So you can now compare the hashed entry to the user and see if it a
valid one. There are many ways to go about doing this, this is just an
example, of course,
Cheers
