Title: Graphical Authentication
Post by: jhardis on March 06, 2010, 03:26:16 PM
Using graphical authentication, I have a great deal of trouble distinguishing "0" and "O", "5" and "S", and "8" and "B".  Is there a rule of thumb to tell them apart -- like some characters not being used at all?

Thanks!

Recently, DLink have updated the newer firmwares with this graphic authentication turned off.

I know, but this isn't an answer to the question.

I actually prefer to leave graphical authentication on, but would like to reduce the number of errors due to ambiguous characters.

Unfortunately, there is no way to improve or limit the characters used.  They're supposed to be randomly generated.  Perhaps D-Link could leave out the questionable similarily looking characters in future updates.

The graphical authentication is using an older style than the current one.  I have seen the newer "better" implementation on several web site

   I have observed that D-Link uses the hexadecimal numbering system for the graphical authentication process, that is 0-9, and A-F. While this greatly reduces the number of erroneous combinations, it is still sometimes difficult to distinguish a "0" from a "D" and an "8" from a "B" and a "2" from a "3" when the numbers are "scrunched up" from the bottom.
