The purpose of a captcha (as flawed as the concept may be) is to filter out spam (comments etc.)
The idea behind a traditional captcha is to present a task that is easy for a human to solve (ha-ha) but hard for a computer.
As far as I can tell, your method does not rely on this principle. Which means that you use some machine-readable scheme that relies on obfuscation to provide this function.
While that method may work individually, it does stop working as soon as your method gains any kind of traction, because then spammer will target exactly your scheme and any advantage is null, void and gone.
- Jhsto 14y agoI'm aware of this, but in my distinct opinion it is at least worth of trying. Spammers make money out of posting links all over the web and crackers make it by selling compromised accounts or the personal information attached to them. Even if it would work only for a brief time it surely would make their job harder and the overall process much more slower. But then again, this is just my opinion and I've convinced myself it to work - for that brief time only if nothing else.
