Ask Slashdot: Copy Protection Advice For ~$10k Software?

KronicD Re:dongle (635 comments)

This isn't true in most cases, the algorithim is known as it is present in the memory of the cracker's computer. A debugger (typically OllyDbg or Immunity Debugger) will be used and the algorithim identified and replicated in the form of a keygen.

The dongle method moves that algorithim to an external component, if that component is simply returning a serial or some such it is easy enough to patch. However if critical functionality exists on the dongle, then the cracker would have to emulate this or otherwise fill in the missing functionality in the compiled binary. This is no small task (but has been done before).

So a dongle that contains core functionality and only accepts signed code and has an encrypted update mechanism will be quite robust in terms of protection offered. However when you have a 10k price on your product, it opens the door for commercial piracy ventures to move in, these guys have no problem cloning hardware and will be selling your software for 5k a peice instead of 10.

So yeah, dongles can work well at stopping non-commercial piracy.

Microsoft Puts the Kibosh On Kinect Sex Game Plans

KronicD Re:Obligatory (419 comments)

The Xbox won't run unsigned code, Microsoft have to sign the executable with their private key.

So if MS don't give it the go ahead, it wont run.

So you can develop and distribute it all you want, but without MS love it wont actually be usable on the Xbox platform.

Plagiarism Inc.

KronicD Re:yea, this is clear, but what about.... (236 comments)

As a researcher at a university I can safely say that 1 through 3 don't happen anymore. As for 4 & 5, managing those students is harder than doing the work yourself. We have to give those students the opportunity however (even though we almost always end up re-doing the work ourselves).

Nintendo Wins Lawsuit Over R4 Mod Chip Piracy

KronicD Re:Games from different regions? (146 comments)

Yeah, thats the legal protection most mod chip providers use in Australia. I got myself through uni by modding consoles and working helpdesk. I never touched a region free console like the DS or PSP, for this exact reason.

Does a Lame E-Mail Address Really Matter?

KronicD Re:Actually yes -- in some cases (1049 comments)

Because it allows you to change ISP without issue. I've had my email addresses professional & personal for over a decade. I would hate to have to have to ask everyone to update their contacts whenever I swaped ISPs.

You can do this for less than the $40, I get mine from http://rofltron.com/ and host the email with google apps, but they include free email forwarding if you'd rather just keep receiving mail at your ISP address.

The advantage is portability. I know people who are still paying ~$10 a month to some ISP to keep forwarding their email. You don't want to be in that situation.

Wii Hacked for Better Homebrew Games

KronicD Re:Smart Thinking (196 comments)

For 1.6 xboxes I'd suggest installing a physical chip, but I've never been a fan of softmods.

As for your link, that refers only to linux support, other homebrew applications (those made with the xdk) run fine on 1.6 machines.
