protection

I'm working on a web service that would use an SMS gateway to receive instructions from customers. Since this would be a commercial product I would like to implement a safeguard to protect our system from SMS spoofs. I don't want people impersonating others by spoofing their number. I've noticed that Twitter allows people to tweet through text messages, how can they make sure that messages are actually genuine? Is this possible, and if so how do I accomplish this? Or should I ignore this and just deal with it through support should they get through. How do users spoof their numbers? Every

Closed. This question is off-topic . It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I've been looking for a simple key/license system for our users.

I know the basics of .htaccess, but freely admit to being a non-expert when it comes to mod_rewrite.

However, my rewrite rule does not seem to prevent access. .htaccess Options

I'd like to protect the worksheet to make it read-only (allowing sort, filter, pivot table usage). I know how to do this with the protect worksheet feature. But when the worksheet is protected, I can't use the Refresh button to refresh the data from the source and I want users to be able to do this. I

Please tell me how to protect our resource in a apk package. With a simple rename-extract process, any one can copy and thief application drawable resource like images or soundFX files. My question is, is there any way to protect drawable resource in a Android application? The drawable needs to be accessible to the operating system, so it has to be readable. If you really want to keep it secure, you could consider storing it encrypted as a raw asset, then load it, decrypt it into a ByteStream and pass it into the BitmapFactory. That, of course, has slight performance ramifications and will
