What are the security implications of doing this? I have a form on my localhost machine which I fill in and then this data gets submitted via POST to the live server, where it is run as a mysql query to update the live database. This is currently the easiest way for me to keep both local and live databases in sync. Should I look to md5 the data or anything like that, or is it OK the way it is currently?
why not adding a password and compare that with one on the server, notice that you should encrypt it with something like time, or another variable before sending it over to the other server
