[RESOLVED] How to secure local database? Encrypt/Obscurication/Compile?

[experience]

I've attached data files from 2 of my competitors - data.tqs & data.dat

Please try and read the data - You cant!

I'm not going to spend hours decompiling their source code, they've done enough to secure it from prying eyes

I know someone somewhere could decompile it but it wouldnt be worth the hassle for the data it contains

My competitor doesnt need to even look into my sourcecode to get into my database -encrypting my connection strings is pointless!
A quick google and they can reveal the access database password in minutes http://tinyurl.com/brxmrbc

What i want is to obscurificate the data in my access database so should it be viewed will not mean anything to anyone but a good cracker!
