Passcode lock question

[Slicktype]

I have been using passcode lock on my 4s for a couple months thinking that there was no one that could possibly know my password.
Recently I started noticing texts that I had not read and started thinking maybe someone in my house is going through my phone.
Is there any way of knowing at what times the phone was unlocked, if there were any wrong attempts trying to enter the passcode and what not ?
I'm just trying to learn everything I can a mbiut passcode lock for future referece.
Thankss
Jo

If you download the iPhone Configuration Utility you can force a password unlock, which is a lot better than a 4-digit code that is usually someone's birthday or "1234."

Change your password, someone in your house guessed it or watched you typing it in.

I have searched but I can't find an answer. Is there a way to track how many times your phone has been unlocked throughout the day? Using passcode.
Also if there has been any incorrect pass code entrance

No, not unless you jailbreak it.

Change your pass code now.

If your jailbroken you can use a tweak to also lock out apps and settings in your phone with an alternative pass code. Acts as a second defence.
