Your ISP and email
If you have signed up for internet service you have given away information to a business that now has also setup an email for you. Internet Service Providers (ISPs) give you an IP address that is unique to you. This address which is like a license plate on a car identifies you and under record retention policies are logged at your ISPs level. This means your internet service provider monitors where and when you surf the web.
Your email address including emails are backed up at the ISP level. Although you may delete personal or business emails, the ISP backs this information up for disaster recovery and planning on their end. If you use online email the same is true. Have you ever noticed the ads around the interface of your email match the contents of your email? In order to fund the 'free' email you use, the provider uses software to look through your email to find keywords and a custom ad is delivered to you.

Controls are in place with Facebook to limit the amount of information about you. Under the settlings in Facebook, you can control who sees your personal information, photos, posts and other information. You should always limit this information to friends and should further limit this information to friends who are not close to you. Placing personal information such as your address, employer and phone numbers (including your cellphone) can give malicious users access to information you don't normally give out. Limit this information that gives out demographic information about you.
Businesses on Social Sites are encouraged to give this information out but should limit phone numbers to business numbers only.
Photos can expose you and create a vulnerability that you are not aware of. Taking pictures of valuables and collectables can expose let someone know about these items. Pictures of your personal vehicle and license plates can let someone know information about how to find you.

Mobile Computing and Privacy
Have you ever thought that geo-location applications on your phone can give out information you don't want others to know?
Giving out your geo-location tells followers on Social Netwoks - 'I am here!'. This information could provide stalkers with where you, who you are with and what you are wearing! This is should be a grave concern for anyone. This information also tells the follower who is in your home and if it is vulnerable.
Using many of these mobile devices in coffee shops, schools or other hotspots also allows someone who is sniffing a network the ability to identify what the user is doing and where the user is surfing.
Consider disabling geo locating software and always use a VPN when connecting to a hotspot. Always make sure you know the network your attaching to. Malicious users can setup a virtual hotspot inside of a business such as a coffee shop and you can inadvertently connect to the 'hackers' network causing your data to pass through the malicious person's device.
