The Quantified Self website provides a current list of many of the self-tracking tools out there.

From the HealthIT.Gov website: "Blue Button" is a way for you to get easy, secure online access to your health information. To "Blue Button" means you can "download your health data" so you can use it to improve your health and be more engaged in your healthcare. As Americans, we each have the legal right to access our own health information held by doctors, hospitals and others that provide health care services for us. But many of us don't, either because we don't know we can, or because we're not sure what to do with our health information once we have it. Until recently, most medical information was stored in paper files, so it wasn't very easy to access or use anyhow. But all that is changing as more health care providers (doctors and hospitals) adopt electronic health record systems and other health information technology (health IT). Patients will have more opportunities to get access to their health records electronically and to engage with their clinical teams about their medical records.

From the Federal Trade Commission website: A thief may use your name or health insurance numbers to see a doctor, get prescription drugs, file claims with your insurance provider, or get other care. If the thief’s health information is mixed with yours, your treatment, insurance and payment records, and credit report may be affected.

If you see signs of medical identity theft, order copies of your records and check for mistakes. You have the right to see your records and have mistakes corrected.
