Differential privacy statement from Apple

This is an interesting statement and Apple, I think, needs to be commended for raising the bar on issues of addressing privacy concerns as it has so much access to data.

    You know how Zukerberg had to testify before Congress related to Facebook privacy, I wonder what Congress would think if Apple had to share this formula with them.....

    The noise injection step works as follows: After encoding the input as a vector using a
    hash function, each coordinate of the vector is then flipped (written as an incorrect
    value) with a probability of 1/(1 + �
    �/2), where � is the privacy parameter. This assures
    that analysis of the collected data cannot distinguish actual values from flipped values,
    helping to assure the privacy of the shared information.

    This is a cool article on the depths taken to secure info and insure it truly is de-identified.

IHI or the Institute for Health Care Improvement, the brain child of Don Berwick (remember the triple aim from Brian's class!) has partnered with edx.org to offer free online courses you can audit or even get a certificate for a modest price on some of the topics that can complement our MHI/MHA experience. There are also courses in different languages and different disciplines, not just medicine and health care.
