Valuable functionality can cause a privacy breach

Last Friday it was revealed that reporters from Bloomberg News could retrieve information from the profiles of subscribers to Bloomberg’s data terminals as well as the subscribers’ system usage (NYT article here). While I agree with the characterization of this incident as a “mistake”, wasn’t this really a violation of basic privacy principles?

The ability to see user profiles and their system usage is a valuable feature that can be used by administrators or help desk staff. However, this is the type of functionality that should be restricted to those who have a need to know.

No matter which data privacy framework you prefer, there is a tenet that states that personal information should be used for the purpose specified at the time of collection (or in the privacy notice). A corollary to this would be that any additional use would require an additional disclosure to the data subject. In the Bloomberg case these maxims were just not followed. Implementing a role-based authorization scheme would have allowed the retention of the functionality while protecting subscriber privacy.

One needs to ask if, at the time of development, privacy requirements were included in the specifications for the application. If not, it was clearly a mistake. Alternatively, it would not be unusual for the capabilities of the application to grow over time resulting in the potential for undisclosed access. If so, one needs to ask if privacy requirements were considered as new functionality was developed. In either situation the principles of Privacy by Design could have been leveraged to avoid the privacy breach.

It is a fair assumption that the functionality was not a secret within the Bloomberg News organization. An additional concern then is that either no one thought enough of the potential privacy implications to report the privacy risk or no one recognized that a privacy risk existed. This underscores the need for a clear internal privacy policy with supporting training and awareness programs.

By considering privacy requirements up front and establishing an effective privacy training and awareness program, the brand damage, public relations, and relate operational costs of addressing situations such as this can be avoided.

Don’t Forget Basic Communication
Most of us have been wrapped up in GDPR preparations for several months. While there are many organizations "not quite there yet", many others have made great strides towards compliance. As we continue to do assessments for clients, both GDPR and General Privacy,  I have been surprised at the frequency of the gap between a privacy official describing their organization's data subjects, information collected, and business processes  with the reality of what is happening.

California – The Next GDPR?
Starting January 1, 2020, if you are a for-profit company doing business in California, you may have new data privacy compliance obligations. Specifically, California just enacted the California Consumer Privacy Act of 2018 (the country’s strictest data privacy law to date), placing new privacy mandates on certain businesses with respect to the personal information of consumers (defined as natural persons who are California residents). Many aspects of the new law smack of EU-GDPR influences, such as a new and improved (in other words, broader) definition of personal information and the inclusion of guaranteed consumer rights with respect to such personal information. If your business is already in compliance with the EU’s GDPR, the California law will be nothing new to you. For other businesses, however, you have 18 months to get with the program.
