Information Handling by Some Health Apps Not as Secure as It Should Be
Some health apps that have been clinically-accredited may not have been complying with principles of data protection, according to research published in September 2015 inthe open access journal BMC Medicine. In some instances health apps were found to be sending unencrypted personal and health information, which means users of these apps may have had their privacy put at risk.
A release from the publisher notes that use of smartphone health apps is now at an all-time high. It is currently estimated that one and a half billion smartphone users have a health app installed and this number is set to treble in the next three years. One quarter of US adults have reported using one or more health apps and a third of physicians have recommended an app to a patient.
As a way of reassuring users about the quality and safety of health apps, several app accreditation programs have been launched. One such program is the UK’s NHS Health Apps Library, which is a curated list of apps for patient and public use. Registered apps undergo an appraisal process that examines clinical safety and compliance with data protection law. To be listed in the Health Apps Library, developers are required to declare any data transmissions and register with the UK’s Information Commissioner’s Office – the body that enforces the Data Protection Act.
The release quotes lead researcher, Kit Huckvale, Imperial College London, UK, as saying, “Our study suggests that the privacy of users of accredited apps may have been unnecessarily put at risk, and challenges claims of trustworthiness offered by the current national accreditation scheme being run through the NHS. The results of the study provide an opportunity for action to address these concerns, and minimize the risk of a future privacy breach. To help with this, we have already supplied our findings and data to the NHS Health Apps Library.”
The researchers from Imperial College London, UK, and Ecole Polytechnique CNRS, France, reviewed 79 apps that were listed on the UK NHS Health Apps Library in July 2013 and are available on Android and iOS platforms. The apps covered health areas such as weight loss, alcohol harm reduction, smoking cessation and long-term condition self-care.
