With the international push towards Electronic Health Records (EHRs) by the Health and Human Services (United States of America), National Health Service (United Kingdom), Health Canada (Canada) and more recently the Ministry of Health (New Zealand), this paper presents the consumers’ role with a focus on their perceptions on the security of EHRs.

In feature selection it is found that similar but different rankings for individual tone classification and solo passage instrument recognition are reported. Based on the feature selection results, excerpts from concerto and sonata files are processed, so as to detect and distinguish four ma jor instruments in solo passages: trumpet, flute, violin, and piano.

<p>We present an empirical study on classical music instrument classification. A methodology with feature extraction and evaluation is proposed and assessed with a number of experiments, whose final stage is to detect instruments in solo passages. In feature selection it is found that similar but different rankings for individual tone classification and solo passage instrument recognition are reported. Based on the feature selection results, excerpts from concerto and sonata files are processed, so as to detect and distinguish four ma jor instruments in solo passages: trumpet, flute, violin, and piano. Nineteen features selected from the Mel-frequency cepstral coefficients (MFCC) and the MPEG-7 audio descriptors achieve a recognition rate of around 94% by the best classifier assessed by cross validation.</p>
