Our security measures are being improved continuously as technology develops.

We have no control over, and assume no responsibility for the content, privacy policies or practices of any third party sites, products or services.

9.3 Authentication and authorization of Authorized Users

The authentication of Authorized Users is completely managed by the hospital’s identity provider system, such as an Active Directory File Server (ADFS). This way, the hospital has complete control to determine password policies, which Authorized Users have access to StrokeViewer, enforcing multi-factor authentication, etc. Thus, when an Authorized User attempts to access StrokeViewer, this Authorized User is redirected to the hospital identity provider system. If the identity provider system used by the hospital does not support two-factor authentication, the hospital can use the StrokeViewer app to provide two-factor authentication.

Once authenticated, an Authorized User is authorized for:

  • 1 hour of web access to the product;
  • 336 hours (14 days) of mobile access to the product.

After expiring this period, the Authorized User is requested to authenticate themselves again. The extra security measures are also applied:

  • if the Authorized User account is suspended or revoked by the Customer’s identity provider their access to the product is automatically terminated not later than in 1 hour;
  • the mobile app requires Authorized User to provide an additional pin or biometrics for authentication;
  • web access is automatically locked after 20 minutes of inactivity to prevent unauthorized access to unattended sessions, to unlock it the Authorized User has to authenticate themselves again;
  • if Authorized User switched to another tab in the browser or to another window and does not return to the product’s web page for 10 minutes their web access is locked even if Authorized User keeps working with the other applications and/or browser tabs, to unlock it the Authorized User has to authenticate themselves again;
  • mobile access is automatically locked after 1 minute of inactivity to prevent unauthorized access to unattended sessions, to unlock it the Authorized User has to provide an additional pin or biometrics.

10. Personal Data breach and notification obligation

In the event of a Personal Data breach concerning the Services provided by Nicolab, Nicolab will promptly notify affected Authorized Users and, if applicable, relevant supervisory authorities, in the event of a Personal Data breach that poses a risk to the rights and freedoms of the affected Authorized Users. The notification will be made without undue delay after becoming aware of the breach, but within 72 hours at the latest. In the event of a Personal Data breach, Nicolab will take all reasonable measures to limit the consequences of the Personal Data breach and/or prevent a new one, against payment of the reasonable costs by you.
