Clarius Ultrasound Scanner - HD3 Scanners Security
revision 1 20
• Wi-Fi network where only trusted parties are permitted. The Wi-Fi network
encrypts all image data sent from other Wi-Fi networks.
• Wi-Fi Direct network. The Wi-Fi Direct network encrypts all image data, and
because no other users are on the Wi-Fi Direct network, the image data is
confidential.
• If no images are exported to Clarius Cloud or DICOM, the Clarius App stores them
indefinitely. If images are exported, these images will be deleted from the device 10 days
after export by default. You can change this default in the Clarius App’s Settings page.
Integrity
Integrity of the data transmitted between the Clarius Scanner HD3 and the Clarius App is
assured as follows:
• Authenticated encryption prevents malicious users from intercepting and modifying data.
• Integrity checks ensure completion and validity of data received. If any data is incomplete
or invalid, it is discarded.
• TCP channels used over Wi-Fi ensures that data is delivered correctly. For transmitting
image data, a UDP channel is used.
Availability
If Wi-Fi connection is unattainable (e.g., Wi-Fi access points are unavailable, or the network is
down), use Wi-Fi Direct network, which is managed by the smart device. Because Wi-Fi Direct
network is a peer-to-peer connection using the Wi-Fi protocol, it disallows other users from
connecting, thereby reducing DDOS (Distributed Denial of Service) attacks.
If the Wi-Fi Direct network is disrupted, the Clarius Scanner HD3 continues to monitor itself,
and shuts down after a period of inactivity. This reduces acoustic energy transmission and
battery usage.
Accountability
The concept of accountability does not apply to the Clarius Ultrasound Scanner. However,
ownership (i.e., the active user) of a smart device is assigned to one user at a time. Once you
begin using the smart device, no other user can connect to the same smart device. All data
transmitted between the smart device and the Clarius App is owned by the active user.
