1. Team #4 Project Health Monitor To create a device that measures and logs weight and blood pressure with the data accessible from the internet Team #4 Dan Chapman Mike Goodwin Joe Isca Brent Rager

2. Health Monitor – Ethics  Confidential Health Information  Issue Weight and blood pressure information stored in non- volatile memory Information could be stolen by knowledgeable attacker  Solution Encrypt information using simple encryption algorithm (RC4) Each user’s individual information will be encrypted using his/her pin as the key

3. Health Monitor – Ethics  Confidential Health Information (Continued)  Issue Weight and blood pressure information transferred over TCP/IP Information could be stolen by knowledgeable attacker  Solution Send encrypted information to client application with knowledge of the encryption key Will be difficult to achieve security when serving data directly from the device Use JavaScript to decrypt the information on the client side (using user’s pin as key)

4. Health Monitor – Ethics  Safety  Avoid sharp corners in package design  Warning label for tipping hazard  Publish safety information from external devices (scale and blood pressure monitor) in user manual

5. Health Monitor – Environment  Manufacture Phase  Lead in parts Use RoHS compliant version or alternative part  Normal Use Phase  Low power consumption (infrequent use)  No batteries  Disposal Phase  Metal packaging should be recyclable  PCB and LCD disposed of (landfill)  Disposal process for external devices (scale and blood pressure monitor) will be published in user manual
