Computer based implants

The idea

Computer-based implants are digital devices placed inside the body, such as a cochlear implant, a pacemaker with digital control or an identity chip. They sense or act on the body and may communicate wirelessly with external equipment. Within 3.8, the key issues are ethical, legal and environmental, including privacy. Implants can hold or transmit sensitive health or identity data, so consent, security and who may access the data matter. Legal questions include data protection and medical regulation; ethical questions include autonomy and the risk of hacking; environmental questions include safe disposal of implanted electronics and batteries. A strong answer names the implant, the data or function involved, and a specific impact.

What earns the marks

• Identifies a computer-based implant as a digital device placed inside the body, e.g. a pacemaker or cochlear implant.
• Explains the function or data involved, such as monitoring health or transmitting identity information.
• Links the implant to a privacy concern, e.g. sensitive health data, security of wireless transmission or consent.
• Recognises an ethical, legal or environmental impact, e.g. risk of hacking, data protection law or safe disposal of the device.

Common mistakes and how to put them right

• Confusing an implant with a wearable.

  Put it right: An implant is placed inside the body, whereas a wearable is worn externally.

• Assuming implanted data is automatically secure.

  Put it right: Wireless transmission can be intercepted, so security and privacy must be considered.

• Overlooking disposal; correction: implanted electronics and batteries must be removed and disposed of safely, which is an environmental issue.

Exam tips

• State clearly that the device is inside the body to distinguish it from a wearable.
• Tie your point to one of the four focuses: privacy, ethics, law or environment.
• Give a specific example, such as a pacemaker sending health data, to make the impact concrete.
