Cite two examples of physical changes that might keep biometric identification from working properly.

Immutable and device independent

Explanation:

Fingerprints: Fingerprint scanners have become ubiquitous in recent years due to their widespread deployment on smartphones. Any device that can be touched, such as a phone screen, computer mouse or touchpad, or a door panel, has the potential to become an easy and convenient fingerprint scanner. According to Spiceworks, fingerprint scanning is the most common type of biometric authentication in the enterprise, used by 57 percent of companies.

Photo and video: If a device is equipped with a camera, it can easily be used for authentication. Facial recognition and retinal scans are two common approaches.

Physiological recognition: Facial recognition is the second most common type of authentication, according to Spiceworks, in place at 14 percent of companies. Other image-based authentication methods include hand geometry recognition, used by 5 percent of companies, iris or retinal scanning, palm vein recognition, and ear recognition.

Voice: Voice-based digital assistants and telephone-based service portals are already using voice recognition to identify users and authenticate customers. According to Spiceworks, 2 percent of companies use voice recognition for authentication within the enterprise.

Signature: Digital signature scanners are already in widespread use at retail checkouts and in banks and are a good choice for situations where users and customers are already expecting to have to sign their names.

DNA: Today, DNA scans are used primarily in law enforcement to identify suspects -- and in the movies. In practice, DNA sequencing has been too slow for widespread use. This is starting to change. Last year, a $1,000 scanner hit the market that can do a DNA match in minutes -- and prices are likely to keep dropping.

I hope this helps you in any shape or form.

how much wood did the woodchuck chuck since a wood chuck can chuck wood.

xd

btw woodchucks cant chuck wood.
