Many websites require users to confirm 'I'm not a robot.' Which data-related issue is this an example of?

Asking a visitor to confirm they are not a robot is a data security measure that blocks automated abuse.

Accuracy concerns whether stored data is correct, which this check does not address.

Matching concerns linking records that refer to the same entity, unrelated to this test.

Quality is the broader fitness of data for use, not this specific access safeguard.

Such CAPTCHA tests separate genuine humans from bots and scripts.

They protect forms and logins from spam, brute-force and scraping attacks.
