Accuracy

Department of Defense parlance for the notion that information has been maintained and transferred in such a way as to be inviolate (the information has been protected from being modified or otherwise corrupted either maliciously or accidentally). Accuracy protects against forgery or tampering.

the degree of conformity of a measured quantity to its actual (true) value.

How closely an instrument measures the true or actual value of the process variable being measured or sensed.

Degree of conformity of a measure to a standard or true value; in other words, how close a predicted or measured value is to the true value.

Accuracy The extent to which the results of readings of an instrument approach the true value of the calculated or measured quantities, supposing that all possible corrections are applied.

A catch-all phrase for describing how well a biometric system performs. The actual statistic for performance will vary by task (verification, open-set identification (watchlist), and closed-set identification). See www.biometricscatalog.org/biometrics/biometrics_101.pdf for further explanation. See also d prime, detection error trade-off (DET), detect and identification rate, equal error rate, false acceptance rate (FAR), false alarm rate (FAR), false match rate, false non-match rate, false reject rate, identification rate, performance, verification rate.

The degree of conformity of a measured or calculated value to its actual or specified value.
