Confidence Values

Each time we face our fear, we gain strength, courage, and confidence

Smile Identity applies an ensemble of facial recognition algorithms designed to compare and predict potential matches of faces regardless of their expression, facial hair, and age.

Our service provides an estimate of the confidence level of the prediction in the form of a probability or Confidence Value.

Smile Identity has a confidence value between 0% and 100%, the higher the number, the more confident the system is about the match. The confidence score is an indication of the probability of us returning a false match/FAR (False Acceptance Rate). Smile Identity works with its partners to identity the specific use case and desired risk profile to set confidence score thresholds. The acceptance or rejection of a facial match is dependent on the score falling above or below the set threshold.

Machines and Humans, working together

As a guideline: Lower thresholds = More results; more suited for business non-critical use cases where there is lower risk or associated value Higher threshold = Fewer results; suitable for business-critical uses cases such as high value or sensitive transactions
