In an approach to establishing personal identity using multiple sub-optimal images, a method includes receiving a set of sub-optimal input images, identifying a first and a second user feature in the set of sub-optimal input images, and determining a confidence score of the user features by comparison to user profile images. The method additionally includes determining a combined confidence score of the first user feature and the second user feature and determining whether features match a user by: (i) determining whether the combined confidence score is higher than a pre-determined threshold for the combined confidence score, (ii) determining whether the confidence score of the first user feature is higher than a pre-determined threshold for the user features, and (iii) determining whether the confidence score of the second user feature is higher than the pre-determined threshold for the user features.
