How should you verify that two photos show the same person?

Verifying that two photos show the same person is most effectively accomplished by comparing facial IDs derived from both images. This method leverages facial recognition technology that analyzes key features and attributes of a person's face, converting them into a unique identifier, or facial ID. By comparing these IDs, it provides a quantifiable measure of similarity between the two photos. If the facial IDs are sufficiently close, it indicates that the same person is depicted in both images.

Comparing facial IDs is a highly accurate and efficient approach, especially when dealing with varying angles, lighting conditions, and facial expressions that can affect visual inspection. This technology is widely used in applications such as security, social media tagging, and identification systems due to its reliability and speed.

In contrast, creating a People Group for every hospital visitor involves organizing images into groups, which does not directly address the verification task. While it may be useful for managing multiple identities, it doesn't specifically aid in confirming if two particular photos show the same person.

Examining physical characteristics, such as height, build, or attire, introduces a subjective element and can lead to inaccuracies due to variations in presentation or perception between different observers. Moreover, such characteristics may change over time or may not be visible in both images.
