Fotoidentificação

Fotoidentificação is a method used to verify a person's identity through the use of a photograph. This process typically involves comparing a photograph of an individual presented on an official document, such as a driver's license or passport, with a live photograph of the person attempting to prove their identity. It is a widely adopted security measure in various contexts, including border control, access control to secure areas, and financial transactions.

The effectiveness of fotoidentificação relies on the quality of the photograph on the identification document and the ability to capture a clear, comparable live image. Factors such as lighting, camera resolution, and the presence of distinguishing facial features are crucial for a successful match. In some advanced systems, digital enhancements or facial recognition software may be employed to aid in the comparison process, looking for specific biometric markers.

While fotoidentificação is a common and generally reliable method, its accuracy can be affected by changes in a person's appearance over time, such as aging, weight fluctuations, or cosmetic alterations. Therefore, it is often used in conjunction with other forms of verification to ensure a robust identification process. The objective is to prevent impersonation and enhance security by confirming that the person presenting the identification is indeed the rightful holder.
