An approach is provided for spatial-temporal authentication. The approach involves, for example, receiving first image data captured by a first camera device and depicting an object positioned at a location, and second image data captured by a second camera device depicting the object and captured within a time threshold of the first image data. The approach also involves processing the first image data to extract one or more first object features and the second image data to extract one or more second object features. The approach further involves determining a match between the one or more first object features and the one or more second object features. The approach further involves providing an authentication output indicating that the first camera device and the second camera device are or were at the location of the object within the time threshold.
