Mechanisms are provided for detecting adversarial attacks on graph data structures. A first graph fingerprint engine generates, for a first graph data structure, a first fingerprint data structure-based on features extracted from the first graph data structure. A second graph data structure is received, and a second graph fingerprint engine generates a second graph fingerprint data structure based on features extracted from the second graph data structure. An adversarial attack detection engine compares the first fingerprint data structure to the second fingerprint data structure to determine whether the first fingerprint data structure matches the second fingerprint data structure. In response to the first fingerprint data structure not matching the second fingerprint data structure, the adversarial attack detection engine outputs an output indicating that the second data structure corresponds to an adversarial attack.
