Datafly algorithm
WebJul 26, 2024 · Datafly algorithm is an algorithm for providing anonymity in medical data. The algorithm was developed by Latanya Arvette Sweeney in 199798. Anonymization is achieved by automatically generalizing, substituting, inserting, and removing information as appropriate without losing many of the details f WebEach algorithm's performance speed was also evaluated. Results: The Datafly and Samarati algorithms had higher information loss than OLA and Incognito; OLA was consistently faster than Incognito in finding the globally optimal de-identification solution.
