In today's world, healthcare is the most important factor affecting human life. Due to heavy work load it is not possible for personal healthcare. The proposed system acts as a preventive measure for determining whether a person is fit or unfit based on person's historical and real time data by applying clustering algorithms like K-means and D-stream. The Density-based clustering algorithm i.e. the D-stream algorithm overcomes drawbacks of K-Means algorithm. By calculating their performance measures we finally find out effectiveness and efficiency of both the algorithms. Both clustering algorithms are applied on patient's bio-medical historical database. To check the correctness of both the algorithms, we apply them on patient's current bio-medical data.
