Abstract:In the process of DNA motif finding in data sharing platform, preventing individual information leakage become a research focuses in this field. Aim at this problem, this paper designs and implements a differential privacy-based DNA motif finding security sharing platform, adopts sever DNA motif finding algorithms that satisfy the differential privacy protection model, and realizes data source selection, algorithm selection, privacy budget setting, result evaluation, graphical result display and etc. Moreover, in addition to finding motifs of the built-in DNA datasets, the platform also allows researchers to upload and share DNA datasets and find motifs of the sharing DNA datasets, providing a safe and reliable genetic sequence analysis research and data sharing platform for researchers. The tests prove that the secure sharing platform can effectively find motifs and safely share DNA data, and the design is feasible.
