S. Suganthi, T. Sree Kala · 2023
With the advanced improvement in E-government information sharing mechanism, the secure information sharing is beneficial and challenging. The consortium blockchain offers a new idea and ways to share the government information in secure and effective manner. Hence, this research study utilized various techniques corresponding to privacy preserved data sharing based on execution time, transactions per second, validation time, data loss, computational overhead, computational cost and so on. This survey utilized 25 research papers focussed on various techniques for privacy preserved data sharing techniques, and the review of researches technique-wise are provided. Finally, the analysis is promoted in the survey based on the research technique, year of publication, performance measures and achievement of the research methodologies towards privacy preserved data sharing techniques. Moreover, the research gaps and issues of the utilized techniques are explained, such that the motivation for developing an effective method for privacy preserved data sharing technique based on evaluation metrics is revealed.
