Improved l-Diversity: Scalable Anonymization Approach for Privacy Preserving Big Data Publishing
Scalable l-Diversity (SLD) is improvised in terms of data utility as Improved Scalable l-Diversity (ImSLD) for Privacy Preserving Big Data Publishing (PPBDP). The proposed algorithm is implemented using Apache Pig and Python over Apache Hadoop cluster.
Towards privacy preserving unstructured big data publishing
Scalable k-Anonymization (SKA) is improvised in terms of data utility as Improved Scalable k-Anonymization (ImSKA) for Privacy Preserving Big Data Publishing (PPBDP). Conditional Random Fields (CRF) based Named Entity Recognition (NER) is used to convert unstructured data to structured data. The proposed algorithm is implemented using Apache Pig and Python over Apache Hadoop cluster.
Scalable l-Diversity: An Extension to Scalable k-Anonymity for Privacy Preserving Big DataPublishing
Scalable k-Anonymization (SKA) approach is extended for l-diversity as Scalable l-Diversity (SLD) for Privacy Preserving Big Data Publishing (PPBDP). The proposed algorithm is implemented using Apache Pig and Python over Apache Hadoop cluster.
Toward Scalable Anonymization for Privacy-Preserving Big Data Publishing
Scalable k-Anonymization (SKA) approach is proposed over Hadoop cluster for Privacy Preserving Big Data Publishing (PPBDP). The proposed algorithm is implemented using Apache Hadoop (MapReduce) and Python.
Privacy preserving big data publishing: a scalable k-anonymization approach using MapReduce
A novel scalable approach based on k-anonymization is proposed for large volume of data in Privacy Preserving Big Data Publishing (PPBDP). The proposed algorithm is implemented using Apache Pig and Python over Apache Hadoop cluster. Based on empirical analysis it is found that the proposed approach have low information loss and very low running time as compared to existing approaches.
Towards Privacy Preserving Big Data Analytics
Discussion related to privacy issues with big data. Comparison of existing privacy preserving techniques with 3Vs of big data.
Privacy Preserving Unstructured Big Data Analytics: Issues and Challenges
Discussion related to privacy issues and challenges with respect to unstructured big data.
Watermarking for security in database: A review
A brief survey of database watermarking schemes.
A Novel approach as Multi-place Watermarking for Security in Database
Discussion related to database watermarking and existing techniques. Proposed a novel approach of inserting watermarking at two different places in database for copyright protection
