Finding optimal solutions to Web Service Location Allocation Problem (WSLAP) using exhaustive algorithms and exact approaches is not practical. Computational time required to solve WSLAP using exact approaches increases exponentially with the problem size. The disclosure herein generally relates to service deployment, and, more particularly, to a method and system for web service location allocation and virtual machine deployment. The system identifies a plurality of web-services that are associated with the WSLAP and then decomposes the WSLAP to a plurality of sub-problems. For each sub-problem, the system determines at least one non-dominating solution, which are then merged to generate the solution for the WSLAP. The generated solution to the WSLAP can be used for perform Virtual Machine (VM) deployment under uncertainties, using a stochastic approach, wherein the uncertainties refer to dynamic change in requirements in terms of parameters such as but not limited to configuration, and cost.

This disclosure relates generally to data anonymization using clustering techniques. In Typically, data anonymization using global recoding can overgeneralize the data. However, preservation of information while anonymization the data is of equal importance as obscuring the relevant information that can be used by the attackers. The disclosed method and system utilized attribute taxonomy tree for generalization to optimize the generalization of the records. The disclosed method uses clustering-based approach and after clustering, each cluster is solved independently using ILP model for K-Anonymization. The ILP model is solved by generalizing the value of the attributes. Sometimes, even after clustering the number of possible patterns is large, thus the disclosed method generates patterns on the fly during multiple iterations.

This disclosure relates generally to data anonymization and more particular y risk-aware data anonymization. Conventional data anonymization systems either replace PII/sensitive attributes with random values or shuffles them, that causes huge data distortion affecting the data utility. The goal of publishing data is best achieved when privacy is balanced with utility of data, Moreover, to ensure privacy, assessing the risk of disclosure is important. The proposed system provides a pipeline for analysis of data patterns to understand the associated risk level of re-identification of records. Further, based on the identified risks with the records the system anonymizes the data following a pattern based anonymization approach wherein data is clustered and for each cluster distinct patterns are identified such that the information loss is minimal.

This disclosure relates generally to selection of cloud service providers in a multi-cloud. The selection of cloud service providers (CSPs) in a multi-cloud environment is challenging as it depends on multiple criteria such as security, usability, latency, and service cost. In an embodiment, for each CSP and multi-CSP combination, two decision problems are solved; namely, a VM selection problem and a cloud region selection problem, taking latency requirement and DR laws constraints into consideration. By solving the VM selection and CC selection problems, the service cost and the user to cloud region mapping are estimated. Using said estimates and other qualitative criteria, a multi-cloud multi-criteria decision problem is solved using MCDM techniques to rank the CSP combinations for each application. Based on the ranks and a constraint on a service cost of the entity one of a CSP and a CSP combination is selected for each application.

Data is an asset to any organization and any breach to the data during task allocation to agents may lead to serious damage to organizations including loss of consumer confidence, trust, reputation, financial penalties and the like. Conventional methods mainly focus on the allocating task to agents based on user satisfaction, overall throughput and maximize revenue and less focus is given to data privacy. The present subject matter overcomes the limitations of the conventional methods for task allocation by utilizing a dynamic data exposure analysis method, which enables seamless upgrading of the data access policy and or control. Here, a data exposure is monitored based on a data exposure score, dynamic identification of conflicting tasks and a dynamic privacy budget. The data exposure score is calculated in two execution points. Finally all the values are updated in the system for utilization in the further privacy enabled task allocation.
