Protect

WITDOM’s Secure Signal Processing (SSP) component performs secure signal processing operations on protected data and signals (encrypted, obfuscated, split or a combination thereof) in an untrusted environment, by preventing the disclosure of the sensitive information while it is being processed in the untrusted domain.

WITDOM’s data masking component is responsible for masking sensitive data classified as direct identifiers. The masking process creates service-and-user-specific tokens that can be updated over time, satisfying two main security requirements: irreversibility and unlinkability.

This tool provides the means for processing data in different ways, supporting different purposes with different privacy requirements. It includes several components providing the capabilities to encrypt data while preserving the format or ordering of the data. This tool enables users of legacy applications to move their databases to a public cloud, while preserving data privacy and confidentiality. Moreover, the tool provides components for data generalization as means for anonymizing bulk data using k-anonymity techniques.

"PRISMACLOUD Tools: A cryptographic toolbox for increasing security in cloud services. reusable toolbox encapsulating cryptographic functionality from which dependably secure cloud services can be assembled. In order to provide a tangible abstraction of the complexity involved with the construction of cryptographically secured cloud services, we introduce the fourlayer PRISMACLOUD architecture. Top down, it consists of a use cases (application) layer, a services layer, a tools layer, and a cryptographic primitives and protocols layer.
