Privitar products allow organisations to analyse datasets containing sensitive information (e.g. customer data, employee records, banking transactions, trade data) while preserving privacy or confidentiality. This opens up data for safe secondary use while ensuring consistent and accountable protection of private information.
Privitar Publisher generalises data to be resistant to linkage attacks whilst defending against the disclosure of an individual's senstive attributes. Multiple quasi-identifiers are generalised to achieve k-anonymity, in a way that automatically minimises distortion and so maximises the utility of the data for analytics and secondary use.
Taking a policy-oriented approach, Privitar Publisher's intutitive web interface allows you to centrally manage and action privacy policies with no need for scripting or custom coding. Policies are executed within your Hadoop cluster using the Spark framework, enabling high performance and scalability. Privitar Publisher is installed on-premise or in the cloud.
When sharing data outside your organisation, you lose control of how it might be accessed and further shared. This should be mitigated through contractual agreements, and also by using privacy technology to reduce the risk of data disclosure. Privitar Publisher allows you to:
Privitar Lens™ is a privacy-preserving query interface well suited for reporting and statistical analysis. Privitar Lens allows analysts to perform sophisticated analytical queries of the data (e.g. counts, sums, histograms), but prevents direct access to the underlying sensitive data.
Usage is subject to strict authentication and access control, and all queries are logged and audited. It allows data holders to post tables with their desired privacy controls for each analyst and for each column. Privacy controls are then dynamically applied to each query submitted.
Privitar Lens uses noise addition to prevent users from extracting private data, ensuring differential privacy. Further protection comes from behaviourial analytics for attack detection.
Privitar Lens tracks each query and calculates the total privacy risk across queries. It stops releasing new results after the privacy risk reaches a pre-defined threshold.
Privitar Lens has a number of features which make the product easy to use for non-privacy experts, including an intuititive web interface and REST API. It connects to data stores such as PostgreSQL or Hive with an extensible set of connector modules. Privitar Lens is installed on-premise or in the cloud.
Like security, privacy protection should be designed into data systems at every level, not bolted on as an afterthought. Privitar products add foundational privacy to your data processing architecture at every stage: ingest, data preparation, analytics, statistical modelling and reporting.
Companies may be unknowingly and unwillingly leaking sensitive information in non-obvious ways as the use of data for secondary purposes expands. Privitar is providing products that integrate neatly with Cloudera Enterprise, the leading open source data management platform based on Apache Hadoop.
Privacy matters: One solution, on the privacy side at least, is to separate the identity of the person being measured by a sensor from the data they generate. John Taysom, a fellow of the University of Cambridge and co-founder of privacy company Privitar, believes this “disassociation” is key because companies and governments get the data without a risk to privacy.
It is essential that we develop practical ways of protecting privacy, otherwise we may not be able to sustain growth in the internet based economy.
Privacy is a game changer; it will be to organizations in 2016 what websites were to companies in 2000. So this is the year to up the ante on your investments: you need the right cross-functional team, good governance practices, and the technical tools to ensure that all of your systems are in compliance with both laws and internal privacy guidelines. Making the right investments will let your firm drive business growth, win new customers, and build deeper customer relationships.
