About Privitar SecureLink
Privitar SecureLink allows datasets about a pool of individuals taken from across a group of organisations (“contributors”) to be joined into combined datasets for analysis by a central organisation (the “recipient”).
Taken individually, many of the contributors (and indeed the recipient) may have constraints that make it impossible to share data with another contributor. For example, commercial issues such as competition, or industry-wide regulations may prohibit the sharing of identifiable data on individuals.
SecureLink allows each individual’s data, identified by a single type of direct identifier, to be joined at the recipient without revealing either the original identifier, or any party being able to join their data directly to any other party’s data.
This is achieved through the use of a homomorphic encryption protocol involving an intermediary party, which obscures the original ID value as it passes through the system, and ensures it is mapped deterministically to a new value at the recipient.
How to configure SecureLink
There are two parts to the configuration required to use SecureLink in Privitar.
Note
Please note that the configuration instructions given below assume that the required SecureLink server components are already available.
The configuration required is as follows:
Create appropriately configured Environments for the recipients. This action only needs to be performed once per recipient.
Create Jobs that the contributors and recipient will use day-to-day for pooling data via SecureLink.
