For situations where privacy is paramount, homomorphic encryption provides a mechanism that enables a user to share information to a third party — who can carry out computations on that data — while maintaining confidentiality.
What is it?
Homomorphic encryption is a method of allowing certain operations on data while never revealing the actual data itself.
We are starting to see that these systems are able to deliver adequate performance levels that make them a feasible option for scenarios where privacy is paramount.
What’s in for you?
Trust in your businesses’ data and how it is used — both from a functional and ethical standpoint — has always been important. But going forward, it will be a commercial and moral imperative.
Your brand strength relies on keeping data safe. Moreover, new trust-first business models can be established that build on the outsourced compute model that homomorphic encryption facilitates.
What are the trade offs?
New styles of encryption, such as homomorphic encryption, will fundamentally change the way in which users and consumers access your systems.
You may need to change the way your systems before consumers can make use of this technology — either by modifying your existing applications or perhaps the introduction of specialized client-server applications that can deliver the necessary functionality to make this work. This could add costs to your business.
