N1 Analytics

HOW DOES N1 ANALYTICS WORKAND WHAT CAN IT DO?

HOW DOES IT WORK?N1 uses 3 cutting edge technologies that enable analytics on alternative data while:

STAYING COMPLIANT OF POLICIES AND LEGISLATION

KEEPING EVERYBODY’S DATA SAFE

DOING IT IN A COST EFFECTIVE MANNER

3 TECHNOLOGIES

1HOMOMORPHIC

ENCRYPTION

2DISTRIBUTED COMPUTING

3PRIVACY PRESERVING

RECORD LINKAGE

Encrypt(5) = #jdao

HOMOMORPHIC ENCRYPTIONHomomorphic encryption is a form of encryption that allows computations to be carried out on encrypted data, thus generating an encrypted result which, when decrypted, matches the result of operations performed on the original unencrypted data.

5 X 3 = 15

Encrypt(5) = #jdao

Encrypt(3) = #hdah

#jdao X #hdah = #onda

Decrypt(#onda) = 15

DISTRIBUTED COMPUTINGThe N1 Solution uses a form of distributed computing where the computation goes to where the datasets reside instead of moving the data around.

Let’s look at an example to understand Privacy Preserving record linkage.

Say you have a dataset which you would like to combine with data owned by another company.

… and converts them to a bunch of hashes. This is done so that even N1 cannot know the details of those fields.

N1

It then uses fuzzy matching to match the hashes and find the common records.

Next, N1 rearranges the records so they line up with their corresponding rows.

Where records do not match up, N1 will create dummy data so neither party will know which records exist in the other’s dataset.

What you effectively get is an enhanced dataset but one where the data never leaves its premises. This means that none of the parties, including N1, can ever see each other’s data. We call this Privacy Preserving record linking.

Now that the enhanced dataset is ready, the user can then select an algorithm to start the computation.

N1 uses distributed computing to send the algorithm to the first dataset and start the computation.

N1 then uses a number of techniques including homomorphic encryption to encrypt the results before sending them to the next dataset.

Finally the the results can be decrypted and presented back to the N1 user.

A second way that N1 can be used is to expand your data.

Say you have a dataset and want to expand the number of records by combining it with another dataset.

You can use N1 to match up the common columns so you can extend the number of rows.

The algorithm can then move between the datasets to train a model which gives superior insights than one trained on limited data.
