Vector: Query vector

Vector: Query vector

A query vector is a tokenized version of a query sequence for a given timeframe. This method is still work in progress. Focus has been on obfuscating the sequences to avoid re-identification of the client, which will limit the effectiveness of the analysis. The token space is deliberately small and tokens are generated by a hash function where collisions are to be expected. Any new tokens found are submitted with the vectors.
