Abstract: A computer-implemented method of preparing an anonymised dataset for use in data analytics. The method includes the steps of: (a) labelling elements of a dataset to be analysed according to a labelling scheme; (b) selecting one or more labelled elements of the dataset to be replaced with a distance preserving hash; and for each selected element: (c) partitioning a data plane including the selected element into a plurality of channels, each channel covering a different distance space of the data plane; (d) hashing, using a cryptographic hash, data associated with the channel of the data plane in which the selected element resides, to form the distance preserving hash; and (e) replacing the selected element with the distance preserving hash.

Abstract: This disclosure includes systems and techniques that verify an educational quality of online videos, employing a platform that enables experts to endorse and/or recommend videos that are more readily accessible to end users. Certain aspects include a computing device for a service provider that receives a query from a user for video content. The computing device forwards the query to a hosting service, and in response to the query, the computing device receives, from the hosting service, a list of video content items it hosts. The computing device identifies, for each video content item within the list of video content items, an endorsement value associated with one or more experts. In some aspects, the computing device generates an aggregated list of video content items from a plurality of lists of video content items based on endorsement values. The computing device provides recommendations to the user using the endorsement values.
