An apparatus, system and method are introduced for preserving privacy of data in a dataset in a database with a number n of entries. In one embodiment, the apparatus includes memory including computer program code configured to, with a processor, cause the apparatus to form a random matrix of dimension m by n, wherein m is less than n, operate on the dataset with the random matrix to produce a compressed dataset, form a pseudoinverse of the random matrix, and operate on the dataset with the pseudoinverse of the random matrix to produce a decompressed dataset.

Privacy-preserving aggregated data mining

In an OCDM-based photonic encryption system by applying random noise on unused channels and varying the inter-code phases on realistic framing repetition, an OCDM-based encryption system with provable security guarantees results.

OCDM-based photonic encryption system with provable security

A system, and method related thereto, for providing a vehicular communications network public-key infrastructure. The system comprises a plurality of communications infrastructure nodes and a plurality of vehicles each having a communications component. The communications component provides vehicle to vehicle (V2V) communications, and communications via infrastructure nodes. A communications security component in each of the plurality of vehicles provides security for the communications between the plurality of vehicles using a plurality of security modules. The security modules include a certificate management module. A public key interface module may include a public key, a private key, an anonymous key and a management key. The system further includes a detection and response module for attack detection and attack mitigation. The communications security component assigns and installs at least one security key, a certificate of operation, and a current certificate revocation list. The communications component provides secure communications between the plurality of vehicles.

Method for a public-key infrastructure for vehicular networks with limited number of infrastructure servers

A method and software product for limit privacy loss due to data shared in a social network, where the basic underlying assumptions are that users are interested in sharing data and cannot be assumed to constantly follow appropriate privacy policies. Social networks deploy an additional layer of server-assisted access control which, even under no action from a user, automatically evolves over time, by restricting access to the user's data. The evolving access control mechanism provides non-trivial quantifiable guarantees for formally specified requirements of utility (i.e., users share as much data as possible to all other users) and privacy (i.e., users expose combinations of sensitive data only with low probability and over a long time).
