View page
US Patent:
20080107039, May 8, 2008
Filed:
Nov 2, 2006
Appl. No.:
11/556075
Inventors:
Stilian A. Stoev - Ann Arbor MI, US
George Kollios - Cambridge MA, US
Murad S. Taqqu - Newton MA, US
International Classification:
H04J 1/16
US Classification:
370252, 370235
Abstract:
A method and apparatus for estimating dominance norms of a plurality of signals transmitted over networks are disclosed. For example, the present invention discloses a method and apparatus for estimating dominance norms of a plurality of signals using Max-stable distributions.

Verification Of Outsourced Data Streams

US Patent:
20100132036, May 27, 2010
Filed:
Nov 21, 2008
Appl. No.:
12/275879
Inventors:
George Kollios - Cambridge MA, US
Feifei Li - Tallahassee FL, US
Divesh Srivastava - Summit NJ, US
Ke Yi - Springfield NJ, US
Graham Cormode - Morristown NJ, US
Assignee:
AT&T Intellectual Property I, L.P. - Reno NV
International Classification:
G06F 21/00
G06F 17/30
US Classification:
726 22, 707E17108
Abstract:
Embodiments disclosed herein are directed to verifying query results of an untrusted server. A data owner outsources a data stream to the untrusted server, which is configured to respond to a query from a client with the query result, which is returned to the client. The data owner can maintain a vector associated with query results returned by the server and can generate a verification synopsis using the vector and a seed. The verification synopsis includes a polynomial, where coefficients of the polynomial are determined based on the seed. The data owner outputs the verification synopsis and the seed to a client for verification of the query results.

Efficiently Querying Databases While Providing Differential Privacy

View page
US Patent:
20190156057, May 23, 2019
Filed:
Nov 21, 2018
Appl. No.:
16/197813
Inventors:
Yaacov Nissim Kobliner - Kensington MD, US
Georgios Kellaris - Montreal, CA
George Kollios - Cambridge MA, US
International Classification:
G06F 21/62
G06F 17/30
Abstract:
Technologies are provided for efficiently querying a database using a plurality of oblivious random-access memories (ORAMs) while providing differential privacy. Subsets of a set of database records can be stored in a plurality of ORAMs. The subsets of database records in the separate ORAMs can be concurrently accessed (for example, by a database query server). When a database query is received, a number of database records that match the query can be identified for each of the ORAMs. A differential privacy constraint can be used to determine an additional number of database records to be retrieved from each ORAM. The differential privacy constraint can specify an upper bound on the number of records to be retrieved from each ORAM to prevent (or reduce the risk of) information leakage. Once all of the identified records are retrieved from the plurality of ORAMs, the additional records can be discarded.
