Privacy-Preserving Behavior Targeting For Digital Coupons

US Patent:

20130159192, Jun 20, 2013

Filed:

Dec 16, 2011

Appl. No.:

13/329020

Inventors:

Kurt Partridge - Palo Alto CA, US
Ersin Uzun - Mountain View CA, US
Cong Wang - Chicago IL, US
Manas Ashok Pathak - Pittsburgh PA, US

Assignee:

PALO ALTO RESEARCH CENTER INCORPORATED - Palo Alto CA

International Classification:

G06Q 30/02
H04L 9/28

US Classification:

705 50, 705 141

Abstract:

A smart coupon-delivery system provides targeted coupons to a user using a criteria-encoded message received from a coupon server. The criteria-encoded message is generated by the coupon server from a behavior-criteria vector that indicates criteria for selecting a recipient of a digital coupon. The system then generates a user-behavior vector to indicate one or more behavior patterns of an end-user, and encodes the user-behavior vector to produce a behavior-encoded message. The system then determines whether the end-user is eligible to receive the digital coupon based on the criteria-encoded message and the behavior-encoded message. If the system determines that the end-user is eligible, the system presents the digital coupon to the end-user.

Transaction Verification On Rfid Enabled Payment And Transaction Instruments

US Patent:

20130179349, Jul 11, 2013

Filed:

Mar 1, 2013

Appl. No.:

13/782764

Inventors:

The Regents of the University of California - Oakland CA, US
Ersin Uzun - Irvine CA, US

Assignee:

THE REGENTS OF THE UNIVERSITY OF CALIFORNIA - Oakland CA

International Classification:

G06Q 20/32

US Classification:

705 44

Abstract:

A display enabled RFID tag (DERT) receives transaction details from the reader. DERT verifies that the details match their counterparts in the reader public key certificate. The process is aborted in case of a mismatch. DERT extracts and displays user-verifiable data. It then enters a countdown stage that lasts for a predetermined duration. A user observes the transaction information and, if the transaction amount and other details are deemed correct, presses an accept button provided on the DERT before the timer runs out. DERT signs the time-stamped transaction statement and sends it to the reader. This signed statement is then sent to the payment gateway and eventually to the financial institution that issued the payment DERT.

Computer-Implemented System And Method For Protecting Sensitive Data Via Data Re-Encryption

US Patent:

20170366519, Dec 21, 2017

Filed:

Jun 17, 2016

Appl. No.:

15/185575

Inventors:

- Palo Alto CA, US
Shantanu Rane - Menlo Park CA, US
Ersin Uzun - Campbell CA, US
Alejandro E. Brito - Mountain View CA, US

International Classification:

H04L 29/06
G06F 17/30

Abstract:

A computer-implemented method for protecting sensitive data via data re-encryption is provided. Encrypted data is maintained. A data query is received from a user associated with a public key and a secret key. Results of the query are computed by identifying at least a portion of the encrypted data and by adding plaintext for the identified portion of the encrypted data as the results. A re-encryption key is generated for the results using the public key of the user and the results are re-encrypted using the re-encryption key. The re-encrypted results are then transmitted to the user.

System For Key Exchange In A Content Centric Network

US Patent:

20170366526, Dec 21, 2017

Filed:

Aug 30, 2017

Appl. No.:

15/690485

Inventors:

- San Jose CA, US
Marc E. Mosko - Palo Alto CA, US
Ersin Uzun - Campbell CA, US

International Classification:

H04L 29/06
H04L 9/08
H04W 12/04

Abstract:

One embodiment provides a system that facilitates secure communication between computing entities. During operation, the system generates, by a content-consuming device, a first key based on a first consumer-share key and a previously received producer-share key. The system constructs a first interest packet that includes the first consumer-share key and a nonce token which is used as a pre-image of a previously generated first nonce, wherein the first interest has a name that includes a first prefix, and wherein the first nonce is used to establish a session between the content-consuming device and a content-producing device. In response to the nonce token being verified by the content-producing device, the system receives a first content-object packet with a payload that includes a first resumption indicator encrypted based on a second key. The system generates the second key based on a second consumer-share key and the first content-object packet.

Computer-Implemented System And Method For Automatically Identifying Attributes For Anonymization

US Patent:

20170124336, May 4, 2017

Filed:

Nov 3, 2015

Appl. No.:

14/931802

Inventors:

- Palo Alto CA, US

G06F 17/27
G06F 21/62
H04L 29/06

Abstract:

A computer-implemented system and method for automatically identifying attributes for anonymization is provided. A dataset of attributes is accessed. Each attribute in the dataset is associated with a plurality of values. The values of the dataset are encrypted and the attributes are processed by assigning a sensitivity level to each of the attributes. One or more of the attributes are selected from the dataset for anonymization based on the assigned sensitivity levels.

Computer-Implemented System And Method For Analyzing Data Quality

US Patent:

20160352693, Dec 1, 2016

Filed:

Aug 8, 2016

Appl. No.:

15/231689

Inventors:

- Palo Alto CA, US
Shantanu Rane - Menlo Park CA, US
Alejandro E. Brito - Mountain View CA, US
Ersin Uzun - Campbell CA, US

International Classification:

H04L 29/06

Abstract:

A computer-implemented system and method for analyzing data quality is provided. Attributes each associated with one or more elements are maintained. A request from a user is received for determining data quality of at least one attribute based on an interest vector having a listing of the elements of that attribute and a selection of elements of interest. Each element is encrypted. A condensed vector having the same listing of elements as the interest vector is populated with occurrence frequencies for each of the listed elements. The elements of the condensed vector are encrypted by computing an encrypted product of each element in the condensed vector and the corresponding element of the interest vector. An aggregate is determined based on the encrypted products of each element of the interest vector and the corresponding element of the condensed vector. The aggregate is provided as results of the data quality.
