Patent number: 10469486Abstract: Methods and apparatuses for authenticating communication devices and securely transmitting and/or receiving encrypted voice and data information. A biometric scanner, for example a fingerprint scanner, is utilized for authenticating the communication device and for generating the encryption key. The fingerprint scanner can be an area or swipe type of scanner is registered to a particular user and has unique intrinsic characteristics (the scanner pattern) that are permanent over time and can identify the scanner even among scanners of the same manufacturer and model. The unique scanner pattern of the scanner generates a unique encryption key that cannot be reproduced using another fingerprint scanner.Type: GrantFiled: April 8, 2017Date of Patent: November 5, 2019Assignee: UNIVERSITY OF MARYLANDInventors: John S. Baras, Vladimir Iankov Ivanov

Patent number: 9208370Abstract: Methods and apparatuses for authenticating a biometric scanner, such as swipe type finger print scanners, involves estimating unique intrinsic characteristics of the scanner (scanner pattern), that are permanent over time, and can identify a scanner even among scanners of the same manufacturer and model. Image processing and analysis are used to extract a scanner pattern from images acquired with the scanner. The scanner pattern is used to verify whether the scanner that acquired a particular image is the same as the scanner that acquired one or several images during enrollment of the biometric information. Authenticating the scanner can prevent subsequent security attacks using counterfeit biometric information on the scanner, or on the user authentication system.Type: GrantFiled: January 23, 2015Date of Patent: December 8, 2015Assignee: THE UNIVERSITY OF MARYLAND, COLLEGE PARKInventors: Vladimir Iankov Ivanov, John S.

Patent number: 9087228Abstract: Methods and systems involving image processing extract from an image and estimate unique intrinsic characteristics (scanner pattern) of a biometric scanner, such as area type fingerprint scanner. The scanner pattern is permanent over time, can identify a scanner even among scanners of the same manufacturer and model, and can be used to verify if a scanner acquired an image is the same as the scanner used for biometric enrollment, i.e., to authenticate the scanner and prevent security attacks on it. One method comprises selecting pixels from an enrolled and query image, masking useful pixels from the images, computing a similarity score between the common pixels of the enrolled and query useful pixels, and comparing this score with a threshold to determine whether the query image has been acquired by the same scanner as the enrolled image. The method can further comprise inverting the pixel values and/or filtering the selected pixels.Type: GrantFiled: January 23, 2015Date of Patent: July 21, 2015Assignee: THE UNIVERSITY OF MARYLAND, COLLEGE PARKInventors: Vladimir Iankov Ivanov, John S.
