Publication number: 20190141029Abstract: An invention is provided for authentication in a network environment. The invention includes displaying an authentication image on a display device, and generating a captured image by capturing an image using a client device. The image is captured through an optical element capable of rotating the image as viewed from the client device, such as a dove prism. The captured image then is analyzed to determine color band values of selected pixels of the captured image. Once analyzed, a comparison result is generated by comparing the color band values the selected pixels of the captured image to color band values of corresponding pixels of the authentication image. If the comparison result is within a predetermined threshold authentication is provided.Type: ApplicationFiled: August 21, 2018Publication date: May 9, 2019Applicant: Digital Authentication Technologies, Inc.Inventor: Roger R Dube

Publication number: 20170132405Abstract: An invention is provided for establishing the provenance of data, devices, and commands. The invention includes collecting contextual information characterizing a specific location during a first time period utilizing a contextual data collection device. A contextual location fingerprint is then created based on the collected contextual information. Later, such as when data is to be created and transferred to another system, new contextual information is collected at the location occupied by data to be verified during a second time period, such as during installation. A certificate of provenance is generated utilizing the collected new contextual information, and embedded into the data. Later, for example during installation, the information within the certificate of provenance is compared to the CLF, and authenticated if the information is within predefined parameters of the CLF.Type: ApplicationFiled: June 24, 2016Publication date: May 11, 2017Applicant: Digital Authentication Technologies, Inc.Inventor: Roger R.

Patent number: 7231044Abstract: An invention for digital authentication is provided. A first timing signal is received from a remote source using a receiver. Next, a delay number is stored. The delay number is based on a first delay time period between when the first timing signal was transmitted and when the first timing signal was received. A digital transaction is then authenticated using the delay number. In one aspect, a digital certificate is created using the delay number. The remote source can be any source capable of generating timing signals, such as a global positioning satellite (GPS) system or a cell tower system. The delay in the timing signal can be caused by free electrons in a line of sight between the remote source and the receiver, such as by variations in atmospheric conditions or by an object within the line of sight such as bird or tree branch. Optionally, the delay number can be stored on a User Card and a System Card.Type: GrantFiled: September 7, 2001Date of Patent: June 12, 2007Assignee: Digital Authentication Technologies, Inc.Inventor: Roger R.

Patent number: 5535871Abstract: A security thread for documents such as currency and banknote paper comprises a plastic substrate coated with a plurality of discrete metallic patterns of electrically-conductive material, such as aluminum. The metallic patterns are arranged on the surface of the thread to indicate the particular denomination of the currency paper. The thread is typically embedded entirely with the currency paper. A first embodiment of a verification device determines the authenticity and denomination of the currency paper by counting the number of conductive metallic patterns on the thread and comparing the count to various count ranges. A second embodiment of the verification device scans the thread in a narrow-edge direction such that it simultaneously encounters all of the conductive thread segments. Capacitive coupling of an oscillator signal into one or more sensing pads result in an electrical signal having a distinct pattern.Type: GrantFiled: August 29, 1995Date of Patent: July 16, 1996Assignee: Authentication Technologies, Inc.Inventor: Steven K.

Patent number: 5419424Abstract: A currency paper has a security thread embedded therein. The thread comprises a plastic substrate having a plurality of alphanumeric, metallic, electrically-conductive characters formed thereon. The characters have predetermined heights and widths and spacings therebetween. The verification device comprises an oscillator electrode and associated horizontal and vertical electrodes. A time-varying oscillator signal is coupled to the oscillator electrode. The spacing of the horizontal and vertical electrodes in relation to the oscillator electrode is determined by the spacing between the metallized characters on the thread. A valid security thread capacitively couples the oscillator signal into the horizontal electrode but not the vertical electrode. On the other hand, a counterfeit security thread will couple the oscillator signal into both the horizontal and vertical electrodes. Signal processing electronics is provided to sense these valid and counterfeit conditions.Type: GrantFiled: April 28, 1994Date of Patent: May 30, 1995Assignee: Authentication Technologies, Inc.Inventor: Steven K.

Patent number: 5417316Abstract: A verification device for a security thread embedded within currency paper includes two or more sensor channels, each channel comprising a sensor plate and a guard plate disposed adjacent to one another. The sensor plate and guard plate of one channel are in a planar relationship with the sensor plate and guard plate of all other channels. A transistor has its base connected to the sensor plate and its emitter connected to the guard plate, thereby effectively removing any stray capacitance between the sensor and guard plates. The output of the transistor at its emitter is indicative of the amount of the electrical charge on the sensor plate. Signal processing electronics disposed after the transistor convert the sensor plate capacitance into an electrical signal whose pulse width is proportional to the amount of sensor plate capacitance. A valid currency having a security thread embedded therein passes by a sensor plate and varies the amount of capacitance of the plate.Type: GrantFiled: March 18, 1993Date of Patent: May 23, 1995Assignee: Authentication Technologies, Inc.Inventor: Steven K.

Patent number: 5394969Abstract: A verification device for a security thread embedded within currency paper includes a pair of capacitive plates having applied thereto time-varying electronic signals that are 180.degree. out of phase. Disposed between the plates is a sensor element comprising a cylindrical wire dimensionally equal to the security thread. A guard electrode surrounds the sensor; the guard, sensor, and plates comprising a capacitance bridge. When the security thread in the currency is adjacent to the sensor and in proximity thereto, a capacitance imbalance occurs in the bridge. Electronic circuitry is responsive to this imbalance and provides an indication of a valid security thread embedded within the proffered currency paper.Type: GrantFiled: March 8, 1993Date of Patent: March 7, 1995Assignee: Authentication Technologies, Inc.Inventor: Steven K.
