Printed or imaged documents can be marked using handwritten signature images, seal images, electronic fingerprinting, watermarking, and / or steganography. Electronic commercial transactions and transmissions take place in a reliable, "trusted" virtual distribution environment that provides significant efficiency and cost savings benefits to users in addition to providing an extremely high degree of confidence and trustedness. The systems and techniques have many uses including but not limited to secure document delivery, execution of legal documents, and electronic data interchange (EDI).

The present invention provides systems and methods for authenticating access requests from user devices by presenting one of a plurality of graphical user interfaces selected depending on a perceived risk of fraud associated with the devices. User devices are identified with fingerprinting information, and their associated risks of fraud are determined from past experience with the device or with similar devices and from third party information. In preferred embodiments, different graphical user interfaces are presented based on both fraud risk and, in the case of a known user, usability. In preferred embodiments, this invention is implemented as a number of communicating modules that identify user devices, assess their risk of fraud, present selected user interfaces, and maintain databases of fraud experiences. This invention also includes systems providing these authentication services.

A method for recognizing an audio sample locates an audio file that most closely matches the audio sample from a database indexing a large set of original recordings. Each indexed audio file is represented in the database index by a set of landmark timepoints and associated fingerprints. Landmarks occur at reproducible locations within the file, while fingerprints represent features of the signal at or near the landmark timepoints. To perform recognition, landmarks and fingerprints are computed for the unknown sample and used to retrieve matching fingerprints from the database. For each file containing matching fingerprints, the landmarks are compared with landmarks of the sample at which the same fingerprints were computed. If a large number of corresponding landmarks are linearly related, i.e., if equivalent fingerprints of the sample and retrieved file have the same time evolution, then the file is identified with the sample. The method can be used for any type of sound or music, and is particularly effective for audio signals subject to linear and nonlinear distortion such as background noise, compression artifacts, or transmission dropouts. The sample can be identified in a time proportional to the logarithm of the number of entries in the database; given sufficient computational power, recognition can be performed in nearly real time as the sound is being sampled.

This invention provides an apparatus and method for analyzing a polynucleotide sequence; either an unknown sequence or a known sequence. A support, e.g. a glass plate, carries an array of the whole or a chosen part of a complete set of oligonucleotides which are capable of taking part in hybridization reactions. The array may comprise one or more pair of oligonucleotides of chosen lengths. The polynucleotide sequence, or fragments thereof, are labelled and applied to the array under hybridizing conditions. Applications include analyses of known point mutations, genomic fingerprinting, linkage analysis, characterization of mRNAs, mRNA populations, and sequence determination.

A method for authenticating a chain of custody utilizing blockchain technology, whereby digital evidence or other digital content is acquired and then hashed to produce a hash fingerprint / signature and then immediately or instantly submitting said hash fingerprint / signature to the blockchain using the blockchain network protocol, forming an immediate verifiable chain of custody without human interaction or requiring a trusted third party.

Techniques for fraud monitoring and detection using application fingerprinting. As used herein, an “application fingerprint” is a signature that uniquely identifies data submitted to a software application. In an embodiment, a plurality of historical application fingerprints are stored for data previously submitted to a software application. Each historical application fingerprint is associated with one or more contexts in which its corresponding data was submitted. When new (i.e., additional) data is subsequently submitted to the application, a new application fingerprint is generated based on the new data, and the new application fingerprint is associated with one or more contexts in which the new data was submitted. The new application fingerprint is then compared with one or more historical application fingerprints that share the same, or substantially similar, context(s). Based on this comparison, a risk score is generated indicating a likelihood that the new data was submitted for a fraudulent / malicious purpose.

A fingerprint-reading system includes a fingerprint sensor having an active surface sensitive to the pressure and temperature of a finger. The surface area of this sensor is far smaller than the surface area of the fingerprint to be read. The reading is done when the sensor and the finger are in contact and in a relative motion of sliding of the sensor and the finger with respect to each other. The system reconstitutes a complete image of the fingerprint from the partial images given by the sensor during this motion.

Methods, systems, and configured storage media are provided for discovering software updates, discovering if a given computer can use the software update, and then updating the computers with the software as needed automatically across a network without storing the updates on an intermediate machine within the network. Furthermore, when a failure is detected, the rollout is stopped and the software can be automatically removed from those computers that already were updated. The software update can be stored originally at an address that is inaccessible through the network firewall by intermediately uploading the software update to an update computer which is not a part of the network but has access through the firewall, which is then used to distribute the update.

By including environment information in a security policy, a security architecture advantageously allows temporal, locational, connection type and / or client capabilities-related information to affect the sufficiency of a given credential type (and associated authentication scheme) for access to a particular information resource. In some configurations, time of access, originating location (physical or network) and / or connection type form a risk profile that can be factored into credential type sufficiency. In some configurations, changing environmental parameters may cause a previously sufficient credential to become insufficient. Alternatively, an authenticated credential previously insufficient for access at a given trust level may be sufficient based on a changed or more fully parameterized session environment. In some configurations, the use of session tracking facilites (e.g., the information content of session tokens) can be tailored to environmental parameters (e.g., connection type or location). Similarly, capabilities of a particular client entity (e.g., browser support for 128-bit cipher or availablity of a fingerprint scanner or card reader) may affect the availability or sufficiency of particular authentication schemes to achieve a desired trust level.

In one embodiment, the present invention is a method and apparatus for wireless network security. In one embodiment, a method for securing a wireless computing network includes receiving a communication from an unidentified transmitter, identifying the transmitter in accordance with a fingerprint generated from one or more radio frequency signal characteristics extracted from the communication, and taking action in response to an identity of the transmitter.

This invention is directed to an electronic device with an embedded authentication system for restricting access to device resources. The authentication system may include one or more sensors operative to detect biometric information of a user. The sensors may be positioned in the device such that the sensors may detect appropriate biometric information as the user operates the device, without requiring the user to perform a step for providing the biometric information (e.g., embedding a fingerprint sensor in an input mechanism instead of providing a fingerprint sensor in a separate part of the device housing). In some embodiments, the authentication system may be operative to detect a visual or temporal pattern of inputs to authenticate a user. In response to authenticating, a user may access restricted files, applications (e.g., applications purchased by the user), or settings (e.g., application settings such as contacts or saved game profile).

A pointing device incorporates a biometric sensor at a location such that when operating the pointing device in a normal manner, a user's hand rests naturally in a position to place a finger of the user's hand in proximity to and readable by the biometric sensor. In one embodiment, a computer trackball pointing device includes a fingerprint sensor which is equally well suitable for use by either a right-handed or a left-handed user. Along with positional information from a position sensor and user selection information from at least one user-depressable button, the pointing device also conveys to an attached computer system information associated with the user's identity detected by the fingerprint sensor. Such a pointing device is well suited to both transparent verification as well as continuous verification, for if a user removes his or her hand from the natural position when using the device, the user's fingerprint will no longer be detectable by the fingerprint sensor, and the computer system to which the pointing device is attached can be alerted as to the need to re-authenticate any additional attempts at using the pointing device.

The present invention provides a home security system that includes a home security controller for collecting monitor data from various crime prevention and disaster prevention sensors installed in a home via a home network and notifying the portable terminal when a state of emergency occurs. The home security controller also enables devices in the home to be operated through remote control signals via an external network. The home security system further includes a portable terminal capable of connecting to the external network and having fingerprint data inputting means mounted on the body of the portable terminal for inputting fingerprints used for authentication. The fingerprint data inputting means has an assigned ID number. The home security system further includes a security center server having fingerprint authenticating means for receiving fingerprint data from the portable terminal via the external network and authenticating the fingerprint data through comparisons with registered fingerprint data. The fingerprint authenticating means completes authentication by checking the assigned ID number of the fingerprint data inputting means and matching the received fingerprint data with fingerprint data registered in association with the ID number. The security center server allows a connection between the portable terminal and the home security controller and controls bi-directional communications between the two after the security center server has completed authentication, enabling the portable terminal to receive monitor data from and transmit remote control signals to the home security controller via the external network.

Interactive digital media platform, methods and apparatus for detecting and dynamically synchronizing to media content (e.g., television (TV) programs or movies) that a viewer is watching while providing related content on a second screen for enhancing the viewer experience. In one embodiment, the primary content is determined by detecting an audio signal of the primary content via the second screen device; the audio signal may then be processed to generate a fingerprint for comparison with a data store of primary content. The primary content can be classified by various categories (e.g., unique program, advertising, repeat airing, theme song . . . ) and the classification used to aid in the identification and / or in selection of the content to be presented on the interactive second screen device. The system allows a substantially real time comparison and recognition of what primary content a viewer is watching on a first screen device and presentation to the user of content that is substantially synchronous to the viewer's location in the primary content. The viewer can actively engaged with the content presented and can share the content with others via social networking and the like.

A method for authenticating an individual by use of fingerprint data that involves two different broad steps. The first step is to obtain a biometrics fingerprint signature template (“BFST”) for an individual in an enrollment process by selecting a plurality of bands for the BFST and obtaining a plurality of tracks corresponding to each of the plurality of bands by use of an enrollment frame of a selected finger of the individual, wherein the plurality of bands are spatially referenced to the enrollment frame and can be spatially referenced to a reference barrier. The second step is to authenticate (or not) a candidate finger against one or more BFST in an authentication process in which a swipe direction and an access code for the individual are selected, a plurality of candidate tracks are obtained from the candidate finger through use of the reference barrier in an authentication unit so that each of the plurality of candidate tracks is spatially referenced so as to be within a corresponding one of the plurality of bands, calculating a similarity index for each of the plurality of candidate tracks and each of the plurality of tracks for the band to which the candidate track corresponds by use of a Fast Fourier-transform fingerprint algorithm, and multiplying each maximum similarity index obtained for each of the plurality of candidate tracks to obtain a match index which indicates a match if it exceeds a preselected threshold.

Several novel watermarking and fingerprinting applications—and related improvements—are disclosed. Some relate to advertising. These include techniques for replacing broadcast advertising with other advertising; inserting advertising based on a viewer's ad-viewing history; triggering insertion of advertising based on fingerprint data derived from compressed video content; and discontinuing advertising when a threshold amount of advertising has apparently been viewed. A great number of other features and technologies are also detailed.

A machine includes a processor and a memory connected to the processor. The memory stores instructions executed by the processor to receive a message with audio content and video content. Audio fingerprints within the audio content are evaluated. The audio fingerprints are matched to known audio fingerprints to establish matched audio fingerprints. A determination is made whether the matched audio fingerprints correspond to a designated gallery constructed to receive a sequence of videos set to an audio time line. The matched audio fingerprints and corresponding video content are added to the audio time line. The operations are repeated until the audio time line is populated with corresponding video content to form a completed gallery with video segments set to audio segments that constitute a complete audio time line. The completed gallery is supplied in response to a request.

The smart card with random temporary account number generation provides an authenticating system coupled with an access or transaction card, such as a credit card. The card includes first and second memory storage media, with the first memory medium containing a plurality of temporary account or authentication numbers.

A biometric method and system for personal authentication using sequences of partial fingerprint signatures provides a high security capability to various processes requiring positive identification of individuals. This approach is further enhanced by employing a frequency domain technique for calculating a Similarity Index of the partial fingerprint signatures. In a baseline usage, the sequential partial fingerprint sequence techniques augments sentinel systems for gaining access to restricted areas, and when used in combination with financial cards, offer a unique and greatly simplified means for authenticating or identifying individuals. A highly automated technique initially obtains four (illustratively) linear partial fingerprint signatures which serve as reference data against which later proffered candidate data in the form of at least two linear partial fingerprint signatures are compared for authentication. The particular two candidate signatures used and the sequence in which they are submitted are selected with the user's consent and serve as a PIN-like unique personal code. In an advanced embodiment, the same two candidate signatures in the chosen sequence are processed in a unique FFT / DFT process to produce a highly reliable Similarity Index to authenticate or verify the identity of individuals. The use of only partial fingerprint data greatly allays the concerns of widespread fingerprint dissemination by many individuals.

An integrated circuit identification device (ICID) to be incorporated into an integrated circuit (IC) includes an array of electronic cells in which the magnitude of an output signal of each cell is a function of randomly occurring parametric variations which vary from cell-to-cell. The ICID also includes a circuit for measuring the output of each cell and for producing output data having a value reflecting the particular combination of measured characteristics of all of the elements of the array. When we make the number of elements in the array large enough, we insure that to a high degree of probability, the pattern of measured array cell characteristics for an ICID embedded in any one IC will be unique and distinguishable from such patterns measured by ICIDs embedded in millions of other ICs. Thus the value of the output data produced by an ICID circuit acts as a unique "fingerprint" for the IC in which it is installed, and can be used as a unique identification (ID) for that IC.

Content segmentation, categorization and identification methods are described. Content tracking approaches are illustrated that are suitable for large scale deployment. Time-aligned applications such as multi-language selection, customized advertisements, second screen services and content monitoring applications can be economically deployed at large scales. A client performs fingerprinting, scene change detection, audio turn detection, and logo detection on incoming video and gathers database search results, logos and text to identify and segment video streams into content, promos, and commercials. A learning engine is configured to learn rules for optimal identification and segmentation at each client for each channel and program. Content sensed at the client site is tracked with reduced computation and applications are executed with timing precision. A user interface for time-aligned publishing of content and subsequent usage and interaction on one or more displays is also described.

A transaction automation and archival system is provided for controlling, real-time logging, and archiving complex commercial transactions such as the purchase and financing of an automobile. The heart of the system is an electronic contract disclosure unit, or ECDU. The ECDU includes a digitizing display that includes a video display for imaging to participants the various documents involved in the transaction and a digitizer for allowing participants to sign, indicate choices, and otherwise interact directly on documents and images presented on the display. A computer controls the entire progress of the transaction, and thus controls the collaborative space occupied by the participants to the transaction. The computer, for instance, controls the order of presentation of documents to a vehicle purchaser, receives the purchaser's signature on the displayed documents when required, offers choices of various packages that can be accepted or declined by the purchaser, and insures that the entire transaction is carried out properly. The ECDU further logs the transaction for future review and preferably includes a video camera and microphone for logging images and sounds of the participants during the transaction. One or more fingerprint readers are associated with the digitizing display for allowing participants to select between options by pressing their thumb or finger on the reader, which simultaneously verifies the identity of the individual making the selection through the fingerprint.
