Methods and Apparatus for Software Defined Access (SDA) for Het Nets

Software Defined Access (“SDA”) is a network architecture for heterogeneous networks that extends the concept of software defined networking for the core network to mobile devices connected at the network edge. SDA integrates various data networks available to mobile devices into a virtual network infrastructure and provides a logical control path to mobile devices. The logical control path enables the SDA architecture to dynamically configure mobile devices and the flows associated with them. Moreover, SDA provides mechanisms to learn the unknown and time-varying underlying network states as well as user preferences. This information is then used to optimize network performance by adaptively configuring flow paths. The proposed SDA architecture design is independent of network operators and underlying wireless technologies.


Method And Apparatus For Dynamic Spectrum Access

Apparatus and methods are disclosed for improving wireless and other network communications, e.g., through improving resource utilization, which may comprise the steps of accumulating channel modeling information relating to channel performance; calculating a channel parameter threshold based on the accumulated channel modeling information, whereby the channel parameter, as measured, being above the threshold indicates the channel is a good channel; adjusting traffic over a selected good channel to improve performance of the network or a network resource. The network resource may comprises battery life for devices operating on the network, data rate for devices operating on the network, constituting or reconstituting ad hoc networks comprising nodes separated by multiple hops, continuity of connectivity within a single communication link over the network, etc. The apparatus and method of operating the apparatus may also comprise dynamically performing the adjusting step resulting from repeating the calculating step over time.

Psycho-Linguistic Statistical Deception Detection From Text Content

An apparatus and method for determining whether a text is deceptive may comprise analyzing a body of textual content known to be one of text containing true content and text containing deceptive content; identifying psycho-linguistic cues that are indicative of a text being deceptive; statistically analyzing, via a computing device, a given text based upon the psycho-linguistic cues to determine if the text is deceptive. The apparatus and method may further comprise weighting the psycho-linguistic cues and statistically analyzing based on the weighted psycho- linguistic cues. The statistically analyzing step may be performed using one of a cue matching analysis, a weighted cue matching analysis, a Markov chain analysis, and a sequential probability ratio testing binary hypothesis analysis. The psycho-linguistic cues may be separated into categories, including increasing trend cues and decreasing trend cues and analyzed according to presence in a category from within the categories.

Human-Factors Driven Internet Forensics: Analysis And Tools

An apparatus and method for determining whether a text is deceptive has a computer programmed with software that automatically analyzes a text message in digital form for deceptiveness by at least one of statistical analysis of text content to ascertain and evaluate psycho-linguistic cues that are present in the text message, IP geo-location of the source of the message, gender analysis of the author of the message, authorship similarity analysis, and analysis to detect coded/camouflaged messages. The computer has access to truth data against which the veracity of the text message can be compared and a graphical user interface through which a user of the system can control the system and receive results concerning the deceptiveness of the text message analyzed by the system. The computer may be connectable to the Internet and may obtain the text to be analyzed either under the control of the user or automatically.

Data Hiding Based Messages And Advertisements

A steganographic message/advertisement embedding method is presented that can be used for contextual and targeted advertising supporting unobtrusive and on-demand message/advertisement delivery. The present invention presents over two client devices, the method includes receiving, on a first client device, a primary multimedia presentation with a plurality of steganographic codes embedded therein; whereby the steganographic code is not perceivable during a rendering of the multimedia presentation and the steganographic code is associated with at least one secondary multimedia presentation. Next; the primary multimedia presentation is rendered on the first client device. The first client device receives a user selection to select at least one of the steganographic codes. In response to the user selection, a secondary multimedia presentation is presented to the user in response to receiving the user selection, wherein the second multimedia presentation is presented over a second client device which is distinct from the first client device.
