Abstract: A forensic verification system extracts a print signature via a print signature extractor from an interior of a halftone contained in an image. The system utilizes a comparator to compare the print signature to a reference signature stored in a registry to determine differences between the print signature and the reference signature. The system utilizes a forensic analyzer to perform a forensic analysis on the signatures based on the comparison to authenticate the image.

Abstract: Systems and methods associated with discussion resource recommendation are disclosed. One example method may be embodied as computer-executable instructions stored on a non-transitory computer-readable medium. The instructions may cause a computer to construct a resource network that links members of asset of online discussion resources. The online discussion resources may be linked based on user participation overlap between members of the set of discussion resources. The instructions may also cause the computer to generate content similarity scores that measure content overlap for pairs of discussion resources. The instructions may also cause the computer to generate network relevancy scores for the pairs of discussion resources based on the resource network. The instructions may also cause the computer to recommend, based on the content similarity scores and the network relevancy scores, a related discussion resource to a user when the user accesses a primary discussion resource.

Abstract: Example implementations relate to multiple payload pantograph. Some examples may include a first pattern generation engine to generate a first pattern. The first pattern may be a data-bearing pattern encoding a first payload. Additionally, some examples may include a second pattern generation engine to generate a second pattern, the second pattern (by itself or in combination with the first pattern) may represent a second payload. The second payload may be camouflaged by a combination of the first pattern and the second pattern. Some examples may also include a pantograph generation engine to generate a multiple payload pantograph including the first pattern and the second pattern. The multiple payload pantograph may include the first pattern in one of the pantograph background or the pantograph foreground.

Abstract: Author identification based on functional summarization is disclosed. One example is a system including a plurality of summarization engines, each summarization engine to receive, via a processing system, a text content to provide a summary of the text content. At least one meta-algorithmic pattern is applied to at least two summaries to provide a meta-summary of the text content using the at least two summaries. A content processor identifies, from the meta-summary, authorship features associated with the text content. An evaluator determines, for a given category, a category value of the meta-summary, the category value indicative of a similarity of the authorship features to the category. A selector selects, for the given category, a combination of meta-algorithmic patterns and summarization engines that provides the meta-summary that optimizes the category value for the text content.

Abstract: Examples disclosed herein relate to authentication based on data content and data partitions. In one implementation, a processor may execute instructions to determine the likelihood of authenticity based on partitions of the authentication data and content of the authentication data. The processor then outputs information related to the likelihood of authenticity.

Abstract: Detecting a workflow termination. An object with embedded access control is sent to a next participant in a workflow, wherein the embedded access control is provided and enforced by placing a subset of access keys for individual content-parts into a unique key-map entry for each participant, wherein the object is a Publicly Posted Composite Document. A workflow termination is detected after failure to receive a confirmation token from the next participant after a specified condition is not met.

Abstract: One example is a system including a plurality of combinations of summarization engines and/or meta-algorithmic patterns used to combine a plurality of summarizers, an extractor, an evaluator, and a selector. Each of the plurality of combinations of summarization engines and/or meta-algorithmic patterns receives content to provide a meta-summary of the content. The extractor generates a collection of search queries based on the content. The evaluator determines a similarity value of each combination of summarization engines and/or meta-algorithmic patterns for the collection of search queries. The selector selects an optimal combination of summarization engines and/or meta-algorithmic patterns based on the similarity value.

Abstract: An object potentially belongs to a number of topics. Each topic is characterized by a probability distribution profile of a number of representative items that belong to the topic. Sample items are selected from the object, less than a total number of items of the object. A probability that the object belongs to each topic is determined using the probability distribution profile characterizing each topic and the sample items selected from the object.
