A distributed transaction processing system, comprising a peer node associated with a blockchain network. The peer node may be adapted to record join-time parameters for a plurality of blockchain nodes, compare a first join-time parameter for a first node of the plurality of blockchain nodes to a remainder of the join-time parameters for a remainder of the plurality of blockchain nodes, calculate, based on the comparison, a transaction signature probability (TSP) for one or more nodes within the plurality of blockchain nodes, select according to the calculated TSPs, a signature node from among the one or more nodes having calculated TSPs to sign a transaction block, and calculate, by the selected signature node, a digital signature for the transaction block.

Enabling consensus in distributed transaction processing systems

A computer-implemented method, system and computer program product for creating virtualized data assets. A copy of an extract, transform, load (ETL) or an extract, load, transform (ELT) job definition is created. Furthermore, a table function is created in which the table function is configured to trigger the execution of a copy of the ETL/ELT job definition, to read the resulting data from executing the copy of the ETL/ELT job definition and to return the resulting data (data sets), such as in a queue in a federation server. After receiving a query from a user based on a virtual view in which the query includes the ETL/ELT job definition, the table function is executed which triggers execution of the copy of the ETL/ELT job definition. Data sets are then produced by executing the copied ETL/ELT job definition, which is read and returned to the user in the virtual view.

Creating virtualized data assets using existing definitions of ETL/ELT jobs

Providing an automatic mechanism of invalidating false-positive indications of certain identified portions of source code to reduce the number of errors in a security report. Certain embodiments of the present invention utilize static security scanning as a mechanism for automatically determining which portions of the identified source code contain potential vulnerabilities, and whether these identified portions of the source code are correctly or incorrectly identified with a false-positive indication.

False-positives invalidation and static security scans without scanning based on regular scan history in pull requests

A computer-implemented method for searching for a similar image in an image database includes receiving a query image, computing a value of a similarity measure of the query image, comparing the value of the similarity measure of the query image with metadata of the partitions, discarding at least one partition of the image database based on the comparison of the value of the similarity measure of the query image with the metadata, comparing the images of at least one of the remaining partitions with the query image, and selecting at least one image of the at least one partition of the remaining partitions as the similar image based on the comparison of the images of the at least one of the remaining partitions with the query image.

Method for searching similar images in an image database using global values of a similarity measure for discarding partitions of the image database

Utilizing an Information Analyzer to profile data in order to identify data assets that contain executable code for the purpose of ensuring the security and integrity of the profiled data. The results of the data profiling process can be used by security policies to reduce the risks of malicious code execution attacks.
