Abstract: A computer-implemented method for checking the integrity of a target computer program to be executed in a computer system.

Abstract: A computer-implemented method for determining an origin of a target source code for a computer program or a part thereof. The method involves: Searching a plurality of software archives from different sources in a global computer network to find occurrences of the target source code among code files in said software archives. For every found occurrence of the target source code, the method further involves collecting key information about the matching source code files and, from the key information collected a frequency map is built that contains, for each keyword found in the key information, a keyword count value being indicative of the number of times the keyword occurs in the key information.

Abstract: Systems and methods for identifying a characteristic of an input code by converting the input code into simplified code and using the simplified code to generate snippets that can be compared to code in a database. Preferably, code is simplified by at least one of: unifying of capitalization, removing characters, and replacing at least one of a character and a keyword with an identifier.

Abstract: Systems and methods for storing data in an intermediate format for storing, converting the intermediate data format into a production data format of two data volumes, and merging the two data volumes into one data volume
