In one embodiment, a system, apparatus and a method is described, the system, apparatus and a method including, a storage device and a memory operative to store target content items, a comparator operative to compare one content item of the target content items with the other target content items, and, at least on the basis of comparing the one content item of the target content items with the other content items of the target content items, to develop a correlation graph between each one content item of the target content items and the other content items of the target content items, and a machine learning system operative to receive the correlation graph and to output a decision, on the basis of in the correlation graph, indicating if the content items represented in the correlation graph are pirated content items or not. Related system, apparatuses and methods are also described.

Method and system for piracy detection

Methods and systems for comparing content are provided. A recognizable object which appears in frames of a reference video file is recognized. A meta-feature of the recognizable object is determined. A first vector indicative of the meta-feature of the identified recognizable object in the reference video file is created. The meta-feature of the identified recognizable object which appears in a suspect video file is determined. A second vector indicative of the meta-feature of the identified recognizable object in the suspect video file is created. A correlation between the first vector and the second vector is determined. The correlation between the first vector and the second vector is indicative of a degree of confidence that the suspect video file is a copy of the reference video file.

Method and system for comparing content

In one embodiment, a method comprises: in response to a request of a user device to access first content, sending a challenge, relating to digital video included in second content, the challenge at least indicative of positions that include a plurality of frames; receiving a response to the challenge, the response at least indicative of values; attempting to validate the response, including determining values of pixels in the digital video associated with positions indicated by at least one of: the challenge or the response, and comparing the values indicated by the response, or a function thereof, to the determined values, or a function thereof; and performing at least one action relating to access to the first content, dependent on whether or not the attempt to validate the response was successful.

Conditional content access

In one embodiment, a method comprising receiving data of a plurality of viewports generated from a content item during rendering of the content item, receiving data about at least one feature included in the content item, comparing the data of the plurality of viewports with the data about the at least one feature included in the content item, and computing a score representing to what extent the at least one feature is included in the plurality of viewports. Related apparatus and methods are also described.
