Abstract: A method for controlled production of an array of planar microparticles with the multiplexing of molecules on the surface thereof, intended to function as molecular sensors and/or actuators and a matrix (array) of microparticles, the surface thereof being printed with all of the molecular components required to provide the surface with functionality. Different molecular elements are multiplexed on the surface of each particle while they are supported on a substrate by means of a structural foot engraved below the particle. These microparticles can be released mechanically from the support on which they are produced using a controlled mechanical rupture method which is not chemically aggressive and therefore does not affect the molecules previously printed on the surface. The array and the particles contained therein offer great versatility in both chemical and/or biological applications.

Abstract: The present invention relates to the detection of malicious software in electronic documents and comprises: detecting an executable code in the electronic document provided to a client module; extracting information from the electronic document comprising the executable code and metadata of the electronic document; creating a binary vector associated with the electronic document; comparing, in a classifier module (200), the binary vector with one or more groups of vectors previously classified and stored in a database (400); classifying the vector in one of the groups, where each group has associated therewith a verdict about the presence of malicious software; and determining that the document contains malicious software depending on the verdict associated with the group in which its associated vector has been classified.

Abstract: According to an example aspect of the present invention, there is provided a method, comprising: generating, based on source media content, a media vector comprising one or more privacy-controlled components, wherein each component is a partially modified version of the source media content such that at least some different privacy-controlled visual media content parts of the source media content are removed, substituted or hidden at different privacy-controlled components, and assigning for each of the components privacy control information.

Abstract: A procedure to broadcast digital multimedia contents to subscribers, where a first digital data transport stream broadcast to subscribers from a head end (12) via a first telecommunications network other than a telecommunications network based on an Internet IP protocol is received in a customer device (15); transmission from a first retransmission unit (153) of a lost packet petition message to a second retransmission unit (132) contained in a service application unit (13) connectable to the customer device (15) via a second telecommunications network (11) based on an Internet IP protocol; in response to the lost packet petition message from the first data transport stream, transmission of a second digital data stream that comprises at least one packet lost form the first digital data transport stream.

Abstract: A procedure to broadcast digital multimedia contents to subscribers, where a first digital data transport stream broadcast to subscribers from a head end (12) via a first telecommunications network other than a telecommunications network based on an Internet IP protocol is received in a customer device (15); transmission from a first retransmission unit (153) of a lost packet petition message to a second retransmission unit (132) contained in a service application unit (13) connectable to the customer device (15) via a second telecommunications network (11) based on an Internet IP protocol; in response to the lost packet petition message from the first data transport stream, transmission of a second digital data stream that comprises at least one packet lost form the first digital data transport stream.

Abstract: A procedure for broadcasting multimedia digital content to subscribers, in which a first transport stream of digital data is transmitted from a header source (12) through a first telecommunications network differing from a telecommunications network based on an IP internet protocol to subscribers and is received in a customer device (15); transmission from a first channel change unit (153) of a first channel change message to a second change unit (132) of a service application unit (13) connectable to the device (15) through a second telecommunications network (11) based on an IP internet protocol; in response to a channel change message received by the first change unit (153); transmission of a second digital data stream associated with the desired channel, which begins in a key frame stored in a second storage unit (133) of the server (13), in response to the reception of the first change message received in the second channel change unit.

Abstract: Apparatus for encrypting a stream of audiovisual data generated by an encoder (11); comprises an encrypter (113) module that analyses the data stream to determine if said stream includes at least one slice relative to a layer of video codification; for encrypting at least a set of bit nearby or adjacent to a slice header; and inserts the generated encrypted set of bit into the data stream that will be transported by a digital telecommunications network (12) to a customer's local equipment.
