Watermark embedding and extracting method for protecting documents

EP3477578A1
Go to patent

Document integrity and authenticity

Watermark embedding and extracting method for protecting documents.
A method for watermarking documents comprising:
identifying and locating spaces in a received original document (10) by a location analysis (110) module which distinguishes between intra-word spaces and inter-word spaces;
minimizing an error probability of interference between intra-word spaces and inter-word spaces in the watermarked document (20) by an optimization module (111);
encoding (113) the message (30) into codewords and encoding (114) the codewords into the watermark;
Embedding the watermark to generate (115) the watermarked document (20) by modifying the intra-word spaces and inter-word spaces of the original document (10).

A method and a system for encrypting wireless communications including authentication

EP3435589A1
Go to patent

Security of wireles networks

A method and a system for encrypting wireless communications including authentication.
The method comprises a) setting configuration parameters for a wireless connection; b) receiving, by a networking device (20), a request for the wireless connection to said communications network from a computing device (10); c) receiving, by the computing device (10), biometric credential information from the user (1); d) generating, by both devices (10, 20) a temporary passcode taking into account biometric information of the user (1), a random string and a temporal factor; e) sending, by the computing device (10), to the networking device (20), a device address thereof and an encrypted data packet containing a given text, said data packet being encrypted with an encryption key corresponding to the temporary passcode generated by the computing device (10); f) checking, by the networking device (20), whether the received device address of the computing device (10) is stored in a register; and g) establishing the wireless connection if all the parameters match.

Certifying documents with integrity and authenticity guarantees and computer programmes thereof

EP3379440A1
Go to patent

Document integrity and authenticity

A computer implemented method for automatically certifying documents with integrity and authenticity guarantees and computer programmes thereof.
The method comprising: receiving, by a second computer (20), a document (Do) to be certified, identifying it with metadata and computing a first cryptographic function (ho); sending, by the second computer (20), the first cryptographic function (ho) to a third computer (30) hold within a distributed ledger; receiving, by the second computer (20), a message digest (hro) corresponding to an identifier of having stored the first cryptographic function (ho) in the third computer (30); computing, by the second computer (20), a key (K), said computed key (K) being decoded into a watermark, which is applied to the document (Do) providing a modified document (Dw); sending, by the second computer (20), the modified document (Dw) to the first computer system (10); computing, by the second computer (20), a second cryptographic function (hw), and sending it and the modified document (Dw) to the third computer (30); the second computer (20) receiving a message digest (hrw) corresponding to an identifier of having stored the (hw) and (Dw).

Method, system and application for improved authentication for mobile device users

EP3484116A1
Go to patent

User authentication

Method, system and application for improved authentication for mobile device users.
Present invention provides a method, system and application for providing authentication of a mobile device user, based on the measurement of electromagnetic fields modified by a pre-established movement of a specific magnetic token associated to the user. This univocal process will be able to obtain new authentication factors, including something that the user owns (i.e., the token), something that the user knows (i.e., the interaction between the token and the device), and somewhere that the user is (i.e., where the interaction takes place).

Go to patent

Document integrity and authenticity

Method and system for detecting malicious programmes integrated into an electronic document.
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.
