Abstract: A method of encoding information (10) by using null-sized spaces, ZWSP, from an original text (11), transforming it into a text with hidden information (12), wherein the encoded information (10) is integrated by adding the ZWSP used in encoding. Hidden information encoded in a text ZWSP (120) can contain: Text block number, pre-set block size, text and author metadata, calculated text hash, and a time stamp. A text monitoring system (42) comprising a decoder module (30) that implements the reverse method for decoding information (10) from a received text detecting ZWSP in at least part of the text and extracting the information (10) to obtain the original text (11) using the detected ZWSP. The monitoring system (42) can additionally comprise an encoder module (20) that uses the ZWSPs and be integrated into a remote messaging server (41).

Abstract: A method and system for providing identity and authentication to a data-generation device is disclosed. The method comprises the provision, by a computing platform, of a beacon for a data-generation device, said beacon including an identification code and providing the data-generation device with connection and security functions; activating, by means of the computing platform, the data-generation device by using and verifying a physical access challenge; verifying, by means of the beacon, a state of activation of the data-generation device by using the identification code; providing, by means of the computing platform, a digital certificate to the beacon; and sending, by means of the beacon, a security verification to the platform, such that the data-generation device can securely establish future communications with remote computer equipment.

Abstract: The system includes a passive card (10) configured to store a first portion of an authentication or authorization code via a set of capacitive points (11) included on its surface; and a portable computing device (20) having a capacitive screen and being configured to store a second portion of said authentication or authorization code. Such that, once the user (1) has requested access to a specific service or to a specific operation and when the passive card (10) is in contact with the capacitive screen, the portable computing device (20) is further configured to read at least some of the set of capacitive points (11), decoding the first portion, and cryptographically signing the decoded first portion using said stored second portion, providing the authentication or authorization code, which is used as cryptographic key to grant access to said specific service or specific operation to the user (1).
