Abstract: A method and/or a system for synchronizing data across immutable and mutable data storage systems. The system provides an endpoint configured to receive messages associated with database actions from client devices. Responsive to receiving a message associated with a database action via the endpoint, the system routes the message to an action queue. The system transmits the message from the action queue to multiple data engines corresponding to multiple data storage systems that store data, causing the multiple data engines to perform the action based on the message. The multiple data engines include a mutable data engine corresponding to a mutable data storage system and an immutable data engine corresponding to an immutable data storage system. The system tracks the action queue to determine an action performance speed of each data engine.

Abstract: A method or a system for validating digital ownership in immutable databases via physical devices. The system receives a request for accessing a secure resource from a client device of a user of an immutable database, and requests a wallet address associated with a wallet of the user from the client device of the user. Responsive to receiving the wallet address, the system requests an identifier (ID) token from the immutable database based on the wallet address, the ID token containing a first set of identity data of the user. The system also requests a second set of identity data from the client device. The system compares the first set of identity data with the second set of identity data to determine whether there is a match. Responsive to determining that there is the match, the system grants the user a permission to access the secure resource.

Abstract: It describes an article and method for creating a optical effect of moving images, which is produced when the angle of light reflection is changed on surfaces with embossed structures, characterized by: a) providing a metallic substrate with brightness (10); b) embossing on the substrate (10) surface (15) at least a first profile (20) and a second profile (30), which includes at least two reliefs (22, 24, 26), (32, 34, 36) being said second profile (30) adjacent to the first profile (20) and spaced apart from each other at a predetermined distance (40); c) obtaining an image by light reflection produced in the reliefs of the profiles (20 and 30) at an angle of reflection “?1” which results in a visual view of a first relative distance “X1” between the profiles (20 and 30); d) obtaining a reflection image produced in the reliefs of the profiles (20 and 30) at an angle of reflection “?2”, resulting in the visual view of a second relative distance “X2” between the profiles (20 and 30), wherein the movement of th

Abstract: Methods for certifying a security document comprising the steps of: a) selecting a set of unique characteristics, obtained as the result of the variations in the manufacturing process and supplies, b) getting a digital image of a security document and obtaining data of the relative position between features selected from different manufacturing processes (register), c) constructing a message by measuring the register of selected features from the document and the document ID data, d) constructing a hashed message, the hashed message being the message obtained after being encoded by means of a unidirectional cryptographic hash function, e) encrypting the hashed message using a public key cryptographic system to obtain a digital certificate by means of a private key, and f) storing the digital certificate in an external database.
