Patent number: 11943287Abstract: It is proposed a technical solution to leverage the characteristics and generally speaking, the performance of DLT networks. This solution proposes building a federation of DLT networks which work together regardless of the underlying technologies to guarantee data consistency, wider consensus and enhanced trust. The proposed solution includes, among others, a distributed transport mechanism for the exchange of control data between the different networks of the federation; and the spread and storage of “proofs of history” of the network to protect and validate the connected networks integrity.Type: GrantFiled: June 29, 2021Date of Patent: March 26, 2024Assignee: Telefónica IoT & Big Data Tech, S.A.Inventors: Alfonso De La Rocha Gómez-Arevalillo, María Teresa Nieto Galán, Jose Luis Núñez Diaz

Patent number: 11637711Abstract: Method and system which provides an increase in the basic security, performance, and trust of consensus algorithms in distributed systems based on the use of quantum technology (quantum computing mechanisms). In order to do that, it is built a quantum trust network layer using quantum entanglement between nodes to avoid the current problems in consensus algorithms.Type: GrantFiled: October 22, 2020Date of Patent: April 25, 2023Assignee: Telefónica IoT & Big Data Tech, S.A.Inventors: Alfonso De La Rocha Gómez-Arevalillo, José Luis Nuñez Díaz

Patent number: 11374763Abstract: It is proposed a technical solution to leverage the level of trust in scenarios with a high number of independent computing nodes from independent and heterogeneous DLT networks. This solution defines the technical modules required to implement a self-governed decentralized infrastructure that ensures that every participant node (computing node) in a DLT network connected to the proposed system (implementing the proposed method) can exploit additional validation and consensus policies in their transactions and smart contracts. Through the proposed mechanism they can enjoy an equivalent level of trust as if all the nodes from the connected networks were part of a single common DLT network. The proposed solution enables the implementation of dedicated validation policies to leverage the level of trust of any of the connected networks without the need of dedicated infrastructure.Type: GrantFiled: June 19, 2020Date of Patent: June 28, 2022Assignee: HIPERBARIC, S.A.Inventors: Alfonso De La Rocha Gómez-Arevalillo, José Luis Nuñez Díaz

Patent number: 10944967Abstract: Embodiments of the disclosure provide methods, apparatus and computer programs for adaptive loop filtering in an encoder and in a decoder. One method, performed in an encoder, comprises: determining filter parameters for a plurality of filters to be used in encoding a frame or slice; determining respective activity values for each of a plurality of blocks in the frame or slice, wherein each block comprises a plurality of pixels; determining respective quantization parameters for each of the plurality of blocks; selecting, for each of the plurality of blocks, a filter from the plurality of determined filters based on the respective activity value and the respective quantization parameter; and applying the filter parameters for the respective selected filters to the plurality of blocks.Type: GrantFiled: December 21, 2017Date of Patent: March 9, 2021Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Per Wennersten, Alfonso De La Rocha, Jacob Ström

Publication number: 20200235921Abstract: Method and system for recovering cryptographic keys of a blockchain network. A computing device or an element associated with the same has stored a pair of cryptographic keys representative of the identity of the user in a blockchain network, including a public key and a private key. An identity manager maintains a registry of the user in a distributed directory. When a request from the user is received due to the loss/theft of their private key, the information on the public key of the user is eliminated from the registry and the user is revoked as the owner of a smart contract, a new pair of keys is generated, stored in the device or in said element; and the user is identified and authenticated. Once correctly authenticated, the manager receives the new public key of the user, updates the registry and updates the ownership of the smart contract.Type: ApplicationFiled: December 23, 2019Publication date: July 23, 2020Applicant: TELEFONICA DIGITAL ESPAÑA, S.L.U.Inventors: Alfonso De La Rocha Gómez-Arevalillo, Jose Luis Nuñez Diaz
