Fear of China spying on athletes' smartphones during the Beijing Olympics
21/01/2022A few weeks before the start of the Beijing 2022 Winter Olympic Games, February 4 to 20, the media in the Netherlands and the United Kingdom have confirmed that the Olympic committees of their countries have asked their athletes not to take their Smartphones and computers with them. The reason, they said, is the fear of Chinese espionage. For these reason, both sports organizations will equip all their athletes and other support personnel with new devices so that they can be connected during their stay in China, without exposing their personal data at risk. The decision by the Netherlands Committee was known in an interview in the Volkskrant newspaper, which appeared earlier this week. Geert Slot, the spokesman for the Netherlands Olympic Committee, explained that "Cybersecurity has become a much bigger topic in recent years, and China is a very special case." In addition to the Netherlands and England, Australia is known to have made a similar recommendation to its athletes, and also the United States.

How to sign a PDF document with electronic signature?
24/06/2021When a document needs to be signed by one or more people, the usual thing, until now, has been to print it and stamp by hand the necessary signatures to validate or make its content official. This requires paper, printer, ink, but above all access to the document by all signatories, which is not always easy due to geographical location, availability, timing, etc. With teleworking on the rise and a growing globalization of business, these drawbacks have become more evident than ever, although they have found a quick and effective solution in electronic signatures. What is an electronic signature for? The electronic signature is a digital validation system for documents that unequivocally identifies the signatory. The electronic signature is assimilated to the handwritten signature and therefore its digital stamping on a document gives it the same validity, as it would have had with a handwritten signature. What are the advantages of electronic signatures? Electronic signatures simplify document management processes that require the validation of documents such as pdf signatures, facilitating remote signing by one or more people regardless of where they are located, or the situation or time of day they receive them. This flexibility contributes to the efficiency and agility of this type of procedure and being a secure signature system, it is suitable and useful in many areas related to business management, administrative management, e-commerce, informed consent and many other procedures. In addition to the versatility, practicality and security of the online PDF signature, we must also point out, as a great advantage of this process, its contribution to paperless. How to sign electronically? The electronic signature is easy to implement through tools specifically designed to guarantee not only the correct validation of the cryptographic signature or signatures included in a PDF document, but also that it cannot be altered and that all the necessary signatures required by each situation can be added. Within the framework of this type of tool, the most advanced ones, in addition to being compatible with any browser and accessible from any type of device - computer, tablet, Smartphone,... -, make it easy to convert PDF any Word, Excel, JPG, PowerPoint... file for signing. They also allow users to request a verifiable digital signature, view the properties of the digital signature and send the document directly by email to the signatories and once signed, forward it to all parties to download it. In addition, to guarantee the privacy of the documents and the security of the online signatures, these transfers are made through encrypted files with TLS encryption. Also, when we sign documents using this type of tool, they offer the option of including a LTV (Long Term Validation) time stamp that certifies the validity of the signature in the long term. For all these reasons, tools for signing PDF documents with electronic signatures are now a must for companies and businesses in all areas where process optimization, security and sustainability are a priority.

QUIC, the new official network protocol to replace TCP
04/06/2021QUIC, the network protocol designed by Google, has been presented by the Internet Engineering Task Force, IETF, as a new official Internet standard to replace TCP, the current main standard. Google's QUIC (Quick UDP Internet Connections) network protocol is designed to reduce latency with retransmissions taking less time, potentially reducing the waiting time for search results by 8% on computers and 4% on mobile devices, according to the paper released by Google in 2017. QUIC will replace TCP, the current main standard of the Internet since 1974 - when it was still Arpanet - and on which the operation of Internet elements such as the World Wide Web (WWW) logic system, file transmission, 'emails' and remote administration depend. The new QUIC protocol has already been published by the IETF, making it an official network protocol.
